Connecting two older consoles to one television is mainly a compatibility exercise, not a matter of finding the biggest adapter. Identify the video signal each console actually produces, identify the inputs your TV accepts, and then choose a path that preserves that compatibility. You can connect each console directly to a different matching TV input, share one analog input with an AV switcher, or convert the consoles to HDMI with a compatible scaler. A switcher selects a source; a scaler converts a signal for a different display input. They are not interchangeable.
The exact console models, regional standards, existing cables, and television model determine the correct wiring. A setup that works for two composite consoles may fail completely when one system uses RGB, component, S-Video, or RF. Use the decision tree below before buying hardware.

Start with an inventory of every connector
Do not choose equipment from plug colors alone. A yellow RCA plug usually carries composite video, but some consoles use proprietary multi-out sockets, and red/white plugs carry audio rather than video. Write down the exact console model, the cable you own, and every input printed on the television.

Check whether the socket is proprietary and requires a model-specific cable.
- Television side: note HDMI, composite/CVBS, S-Video, component/YPbPr, SCART, antenna/RF, and any shared audio-video jack. Some TVs place analog inputs behind an adapter dongle.
- Signal details: record the console’s region (for example, NTSC or PAL) and the cable standard. A connector can fit while the signal remains incompatible.
- Existing accessories: label power supplies, extension leads, audio cables, and adapters separately. A power adapter is not a video converter.
Look at both ends of every cable. A console may have a proprietary socket on one end and three RCA plugs on the other, while another cable for the same-looking console socket may carry S-Video or RGB instead. The TV input label describes what the television expects, not necessarily what a cable is carrying.

Your TV manual is the authority for its own input labels. Philips’ support documentation for the specific 32PFL7694H/12, for example, lists HDMI, YPbPr/component, SCART, S-Video, and CVBS and explains selecting devices with the remote’s Source button. That model-specific list does not describe every Philips set or any other brand. Check whether a jack is shared, whether an adapter is required, and whether the TV needs an on-screen setting to activate a particular analog input.
Map the signal before buying anything
Make a simple three-column list: console and region, cable/output format, and available TV input. Then draw the intended route from console to screen. Every arrow must preserve the signal type until a device explicitly converts it. For example, “composite console → composite switcher → composite TV” is a complete route, while “composite console → component TV jack” is not.
Also count the number of sources at each stage. Two consoles need two usable input paths somewhere. A single-input scaler can serve both systems only when a compatible selector is placed before it, or when the scaler itself has multiple selectable inputs. If the consoles use different formats, count one compatible conversion path per format unless the product documentation explicitly lists both.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Choose the wiring path that matches your equipment
| What you have | Required path | What the box does | TV connection |
|---|---|---|---|
| Two consoles and two matching analog TV inputs | Console 1 → TV input 1; Console 2 → TV input 2 | No extra box; the TV selects sources | Analog cables directly |
| Two consoles with the same analog format, one matching TV input | Both consoles → compatible AV switcher → TV | Selects which analog source reaches the TV | Composite, S-Video, component, or another matching analog input |
| Analog consoles and an HDMI-only TV | Consoles → compatible selector (if needed) → scaler/converter → HDMI TV | Converts the console signal and usually scales it for HDMI | HDMI |
| Consoles with different formats | Separate compatible conversion paths, then an HDMI switcher or separate TV inputs | Each converter handles only the signal it supports | One or more HDMI inputs |
Use the first path whenever it is available: fewer boxes mean fewer compatibility checks and fewer points of failure. A selector is useful when the TV has too few matching sockets. A scaler is necessary when the TV cannot accept the console’s analog signal. Adding a switcher to an HDMI-only route does not eliminate the need for conversion.
Path 1: use the TV’s matching analog inputs
This is the simplest and usually the least expensive arrangement when the television already accepts both console signals.
- Turn off both consoles and the TV.
- Connect the first console to a matching TV input. Composite requires video and left/right audio; component requires the correct Y, Pb, and Pr video leads plus separate audio; S-Video still needs audio leads.
- Connect the second console to another matching input. Do not plug a composite video lead into a component jack merely because the plugs look similar.
- Power on the TV, press Source, Input, or the equivalent button, and select the socket used by the running console.
- Label the inputs in the TV menu if the set permits it.
Only one source is displayed at a time, but no cable swapping is required. If the TV has one shared jack that changes function through a menu or adapter, follow the model’s manual rather than assuming all analog sockets are active simultaneously.
Test each console independently before trying to switch rapidly between them. With the first console running, confirm both picture and sound, then turn it off and repeat with the second. If one works and the other does not, you have isolated the problem to that console’s cable, signal, region, or output rather than to the TV’s source-selection procedure.

Path 2: share one analog input with an AV switcher
Use this setup when both consoles output the same format and the TV has only one input of that format. For two composite systems, buy a composite AV switcher with at least two inputs and one output. Connect each console’s video and audio leads to an input, then connect the switcher’s output to the TV’s composite input.
- Match the switcher to the signal: a composite switcher is not automatically suitable for S-Video, component, SCART/RGB, or RF.
- Connect Console 1 to switcher input 1 and Console 2 to input 2.
- Connect the switcher output to the TV’s corresponding input, preserving left/right audio channels.
- Power the TV and the desired console, then press the switcher’s button for that input.
- Select the TV input once; change systems with the switcher thereafter.
An AV switcher only changes which source is electrically connected. It does not turn composite into HDMI, remove interlacing, or increase resolution. Passive units may need no separate power; powered units can be useful for longer cables but still require signal compatibility. A powered switcher is not automatically a scaler, and a box described as an “AV selector” may still support only one particular analog format.
Keep the unused console switched off while testing. Some equipment can pass a signal from a powered-off source, but relying on that behavior makes diagnosis harder. Label the switcher buttons and the TV jack so a visitor can select the correct system without tracing cables.
Path 3: convert analog video for an HDMI-only TV
If the television has no usable analog input, the console signal must reach a converter or scaler that explicitly supports it. A generic “retro HDMI” label is not enough: verify support for composite, S-Video, component, SCART/RGB, or RF as appropriate. Also verify the output connector, because a device that produces an analog output cannot feed an HDMI-only television without another conversion stage.
Recommended Free Tools
Two consoles using the same format
Connect both consoles to a matching analog selector, connect the selector’s output to the scaler’s analog input, and run the scaler’s HDMI output to the TV. If the scaler has multiple selectable analog inputs, it may replace the separate selector. The TV remains on the scaler’s HDMI input while you switch consoles on the analog side.
For a composite pair, the route is console video and audio leads → composite switcher → scaler’s composite input → HDMI cable → TV. Confirm that the scaler carries audio through HDMI or provides a separate audio output that your TV can use. If the TV shows a picture but remains silent, audio may have been left at the switcher or may require a separate connection.
Two consoles using different formats
One scaler may not accept both signals. Use a separate compatible converter for each format, connect each converter to an HDMI switcher, and connect the HDMI switcher to the TV. Another option is to leave one converter on a second HDMI socket and select between TV inputs. Exact wiring depends on the inputs and outputs of the equipment you buy; never assume an adapter designed for composite also accepts component or RGB.

Separate conversion can cost more and adds another power supply, but it avoids forcing an unsupported signal through a universal-looking adapter. Preserve each console’s native output until the device specifically designed to handle it. If one source is RF, an RF-compatible path may be required before any modern HDMI conversion; do not substitute a composite switcher.

Before buying, check three specifications: supported input format, supported resolution and refresh standard, and output connector. Older consoles commonly produce 240p or 288p progressive signals, or 480i/576i interlaced signals. A converter that accepts only 480i may fail with a 240p game, while one that accepts only composite will not accept RGB from a SCART cable.
RetroTINK’s documentation for the 2X Pro illustrates the level of detail to look for. It lists composite, S-Video, and component inputs; digital video output; and support for 240p, 288p, 480i, and 576i inputs. It does not accept 480p or higher input. The manufacturer also warns that 480i bob deinterlacing can flicker. The 2X Pro is described as a legacy product, and its page listed $139.99 when accessed in 2026; both availability and price are volatile, so verify them before purchase.
Those specifications are an example, not a guarantee that the 2X Pro is right for every console. If your console outputs a different format, uses a different region, or produces a timing the scaler does not list, choose another compatible path. Do not buy on the assumption that every standard-definition signal is interchangeable.
Region and cable qualifications
NTSC and PAL systems can differ in resolution, refresh rate, connector wiring, and color encoding. A scaler must support the standard produced by your console and the TV must accept the scaler’s HDMI output. The same product documentation gives an optional N64 S-Video cable for NTSC consoles and flags certain out-of-spec composite signals. It also identifies potential problems with Sega Genesis and PS1/PSOne composite output and provides different cable guidance. Treat those notes as compatibility requirements, not optional fine print.

Region information should be checked on the console, the cable listing, and the converter documentation. A cable made for one regional model may fit another model while carrying a differently wired or unsupported signal. When a manufacturer specifies a particular cable for a console family, follow that specification instead of relying on a visually similar lead.
How to compare switchers and scalers
| Specification | Question to ask | Why it matters |
|---|---|---|
| Accepted signals | Does it explicitly list my console’s composite, S-Video, component, SCART/RGB, or RF output? | Similar plugs do not guarantee the same electrical signal. |
| Input count | Are there at least two usable console inputs? | One input means you will still unplug cables or add another selector. |
| Output | Does it provide the connector my TV accepts, usually HDMI? | An analog-only output cannot feed an HDMI-only television. |
| Resolution and region | Are 240p/288p/480i/576i and the console’s NTSC or PAL standard supported? | Unsupported timing produces a blank, unstable, or distorted picture. |
| Function | Is it a selector, a converter/scaler, or both? | A selector routes; a scaler converts and may deinterlace or line-double. |
| Audio handling | Does audio pass through with the selected video source? | Some video adapters require separate audio routing. |
| Power and controls | Does it need its own power supply, and can you select inputs from the front or a remote? | Power and control requirements affect placement and everyday switching. |
For a same-format composite setup on a TV that already has composite input, a basic composite switcher may be all you need. An HDMI-only TV requires a suitable converter or scaler as well. Image quality, latency, and price vary by hardware, but no current market ranking or hands-on performance comparison is established here. Compare the total route, including required cables and additional selectors, rather than comparing the price of one box in isolation.

Plan power, placement, and cable length
Every active scaler, converter, or powered switcher adds a power connection. Place those devices where their status lights and input controls remain accessible, and keep power supplies identified with the device they belong to. Do not confuse a scaler’s power adapter with a console power supply.
Keep video and audio leads fully seated and avoid straining proprietary console sockets. Long or damaged analog cables can make a marginal signal appear to be a scaler failure. If the route works with one console close to the TV but fails after adding an extension, remove the extension during diagnosis. Once the basic route is stable, add extensions one at a time.
First-time setup checklist
- Confirm the console’s exact model and region.
- Confirm the cable’s signal type, not just its plug colors.
- Check that every intermediate device lists that signal and resolution.
- Count inputs and outputs so both consoles have a permanent route.
- Connect video and audio completely before powering on.
- Set the TV to the correct source or HDMI input.
- Turn on one console at a time while testing.
- Save input labels or switcher positions once the picture and sound work.
- Write down the working switcher and TV selections for future use.
Troubleshoot a blank screen or missing sound
The TV says “No signal”
- Verify the TV is on the socket or HDMI port actually used.
- Check the selector’s chosen input and confirm the console is powered.
- Bypass the selector temporarily and connect the console directly to a matching TV input.
- If a scaler is present, confirm that it accepts the console’s format and resolution; do not blame the TV until this check is complete.
- Confirm that the scaler itself is powered and that its HDMI output is connected to the TV, not to another input on the scaler.
Picture appears but audio is absent
- Confirm red and white audio leads are in the same source path as the video.
- Check whether component video is connected with separate audio; the red component lead is not necessarily the red audio lead.
- Try the TV’s external-speaker and mute settings.
- If an HDMI scaler is used, check whether its audio is embedded in HDMI or must be routed separately.
Picture rolls, flickers, or has incorrect colors
- Check NTSC/PAL compatibility and the console’s region.
- Replace a questionable proprietary cable with one specified for that model.
- Try the console directly on a compatible input to isolate the scaler.
- Remember that some 480i bob-deinterlaced output can flicker, and that out-of-spec composite signals may need a different cable or converter.
- Check that component Y, Pb, and Pr leads are in their matching jacks; a misplaced lead can produce wrong colors even when a picture is visible.
One console works and the other does not
The working console proves only that part of the chain functions. Compare the failed console’s format, resolution, region, and cable against the selector and scaler specifications. Test it alone, then add the other device after a stable picture is established. If the two consoles use different standards, do not assume that a switcher failure is the cause; the unsupported format may be the entire problem.
When a separate TV input is the better answer
If one console needs RGB or RF and the other uses composite, forcing both through one conversion chain can add cost and failure points. Keep the incompatible system on a separate compatible TV input, or give each console its own converter and select the resulting HDMI sources with an HDMI switcher. The cleanest setup is the one that preserves each console’s native signal until the device specifically designed to handle it.
This approach can also be preferable when one console already works directly with the TV. Leave that connection untouched and convert only the system that lacks a matching input. You avoid buying a second converter and make troubleshooting easier because each console has a shorter, independent route.
Frequently overlooked pitfalls
- Assuming every three-plug lead is composite: component video also uses three video plugs, and its separate Y/Pb/Pr signals cannot be substituted for composite.
- Buying by the word “retro”: marketing terms do not prove support for your signal, region, or resolution.
- Forgetting audio: S-Video and component carry video only, so their audio leads must follow the selected source.
- Using the wrong regional cable: a physically compatible plug can still be wired for a different model or region.
- Expecting a selector to improve quality: it routes a source; it does not scale, deinterlace, or convert it.
- Ignoring legacy-product status: a documented device may have changed availability or price, so confirm current support and specifications before ordering.
Frequently Asked Questions
Can one converter handle two consoles?
Only if it has two compatible inputs or you place a matching selector before it. A converter with one composite input cannot accept a second console that outputs S-Video, component, RGB, or RF without additional compatible hardware.
Do I need to unplug a console when switching systems?
No. With two direct TV inputs, use the TV’s Source control. With one shared analog input, use an AV switcher; with HDMI conversion, use a compatible analog selector, the scaler’s input control, or an HDMI switcher.

Why does a cable fit but produce no picture?
Physical fit does not prove signal compatibility. The console, cable, selector, scaler, and TV must all support the same format, resolution, and regional standard.
Can I connect a composite console to a component input?
Not merely because both use RCA-style plugs. Composite and component are different signals. Use a matching composite TV input or a converter that explicitly accepts composite.
What if one console uses PAL and the other uses NTSC?
Check that each direct input, switcher, and scaler supports the relevant regional standard. If one conversion path cannot support both, use separate compatible paths and select them at the TV or with an HDMI switcher.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsIs an AV switcher enough for an HDMI-only television?
No. An AV switcher only selects among compatible analog sources. You also need a scaler or converter that accepts the selected analog signal and outputs HDMI, unless the switcher itself includes that conversion.
Why does the picture flicker through a scaler?
Verify the input timing and the scaler’s specifications. Some devices use bob deinterlacing for 480i, which can flicker, and a scaler may not properly support every 240p, 288p, 480i, or 576i source.
Should I convert both consoles even if one already works directly?
Usually not. Leave the working console on its compatible TV input and convert only the incompatible system unless a single unified HDMI route is more useful for your setup.
The Bottom Line
Start with the console outputs and the TV inputs, not with an adapter label. Use direct matching inputs when possible, a same-format AV switcher when one analog input must be shared, and a signal-specific scaler when the TV accepts HDMI only. Verify format, resolution, region, audio routing, and cable compatibility at every stage; a selector chooses a source, while a scaler converts it.
