Display Says "Input Signal out of Range" on DVI

[sirstinky]

Hi everyone. I got a Hanns G 22" monitor. It has DVI and VGA inputs. I connected it with the DVI to my custom PC with ASRock H77 Pro4 and a Radeon HD 5450. It has DVI and HDMI output. I had been running it with an old VGA only monitor until I got this one. When I connected it DVI, it worked, but the display comes out like there's no display driver. The resolution was stuck at 640x320. I uninstalled and reinstalled the graphics driver with the newest one and that didn't help. I tried changing the resolution, but it was stuck at 640 until I tried using the Radeon utility and got it to go up to 720x480. That's as high as it goes. When I tried to make it go any higher, it gives me a "Input Signal out of Range" message and reverts back the original setting. So now it's stuck at 720x480. I tried booting into safe mode, but I get nothing. I tried using the onboard video, but I still got nothing. It's only when I use the D-Sub that I can adjust the resolution. I tried to set the resolution in Safe Mode on DVI, but I get no signal.

Also, in the Display Properties in Windows, when you select the display, I see generic non-pnp monitor. When I click the "detect" button, it gives me another option from the drop down "Available display output on: AMD Radeon HD5450" when I select the HD5450, I get a list of properties that lets me choose from resolutions up to 1080p, but I can only get up to 720x480 59 Hz.

The monitor worked fine at work (I inherited it), but only worked on VGA, not DVI off onboard video. Is there a problem with the monitor? I don't have another cable to try. I have pictures, but I can't upload them here.

Thanks!

From what you tell, it is quite likely that monitor's DVI input is broken.
You could try changing the monitor driver yourself. (not GPU, monitor) since it is seen as non-pnp to see if it would work at that point.
You would need to know the maximum resolution/refresh rate monitor supports though.

Alternate solution would be to use DVI-VGA adapter on computer end and use it's VGA input which works, as you said.
Depending on DVI port on computer, it might or might not support said adapter though.

Hi and thanks for answering. I eventually surrendered and hooked it up to the D-Sub with a DVI to VGA adapter, which works fine. You could be right about the DVI having some problem, but if it was broken there'd be no output. It does seem like an issue with some kind of display adapter. The HD5450 supports full HD, so it will go up that high and the monitor is 60 Hz. I can turn the resolution all the way up 1600x1200 right now. I haven't tested it higher but will try. For now, it's good enough and looks good.

I will try to find a monitor driver for it. I know Windows does occasionally push updates for display hardware (it did for the previous monitor and fixed an issue it was having), so we will see what happens and report back.

Thanks again!

So I tried finding a display driver, but Windows says it's the best one, so I feel stuck. I even tried an HDMI to DVI adapter and ran it off the video card's HDMI, and it is the same deal with the Input Signal out of Range. I tried hooking it up to my PS4's HDMI and it does the same thing. I get a good picture from the VGA, but the DVI seems to be having issues still. Any suggestions?

Thanks.

well, windows could think that anything is the best driver (in my opinion)

Following is for windows 8.1 but you can likely adapt it to your version.
device manager
select display, right click update driver
select browse my computer for driver (not search automatically)
let me pick from list of drivers
untick "show only compatible hardware"
in standard monitor types you can select super vga 1600x1200 which is the screens maximum resolution. (or change it back to generic pnp monitor)

That should allow you to avoid screen resolution being misdetected through dvi port. If it still doesn't work after that, I would say that the port is broken for sure.
It is also possible that the monitor does NOT support 1600x1200 at all. (and it just does rescaling on vga) since I cannot find any monitors from hannsg site that would support 1600x1200 resolution: The reason might be that you never specified exact screen type.

According to this, it's 1680x1050:

Hi and thanks for responding. Yes, you are right! It only goes to 1680x1050. Now I did try to uninstall the display driver and disable it so it runs only on the graphics card, but that hasn't worked. It goes to 1024x786, but that's it on DVI. I am just running it on the D-Sub since it's working fine. BTW, being as I can only go to 1680x1050, are there any performance advantages running D-Sub over DVI?

Thanks!

In theory, DVI would be better since it is digital and thus cable length would not reduce signal quality. In practice with short cables like in desktop use it doesn't have all that great impact.
As far as performance goes (fps in games) no, no real impact at all.
As far as color quality goes, DVI would be better than d-sub but... again, the screen is old and was never really top of line as far as it's ability to reproduce colors goes, making whole difference small enough to not really matter.
I would not worry about it since choices to fix it would most likely be: Buy a new monitor. (no other choices, really)
