Response time measures pixel color change speed, affecting image sharpness. Input lag shows delay between source device and display response. Both measured in milliseconds and are interrelated but not identical
IPS displays use parallel liquid crystals with separate backlight. OLED panels have individual pixels that can turn on/off dynamically. Mini-LED backlighting in IPS can achieve OLED-like performance
Mechanical TVs were commercially available from 1928 to 1934. First mass-produced TV was Baird's "Televisor" (1930-1933). First electronic TV with CRT was demonstrated by Takayanagi in 1926
PS5 supports 1080p, 1440p, and 4k resolutions. HDMI 2.1 bandwidth and HDMI Forum VRR support essential. 27-32 inch screen sizes available, ultrawide not supported. Good motion handling crucial for minimal blur
Refresh rate is crucial for gaming at 120fps. OLED panels offer nearly instantaneous response time. Input lag affects controller responsiveness. Brightness and contrast are essential for bright rooms
Power consumption measured using Kill-A-Watt meter with checkerboard pattern. Tested in SDR with local dimming disabled and HDR with maximum brightness
