Can You See a Pixel?   Click here to reveal an image measuring 400 pixels square with a single yellow pixel illuminated at the very center. Use a loupe or magnifier to examine the yellow pixel.

Depending on the type and quality of your display, the pixel may appear crisp and sharply defined or somewhat blurred. Keep in mind that typical displays use a combination of Red Green and Blue to create primary colors. The subject pixel will actually require both a Red and Green segment to produce yellow.

Subject: Question/Comment for the webmaster at pixelyzer.com
For video if you are displaying 1080i are the total number of pixels constant for any size screen are the pixels just larger or more of them?
The specification calls for 1920 X 1080 pixels. In practice, many displays average the matrix up or down to match the native resolution of the device. And, yes, 1080i can display on physical devices anywhere from 4 in to 72in ETC. obviously, the size and spacing (pixel density) will vary according to the physical size being observed.

On larger devices, individual pixels are quite apparent when you are near the screen. Conversely, If there are dead pixels on a hand-held device, it would be hard to tell because the individual points of light are so tiny.
