|Color depth||68 × 109[dubious ]|
|Response time||1–8 ms typical (according to manufacturer data), older units could be as slow as 35 ms|
|Frame rate||60–85 fps typically, some CRTs can go even higher ("200 fps at reduced resolution");
internally, display refreshed at input frame rate speed
|60 fps typically, some can do 120 fps;
internally, display refreshed at eg. 480 or 600 Hz
|Environmental influences||High altitude pressure difference may cause poor function or buzzing noises|
|Flicker and eyestrain||Depends; as of 2013, most LCDs use PWM (strobing) to dim the backlight which can cause severe eyestrain for some people although the flicker isn't visible because it is normally done at 200 Hz or faster|
|Size||Up to 150"(3.8m)|
|Energy consumption and heat generation||High||Low
with CCFL backlight 30–50% of CRT, with LED backlight 10–25% of CRT
|Varies with brightness but usually higher than LCD|
|Maintenance||Hazardous to repair or service due to high-voltage,
requires skilled convergence calibration and adjustments for geographic location changes
|Electro-magnetic radiation emission||Emits strong radio-frequency electromagnetic radiation|
|Other||The LCD grid can mask effects of spatial and grayscale quantization, creating the illusion of higher image quality.
Many newer models are powered by an external 12V power supply (for thinness), and could (with a special cable) be connected directly to the computer's power supply, possibly saving power, desk space and wall-outlet space
|Screen-door effects are more noticeable than LCD when up close, or on larger sizes;
fragile and required to be upright to avoid screen collapse
