Know everything about your Apple computer display
If you own an Apple computer, and want to know all features of its LCD display, you just have to follow these steps.
First of all, download “SwitchResX Control Panel” then start it. When it's done, click on “Export DCC” button. You will get a text file you'll have to open.
LCD panel reference is at the end of file, presented as
Descriptor #2 is ASCII data: B133EW01 V0
Then you have to start you preferred search engine to search for the panel reference (first part, without version number, in this case “B133EW01”). With my MacBook, I can see it's a TN LCD panel, the brand is AUO, response time is 25 ms, contrast ratio is 400:1, number of colors is 262 000, etc.
About color numbers, a class action was started into United-States against Apple which pretends on its website that LCD panels can display millions of colors but it's not the truth.
