I have a monitor that I have connected to 3 different desktop computers and it has worked intermittently on all 3 at best. I have tried changing video cards and drivers but it makes no difference. However, when I connect this same monitor to my laptop it works everytime. Any idea what is going on here? I am really frustrated with this and ready to throw the monitor out the window

This is not a tech support forum...it is a comic relief site for technicians in the trade.

Joke. You're saying that it won't work right on the PC not matter what video card/drivers you are using, but it works "no prob" on the laptop, right?

Have you tried matching the refresh rates on the desktop to those of the laptop? What kind of issues does the monitor have on the PC? Be very descriptive and specific.

I guess I should have inserted a smiley face.

But if I were to speculate, I might suggest that it might be related to the monitor's optimal refresh rate and/or how the refresh rate is configured on each graphics card. But without knowing the manufacturer and model of the monitor, or the manufacturer and model of the graphics cards, and how the graphics cards are configured, it's no more than a guess. Have you tried to install the drivers for that exact monitor?

By the way, if you're asking for help on a technical issue, you'll probably get more (and better) replies from the "Ask For Help" section. Just follow the "Ask For Help" tab.

I can't refresh because I can't see anything. The screen is completely black. It is like it receiving power because I can see the lights light up but not receiving a single from the monitor because the screen is black and the power light starts to flicker

If it is at all possible, you will need to grab another monitor because we need to be able to manage your pc in the desktop environment. Do you even see the POST? (the screen that you see when first starting your pc)

It could be that either the refresh rate is too high or your video card is not getting enough power. If it is the power issue - remove some un-needed devices temporarily (pci) - or use a different power supply.

If you can try a different monitor...
Right click desktop... properties... settings... advanced... set the refresh rate to a standard 60-70 max.

It could very well be that the monitor is pooched, but since it works on the laptop...you said that you tried 3 different desktops too?

Unfortunately, I don't even see the post but I appreciate your explanation. I did try a second monitor with the same results (didn't work with desktop but worked with laptop). It is baffling because originally, the desktop had onboard video which failed. I was able to disable onboard and enable the new card but hasn't worked properly since. I will try with a 3rd monitor.

Is you notebook older? Perhaps a lower resolution 640X480

Maybe your 3 desktops are running at 800X600 or higher?

but I found out how to fix the monitor. I removed and replaced the jumper on the mother board and presto chango the monitor worked.

thank you for your suggestions inspite of me placing this question in the wrong forum

It's sounds like it is not receiving a signal from the graphics card.

You should check the power management settings in the BIOS, unfortunately this means you will need to borrow another monitor if can't even see the BIOS /setup screen.

Also you say that the onboard video was disabled when you added the new card, have you tried removing the card, checking it with the onboard chipset and setting the card up again, new drivers check power management etc.

It sounds like the onboard has been re-enabled or the card is not recognized/sending a signal, the power light flashing on and off is a key issue here.

You haven't mentioned what type of vid cards you've tried, agp or pci slot based? I've had this problem occur many times in older 586 systems when trying out pci slot based vid cards and ending up clearing the cmos everytime to get the system to recognize each different vid card I was testing. The laptop sees the moniter differently since it's attached as a 2nd moniter and not as the primary.

I was using a PCI card on one computer and APG on another computer...and you are right, I have to clear the CMOS everytime.

by dnixon

Try safe mode boot (F5 to go straight there or F8/F12 to get to an option display)and adjust refresh rate there. Then reboot in normal mode

Have you bought as PCI Express Video Card to use in your Desktop? If so it will not work with a standard PCI slot and you will be getting exactly what you are describing as the monitor isn't receiving a signal from the Video Card.
