Check refresh rate, color gamut (sRGB, P3, Rec.2020), HDR support, and screen resolution.

Cycle through solid colors to spot dead or stuck pixels on your screen.

Check your camera resolution, framerate, and video quality.

Test real-time ping latency, jitter, packet stability, and WebRTC STUN connectivity.

Stress test all processor cores with intensive calculations to reveal thermal throttling.

Stress test your GPU with 3D WebGL fractal shaders and measure FPS stability.
