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 #4 in Best 4K TVs

TCL 65QM7K QD-Mini-LED 65-inch

4.2

3 sources$749.99as of Jul 3

TCL's 2025 mid-range QD-mini-LED is the price-performance king of this guide. Measured peak HDR brightness lands in the same neighborhood as premium mini-LEDs at well under half the price, helped by a meaningfully upgraded local dimming optical stack, and the Onkyo-tuned audio punches above its weight. You give up viewing angles to the VA panel, and the Google TV firmware still has rough edges.

Strengths

— Peak HDR brightness around 2,600 nits on the 65-inch model — within striking distance of premium mini-LEDs costing three times as much
— 144Hz native refresh, ALLM and VRR, Game Accelerator 288 mode — strong gaming feature set at the price
— Anti-reflective screen coating handles bright living-room ambient light better than the Hisense U7N

Watch-outs

— Only 2 of 4 HDMI ports are HDMI 2.1 — trails the LG OLED G4 and Samsung QN65S90D
