Which is better for a bright living room?

The Samsung S90H. Its Glare Free coating cuts reflections from windows and lamps better than the LG C5's glossy anti-glare panel. The C5 is brighter in highlights, but reflections are more visible.

Which is better for PS5 and PC gaming?

The LG C5. It has four HDMI 2.1 ports, 0.1ms response time and VRR up to 144Hz for PC. The Samsung runs 120Hz with its Ultimate Gaming Pack, which is fine for consoles but caps PC play at 120Hz.

Is the Samsung worth the extra money?

Only if reflections are your main problem. The LG costs $950.74 at eBay versus $1,399.99 at The Home Depot for the Samsung as of November 4, 2026, and adds Dolby Vision and Atmos.

Which has better HDR?

The LG C5 for streaming. Dolby Vision is used by Netflix, Disney+ and most 4K Blu-rays. The Samsung supports HDR10+ instead, which fewer services use.

Both are OLED and carry similar burn-in risk. The LG has a longer track record of OLED panels, and its 4.2 rating from 273 owners is lower than the Samsung's 4.8 from 224, so owner reports favor the Samsung slightly.

Do both support voice assistants?

The LG C5 lists Google Assistant and Amazon Alexa support. The Samsung S90H uses Samsung's Bixby and Alexa built in, but not Google Assistant.
