Troubleshooting LCD Dipslay Issues
In the past, CRT monitors could display lower resolution in full screen as they are not confined by the number of or pixels in general; pixels were not used in CRT monitors. This presents a different set of solutions needed to correct low quality pictures on an LCD screen. An LCD monitor has to spread the lower resolution over the native or highest resolution of the monitor. This creates problems when the lower resolution does not divide itself equally into the pixels of the width and height of the native resolution.
For example: a native resolution of 1024 by 768 will have low quality images if set to 800 by 600 resolution because the pixels cannot be distributed evenly from the 1024 to the 800 and from the 768 to 600. This results in some image pixels being displayed over 2 hardware pixels while other image pixels are displayed over one hardware pixel; the resulting resolution works, but is not very attractive. If you have to display at a lower resolution that can not evenly divide into the native resolution find the display options for your monitor. In this utility you will find parameters to change to improve the image quality.
First start with the contrast ratio as this can be the simplest to change and you may not need to change anything else. If the image seems blurred then increase the ratio in small increments to see the effects; this may take several tries. Next try the color settings of the monitor and pay close attention to the hues of colors seen on the monitor, i.e greens, blues and yellows. This is best done in a low light area to gain the full effect first. After adjusting the color settings in the “dark” turn on the lights and adjust until you have the desired result. This will improve the picture as best as you can; however, the best action to take would be to leave the LCD monitor at its native resolution.
