|Hi everyone, the following very strange thing is happening to me:|
I am running Vista 64 SP1 on a computer with Asus P5kSE, 4gb RAM, and a Q6600 2,4Ghz, and ATI Radeon 2600PRO. I am using 2 22" LCD monitors, with VGA cables and DVI adapters on the graphics card. I have been running this system for 3 months now, and all this time both my monitors worked fine, as STANDARD PNP MONITORS, 1680x1050.
This morning upon bootup only one of them became STANDARD UNPNP MONITOR, and is stuck to standard resolutions going up to 1600x1200, but not its maximum rezolution of 1680x1050, thus the image looks relly wrong. The other monitor works fine, STANDARD PNP, 1680x1050.
I reinstalled the ATI driver, tried to uninstall and reinstall the monitors, rebooted many times, nothing. The ATI Catalyst utility is telling me I have 2 monitors, out of which one it can recognize and give me even the model number on it, which checks on the back of the monitor, but the other one is just a standard vga, and nothing else about it.
I have searched the forum and read another thread, but I believe what is happening to me is different. 2 identical monitors, on the same card, one of them works, one not so well.
Could this be a hardware problem? Is one of the monitors broken? I cannot see other signs other that Vista is saying UNPNP.
The monitors are both PNP and thus have no drivers to install. I am really stuck, my desktop is awful now and I need to get on with a webdesign project...
Any help is hugely appreciated.
