Samsung S90HD OLED 4K Smart TV vs LG B6 OLED evo 4K Smart TV

Both are 65-inch 4K OLEDs with 120Hz panels, so picture quality is close. The Samsung S90HD edges ahead on gaming features, glare handling and sound, with a glare-free coating, Motion Xcelerator up to 165Hz, FreeSync Premium Pro and G-SYNC support, and Object Tracking Sound Lite with Dolby Atmos. The LG B6 uses an Alpha 8 Gen3 processor and adds Dolby Vision, which the Samsung listing does not mention, and it is far lighter at 17.1 lb without the stand versus 75.4 lb for the Samsung. Buy the Samsung for a bright room or serious gaming; buy the LG for Dolby Vision content and easier wall mounting.

  • Choose the Samsung S90HD if you game on a console or PC, watch in a room with windows or lamps, and want stronger built-in sound.
  • Choose the LG B6 if you want Dolby Vision support and a much lighter set that is simpler to wall mount.

What reviewers say

Samsung S90HD OLED 4K Smart TV

  • 4.8 / 5222 ratings

Rated 4.8 out of 5 from 222 ratings, the S90HD is well received. Owners single out the glare-free screen and gaming features; the main complaints are brightness and OLED care dimming.

What people mention
  • GlarePraisedOwners say the Glare Free screen keeps reflections down in bright rooms.
  • Picture qualityPraisedDeep blacks and strong contrast are the most common compliments.
  • GamingPraisedHigh refresh rate and VRR support are called out by console and PC players.
  • BrightnessMixedSome find it bright enough, others want more punch in daylight.

Questions and answers

Which is better for gaming?
The Samsung. It lists Motion Xcelerator 165Hz, G-SYNC and FreeSync Premium Pro, while the LG lists VRR up to 144Hz. Both run 120Hz natively, so the gap is small but real for high-frame-rate PC play.
Does the LG have Dolby Vision and the Samsung not?
The LG B6 lists Dolby Vision, HDR10 and HLG. The Samsung S90HD lists OLED HDR+ but no Dolby Vision. If you watch a lot of Dolby Vision movies, the LG is the safer pick.
Which handles a bright room better?
The Samsung, because of its Glare Free coating that reduces reflections. The LG specs do not mention an anti-glare layer.
Which is easier to wall mount?
The LG. It weighs 17.1 lb without the stand and uses a 300 x 200 VESA pattern. The Samsung is 75.4 lb, so it needs a heavier-duty mount and a second pair of hands.
Is the Samsung worth stepping up to over the LG?
If you game or have a bright room, yes, for the glare-free screen, higher refresh ceiling and better sound. If you mainly watch movies and want Dolby Vision, the LG covers you and is lighter.
Do either need a soundbar?
The Samsung's Object Tracking Sound Lite and Dolby Atmos give it more headroom. The LG's 20W 2.0-channel system is basic, so a soundbar helps more there.
