This 2021 budget OLED is pure contrast: true blacks and precise color, though it skips high refresh and VRR. All HDMI ports run at 2.0 spec, maxing out at 4K@60Hz — high refresh gaming is off the table here. eARC runs on HDMI 2 for lossless audio return to a soundbar. Here's every port and the cables you'll need.
2021 LG budget OLED A1 with α7 AI Processor Gen4. 60Hz panel only, no VRR, HDMI 2.0 ports. Entry-level OLED.
