First check whether your exact tablet supports video output: a USB-C port by itself does not guarantee that it can send a picture to a monitor. If it does, connect it to the monitor with a compatible cable or adapter, choose whether you want screen mirroring or a desktop-style display, then connect a keyboard and mouse by Bluetooth or through a compatible hub. The details—and available resolutions—depend on the tablet model.
What to check before connecting your tablet
Find the tablet’s exact model name and port, then check its manufacturer’s specifications for external display support. Android’s connected-display and desktop-windowing features vary by device and are not available on every Android tablet; USB-C alone is not proof of video output. Google’s Android connected-display guidance explains the feature’s device-dependent behavior.

- Check that the tablet supports video output over its port or supports the wireless display method you plan to use.
- Identify the monitor’s available inputs, such as HDMI or USB-C.
- Decide whether you want the tablet screen mirrored or a separate desktop-style session.
- Check the tablet and adapter specifications for the resolution and refresh rate you want. Also check whether the display or hub can charge the tablet.
How do I connect my tablet to an HDMI monitor?
- Choose a compatible USB-C-to-HDMI adapter or cable if your tablet supports video output and the monitor has HDMI. Apple documents HDMI output from supported iPads through a USB-C-to-HDMI adapter; Samsung documents HDMI adapters and HDMI-to-USB-C cables for supported Galaxy tablets.
- Connect the adapter or cable to the tablet and the HDMI end to the monitor.
- Use the monitor’s input/source control to select the HDMI port you connected.
- Unlock the tablet if prompted, then check for a display prompt or desktop-mode option. On a supported Galaxy tablet, if the monitor mirrors the tablet, Samsung says to select DeX through the notification or Quick Settings controls.
- Check the displayed image, resolution, and any display arrangement settings available on your tablet.
For USB-C displays, a compatible USB-C cable may be an option where both the tablet and monitor support it. Apple says iPad uses DisplayPort for USB-C display support. Its specifications vary by model: some supported iPads can output up to 4K, certain older Pro models up to 5K, and specified Pro and Air models up to 6K. HDMI output limits also vary by model and adapter; Apple lists up to 4K at 60 Hz for specified newer models and up to 4K at 30 Hz for several others. Check Apple’s USB-C iPad support page for the exact model and connection conditions rather than assuming one resolution applies to every iPad.

Will my tablet mirror the screen or extend to a desktop?
Those are different outcomes. Mirroring shows the tablet’s screen on the monitor. A separate desktop-style session can provide a different workspace on the external display. Which behavior is available depends on the tablet, its software, and its settings.

Can I use a keyboard and mouse with my tablet?
Yes, if the tablet supports the input devices and connection method. Bluetooth avoids running input cables to the tablet; a compatible USB hub or dock can connect wired peripherals where supported. Pair Bluetooth devices in the tablet’s Bluetooth settings, or connect wired devices to the hub or dock and then connect it to the tablet.

Which connection method should you choose?
| Setup | What it provides | Key check |
|---|---|---|
| USB-C-to-HDMI adapter or cable | Wired connection to an HDMI monitor; supported tablets may mirror or offer a desktop-style mode. | Confirm tablet video output, adapter compatibility, and the desired resolution. See Apple’s iPad USB-C guidance or Samsung’s DeX instructions. |
| USB-C display connection | Wired connection to a USB-C display on supported devices. | Confirm display support and model-specific output capability; Apple documents DisplayPort over USB-C on iPad. |
| Compatible USB hub or dock | Can provide HDMI output and ports for wired input devices; some setups may also support charging. | Verify the particular tablet and hub support video, peripherals, and charging as needed. Apple notes that some USB-C displays can charge iPad, while some accessories may request more power and affect battery life. |
| Wireless Samsung DeX | Desktop-style DeX connection to compatible Samsung TVs and smart monitors. | Requires a supported Galaxy tablet and compatible display. Samsung notes that a short distance helps reduce stuttering or lag and that touchscreen displays are not compatible with DeX functionality. |
| Bluetooth keyboard and mouse | Wireless typing and pointer input, independently of whether video is wired or wireless. | Pair in the tablet’s Bluetooth settings and confirm the tablet supports the devices and desired workflow. |
How to troubleshoot a tablet that will not connect
- The monitor says no signal: Confirm the monitor is set to the input you used, reseat both ends of the cable, and verify that the exact tablet supports external video output. A USB-C connector alone does not establish compatibility.
- The screen mirrors but you expected a desktop: Check whether the tablet supports desktop features. On a supported Galaxy tablet, select DeX from the notification or Quick Settings controls; Android desktop-windowing behavior varies by device.
- The keyboard or mouse does not respond: For Bluetooth, check that each device is paired in tablet settings. For wired input, verify that the tablet and hub support the devices. With Samsung DeX, do not use wired keyboard or mouse devices with the DeX cable method; Samsung documents Bluetooth input for that case.
- The picture is not at the expected resolution: Check the tablet’s model-specific output capability and the adapter or cable specifications. A different connection path may have different limits.
- The tablet battery drains while connected: Some displays or docks can provide power, but charging support depends on the equipment. Apple notes that some accessories may request more power and affect iPad battery life.
