|Contrast||Over 15,000:1||5,000 to 10,000:1||10,000:1|
|Color depth||24-bit per pixel resolution; offers better resolution for grayscale||6 to 10-bit per subpixel panels; smaller dot pitch, better detail||6 to 8-bit per subpixel panels; best color gamut|
|Response time||Less than 1 µs||1–8 ms typical (according to manufacturer data), older units could be as slow as 35 ms||Less than 1 µs; can get up to 0.001 µs|
|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 up to 240 Hz
|60 fps typically, some can do 120 fps;
internally, display refreshed at e.g. 480 or 600 Hz
|Environmental influences||Sensitive to ambient magnetic fields, which can adversely effect convergence and color purity.||Prone to malfunctions on both low (below -4 °F\-20 °C) or high (above 45 °C\113 °F) temperatures||High altitude pressure difference may cause poor function or buzzing noises|
|Flicker||Perceptible on lower refresh rates (60 Hz and below)||Depends; as of 2013, most LCDs use PWM (strobing) to dim the backlight||Does not normally occur due to high refresh rate.|
|Size||Up to 43"||Up to 108"(2.78m)||Up to 150"(3.8m)|
|Energy consumption and heat generation||High||Low
||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
|Risky and expensive to repair due to complexity of the display; mercury lamps make it a minor environmental hazard||Screen itself cannot be repaired if the gas used to generate images leaks|
|Electro-magnetic radiation emission||Can emit a small amount of X-ray radiation.||Only emits non-ionizing radiation.||Emits strong radio frequency electromagnetic radiation|
|Other||No native resolution. Currently, the only display technology capable of multi-syncing (displaying different resolutions and refresh rates without the need for scaling). Display lag is extremely low due to its nature, which does not have the ability to store image data before output, unlike LCDs, plasma displays and OLED displays.||The LCD grid can mask effects of spatial and grayscale quantization, creating the illusion of higher image quality.
||Screen-door effects are more noticeable than LCD when up close, or on larger sizes;
