PiXel Check overview

PiXel Check is an application that assists you in visually inspecting your LCD for bad or "dead" pixels

The concept is simple - select a test color, and PiXel Check will put up a screen to allow you to check the specific pixels

"Red" activates all red piXels, "Blue" activates all blue pixels, and "Green" activates all of the green piXels. The "Black" and "White" tests activate or deactivate all red, green, and blue pixels respectively

The reason that red, green, and blue are the colors that are checked for is because each pixel on an LCD is actually made up of 3 separate transistors - red, green, and blue. When all of the transistors are turned on, you see black, and when all of them are turned off, you see white - the reason why there are also black and white check modes

The app does not extend to the complete borders when using the AirPlay Display to an Apple TV and needs to be updated to effectively test an HDTV!

Works great on my Intel iMac. Performs as advertised with no known downside. It doesn't do much, but what it does, it does well, very well, And, Rosetta is no longer required. Many thanks to all those who brought this to pass. Bravo!

Excellent little program, cycles through all the primary colours plus black and white. All you need to test your LCD for bright dots or dead pixels (many LCD manufacturers have 30 day zero bright dot policies) Also free which is what you want for something you may only test once every few years. Would be nice if this was ported to intel though. Takes a while to launch on startup.

Excellent tool, and don't get thrown off by the fact, that it hasn't been updated in four years. If it ain't broke, don't fix it, right? Does what it should, and does it very, very well!

I happened on this utility via a review of something else in ars tecnica. Pixel check is great: fun to use and useful. And, a technoDolt like me can do it. Superb. Thank you. Joseph A. Stirt, M.D. http://www.bookofjoe.com 'world's only blogging anesthesiologist'

Mac OS 10.3.4 on a 20 in fp iMac had no trouble using this test. It does the job great. Thanks. May we all remember the Columbia and her brave crew.

Sounds great - but what do you do if you find dead pixels? Does it cure them? What's point of the application?

I checked my iMac monitor out of curiosity, great little utility. Good news for me, all is well! Thanks!

I downloaded this following an Ars Technica review, curious to see if there were any dead pixels I didn't know about. I've yet to run it but ... ... I'm a space buff, and I wholeheartedly approve of the dedication for this software.

Simple and easy to use, great little utility. (os 10.2.5,17 inch Imac) And by the way, I have a dead pixel and my mac is only 6 months old, DOH!!! Lucky for me I bought CompUSA's warrenty for my moniter.
