The LG G4 set the OLED reference for 2024-2025. Its second-generation MLA panel feeds the Alpha 11 processor for measurably brighter HDR than any prior consumer OLED, and all four HDMI 2.1 ports carry full support for serious gamers. Pair it with a soundbar and it becomes the easiest premium recommendation here.

Strengths
  • Second-gen Micro Lens Array panel pushes peak HDR highlights past 3,000 nits in metadata-rich content
  • Alpha 11 AI processor handles upscaling, motion, and tone-mapping with the best filmic processing in the OLED field
  • All four HDMI ports are full 48 Gbps HDMI 2.1 with 4K/144Hz, G-Sync, FreeSync Premium, and Dolby Vision gaming
Watch-outs
  • Built-in 4.2-channel audio is thin and lacks low-end weight — a soundbar is essentially mandatory at this price
  • OLED brightness still trails the brightest mini-LEDs in full-screen sustained windows
  • webOS 24 ads on the home screen are intrusive even after disabling personalized recommendations

Samsung's mid-tier QD-OLED is the value play for buyers who want OLED picture quality without paying flagship money. On certain content the QD-OLED panel renders saturated colors more vividly than the LG G4 does, and street pricing under $1,500 makes it the cheapest entry to true premium picture quality.

Strengths
  • Third-generation QD-OLED panel delivers wider color volume than competing WOLEDs, especially on saturated reds and greens
  • Roughly 1,300 nits peak HDR brightness on a 10% window — the brightest QD-OLED Samsung has shipped
  • All four HDMI ports are HDMI 2.1, with native 120Hz and a firmware-enabled 144Hz mode on HDMI 4 for PC use
Watch-outs
  • Samsung still refuses to support Dolby Vision — disc players and streaming services fall back to HDR10+
  • Standard matte coating (not the nano-textured S95D coating) shows brighter room reflections
  • Tizen home screen is ad-heavy and difficult to fully suppress

How they stack up

LG OLED evo G4 65-inch (OLED65G4SUB)

Outperforms the Samsung QN65S90D in motion handling and Dolby Vision support (Samsung still refuses to ship DV), and offers fundamentally better black levels than the TCL 65QM7K mini-LED for double the price. Against the Hisense 65U7N the G4 is roughly three times the cost but delivers OLED contrast that no mini-LED can match. The TCL 43Q651G is in a different category entirely — a small-room budget pick rather than a premium contender.

Samsung S90D 65-inch (QN65S90D)

Costs roughly $700 less than the LG OLED G4 at street, with comparable peak HDR brightness on smaller windows but without Dolby Vision support. Versus the TCL 65QM7K it is a different category — true OLED black levels at a price closer to flagship mini-LED than to flagship OLED. Against the Hisense 65U7N the Samsung is double the price but the per-pixel contrast and color volume justify the gap for serious movie watching.
