— For Windows systems, you should check the screen resolution and refresh rate (to do this in a no-video situation, you will have to connect a working monitor to the system).
— Control Panel >> Display >>Settings tab
— The Screen Resolution is generally shown on the left side, center of the window. It can be changed by sliding the arrow left or right in the box.
— Compare the resolution with the supported resolutions in the monitor specifications (on this site, see Products, select by monitor size, select monitor model number, scroll down to Resolution specifications).
— Note that LCD monitors have an optimum screen resolution.
— They will not display a resolution higher than the specified resolution.
— They will display lower resolutions, but the video quality will be diminished.
Also, check the Refresh rate.
— Click the Advanced button on the Settings tab.
— Select the Monitor tab.
— The Screen refresh rate should be displayed at about the middle of he Window. Other refresh rates can be selected by clicking the arrow at the right of the drop-down box.
— Compare the refresh rate with the Hz part of the resolution specifications. Use the drop-down box under the Screen refresh rate to try other refresh rates.
If these settings do not correct the problem, and if power and cable connections are OK, then contact Elo technical support for further assistance.
