I have a new PC. It is a Lenovo THINKCENTRE M75E ATH X4 640 3.0G 2X2GB 500GB DVDRW W7P. Lenovo's Model number is: 5041A3U
On this PC I have installed 2 identical ASUS 24 inch Monitors and I have extended the desktop onto to them. The problem that I have is that after 45 seconds the monitors dim to a fairly unusable level. We have tried setting computer options and also setting Monitor options with no success.
Do we need to add in a video card? We have been using the 2 onboard ports, 1 VGA, and 1 DVI to connect the screens. How do we get some “normal” brightness onto the screens?
Any suggestions would really be appreciated. Thanks
