If you need a Samsung television that is genuinely 43 inches, the 2025 Samsung QN90F Neo QLED 4K is the best-supported choice in the U.S. lineup covered here. Its exact U.S. model is QN43QN90FAFXZA. It combines a bright Mini LED-style backlight, anti-reflection treatment, 4K processing and high-refresh-rate gaming features, making it especially suitable for a bright room or a compact gaming setup. The important qualification is price: Samsung’s U.S. page displayed $1,299.99 when crawled, which is a dated listed price rather than a permanent street price.
If you can accept a screen that measures 42 inches instead of 43, Samsung’s S90F OLED is the more compelling alternative for near-perfect contrast and vivid gaming color. The QN90F remains the straightforward recommendation when the size must be exactly 43 inches.

The short answer: buy the QN90F when 43 inches is non-negotiable
Samsung’s 2025 QN90F is the clearest match for the phrase “Samsung smart TV in 43 inch.” Samsung lists a 43-inch Class Neo QLED 4K Vision AI Smart TV in the United States under model QN43QN90FAFXZA. That exact size matters: many premium small-screen televisions are sold as 42-inch models, and a one-inch difference can affect a cabinet opening, wall-mount position or desk setup.

An independent comparison identifies it as brighter in HDR than Samsung’s S90F and suitable for gaming in a bright room. Its Glare Free screen treatment is intended to reduce reflections, although no panel can eliminate every reflection in direct sunlight.

Choose the QN90F if your priorities are an exact 43-inch diagonal, high brightness, anti-reflection performance and modern console or PC gaming support. Choose the S90F only if you deliberately prefer OLED contrast and can live with a 42-inch screen. Consider an older QN90D only when its local discount, condition and warranty make the trade-off worthwhile.
What the QN90F specification actually tells you
The name “QN90F” covers regional variations, so confirm the complete suffix on the box and retailer page. The following table separates the U.S. product identity from specifications published on Samsung’s U.K. page.
| Item | QN90F information | Qualification |
|---|---|---|
| Model and year | QN43QN90FAFXZA; 2025 model | U.S. listing; regional suffixes can differ |
| Screen size | 43-inch class | Exact size confirmed in Samsung’s U.S. listing |
| Resolution | 3,840 × 2,160 (4K) | Published on Samsung’s U.K. specification page |
| Refresh rate | 120Hz, up to 165Hz | U.K. specification; verify the local variant |
| HDMI | Four HDMI inputs | U.K. specification |
| High-refresh HDMI support | 4K/165Hz on HDMI 1–4 | U.K. specification; do not assume every regional suffix is identical |
| Audio return | eARC | U.K. specification |
| Screen finish | Glare Free anti-reflection treatment | Samsung product descriptions use this feature name |
| Processing | NQ4 AI Gen3 processor and 4K AI Upscaling Pro | Features named on Samsung’s QN90F product page |
| Motion feature | Motion Xcelerator 165Hz | Samsung product-page feature name |
| Listed U.S. price | $1,299.99 | Price displayed when the U.S. page was crawled; not a guaranteed current price |
These are not promises of identical behavior in every country. Samsung can change tuners, software, energy labels, bundled accessories and model suffixes by market. Before paying, compare the exact code, panel size, HDMI capabilities, warranty terms and return window for your country.

How the QN90F performs for the situations that matter
Bright living rooms and daytime viewing
The QN90F’s main practical advantage over a small OLED is brightness headroom. Independent coverage reports higher HDR brightness than the S90F and specifically identifies the QN90F as a good choice for gaming in a bright room. That gives highlights more impact and makes the picture easier to see when daylight competes with the screen.
Glare Free treatment addresses a different problem from brightness. A brighter panel can overpower some ambient light, while anti-reflection treatment reduces the sharpness and intensity of reflected lamps and windows. Placement still matters: a window directly opposite the TV can create a visible washout, and the best result comes from positioning the screen away from the strongest light source.

Movies and dark-room viewing
Neo QLED uses a Mini LED-style backlight with local dimming rather than individually lit pixels. It can produce strong contrast, but a dark scene may show some haloing around bright objects or subtle changes as dimming zones transition. OLED has a structural advantage in a dark room because each pixel can turn off independently.
That distinction is why the S90F remains a legitimate alternative despite being 42 inches. Tom’s Guide describes the S90F as having near-perfect contrast and strong color. The choice is therefore not simply “newer model versus older model”; it is a decision between a brighter exact-size LCD-based design and a smaller self-emissive OLED design.

Color and HDR
The QN90F is designed for high-dynamic-range material, and its brightness can make specular highlights stand out in a bright room. The S90F is described as colorful in gaming and very strong in contrast. Neither description means every film, stream or game will look better in every room: source quality, viewing angle, picture mode and ambient light all influence the result.
One specific S90F limitation is the lack of Dolby Vision, noted among its drawbacks in the independent roundup. If Dolby Vision support is a deciding requirement, check the exact format support of the model sold in your market rather than assuming that every Samsung television handles the same HDR standards.
Gaming: where the 43-inch QN90F is especially convincing
A 43-inch screen can work well on a desk, in a bedroom or in a small gaming room, but only if its inputs match your equipment. Samsung’s U.K. page lists four HDMI ports, 4K/165Hz support on all four and eARC. The page also lists a 120Hz refresh rate with support up to 165Hz. Those figures are unusually useful for a small television because they cover current game consoles and high-refresh gaming PCs, subject to the capabilities of the regional model and your source device.

Match the television to your source
- Current consoles: Confirm the console’s maximum output and use an HDMI input that supports the required 4K refresh rate.
- Gaming PC: A PC must have a graphics card, cable and game settings capable of producing the selected resolution and refresh rate. A television that accepts 165Hz cannot create 165 frames per second from a slower system.
- Multiple devices: Four HDMI inputs leave more room for a console, PC, streaming box and audio system, but verify that the eARC connection is assigned to the port identified by the regional manual.
- Competitive play: Enable the television’s gaming picture mode and check whether brightness, local-dimming behavior or black levels change. The QN90F and QN90D do not behave identically in game mode.
The QN90F versus QN90D gaming trade-off
RTINGS’ comparison gives the older QN90D a slight overall edge, mainly for contrast and color vibrancy, but its gaming behavior is not uniformly better. The QN90D loses much of its HDR brightness in Game Mode, while the QN90F can show worse black levels caused by zone transitions in Game Mode. In other words, “newer” does not automatically mean better, and “better contrast” does not guarantee the best gaming picture.
If you find a QN90D at a substantial discount, inspect the panel for damage, verify the full model number, confirm that the warranty is valid in your country and test the gaming mode during the return period. A modest saving is less attractive if the older set is open-box, lacks coverage or cannot deliver the refresh rate your setup requires.
How the QN90F compares with Samsung’s nearby alternatives
| Option | What it does best | What to watch |
|---|---|---|
| 2025 QN90F, 43 inches | Exact 43-inch fit, bright-room viewing, HDR and high-refresh gaming | LCD-style local-dimming artifacts are possible; U.S. listed price was $1,299.99 when crawled, not a stable street price |
| S90F OLED, 42 inches | Near-perfect contrast, vivid color and strong gaming presentation | It is actually 42 inches, not 43; no Dolby Vision and middling built-in audio were noted |
| QN90D, previous generation | Potential bargain with a slight overall contrast and color-vibrancy edge in RTINGS’ comparison | Game Mode can reduce HDR brightness; availability, condition and warranty vary |
| M70H, 43 inches | Newer 2026 Samsung option named in the U.S. announcement | The announcement does not position it as a QN90F-class successor or provide a complete comparison |
Who should buy each model?
Buy the QN90F when exact dimensions come first
Select the QN90F when your furniture, wall space or viewing distance requires a true 43-inch set. It is also the sensible choice for a room with substantial ambient light, for people who want anti-reflection treatment, and for gamers who want the option of 4K at high refresh rates. Confirm the local model’s HDMI and refresh-rate specifications before ordering.
Choose the S90F when contrast matters more than one inch
The S90F makes sense for a dark or controllable room, film-focused viewing and gaming where pixel-level black control is more important than maximum brightness. Measure the 42-inch chassis and bezel area before assuming it will fit a space designed for a 43-inch television. Keep the Dolby Vision limitation and the independent report of middling audio in your decision.
Consider the QN90D only as a value play
The QN90D is not a default recommendation over the QN90F. It is a candidate when a reliable retailer offers a meaningful discount and you accept its Game Mode behavior. Compare the two sets with the same HDR game, picture mode and room lighting instead of relying on a model-year label.

Wait or investigate the M70H when 2026 availability is the priority
Samsung’s March 24, 2026 U.S. announcement names a 43-inch M70H Mini LED television and refreshed Neo QLED ranges. It does not name a 43-inch QN90 successor. That makes the M70H relevant context for a new-model shopper, but the announcement alone does not establish worldwide availability, detailed specifications or equivalence to the QN90F.
Buying checklist: verify these details before checkout
- Confirm the diagonal: The listing should say 43 inches for the QN90F. Do not substitute a 42-inch S90F if your space has a strict size limit.
- Read the full model code: In the United States, the QN90F identity covered here is QN43QN90FAFXZA. Your country may use a different suffix.
- Check the market-specific specification sheet: Verify resolution, refresh rate, HDMI count, 4K high-refresh support and eARC on the page for your region.
- Recheck the price: The $1,299.99 U.S. figure was a crawl-time page price. Look for the current price, stock status, delivery terms and return policy.
- Confirm warranty coverage: Make sure the warranty applies to the seller, country and exact model you are buying.
- Measure the installation space: Account for the stand footprint, bezel, cable clearance and viewing height, not just the advertised diagonal.
- Match your equipment: Count your HDMI devices and confirm that your console, PC and audio system can use the refresh rate and eARC features you want.
- Inspect returns: A clear return window is valuable for checking dead pixels, backlight uniformity, reflection performance and gaming behavior in your own room.
Setup steps for a better first impression
1. Position the screen away from direct reflections
Place the panel so windows and lamps are not directly opposite it. Glare Free treatment helps, but geometry still determines how much reflected light reaches your eyes.
2. Connect high-bandwidth devices deliberately
Use the HDMI inputs specified by your regional manual for 4K high-refresh operation. Connect an eARC sound system to the labeled eARC port rather than assuming every HDMI socket provides the same audio-return function.
3. Select the correct output on each source
Set the console or PC to 4K and the highest refresh rate that both the source and game support. If the image drops out, lower the refresh rate first and test the cable and input before changing other settings.

5. Check firmware and regional menus
Use Samsung’s on-screen update process for the model and country you purchased. Menu names and available features can vary by region, so follow the local manual rather than instructions written for another suffix.
Limitations you should understand before choosing
- Local dimming is not OLED: Bright objects on dark backgrounds can produce halos or changing black levels, particularly in gaming modes.
- 165Hz is conditional: The television can accept a high refresh rate only when the regional model, source hardware, cable and software settings all support it.
- Regional specifications differ: The four-HDMI, 4K/165Hz and eARC details cited above come from Samsung’s U.K. page; confirm equivalent U.S. or other-market specifications.
- Prices move: The $1,299.99 U.S. listing is historical page information, not a promise of today’s price.
- Availability is local: The evidence does not establish current inventory in every country or a universal retailer listing.
- Picture quality is room-dependent: Bright-room visibility favors the QN90F, while OLED’s pixel-level blacks can be more valuable in a dark room.
Why the recommendation is not simply “the newest Samsung”
Model numbers encode a family and generation, not a guarantee that every newer set wins every comparison. The QN90F is the strongest exact-size recommendation because it combines a confirmed 43-inch listing with bright-room and gaming strengths. RTINGS’ QN90D comparison shows why a discounted previous model can still be competitive in contrast and color vibrancy, while its Game Mode has a different HDR trade-off. The S90F demonstrates a second kind of exception: its OLED contrast may be preferable even though the screen is 42 inches and therefore fails a strict 43-inch requirement.
Samsung’s 2025 lineup announcement included a promotional statement from Shane Higby, Head of Home Entertainment at Samsung Electronics America: “With our new Mini LED TVs and Neo QLED 4K series, we’re offering incredible value for shoppers at every price point.” That is Samsung’s own positioning, not an independent test result, so use the model-specific checks above when deciding whether the value is right for you.
Decision guide
| Your situation | Best direction | Reason |
|---|---|---|
| Cabinet or wall opening requires 43 inches | QN90F | It is the exact-size model confirmed in the U.S. listing |
| Room is bright and you play games | QN90F | Reportedly brighter in HDR than the S90F and designed for high-refresh input |
| Dark room, movie priority, 42 inches fits | S90F OLED | Near-perfect contrast and vivid color, with no Dolby Vision |
| Large discount on an earlier premium model | QN90D, after testing | Slight contrast and color-vibrancy edge in one comparison, but Game Mode trade-offs apply |
| You want a 2026 model and can wait for details | M70H or another locally announced model | The 43-inch M70H is named in Samsung’s U.S. announcement, but its full positioning is not established there |
For most readers who typed “best Samsung Smart TV in 43 inch” and mean the size literally, start with the QN90F. Then validate the regional code, current price, warranty and HDMI specifications before purchase. Move to the S90F only when its 42-inch size is acceptable and OLED contrast is your overriding priority.
The Bottom Line
Bottom line: Samsung’s 2025 QN90F (U.S. model QN43QN90FAFXZA) is the best-supported exact 43-inch choice for bright rooms and high-refresh gaming. The 42-inch S90F OLED is the contrast-focused alternative, while the QN90D is worth considering only at a compelling, well-warranted discount.
