IsMyLcdOK is a small program but effective solution to easily check for dead/paralysed/stuck pixels on LCD monitors.
Many manufacturer's provide the highest industry standard dead pixel policy.
IsMyLcdOK does not have to be installed and can be executed easily from the desktop,
and can be carried on a small usb-stick or other memory device.
Testing for dead pixels is very simple ;) from the Category Test Tools for Windows
# Pixel Tester with different colors and gradient:
[1] = White Test
[2] = Black Test
[3] = Red Test
[4] = Green Test
[5] = Blue Test
[6] = Cyan Test
[7] = Purple Test
[8] = Yellow Test
[9] = Gradient horizontally
[0] = Vertical gradient
[F7] or [V] = Vertical lines
[F8] or [H] = Horizontal lines
# Small graphics stress test:
[F2] = BitBlt MB/sec. Test
[F3] = Paint Rectangles
[F4] = Paint Linies
[F5] = Endurance test
as reviving pixels:
Screen freezing plays a random combination of red, green and blue colors at a rate of over 60 frames per second to bring the stuck/paralyzed pixel back to its normal cycle. Let the color flashing graphic run for a minute or two.
With a little luck, some or all of the paralyzed pixels will be revived. This works because in a stuck pixel the fluid is not evenly distributed in one or more of its subpixels.

# Layout:
IsMyLcdOK is primarily designed to quickly become the main feature of the program and that is the search for dead or paralyzed pixels. It is a fairly simple and small test program that can be of great benefit to all PC users. This software requires no expertise in terms of monitors and LCD-s, nor any expertise in the field of screen technology. All PC users can benefit from IsMyLcdOK from the first second
# Usability:
When you start "IsMyLcdOK" for the first time on your PC, you will see a license on the screen. The program is of course free for all, the license info is only displayed the first time (per PC). IsMyLcdOK shows you without detours and immediately at program start all features and test options. However, these can also be called up at any time with the F1 key. From here, you have access to multiple tests that depict colors, gradients, and lines that help ti locate dead or paralyzed pixels. From version 1.01 I added a little "Paint Stress". This will put your LCD under stress simply by the F2 key. You can quit the program at any time with the ESC key.
