DVI Blank Screen Fix

For most people, buying a new screen is a simple task. Take it home, unplug the old one, plug tne new one, turn it on and there you go. For most people…

For me, it meant a whole decluttering operation*, desk cleaning, throwing away needless stuff, dusting, all sorts of things to make room for my brand new LG W53 22” monitor. I had already decided to keep my old monitor ( a 17” Philips) and use it as desktop extension, so I needed even more room.  After hours of sweating and sewaring, everything was in place and I only needed to push a couple of power buttons. Imagine my disapointment when the only thing I could see on the screen was black… Now really… I already knew that I could connect the LG through D-Sub connection and it would work fine, but I wanted to use DVI. I am not even sure that the picture quality is better with DVI, but I just could not settle for D-Sub.

I called a friend of mine, who said that he never had problems with his DVI screen. He thought that maybe there was a setting on my screen that I should change in order to force DVI input, and proposed the all time classic: RTFM. As you can imagine, the problem was not solved, so I started searching for a solution on the vast depths of the internet. It turns out that it is a common problem, affecting various combinations of screens and graphic cards, with no pattern of appearance. The solution that some people had tried and the one that worked for me was the following:

My radeon has two DVI outputs. I plugged the DVI cable to the main one, plugged the other end on the monitor. Then I plugged a D-Sub cable on the secondary output (with the use of an adapter) and plugged it on the D-Sub input of the monitor. So, I had the monitor connected to the PC with both cables at the same time. When I turned on the monitor, it first received analog signal (the OSD read “D-Sub”) but switched soon to digital. I disconnected the D-Sub cable and the monitor loched on digital signal. That was it. I have absolutelly no fucking idea why this was necessary, but it worked, so I don’t care.

In case you have the same problem, give this solution a shot. For some people it has all that was needed, for some others it only solved the problem temporairily, for others it did not work. But you never know…

    Sad but true! :p
    My LG monitor does the same sometimes. When it cannot detect an input signal in the mode it is set (dvi – vga or analog – digital) it “locks” itself and doesn’t accept input via the buttons as in turn off or switch to the other input.

    Thank you for this DVI Blank Screen Fix article!
    I have HP dx5150 MT desktop and a Benq G920 WL monitor and I have the same problem with a difference that my integrated vga has one D-Sub and one DVI output.
    You say: “I disconnected the D-Sub cable and the monitor loched on digital signal. That was it.”
    I would like you to ask when do I have to disconnect the D-Sub cable, while the computer is on and the Windows is running, or I have to boot up my computer connected to the monitor with both cables at the same time, shut down, and have the D-Sub cable disconnected after that?

      Hi Spirite, please help me! I work in a university and we have 90 dx5150 mt. How to configure the bios to work the two videos (dvi and vga) in the same time? Can you tell to us how do you configure your bios setup? Thanks, Julio.

    Amazingly this solution still works, three years after you discovered it. Thanks for saving all the hassles of contacting IT support.

    You could contact IT and have them try fixing it. When they would start to get really frustrated, you would fix it yourself in front of them 😀

    DVI is a great interface since it supports higher resolution video and of course more colors.`

    Write more, thats all I have to say. Literally,
    it seems as though you relied on the video
    to make your point. You obviously know what youre talking about, why waste
    your intelligence on just posting videos to your blog when you could be giving us something informative to read?

    I am having a recurrent issue with the resolution, resulting in a blank screen. I am a lab tech at a college and our IT dept has fixed this before, but they have not been in. The DVI-D is not recognized, and we do not use VGA (IT dept at school’s policies). The problem was with resolution and finding the screen off the monitor somewhere. Help me change the resolution, from a blank screen so I can get the computer running for the students in the lab please! Thanks! 🙂
