LG 4K HDR Smart OLED TV vs TCL QM7K 98-Inch QD-Mini LED TV

Buy the LG OLED if you want the best contrast and viewing angles in a normal-sized room, and you mostly watch movies, streaming shows and sports in a dim or mixed-light room. Buy the TCL QM7K if you sit far back and want a wall-filling 98-inch picture with very high brightness for a bright room, plus 144Hz gaming. The LG wins on per-pixel contrast, thin build and off-angle viewing; the TCL wins on size, peak brightness and motion for games. Owners rate the TCL slightly higher, but on far fewer ratings, and OLED owners consistently praise black levels and design.

  • Choose the LG OLED if you want deep blacks, wide viewing angles and a slim panel for a typical living room or bedroom.
  • Choose the TCL QM7K if you have a large wall, sit well back, and want a huge bright picture with fast gaming features.

What reviewers say

LG 4K HDR Smart OLED TV

  • 4.6 / 51,600 ratings

Owners rate it highly, with 4.6 out of 5 across 1,600 ratings. Praise centers on picture quality, especially blacks and contrast, and on the built-in smart features. Complaints are mostly about brightness in bright rooms and the premium over LED sets.

What people mention
  • Picture qualityPraisedOwners single out the deep blacks and contrast as the reason to buy OLED.
  • BrightnessCriticisedSome say the panel struggles in bright, sunlit rooms compared with LED sets.
  • Viewing anglesPraisedThe picture holds up from the side, which suits wide seating.
  • Smart featuresPraisedBuilt-in Google Assistant and Alexa are seen as useful and easy to set up.

TCL QM7K 98-Inch QD-Mini LED TV

  • 4.8 / 5486 ratings

Owners rate the QM7K very highly, praising its brightness, contrast and size for the money. Most criticism centers on the set's bulk and setup rather than picture quality.

What people mention
  • Picture brightnessPraisedOwners say HDR highlights pop and the screen holds up in bright rooms.
  • Black levelsMixedReviewers report deep blacks overall but some blooming around bright objects.
  • GamingPraisedOwners like the high refresh rate and low input lag for consoles.
  • SoundMixedThe Bang & Olufsen tuning is fine for everyday TV but short of a soundbar.

Questions and answers

Which is better for a bright living room?
The TCL QM7K. Its Mini-LED backlight reaches far higher brightness, so it holds up against daylight and reflections. The LG OLED looks best in controlled light.
Which has better picture quality for movies?
The LG OLED for dark-room movies, because per-pixel lighting gives true blacks and no blooming. The TCL is brighter and bigger, which many people prefer for a dedicated theater wall.
Which is better for gaming?
The TCL QM7K. It has a 144Hz native panel, Game Accelerator up to 288Hz, ALLM and low input lag. LG OLEDs game well too, but this TCL is built around fast motion.
Is the TCL too big for a normal room?
At 98 inches it needs a large wall and a viewing distance of roughly 9 to 12 feet to feel comfortable. Measure the wall and the walkway before committing.
Which lasts longer?
Both should run for years. OLED can develop image retention from static logos or tickers over long sessions, while the TCL's LCD panel has no burn-in risk but relies on a backlight that dims over time.
Is the LG worth stepping up to over the TCL?
Step up to the LG if contrast, viewing angles and a slim design matter more than size and brightness. Stay with the TCL if you want the biggest, brightest picture for the room.
