Question about ViewSonic VX2235wm LCD Monitor
I just purchased a 22" Viewsonic LCD. It is an HD1080p monitor supporting a max resolution of 1920x1080. I have it connected to an ATI x600 Radeon video card via DVI. The monitor has a DVI-D input, and the video card has a DVI-I output.
The problem I am having is that when I turn off the monitor while the computer is on then turn it back on, the monitor does not detect the DVI signal. This also happens when I switch the input source on the monitor. The only way to restore video over the DVI connection is to either reset my PC or just reseat the DVI cable.
When I boot the computer, the I get my bios screens and I have video when I boot into windows XP. I can let them monitor go into sleep mode and it wakes up fine, and really the monitor works all the time. It does not shut itself off nor have I ever lost the screen while working. Only when I shut the power off or switch inputs does it lose the DVI signal and it can't seem to detect again when switched back. I don't really think it is a monitor issue but I do not understand much about the EDID and DCC connection to know if there is something kind of corruption in its plug and play file or if its pixel timing is off.
Then your monitor is worn out. You could take it to a repair shop to get it fixed or buy a new one. Hope this helps!?
Please rate solution - Thanks

You are having a firmware issue or the main board is bad. Since you cannot get the monitor to work from either connector, and since this is a high resolution monitor, I doubt you are having any operating system issues. You can test the monitor on a laptop or another computer if you desire, however from the symptom it looks like the main board requires some attention. Contact Viewsonic at viewsonic.com or call their 800 number for service information. You could order a main board, but it may not have the ddc data programmed (similar to firmware) so you may have to bring it or send it to a shop for service. BTW, they have three year warranties. I would recommend calling Viewsonic.
