Dell Inspiron 3000 Reference and Troubleshooting Guide

The second screen is the red/green/blue (RGB) color 
combination screen. This screen allows you to test the 
ability of the display or monitor to increase or decrease 
the intensity of the three basic colors.

The RGB color combination screen displays an RGB box 
in the top center of the screen with individual red, green, 
and blue boxes beneath it. Underneath the individual 
color boxes are three lines that show the intensity of each 
color. Type 

r

, 

g

, or 

b

 to adjust the intensity of the corre-

sponding color; then press the right-arrow key to increase 
the color intensity, or press the left-arrow key to decrease 
the intensity. Type 

y

 if all the squares are the correct col-

ors; otherwise, type 

n

. 

The Solid Colors Test checks whether the video sub-
system is displaying the correct colors. This test also lets 
you check for missing pixels. When this test is running, 
four screens appear sequentially—a red screen, a green 
screen, a blue screen, and a white screen. Check each 
screen for missing pixels, and verify that the correct color 
is being displayed. 

When the test is complete, a message asks if you are sat-
isfied with the quality of the colors. Type 

y

 if all the 

pixels were present and if the correct colors were dis-
played; otherwise, type 

n
