Short answer

Choose LG for OLED and Dolby Vision: the C5 is the benchmark mid-range OLED, with Dolby Vision for streaming and Xbox and four 4K 120 Hz inputs. Choose Samsung for bright rooms and anti-glare screens: its Neo QLED (Mini LED) and Glare Free OLEDs handle windows best, and its lines run to 165 Hz. The biggest practical difference is HDR format: LG supports Dolby Vision but not HDR10+, Samsung HDR10+ but not Dolby Vision. Both put 4K 120 Hz on all four inputs in the lines we list, and neither includes an ATSC 3.0 tuner in them.

Key takeaways

  • OLED: LG C5 (WOLED, Dolby Vision) vs Samsung S90F/S90H (HDR10+, S90H with Glare Free and 165 Hz).
  • Mini LED: Samsung’s Neo QLED (QN90 series) is the stronger bright-room range in our catalogue.
  • HDR: Dolby Vision (LG) is more widely used by streaming services than HDR10+ (Samsung).
  • Smart TV: webOS (LG) vs Tizen (Samsung); both have AirPlay and ad-supported home screens.

LG and Samsung are the two largest TV brands, and they’ve taken different paths: LG built its range around OLED, while Samsung built its around quantum-dot LCD (QLED, then Mini LED as Neo QLED) and later added QD-OLED. Here’s how their current lines line up, from the spec sheets.

HDR format is the biggest everyday difference. Netflix, Disney+ and Apple TV+ stream many titles in Dolby Vision; fewer services use HDR10+. On a Samsung, Dolby Vision titles play in standard HDR10, which still looks good but drops the scene-by-scene metadata. See TVs with Dolby Vision.

Bright rooms favor Samsung: its Glare Free layer is the most widely used anti-reflection treatment in our catalogue. See the bright-room guide.

Antenna viewers should note neither brand’s current lines in our catalogue include an ATSC 3.0 tuner; Sony, Hisense and TCL have some (ATSC 3.0 TVs).

Our take

If you watch a lot of streamed films and series in the evening, or play Xbox with Dolby Vision, LG’s C5 is the better fit. If your room is bright, you want anti-glare, or you want a Mini LED with a polished smart platform, Samsung. Brand loyalty matters less than these two questions: OLED or Mini LED, and Dolby Vision or not.

Frequently asked questions

Which is better, LG or Samsung TV?

LG for OLED picture and Dolby Vision; Samsung for bright rooms, anti-glare screens and the widest Mini LED range. For gaming both are excellent, with all four inputs taking 4K 120 Hz in the lines we list.

Is LG OLED better than Samsung OLED?

They’re close. LG’s C5 supports Dolby Vision; Samsung’s S90H adds Glare Free anti-reflection and up to 165 Hz but uses HDR10+. In a bright room the S90H; for Dolby Vision streaming the C5.

Does Samsung support Dolby Vision?

No. Samsung TVs support HDR10+ instead. Dolby Vision content still plays, in HDR10.

Which lasts longer, LG or Samsung?

There’s no reliable public data by brand. Reliability depends more on the panel type and use (OLED burn-in, LCD backlight wear) than the badge.
