LG C4 77-inch OLED evo 4K Smart TV vs TCL QM7K 98-Inch QD-Mini LED TV

Buy the LG C4 if picture quality per inch matters most: per-pixel OLED contrast, near-instant pixel response and four HDMI 2.1 ports make it the better film and console gaming set. Buy the TCL QM7K if you sit far back in a bright room and want sheer size: 98 inches of Mini-LED with very high peak brightness and a 144Hz panel. Reviewers and owners praise the C4's blacks, viewing angles and gaming features; the QM7K draws praise for brightness and size, with some complaints about uniformity and upscaling of low-quality sources.

  • Choose the LG C4 if you want the deepest blacks, wide viewing angles and the cleanest motion for movies and console gaming in a normal-sized room.
  • Choose the TCL QM7K if you have a large wall, sit well back and watch in a bright room where a huge, very bright Mini-LED screen wins.

What reviewers say

LG C4 77-inch OLED evo 4K Smart TV

Reviewers consistently praise the C4 for its contrast, gaming features and improved brightness over earlier C-series models. Owners like the picture and the four HDMI 2.1 ports, while some note reflections in bright rooms and worry about burn-in over time.

What people mention
  • Picture qualityPraisedOwners and reviewers call the contrast and color excellent, especially in darker rooms.
  • GamingPraisedThe 120 Hz panel, VRR and four HDMI 2.1 ports are singled out as a strong package for consoles and PCs.
  • BrightnessMixedThe evo panel is brighter than earlier C-series sets, but reviewers say it still trails the brightest LED TVs in a sunlit room.
  • ReflectionsCriticisedThe screen lacks an anti-glare coating, so lamps and windows show up in bright viewing spaces.

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.

Questions and answers

Which is better for console gaming?
Both are strong. The LG C4 has four HDMI 2.1 ports, near-instant pixel response and G-Sync certification, which suits PS5 and Xbox Series X. The TCL QM7K runs 144Hz with Game Accelerator up to 288Hz and ALLM, so it is the pick for high-frame-rate PC gaming on a huge screen.
Which handles a bright room better?
The TCL QM7K. Its Mini-LED backlight reaches far higher peak brightness and its anti-reflective panel fights glare. The LG C4 wins in dark rooms, where OLED contrast shows.
Is the TCL worth stepping up to for the size?
If your seating distance is far enough that 77 inches feels small, yes. At close range a 98-inch screen can feel overwhelming, and the C4's per-pixel contrast is the better picture at normal distances.
Which lasts longer?
LED backlights like the QM7K's do not suffer burn-in, so they are safer for static content such as news tickers or game HUDs. OLED panels can retain static images over long periods, though the C4's pixel refresh routines reduce the risk.
Which has better sound without a soundbar?
The TCL QM7K. Its Bang & Olufsen-tuned system with Dolby Atmos, DTS Virtual:X and IMAX Enhanced certification is more capable than the LG C4's built-in speakers. Either benefits from a soundbar.
Does the LG C4 support Dolby Vision and HDR10+?
It supports Dolby Vision and HDR10 but not HDR10+. The TCL QM7K supports Dolby Vision, HDR10+ and HLG, so it covers more HDR sources.
