HDMI supports resolutions from 480i/p to 8K (7680x4320). Common refresh rates are 60Hz, 120Hz, and 240Hz. Variable Refresh Rate (VRR) adjusts refresh rate dynamically
Refresh rate is the number of times per second a display displays a new image. Higher refresh rates reduce flickering on CRT displays. Refresh rate differs between raster and non-raster displays
TN uses voltage-controlled liquid crystal molecules that twist 90 degrees. IPS uses parallel crystals that rotate instead of twisting. VA uses vertically aligned crystals that tilt when voltage applied
Frame rate measures frames per second (FPS) displayed on a screen. Refresh rate indicates how many times the display updates per second. Both are measured in hertz (Hz)
Refresh rate is the maximum number of frames a monitor can display per second. Monitor's refresh rate is measured in Hertz (Hz). Higher refresh rate requires equal frame rate from GPU. Monitor's refresh rate depends on system's GPU capabilities
Refresh rate measures screen image refresh frequency in Hertz. Higher refresh rate means more images per second. Standard monitors typically have 60Hz refresh rate
