The Samsung QN990F is a capable, bright 8K TV with strong upscaling and a distinctive Wireless One Connect box—but its picture and gaming compromises, format omissions, and high launch prices make it a niche buy. It makes the most sense if you specifically want a very large 8K screen and a cleaner cable setup. Most shoppers will get better value from a premium 4K TV.
What the Samsung QN990F offers
Samsung introduced the QN990F as its 2025 8K flagship in the Neo QLED range. It combines a Mini LED backlight with the NQ8 AI Gen3 processor, 8K AI Upscaling Pro, and Wireless One Connect, a separate box for most of the TV’s connections. Samsung lists the family in 65-, 75-, 85-, and 98-inch sizes in its 2025 U.S. launch announcement.
The separate connection box is the model’s clearest practical distinction: it can make it easier to place source devices and route cables without crowding the TV. The trade-off is important for gaming, however: independent testing found considerable input latency when devices connect through the wireless box. The TV’s own HDMI connection provides a better gaming experience when your installation allows you to use it.
Picture quality: bright and sharp, with visible trade-offs
Where it performs well
RTINGS bought and tested the 75-inch U.S. model, QN75QN990FFXZA. Its review finds the TV well suited to bright-room SDR and HDR viewing, with Mini LED local dimming that produces good black levels and limited blooming in the review’s reference conditions. The set also sharpens and upscales lower-resolution material effectively, a useful capability when native 8K content is scarce.

Where the image falls short
Brightness does not eliminate every picture issue. RTINGS reports that blacks can look raised in bright conditions, and that some blooming is visible. It also flags a noticeable dirty-screen effect, disappointing out-of-box accuracy, and severe color artifacts. These shortcomings matter if you want an even-looking screen or accurate color without adjustment.
Upscaling should not be mistaken for restoring detail that was never captured. The QN990F can improve apparent sharpness, but RTINGS also reports difficulty cleaning up artifacts in low-bitrate content. It notes judder in slow pans, blur behind fast-moving objects, and unwanted intermediate colors during transitions. That makes the set’s processing strength real, but not a guarantee that poor sources will look clean or motion will appear flawless.
Gaming: choose the connection path carefully
The QN990F supports VRR and ALLM. On the smaller models, RTINGS reports support for up to 8K at 120Hz or 4K at 240Hz. But these capabilities do not mean every setup will feel equally responsive: the wireless One Connect path adds considerable input latency, so connect a console or PC to the TV’s HDMI port when low latency matters and your room layout permits it.

The 98-inch version has a separate limitation: it is capped at 120Hz and does not offer the 4K-at-240Hz mode available on smaller sizes.
How the four sizes differ
RTINGS considers its 75-inch test results mostly applicable to the other sizes, but identifies two meaningful exceptions: the 65-inch model’s advertised HDR tier suggests somewhat lower brightness, while the 98-inch model is limited to 120Hz. The 98-inch model also has better speakers, according to RTINGS.
| U.S. size and model | Samsung launch price | Size-specific point |
|---|---|---|
| 65-inch QN65QN990FFXZA | $5,499 at 2025 U.S. launch | Different advertised HDR tier; RTINGS expects somewhat lower brightness. |
| 75-inch QN75QN990FFXZA | $6,499 at 2025 U.S. launch | Size purchased and tested by RTINGS. |
| 85-inch QN85QN990FFXZA | $8,499 at 2025 U.S. launch | RTINGS says 75-inch test findings mostly apply. |
| 98-inch QN98QN990FFXZA | $39,999 at 2025 U.S. launch | 120Hz ceiling, no 4K at 240Hz mode; better speakers per RTINGS. |

RTINGS says the QN990F does not support Dolby Vision or DTS audio. Samsung promotes HDR10+ in its launch materials, but that does not substitute for Dolby Vision when a streaming service or disc in your collection relies on that format. Likewise, if your home-theater system depends on DTS passthrough, confirm the source and audio chain before buying.
QN990F or QN900F?
RTINGS describes the QN990F and QN900F as similar in overall picture quality. The main distinction is the QN990F’s design and wireless input box; the QN900F keeps its inputs on the TV and is the better choice for low-latency gaming. If the wireless arrangement does not solve a real cable-placement problem for you, it may not justify choosing the QN990F over the similar-performing alternative.
Quick Recap
Who should buy the QN990F?
- Consider it if you want an unusually large, bright 8K TV, value the cleaner cable-placement options of Wireless One Connect, and accept the picture and format trade-offs.
- Look elsewhere if price is a priority, gaming latency through the One Connect box is unacceptable, or Dolby Vision or DTS support is essential to your viewing setup.
- Compare premium 4K TVs if you are shopping mainly for excellent picture quality rather than a large 8K screen. RTINGS notes that there is very little 8K content and concludes that most buyers are better off saving for a premium 4K TV.
