Comparia recommendation
Best TV for Xbox Series X
The LG OLED55C3 is the best TV for Xbox Series X because it delivers the lowest input lag, exclusive Dolby Vision gaming support, four full HDMI 2.1 ports and the most responsive Game Optimiser mode available.
Why the LG OLED55C3 is the best TV for Xbox Series X
Comparia analysed four leading TVs across five evaluation criteria: input lag, HDMI 2.1 features, HDR gaming, picture quality and value for money. Each criterion was weighted based on how Xbox Series X gamers prioritise their TV purchase, with input lag and HDMI 2.1 features rated as critical factors.
The LG OLED55C3 leads because it is the only TV that supports Dolby Vision gaming, an exclusive feature available only on Xbox Series X paired with LG OLED displays. This combination delivers dynamic HDR metadata that adjusts frame by frame during gameplay, producing richer highlights and deeper shadows in supported titles like Halo Infinite, Forza Horizon 5 and Call of Duty. The C3 also achieves approximately 9ms of input lag at 4K 120Hz, which is among the lowest measured on any consumer television. Its four full HDMI 2.1 ports mean you never need to swap cables between your Xbox, soundbar and other devices.
The Samsung S90C came close with brighter HDR highlights and excellent VRR performance, but lacks Dolby Vision gaming entirely. The Sony X90L offers superior upscaling for older Xbox titles through Auto HDR but trails in input lag. The Hisense U8K delivers remarkable value at roughly half the price but cannot match OLED response times or contrast.
Decision confidence: 92%
High confidence because
- Only TV that supports Dolby Vision gaming with Xbox Series X
- Lowest input lag at ~9ms with all four HDMI 2.1 ports active
- Xbox certified with dedicated Game Optimiser mode and VRR/ALLM
Confidence reduced because
- Samsung S90C is brighter for HDR gaming in well-lit rooms
- Hisense U8K offers similar gaming features at roughly half the price
Best TV for every Xbox gaming priority
Why the LG OLED55C3 wins for Xbox Series X
-
Exclusive Dolby Vision gaming
The Xbox Series X is the only console that outputs Dolby Vision for gaming, and LG OLED TVs are the only displays that can receive this signal. This pairing delivers frame-by-frame dynamic HDR metadata during gameplay, producing visibly richer highlights in bright skies and deeper detail in dark environments. In titles like Forza Horizon 5, the difference between Dolby Vision gaming and standard HDR10 is immediately apparent in sunset scenes and tunnel transitions.
-
~9ms input lag at 4K 120Hz
The C3 achieves approximately 9ms of input lag with Game Optimiser enabled at 4K 120Hz. This is among the fastest response times available on any consumer television. In competitive multiplayer titles like Halo Infinite and Call of Duty, the difference between 9ms and 15 to 20ms can mean the difference between landing a shot and missing it. The near-instant pixel response of OLED eliminates motion blur during fast camera pans.
-
Four full HDMI 2.1 ports
Every HDMI port on the C3 supports the full HDMI 2.1 specification including 4K at 120Hz, VRR, ALLM and eARC. This means you can connect your Xbox Series X, a soundbar and additional devices without compromising on bandwidth. The Samsung S90C offers four HDMI ports but only two support full 4K 120Hz, while the Hisense U8K has just two HDMI 2.1 ports.
-
VRR and ALLM support
Variable Refresh Rate eliminates screen tearing when the Xbox's frame rate fluctuates, which is common in demanding open-world titles. ALLM automatically switches the TV to its lowest latency game mode when you launch a game and reverts to cinematic processing when you open a streaming app or Blu-ray. Quick Resume on Xbox works seamlessly with these features, maintaining the correct display mode as you switch between suspended games.
-
Dedicated Game Optimiser mode
LG's Game Optimiser provides a centralised dashboard for all gaming settings. You can adjust black stabiliser for visibility in dark scenes, toggle VRR, switch between genre presets (FPS, RPG, RTS) and monitor real-time input lag and frame rate. The interface is accessible via a single button press during gameplay without leaving the game.
Trade-offs to consider
-
Samsung S90C is brighter for HDR
The S90C reaches approximately 1300 nits compared to the C3's 800 nits. If you game during the day in a bright room, the Samsung's HDR highlights will be more visible and impactful.
-
Hisense U8K is much cheaper
At approximately £549, the Hisense U8K costs roughly half the price of the LG C3. It still offers HDMI 2.1, 4K 120Hz and VRR. For casual gamers, the value proposition is hard to ignore.
-
Sony X90L has better upscaling
If you play a lot of older Xbox One or Xbox 360 back-compatible titles, the Sony's XR Cognitive Processor does a noticeably better job of upscaling lower-resolution content to 4K.
Best alternative: Samsung S90C
The Samsung S90C uses QD-OLED technology, combining OLED-level contrast with significantly higher peak brightness and a wider colour gamut. It is an excellent Xbox Series X TV for bright rooms.
Choose Samsung S90C if
- · You game in a bright living room during the day
- · You want the most vivid HDR highlights in games
- · You do not prioritise Dolby Vision gaming
Choose LG OLED55C3 if
- · Dolby Vision gaming is important to you
- · You want the absolute lowest input lag
- · You need four full HDMI 2.1 ports
What would change this recommendation
If you game in a very bright room
Samsung S90C becomes the better choice. Its ~1300 nit peak brightness makes HDR gaming visible even with direct sunlight.
If budget is the primary constraint
Hisense U8K at ~£549 delivers 4K 120Hz, VRR and low input lag at roughly half the price of OLED.
If you play mostly older back-compat titles
Sony X90L's XR Cognitive Processor produces the best upscaling of Xbox One and Xbox 360 games running via backwards compatibility.
If you worry about OLED burn-in
Hisense U8K or Sony X90L eliminate any burn-in concern. Both use LED backlighting with no risk from static HUD elements.

Detailed analysis
Input lag
Input lag is the most heavily weighted criterion because it directly determines how responsive a game feels. The delay between pressing a button on your controller and seeing the result on screen is the single most important factor for competitive and action-oriented gaming.
The LG OLED55C3 scores 10/10. With Game Optimiser enabled, it achieves approximately 9ms of input lag at 4K 120Hz. This is among the lowest figures measured on any consumer television. The near-instant pixel response time of OLED technology means there is virtually zero motion blur during fast camera movements, which is critical in first-person shooters like Halo Infinite and Call of Duty.
The Samsung S90C scores 9/10 with approximately 10ms of input lag at 4K 120Hz. The difference of 1ms is imperceptible to most players, but the Samsung's slightly higher processing overhead at 4K 120Hz with VRR active occasionally introduces micro-stuttering that the LG avoids.
The Sony X90L scores 7/10 with approximately 15ms of input lag. This is still good for casual gaming but noticeable in fast-paced competitive titles. The Hisense U8K scores 7/10 with approximately 13ms, which is impressive for its price point but trails the OLED options.
HDMI 2.1 features
HDMI 2.1 is rated critical because the Xbox Series X requires it to output 4K at 120Hz, VRR, ALLM and Dolby Vision gaming. Without full HDMI 2.1 support, the console cannot use its most advanced display features.
The LG OLED55C3 scores 10/10. All four HDMI ports support the complete HDMI 2.1 specification at 48Gbps bandwidth. This means every port can handle 4K at 120Hz with VRR and ALLM simultaneously. It is also the only TV in this comparison that supports Dolby Vision gaming, an Xbox-exclusive feature that delivers dynamic HDR during gameplay.
The Samsung S90C scores 8/10. It has four HDMI ports but only two support full 4K at 120Hz bandwidth. It supports VRR and ALLM but lacks Dolby Vision gaming entirely, as Samsung does not licence Dolby Vision on any of its televisions.
The Sony X90L scores 7/10. Two of its four HDMI ports support 4K at 120Hz. It supports VRR and ALLM but, like Samsung, does not support Dolby Vision gaming output from the Xbox. The Hisense U8K scores 7/10 with two HDMI 2.1 ports, VRR and ALLM support, and no Dolby Vision gaming.
HDR gaming
HDR gaming is rated important because the Xbox Series X supports multiple HDR formats including HDR10, Dolby Vision and Auto HDR, which retroactively applies HDR to hundreds of older titles. The quality of a TV's HDR processing affects every game that supports it.
The LG OLED55C3 and Samsung S90C both score 9/10 for HDR gaming but for different reasons. The LG excels with Dolby Vision gaming, delivering frame-by-frame dynamic metadata in supported titles. The Samsung excels in raw brightness, pushing HDR highlights to approximately 1300 nits. In games with bright explosions, sunlit landscapes and neon lighting, the Samsung's highlights are more impactful. However, the LG's infinite contrast means dark areas in HDR content retain more detail.
The Sony X90L scores 8/10. Its HDR tone mapping is well calibrated for gaming and its Auto HDR implementation looks natural on older back-compatible titles. The Hisense U8K scores 7/10 with strong brightness for its price but less refined HDR tone mapping in fast-moving game content.
Picture quality
The LG OLED55C3 scores 9/10 for picture quality during gaming. Its WOLED panel produces perfect blacks and infinite contrast, which creates a genuinely immersive experience in atmospheric games. Colour accuracy is excellent with 98.5% DCI-P3 coverage, and the near-instant pixel response eliminates ghosting during fast motion.
The Samsung S90C also scores 9/10. QD-OLED technology produces a wider colour gamut than standard WOLED, with particularly vibrant reds and greens. Games with vivid art styles benefit from the Samsung's colour volume advantage. However, Samsung's processing tends toward a more saturated, punchy look rather than the neutral accuracy that LG achieves.
The Sony X90L scores 8/10. Its Full Array LED backlight with local dimming produces good contrast but cannot match the per-pixel control of OLED. Its strength is upscaling, with the XR Cognitive Processor doing an exceptional job with Xbox One and Xbox 360 back-compatible titles. The Hisense U8K scores 7/10 with a Mini-LED backlight that produces strong brightness and decent local dimming but visible blooming around bright objects in dark scenes.
Value
At approximately £1099, the LG OLED55C3 scores 7/10 for value. It is the most expensive option but delivers the strongest gaming feature set including exclusive Dolby Vision gaming support. The Samsung S90C at approximately £999 scores 8/10, offering QD-OLED picture quality and excellent gaming performance at a lower price. The Sony X90L at approximately £849 scores 8/10 with solid gaming features and the best upscaling. The Hisense U8K at approximately £549 scores 9/10 for value, delivering 4K 120Hz, VRR and ALLM at roughly half the price of OLED, making it the clear budget champion for Xbox gaming.
