LG C6 vs Samsung S90H: choose for the films and the room

LG C6 and Samsung S90H make a useful OLED comparison because the choice is not simply between a good screen and a bad one. LG's Dolby Vision support and Samsung's Glare Free treatment address different problems: how compatible HDR material is presented, and how the room intrudes on the picture. Start with what you watch and where the television will stand.

Both are 2026 product families. A buying decision still needs the exact size and regional model code. A review of a different diagonal or country variant cannot automatically settle the performance of the unit in your basket.

The window opposite the sofa belongs in the comparison

Samsung's Italian 65-inch S90H page lists Glare Free treatment. Samsung describes it as a way to reduce reflections. That makes it relevant to a bright living room, but the manufacturer's description is not a measurement of your particular window, lamps or seating arrangement.

A reflection that falls directly across a face can be more distracting than a small difference in peak brightness. Conversely, someone who mostly watches after dark may gain little from paying extra to solve a daytime problem. Compare a screen with dark content and the room lights on; a bright shop demonstration can conceal the reflection that bothers you at home.

LG's C6 specification page documents Dolby Vision and Filmmaker Mode. The latter is a useful starting point for avoiding an excessively processed presentation. A mode name does not guarantee perfect calibration, however, and no television can restore detail that the source never contained.

HDR support follows the content chain

LG documents Dolby Vision; Samsung's S90H lists HDR10+ Advanced and HDR10+ support instead. These formats use information about the content to guide its presentation. Compatibility matters only when the title, service or player actually supplies that format and the rest of the playback chain preserves it.

For a household with a substantial Dolby Vision library, LG therefore has a concrete compatibility argument. A Samsung buyer does not lose the ability to watch those films, but should not assume the television displays their Dolby Vision version. The available fallback depends on the source.

A 165Hz input is not a promise about a game

Both product pages advertise PC-oriented refresh capabilities reaching 165Hz. This describes what a compatible signal path can support, not the frame rate that a console or game will produce. Resolution, graphics settings, the source device and the game's own modes remain limiting factors.

For a console household, connection planning may be more valuable than the highest refresh number. Count the consoles, streaming box and other HDMI sources, then reserve the audio-return connection if a soundbar requires it. A television that fits the complete setup avoids the inconvenience and extra cost of switching cables or adding equipment.

The same discipline applies to a PC. Verify the chosen resolution and refresh mode, the graphics output and cable capability. Do not assume that every port, every format and every gaming feature operates simultaneously at the maximum printed in separate rows of a specification table.

Buy the local model, not an international headline

LG's Italian announcement and Samsung's Italian lineup announcement establish local ranges, but their launch promotions have dates. They are not October discounts. Compare the same screen size, the included stand or mounting arrangement, delivery and installation, and the exact local model code.

Also separate warranties by series: an offer attached to a flagship model is not automatically a benefit of the less expensive family. That matters more than choosing a brand on the strength of a feature belonging to another television.

If Dolby Vision is central to your viewing and reflections are manageable, C6 has the clearer feature fit. If a bright room repeatedly ruins dark scenes, S90H's reflection treatment deserves a close look. The best television purchase begins with the sofa, the window and the films you own—not the most spectacular loop playing in the shop.
