Samsung S90H OLED 4K Smart TV vs LG C5 OLED evo TV

Both are 4K OLED TVs with 144Hz-class panels and HDMI 2.1, so picture fundamentals are close. The Samsung S90H adds a Glare Free coating, four HDMI 2.1 ports and a 165Hz panel, which suits bright living rooms and serious gamers. The LG C5 evo has the more mature webOS platform and a long track record, but owners report more software bugs and a divisive remote. Pick the Samsung for a window-lit room or a console setup; pick the LG if you want the platform and ecosystem you already know.

  • Choose the Samsung S90H if your room has windows or overhead lights, or if you need four HDMI 2.1 inputs for a console plus a soundbar and a PC.
  • Choose the LG C5 evo if you want webOS and its app selection, or you are replacing an older LG and want the same remote and menus.

What reviewers say

Samsung S90H OLED 4K Smart TV

  • 4.9 / 5348 ratings

Buyers rate the S90H very highly, at 4.9 out of 5 from 348 ratings. Praise centers on the OLED picture and the glare handling; the main reservations are brightness in very bright rooms and price.

What people mention
  • Picture qualityPraisedOwners call the blacks and contrast the reason to buy an OLED.
  • GlarePraisedThe Glare Free coating is singled out for handling windows and overhead lights.
  • BrightnessMixedFine in most rooms, but some find it dimmer than expected in very bright spaces.
  • GamingPraisedHigh refresh and HDMI 2.1 ports get credit for smooth console play.

LG C5 OLED evo TV

  • 4.9 / 5852 ratings

Owners and reviewers rate the C5 among the best TVs for the money, praising its crisp, vivid and bright picture, gaming features and ease of use. Complaints center on software bugs, a poorly designed remote and the usual OLED cautions about static content.

What people mention
  • Picture qualityPraisedOwners call the contrast and color accuracy the best part of the set, describing the picture as crisp, vivid and bright.
  • BrightnessMixedFine for most rooms, but reviewers say it dims next to the G5 in daylight.
  • GamingPraisedFour HDMI 2.1 ports and 144Hz support are repeatedly singled out.
  • Burn-inCriticised

Questions and answers

Which is better for a bright living room?
The Samsung S90H. Its Glare Free coating cuts reflections far better than the LG C5's glossy finish, so windows and lamps are less of a problem during the day.
Which is better for gaming?
They are close. Both offer four HDMI 2.1 ports, VRR and low latency. The Samsung's 165Hz panel gives a little more headroom on PC, while the LG's 0.1ms response and ClearMR 9000 rating keep motion clean.
Which lasts longer?
Neither has a clear edge on panel life; both use OLED and both carry similar warranties. The LG has a longer field record, but owners report more software glitches, while the Samsung's record is shorter because it is newer.
Is the LG worth stepping up to over the Samsung?
Only if you want webOS or the LG remote. The Samsung matches or beats it on glare handling, refresh rate and wireless, and adds Alexa and Google Assistant.
Do either support Dolby Vision?
The LG C5 supports Dolby Vision. Samsung does not support Dolby Vision on any of its TVs, including the S90H, so HDR10 content is the ceiling there.
Which has better sound out of the box?
The Samsung. Its 40W 2.1ch system with Object Tracking Sound Lite fills a room better than the LG's built-in speakers, though a soundbar improves both.
