Re: lcd flat panel
I'm sorry, but it sounds like you have a damaged LCD panel, and that can't be repaired. Check carefully to see if it's just the outer plastic that has cracks, but if the lines seem to be "electronic" colored lines you're probably out of luck.

Did you change the HDMI cable? If so, you should check to ensure you have the cable installed so it is running the right direction. It may seem hard to believe but some HDMI cables only allow the signal to run in one direction.
On the monitor, press Menu, and select Factory Reset.
If the monitor has more than one type of connection available such as VGA, DVI, or HDMI, try a different type of connection.
Connect the monitor to another computer. If the line appears when the monitor is connected to the second computer, the monitor might be damaged or defective.Otherwise, the video card and driver is causing the problem from the computer.
let me know if this resolved ur issue.. regards,guru
Use the CTRL-ALT-ARROW combination to flip the screen around. This is a problem that occurs when someone goes to press ctrl-alt-del and hits an arrow by mistake and does not realize it. I work the help desk in the I.T. department at a major hospital in south Alabama and several of the users have had this problem with Windows XP. You may have to try different arrows until you get the screen turned right side up.
I guessing that since **-one responded you've given up and returned the whole mess but what the hey.
A lot depends on the KVM you're using. There are some high end units that will match different sources to the monitor but most work best with matched input and output. Unless you's specifically states that it will convert analog to digital it won't. So if it's an analog KVM then both the computer video boards need to have an analog VGA jack and the monitor does too. If the KVM is ditital you need to have all the systems and monitor digital. Savi? The Monitor may support boath analog and digital input but NOT at the same time. You can't plug in two computers at the same time, that's what the KVM is for.
The bottom line here is that you typically need to run the least common de**minator to use a KVM. Also, if the computers have different frequency (resolution) out put and you hit the KVM switch then the monitor will freak out. Some monitors will auto-switch between frequencies but most don't (especially the cheapies).
There are adapters that will down convert digital to analog. If you're dead set on using the KVM with that old Dell then you may need to plug the down converter into the Acer Video Board but you'll loose the high resolution and sharp picture from the digital video. If it was me and I had to use the KVM, I'd get a cheap digital video card for the Dell or just run two monitors.
I run 5 systems on my desk, Three of which are older servers with analog video. They share an analog KVM with video and keyboard on the wall. The other two systems are current generation and share a KVM and 27" flat panel center desk. I also have a laptop that hangs on the other wall with a laser blue tooth keyboard on the other side of my desk. Now if my wife would only let me turn part of her craft studio into a server room.....
