|Static Contrast ratio||Over 15,000:1||150 to 6,600:1||3800:1||"∞" "Inf:1" Unable to be calculated as black levels are zero.|
|Peak Luminosity||176 cd/m²||276-1460 cd/m²||50-200 cd/m²||100-700 cd/m² |
|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||8 to 10-bit per subpixel, with some HDR models capable of 12-bit per subpixel.|
|Response time||0.01 ms to less than 1 µs||1–8 ms typical (according to manufacturer data), older units could be as slow as 35 ms||Typically less than 0.001 ms, as low as 0.00001 ms||Estimates varying from under 0.01 ms to as low as 0.001 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, gaming monitors can do up to 240 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
|60 fps typically.|
|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.|
|Energy consumption and heat generation||High||Low
||Varies with brightness but usually higher than LCD||Varies based on image brightness and color.For the majority of images it will consume 60–80% of the power of an LCD.
|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||Can have poor brightness.|
|Electro-magnetic radiation emission||Can emit a small amount of X-ray radiation.||Only emits non-ionizing radiation.||Emits strong radio frequency electromagnetic radiation|
|Size||Up to 43"||Up to 108"(2.78m)||Up to 150"(3.8m)|
|Maintenance||Hazardous to repair or service due to high-voltage,
requires skilled convergence calibration and adjustments for geographic location changes.Glass display tube is evacuated and carries risk of implosion if improperly handled.
|Risky and expensive to repair due to complexity of the display; units with mercury lamps are a minor environmental hazard||Screen itself cannot be repaired if the gas used to generate images leaks|
|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.Extremely bulky and heavy construction in comparison to other display technologies. Large displays would be unsuitable for wall mounting.||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;
Risk of image retention or 'burn-in'.
|Risk of image retention or 'burn-in'. Coloured sub-pixels may age at different rates, leading to a colour shift. Sensitive to UV light from direct sunlight.|
