DVI input on monitor not working

Hi, I recently unplugged my monitor from my main machine (using the DVI) to use on another computer (using VGA). When I returned the monitor to my main computer and connected it using the DVI cable, the monitor was not receiving any signal. Now I can only get the monitor to work with the VGA cables. I have tried several DVI cables and they all do not work (even though they work with other monitors). Everything works fine with VGA cables on multiple computers and not at all with DVI cables on multiple computers. I figure that I must have messed something up with the DVI input on the monitor when I was plugging in the cables or something. Anyway, I was wondering if this is a fixable problem. Thanks!

    I have also exactly the same problem, I unplugged it once from DVI and plugged VGA in, and when I plugged DVI back it wasn't working in windows, but it gives the picture during POST and boot screen but after that finishes, only VGA works. My monitor is Samsung SyncMaster 731BF, and I have the latest ATI drivers.

    I need to know , does the setting First monitor (1) and Second (2) monitor or ext has been done ? If the setting is not been done yet... of course the screen would turn up to be the same.



    Have a try.

    TIA

Contacted viewsonic about this issue- they suggested- have both dvi and vga hooked up to same machine. start with poweroff on both. power on monitor, then power on computer. when you see display coming from the vga, power off pc, then disconnect vga cable, turn off power to monitor, disconnect power cord from monitor for 5 + seconds, reconnect power cord, power on monitor, then power on pc.
If this doesn't work to get the dvi working, (as happened to us) we returned our monitor for a replacement, since it was still under warranty.

I can't get either of my 2 computer monitors to work through my DVI D cable, both monitors work through a VGA cable, just the DVI wont work, what is wrong?


dvi cable most likely will only work as a second monitor rather than as a primary monitor. Suggest checking you computer video card specifications to see if this is the case.

What connections are required


Make sure the monitor works on a friend's PC using the DVI... let's not go backward to VGA when DVI is available on both the PC and monitor. If the monitor works, install the driver and reboot. It should work for you too.

Trying to set up 3 monitors in windows 7. using on board dvi to connect to one monitor and on board vga to connect to switch box (which then splits video signal to two vga monitors). can only get the dvi...


Sometimes it is difficult to answer a question without asking very basic questions. Using a DVI and a VGA ports will allow you to have screens with different things showing on them. If you use a splitter, the two monitors connected to the splitter will show the same thing on both screens. Is this what you want? I use a splitter at church to have Powerpoint on the main computer monitor, the program then shows on the screen on the wall and the TV monitor, as well as the second monitor at the computer. My splitter occasionally acts up, and I found that unplugging it and plugging it back in makes it work for another couple months. But a splitter for only two monitors is very cheap, no switch box involved.

My monitor is blank, the Acer logo will flash on when I start it but cannot get a signal, have tried it on another machine same response.


Hi,

I am not too sure if you have tried this but this might help, for what i know your monitor have 2 ports for video (DVI and VGA). VGA is the one with color blue adapter, while the DVI is white. If your using VGA for both computer might be you can try DVI or from DVI to VGA. Also try a different cable for both VGA and DVI. If still the same might as well contact the Acer and check the warranty, normally monitor had 2-3 years of warranty, Have it replace if still under warranty.

I hope this works on your issue.

thank you for choosing Fixya.

Hi, I get a No Signal message when I connect a DVI card. Does this monitor support this type of card? Regards, Pete


Hi Pete Not sure what you mean by connecting a DVI card.
This monitor is analogue only and must connect to the computer via a VGA connector. Are you using a DVI to VGA converter?

TODAY AFTER ONE YEAR WORKING PERFECTLY,MY E-MACHINE GATEWAY MONITOR,SHOWED :OUT OF FREQUENCY RANGE AND TURNS BLACK,AND COMPUTER HANGED FOR A WHILE,TILL I UNPLUGGED FROM POWER CORD AND REBOOT IT. WHAT WAS...


If the computer hangs for a while and reoots and then works the monitor, it tells me that the signal to the monitor went dead until rebooting. It is as if you unplugged the monitor from the vga or dvi card, or it was getting an incorrect signal from the vga or dvi card. It may not be the monitor, so much as it is the computer doing this to the good monitor.
One can test to see if the monitor is bad by using it on another computer tower or desktop to see if it does it there. Good luck on this diagnosis.

CHANGEING MONITORS


Hi Laura and welcome to FixYa!

Yes, you should be able to change your monitor. You will notice that if you unplug your monitor's cable from the back of your computer, you will see an adapter that looks like the one below (called VGA).

I can't seem to find the specs on the new monitor you mentioned, but most new LCDs (flat screens) have DVI cables, which look like the picture below.

Don't worry, its an easy fix. Go down to your local electronic store and ask for a "VGA to DVI converter". It will look like the one in the picture below. Mine cost me about $8 USD.

I hope this helps. If you have any questions, do not hesitate to ask.
