Samsung S90H 48-inch OLED as a desk TV: what the testing says
Buy the S90H if a window or overhead lights hit your screen. Its matte Glare Free coating is the Samsung's biggest advantage over the LG C6, as RTINGS puts it in naming the 42-inch S90H the C6's alternative for PC use, and the 48-inch adds 165Hz on all four HDMI ports, FreeSync Premium Pro, and 40W 2.1-channel speakers. RTINGS says the 48-inch uses an RGB tandem panel, but no outlet has reviewed that size yet; the matte screen lifts blacks slightly in a lit room, and there's no Dolby Vision.
Our take
The short version
Most desk TVs are glossy, which is fine in a dim room and a problem with a window behind you. Samsung's 2026 S90H is the exception: Samsung says its Glare Free coating is certified at 15 gloss units or less (a mirror is 100), and RTINGS says it does an amazing job handling glare. In RTINGS' guide to the best TVs for PC use, the 42-inch S90H is the alternative to the LG C6, with the matte coating as its biggest advantage for bright rooms; RTINGS adds that the LG is a bit brighter and more versatile thanks to its image processing.
We picked the 48-inch because Amazon sells it directly; on October 7 the 42-inch S90H was only available from a third-party seller with one unit left. At 48 inches, Samsung lists 165Hz on all four HDMI ports, FreeSync Premium Pro and G-Sync support, and 40W 2.1-channel speakers, the most capable sound in this lineup on paper. RTINGS says the 48- and 77-inch S90H use an RGB tandem panel, which its 77-inch review says is advertised as brighter and more colorful than the other sizes. No outlet has published a review of the 48-inch itself yet, so treat its brightness as promising rather than proven.
The trade-offs: matte coatings lift blacks a little. Tom's Guide (testing the 55-inch) noticed slightly raised black levels as the trade for handling window light, and CNET (65-inch) found on-screen black very slightly gray in a lit room. There's HDR10+ but no Dolby Vision, RTINGS notes an aggressive brightness limiter in very bright scenes, and text at 48 inches has the same 92-pixel-per-inch softness as any 48-inch 4K screen. It launched at $1,599.99 and was $1,097.99 from Amazon on October 7.
Setup
At your desk
- ~92 PPI
- 4
- 165Hz
- 300 x 200 mm
- Best for: desks that face a window or sit under bright office lights, where a glossy OLED would mirror the room.
- Stand: a center pedestal 14.4 inches wide but 10.4 inches deep, the deepest stand here. Measure your desk, or wall-mount it.
- Mounting: VESA 300 x 200 at 23.4 lb without the stand, the lightest 48-inch here, so a heavy-duty arm or a wall mount is realistic.
- Burn-in: Samsung's Panel Care includes pixel shift, logo brightness adjustment, and pixel refresh. Samsung's one-year warranty doesn't say whether burn-in is covered.
Pixel density is plain geometry for a 4K screen at the class size, not a measurement.

- RGB tandem panel at 48 inches, per RTINGS
- 40W 2.1-channel speakers, the most in this lineup

Who it's for
Buy it if…
- Desks facing a window or under bright overhead lights
- PC gamers who want 165Hz and FreeSync Premium Pro at 48 inches
- Anyone who prefers Samsung's Tizen and Gaming Hub
Skip it if…
- Dark-room gamers: the glossy LG C6 48 keeps blacks deeper and adds Dolby Vision

- Dolby Vision fans, for films or Xbox games
