VGA and DVI monitors

[hrlslcbr]

Hello. I have a small (stupid...) question about both analogue and digital displays.
Can I connect and disconnect a CRT or LCD display while the PC is on (for both DVI and VGA connections)?
I assume it is possible (without damaging the display of course) because sometimes Windows XP detects a monitor as a 'plug and play monitor' when the driver isn't installed.


Thanks.

Generally, yes, in my experience. I would use a switch for that purpose, not just unplug the monitor. You may have problems with the OS finding the new monitor, though. I think most may say you should reboot the computer if you change monitors. But it should cause no damage to the monitor; AFAIK.

Thanks.
Any other comments (like someone destroying their monitor because they disconnected it while the pc was on)?

Nothing like destroying the monitor. I did have to fix one person's PC because they adjusted the monitor settings and their display went blank.

When they restarted, they could never get it to display. SO I restarted the PC with the monitor disconnected. After about 3-5 min. I connected the monitor and the picture showed up, so I could adjust the display properties to default.

Not exactly sure why it worked, but it did. My next step was to run it in Safe mode, but didn't even need to go that far.

It is theoretically possible for a static charge to occur at the connecting time and possibly damage the monitor or the PC video card, most manufacturers instructions state that the plug should only be connected while both units are off. This may be more of in issue in areas with very dry air, prone to static discharges. I live and work in Florida where carpet sparks are extremely rare due to the humidity.

I have never, in almost 20 years in the PC repair business, seen or even heard of such a situation wherein this type of damage has occurred, or even been suspected.

Thanks everyone for your answers . There isn't much humidity here, so I think static discharges are unlikely.
Thanks again.

Actually, the less humidity, the easier to get static build-up. I live in Vegas. I have a throw carpet from When I lived in NY. Never had any discharge from walking on it until I lived here in Vegas.

I actually bought a few 20"x20" stone/ceramic tiles, from Home Depot, to place my PCs on. The areas where they are is all carpeted. Also keeps the feet from being stuck and hidden debris from creeping in.

Yeah... you're right...
