Which is better for a bright living room?

The Samsung S90H. Its Glare Free coating cuts reflections, while the LG C4 has a glossy finish that shows windows and lamps. If you can control the light, the C4's larger 65-inch picture wins.

Is the 42-inch Samsung worth more than the 65-inch LG?

Only if size is the constraint. At the November 4, 2026 prices the Samsung is $1,197.99 and the LG is $1,157.30, so you pay more for a much smaller screen. The Samsung's advantages are the anti-glare coating and higher gaming refresh.

Which is better for PS5 and Xbox Series X?

Both handle 4K at 120 Hz with VRR. The LG C4 has four HDMI 2.1 ports, which is easier with multiple consoles. The Samsung lists support up to 165 Hz with Motion Xcelerator and G-SYNC compatibility.

Does the LG C4 support Dolby Vision?

Yes. The C4 lists Dolby Vision, HDR10 and HLG. The Samsung S90H listing shows HDR10 and HLG but no Dolby Vision, so Dolby Vision discs and streams will fall back to HDR10 there.

Which has better built-in sound?

The Samsung S90H. It lists Dolby Atmos with Object Tracking Sound Lite. The LG C4 has Dolby Atmos but only two speakers, so a soundbar helps more on the LG.

Have either of these been cheaper recently?

Yes. The LG C4 hit $649.99 on November 1, 2026, and the Samsung S90H hit $849.00 on November 4, 2026, both well below their current best new prices. Check the price history before buying.
