Which is better for a bright living room?

The Samsung S90H. Its Glare Free coating reduces reflections, while the LG C4 has no anti-glare treatment. In a room with windows or overhead lights, the S90H holds contrast better during the day.

Which is better for gaming?

The S90H on paper: it supports gaming up to 165 Hz with Motion Xcelerator, VRR and low latency. The C4 runs 120 Hz with VRR and G-Sync certification, which is enough for most consoles and PCs.

Is the S90H worth the extra $14?

At $1,197.99 at Best Buy versus $1,183.91 for the C4 at Best Buy as of November 4, 2026, yes if glare is a problem in your room. If you watch in the dark, the C4 saves money and matches it on contrast.

Neither has a published lifespan figure. The C4 carries a 5-year webOS update commitment through the Re:New program, which keeps its apps current longer. OLED burn-in is a risk on both; one C4 owner reported it.

Do both have four HDMI ports?

Yes. Both list four HDMI ports with CEC support, enough for a console, a soundbar and two streaming devices.

Which has better sound built in?

The S90H lists Dolby Atmos and Object Tracking Sound Lite. The C4's listing gives no comparable audio features, so a soundbar is the safer bet with either.
