Plus it's super expensive on smaller displays so only OLED TVs are feasible for most people. Each pixel can be as dark or as bright as needed but the overall brightness is usually lower than on LCDs. The drawback is that the number of dimming zones again determines how well it will work and it can show as halos around bright objects like icons because the local dimming will consider say a cursor to be a very bright object.
Much better contrast, can handle the brightest and the darkest. The more dimming zones the better, but they tend to do well for very bright scenes but can look dull for ones that mix dark and bright because the local dimming will be on even in the dark areas if there are not enough dimming zones, resulting in grey blacks and so on. Edge lit dimming which you will find on most cheaper displays and TVs with HDR support.No local dimming means the display can't regulate its backlight to increase contrast.Ok, now we have 1000 nits peak brightness, that's good.īut then we get into other issues which is the backlight: Basically they can read HDR metadata but can't do much with it because they don't have the contrast or brightness needed to show the difference. HDR on computer displays is no different from TVs, meaning you will get varying levels of quality in about this order:
