Hi! I'm a computer-based graphic artist and also a photographer who does digital editing. THe difference between the display settings makes a big difference. Using 32 million colors rather than 16 million is significant for image quality. Also check your display's resolution settings.
Right-click on the desktop background. Select "Properties". Go to "Settings" to find Screen Resolution and Color Settings adjustments. Clicking the "Advanced" button gives you more options.
One final idea:
Check to see if you are using the correct display adapter (driver), and that it is the most up to date one. A generic, incorrect, or obsolete driver can affect visial performance.
You could have an inverter board problem. The inverter supplies high voltage to the CCFL lamp which provides the back-lighting.

The graphics card won't initialize unless the system passes certain internal checks; most of the time this is caused by the wrong RAM configuration. Make sure the RAM you are using is the right type of RAM for your system; in some cases the system board will still power up with the wrong RAM installed. Then check monitor connection to make sure there are no bent pins on the connector. Furthermore, I'd even check to see if the system boots without any RAM installed.
are you using the onboard graphics card? if yes try using a plug in card in the AGP slot to see if it makes a difference.It sounds like either an onboard graphics chip problem or a motherboard problem. come back to me for more emachine support, One of my specialised fields is in these computers.
Try replacin a new display card. If it is fine working.ok
If not try fixing for cold solder in the video section.
I suggest video section according your report the light green LED lighted that shows the power section is doing fine.
Pls reinstall the drivers for the graphics card and restart the computer and check if it is working.
If it does not work, then download the original drivers from the computer manufacturer or the graphics card manufacturer 's website and install them. Make sure that you have uninstalled the drivers before reinstalling any drivers.
Also pls look for any updates for the graphics card.
This sounds like your resolution is set too low,
right click on your desktop and select properties
Choose the settings tab from the window that appears, then you should be able to see a slider that tells you your screen resolution.
This is most likely set to 640 x 480, the setting you want should be in the region of 1024 x 768
If you are unable to change this setting, you need to check that your display adapter drivers are installed properly in "Device Manager"
