Question

How can I change the brightness & resolution on my NEW acer x193w monitor? The instruction booklett is verv unspecific! I am alsi finding that certain programmes are responding a lot slower than ever before. I have a DELL 4300 with only 1/8th of ysed space on my hard drive. Please advise OR advise ne who I need to ask about this problem? My old (very old) monitor gave me none of these problems. Thank you, Your fastest reply would be appreciated very much.Tim [e-mail].
