The Samsung S90F OLED is Samsung's refined mid-tier OLED offering for 2025. It uses a QD-OLED panel — Samsung's proprietary quantum dot OLED technology — which layers quantum dots over a blue OLED substrate for superior color volume compared to traditional white-OLED panels used by LG and Sony.

Buying Guide: What to Consider Before You Buy

Room Lighting Matters More Than You Think

OLED TVs like the Samsung S90F and LG C4 perform best in dim to moderate light environments where their perfect blacks can shine. In a bright sunlit room, consider the Samsung S95F with its Glare-Free coating, or a high-brightness Mini-LED set like the TCL QM8.

Gamers Need HDMI 2.1 Ports

If you're running a PS5, Xbox Series X, and a PC simultaneously, count the HDMI 2.1 ports carefully. The Samsung S90F leads the class with all four HDMI ports supporting 4K/144Hz — a significant advantage over the Sony Bravia 8 which only offers two.

Don't Ignore the Smart TV Platform

Tizen (Samsung), webOS (LG), and Google TV (Sony, TCL, Hisense) each have different strengths. Google TV offers the broadest app compatibility and Chromecast integration. Tizen is fast and clean with excellent gaming features. webOS is intuitive and well-designed, though it's becoming more ad-supported over time.

Size vs. Viewing Distance

For 4K content, a general rule is to sit no farther than 1.5x the screen diagonal. A 65-inch TV works best at around 8 feet; a 77-inch at about 10 feet. With aggressive discounts on the 77-inch Samsung S90F, going bigger than originally planned often makes financial sense right now.

Watch for Sales and Launch Discounts

Samsung regularly discounts the S90F significantly during promotional events. As noted in Samsung's latest OLED launch coverage, launch-period deals can bring the price down dramatically — making now an especially smart time to buy.

Frequently Asked Questions

Is the Samsung S90F better than the LG C4?

It depends on your priorities. The Samsung S90F produces brighter, more saturated colors thanks to its QD-OLED technology and offers more HDMI 2.1 ports for gaming. The LG C4 supports Dolby Vision — a format Samsung doesn't license — and often comes in at a slightly lower price point. Both are exceptional; choose Samsung for gaming and brightness, LG for movie accuracy and format support.

Should I worry about OLED burn-in?

For typical mixed-use viewing, burn-in risk on modern OLED panels is low. Samsung's QD-OLED panels in the S90F include pixel-shift and auto-dimming safeguards. Risk increases with prolonged static content — news tickers, HUD overlays in games — but for movies, streaming, and general TV watching, burn-in should not be a practical concern.

What's the difference between the Samsung S90F and S95F?

The S95F features a second-generation QD-OLED panel with higher peak brightness, a Glare-Free screen coating, and the external One Connect Box for cleaner cable routing. The S90F delivers comparable picture quality for most content at a meaningfully lower price — making it the better value for the majority of buyers.

Is a Mini-LED TV worth considering over the Samsung S90F?

If your room is very bright or you mainly watch sports and live content, a Mini-LED option like the TCL QM8 or Hisense U8N can outperform OLED panels in pure brightness. However, for dark room cinematic viewing and gaming, the Samsung S90F's infinite contrast and color volume make it the superior choice.
