Grill_11, Grill_22, Grill_33, Grill_44

Description

The entire active video area is filled with

 

alternating black and white stripes. The stripes

 

are drawn at different resolutions. Each of the

 

stripes is four (4) pixels wide in the Grill_44 image

 

and three (3) pixels wide in the Grill_33 image.

 

Each of the stripes is two (2) pixels wide in the

 

Grill_22 image and one (1) pixel wide in the Grill_11

 

image.

 

The primary versions draw vertical stripes while

 

the secondary versions draw horizontal stripes.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Test

Verify monitor resolution

Purpose

The resolution of your monitor should meet or

 

exceed the design specs.

Method

First adjust the brightness, contrast, and focus to

 

their correct settings. You should be able to see

 

individual and distinct stripes in all areas of the

 

display at all four resolutions. Failure to see distinct

 

lines at the highest resolution (Grill_11) may

 

indicate you have a defective video amplifier or

 

picture tube.

 

 

 

 

Note – If multicolored lines appear on a mask-type color picture

 

tube, you may have a problem with convergence or you may

 

be exceeding the resolution of the picture tube.
