WebDoodles - Online Screen Tester

The table above shows the screen resolution and colour bit depth of your current monitor.

SCREEN RESOLUTION:

This is the number of rows and columns used to create the image on the screen.

CLASSIC MONITORS (NON-WIDESCREEN)
1600 X 1200 pixels (UXGA) is found on 21 to 19 inch monitors.
1280 X 1024 pixels (SXGA or XVGA) is found on 19 and 17 inch flat screen monitors.
1024 X 768 pixels (XGA) is found on 15 inch flat screen monitors.
800 X 600 pixels (SVGA) is found on older computers, e.g. Windows 98 and Me.
640 X 480 pixels (VGA) is found on Windows 95 computers but is now defunct.

WIDESCREEN MONITORS
1920 X 1200 (WUXGA)
1680 X 1050 (WSXGA+)
1440 X 900 (WXGA+) is found on 17 inch laptops.
1280 X 800 (WXGA)

These figures are intended as general guidelines, since monitors of different sizes are available with a range of screen resolutions.

COLOUR BIT DEPTH:

This is the number of bits (ones or zeroes) that the computer allocates to each pixel.

32 bit colour depth is found on modern computers.
24 or 16 bit colour depth is found on older computers.

PIXEL DEPTH:

The pixel depth display may not work in all browsers. Pixel depth is the maximum number of colours that can be displayed by the screen at one time. For 32 and 24 bit pixel depth this is around 16.7 million colours (known as Truecolor or Millions of Colors for Apple Mac users), while for 16 bit pixel depth it is 65,536 colours.
