The TCL 65" Quantum Mini LED 4K UHD TV (Model QM8). And the Sony A90J OLED 55" 4K TV represent two distinct approaches to large-screen 4K viewing drawn from aggregated public reviews and manufacturer specifications. The TCL model delivers a 65-inch panel with Mini LED backlighting that supports 144 Hz refresh rates. And strong peak brightness levels, paired with an accessible price point around one thousand dollars. In contrast, the Sony A90J relies on its 55-inch OLED panel to produce exceptional contrast and inky black levels, supported by a more refined build quality. And processing that reviewers consistently rate highly for color accuracy and motion clarity. Differences in screen size, refresh rate, and overall cost become immediately apparent when comparing the two side by side. The short version: choose the TCL 65" Quantum Mini LED 4K UHD TV (Model QM8) if screen size, refresh rate. And value matter most, or the Sony A90J OLED 55" 4K TV if deeper blacks and premium refinement take priority.

Verdict: Pick Sony A90J if you prioritize OLED contrast and lower energy costs (23 dollars/year) despite the smaller 55-inch size. Neither publishes peak brightness, HDMI 2.1 ports or VRR / ALLM yet.

Sony A90J OLED 55 4K TV lists at $19.99 while TCL 65 Quantum Mini LED 4K UHD TV Model QM8 lists at $899.99 — Sony A90J OLED 55 4K TV undercuts TCL 65 Quantum Mini LED 4K UHD TV Model QM8 by $880 (4402%).
