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

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.

Yup, a Universal version would be handy so I can still keep Rosetta off my Intel systems.

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!

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?

They already said it was to find dead pixels.

To bring them back to life, try massaging them. Not to hard though.

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.

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.
