Ranked #1 in Best 4K TVs

LG OLED evo G4 65-inch (OLED65G4SUB)

4.5

3 sources$1,998as of Jul 3

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

— 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
— Gallery-flush wall mount design ships in the box with virtually no gap when wall-mounted

Watch-outs

— Built-in 4.2-channel audio is thin and lacks low-end weight — a soundbar is essentially mandatory at this price

Ranked #2 in Best 4K TVs

Samsung S90D 65-inch (QN65S90D)

4.5

2 sources$1,149as of Aug 16

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

— All four HDMI ports are HDMI 2.1, with native 120Hz and a firmware-enabled 144Hz mode on HDMI 4 for PC use
— Tizen smart OS is fast and responsive, with deeper game-streaming integration than Google TV
— Frequently discounted below $1,500 — the cheapest premium OLED experience on the market

Watch-outs

— Samsung still refuses to support Dolby Vision — disc players and streaming services fall back to HDR10+
