LG C5
Owners rate the C5 highly, at 4.8 out of 5 from about 18,000 ratings, with most praise going to picture quality and gaming features. The main complaint is brightness and color punch next to brighter OLED competitors.
- Deep blacks and strong contrast for films
- Smooth 144Hz gaming with low lag
- Simple webOS interface and plenty of free channels
- Slim design and narrow bezel
- Peak brightness trails some rival OLEDs
- Color volume is not as rich as QD-OLED sets
- Glare in bright rooms
- Burn-in worries for heavy news or sports viewing
Samsung 55" Class S90H OLED 4K Smart TV (2026)

Questions and answers
- Which is better for gaming?
- The S90H has the higher refresh rate at 165Hz versus 144Hz on the C5. Both have four HDMI 2.1 ports and VRR, so either works well with a PS5 or Xbox.
- Which has better picture quality?
- Both are OLED panels with near-infinite contrast. The C5 adds Dolby Vision, while the S90H adds a Glare Free coating that holds up better in rooms with windows.
- Is the S90H worth the extra money?
- It costs $258 more at best new price on November 3, 2026. That buys the Glare Free coating, a 165Hz panel and Wi-Fi 6E. If your room is dark and you do not need those, the C5 saves money.
- Which is better in a bright room?
- The S90H, because of its Glare Free coating. The C5 has anti-glare treatment but reviewers note it is not as bright as some competing OLEDs.
- Which lasts longer?
- Neither maker publishes a lifespan figure for these models. Both are OLED panels, so burn-in risk depends more on what you watch than on the brand.
- Should I wait for a lower price on the C5?
- It hit $781.60 on November 2, 2026, well below the $939.95 best new price on November 3. If you are not in a hurry, set a price alert.
