LG C6 vs. Samsung S90H: Which is the Best OLED TV of 2026?
We test the latest display technology to see which screen dominates your living room.
A Clash of Two Giants
Competition in the mid-range OLED market for 2026 has intensified significantly. LG’s new C6 model, a substantial upgrade over its predecessor, the C5, is considered a market leader. However, it faces a formidable rival in the Samsung S90H, which offers its own proprietary image processing technology and a distinct visual approach.
In terms of technical specifications, the Samsung S90H reached 1,689 nits in HDR Filmmaker mode, roughly 18% higher than the LG C6’s 1,427-nit output. Despite this, in real-world viewing conditions, the LG C6 delivers a brighter and more contrast-rich image. It appears that LG’s new Alpha 11 AI Gen 3 processor and the screen’s glossy coating handle light distribution more effectively than Samsung’s matte display.
Where Samsung Wins
While the LG C6 maintains more accurate colours and detail in dark, controlled environments, the Samsung S90H holds an undeniable advantage: its OLED Glare Free technology. If your TV is situated in a bright room where sunlight from windows causes reflections, the S90H is the clear winner. It effectively eliminates glare, maintaining visibility even in dark scenes where the C6 screen acts more like a mirror.
Regarding colour reproduction, both models perform at a high level, though they possess different 'personalities.' The LG C6 offers more saturated and vibrant colours, which is particularly evident in animated films. Conversely, the Samsung S90H maintains more natural tones, though it suffers from 'black crush' in some dark scenes, where shadow details are lost and blacks appear overly uniform.
Which Should You Choose?
Both televisions are available in sizes ranging from 42 to 83 inches and are excellent choices for gamers. As for pricing, the 55-inch models currently fall into a similar category, though market fluctuations may change this soon.
Ultimately, the choice depends on your living environment. If you are looking for a TV for a bright living room where sunlight frequently hits the screen, the Samsung S90H is the best choice. If you prioritise cinematic accuracy and colour depth, and primarily watch films in the evening in a dark room, the LG C6 is a much more balanced and consistent device. Both TVs meet the high standards of OLED technology, and neither will disappoint.
