When new TVs are released, old TVs go on sale. At the time of publishing, the brands behind some of the best OLED TVs are launching all-new OLEDs to replace last year's models. This means that you can get last year's stuff at a huge discount, and in many cases, those year-old sets are almost as good as their replacement models.
The LG C6 OLED is LG's newest, mid-range OLED for 2026. The Samsung S90F OLED is Samsung's mid-range model from 2025. They're direct competitors, at least they would be if there wasn't a year separating them. Nevertheless, they occupy the same shelf space right now, which means you've got a choice between the two. Here's how these OLEDs stack up and what you should know before shopping.
See how the LG C6 and Samsung S90F stack up side by side

Note: The C6 is available in 77- and 83-inch versions, but these sizes are classified as an altogether different model: the LG C6H. If you want a 77- or 83-inch C6, you'll technically have to buy the C6H.
As the brand's newest mid-range OLED TV, the LG C6 delivers an excellent blend of performance and value. It's an incremental upgrade from previous models and performs similarly to the Samsung S90F. However, as a 2026 model, it's much pricier than the S90F.
LG promises better performance on these sets as they're equipped with LG Display's newest RGB Tandem OLED. The 42- to 65-inch versions of the C6, on the other hand, use a standard WOLED display.
The C6 follows the design approach of its predecessor, the LG C5. Its downward-slanting, wedge-shaped stand attaches itself to the TV's chassis, and the shape of the stand keeps the C6's screen relatively close to its surface. All told, it's a sleek look. And, while you'll almost never see this design flourish, the marble-like finish on the back of the panel is a nice touch.
The C6 arrives with the newest version of LG's Magic Remote. Like its motion-activated forerunners, this clicker can be used to point and click at the screen, though it also comes with a traditional directional pad.
The Samsung S90F delivers sensational, mid-range OLED performance thanks to bright highlights and excellent color volume. It's also packed with gaming features. Best of all? It's much more affordable than the 2026 C6.
One of the biggest differences between these sets lies in HDR support. Like all LG OLEDs, the C6 supports Dolby Vision. No Samsung TV currently supports Dolby Vision. Instead, Samsung offers HDR10+ across all of its HDR-enabled TVs. HDR10+ is a royalty-free version of Dolby Vision that similarly uses metadata to adjust the picture on a frame-by-frame basis.
The S90F uses a pedestal-style stand that lifts the panel further up from its surface. The clearance might be nice if you own a particularly bulky soundbar. Most of the S90F's internal hardware is relegated to a rectangular-shaped chassis that bulges out from the bottom half of the panel.
Perhaps the S90F's best feature is the included Samsung Solar Cell remote. It's a slim, narrow clicker with a minimal amount of buttons. Frustratingly, it doesn't include a dedicated input button. Refreshingly, it's powered by a rechargeable lithium-ion battery, which powers itself up with natural and artificial light.
The good news is that both sets serve up four HDMI 2.1-compatible inputs and support 4K gaming at 120Hz. With a PC linked up to either OLED, 4K games can be pushed up to 165Hz on the C6 and 144Hz on the S90F.
Neither offers ATSC 3.0 support, which allows over-the-air broadcasts to be piped in at native 4K resolution. These sorts of broadcasts are still few and far between, but for folks who really lean on the terrestrial airwaves, ATSC 3.0's absence is a disappointment.
While the C6 features a more thoughtful-looking design, the S90F offers better soundbar clearance and a rechargeable remote. This one's too close to call.
