Display not coming online after idle - unless I TeamViewer in

[Formhault]

So... I just got a new GPU (Sapphire R9 380 Nitro OC, 4GB DDR5, all that goodness), and this just started happening...

 

I leave my PC on, I turn the monitor off and I leave the house. Several hours later, when I return... I fire up the monitor and I have no image. I must use my phone to remote in via TeamViewer first.

 

I have no idea why, but I suspect it is the new graphics card / software (Crimson driver)? I previously had a Gigabyte AMD Radeon 6870, with the old Catalyst Control Center (14.7, since 15.2 or whatever the newer one was HATED Xonotic - some old "triple A" title game I play - and would crash every time I minimized the game). Also, the video signal comes out of the GPU via a DVI output, then a DVI to VGA adapter, then goes through a VGA cable to my monitor... because of this. But with the old GPU, this adapter setup worked fine - could it be that the new GPU doesn't like the adapter so it idles or something...? I don't think so, but oh well, mysterious are transistors' ways?

 

Here's a video I made to better explain the whole situation. I filmed it with my girlfriend's OnePlus One, and I believe it was set on slow motion 60fps from before... also, I realised it's out of focus only some 15 seconds in.

First of all, please buy a proper cable, why ruin those gorgeous graphics with an analog cable? Do you have any power saving features for your keyboard/mouse that will turn them off if the display is off? I had an issue where my razer keyboard and mouse wouldn't wake my screen because they were set to turn off when the display wasn't on.

His monitor flickers when DVI is plugged in.

...Well that's not supposed to happen >< sure it wasn't an analog DVI? Sounds very much like a analog problem IMO

My mouse (no-name, $4 from eBay - better than anything, imo ) and keyboard (10 year old Apollo, won't change for anything) are just fine. No wake settings have been changed... Just the GPU...

 

Also, I have 3 DVI cables. Please read the story I linked to in the OP, it's really interesting...

Well, I dunno. The monitor, with my DVI cable (which worked fine with my old monitor, but not at all with the new one) worked fine at the store when I went there to show them my problem. But... the monitor doesn't work with two DVI cables at my house, on both my computers, and now with this new GPU, so it's not the system... nor the cables... I dunno...

 

So far, DVI to VGA seems fine. How am I killing it? I honestly don't see any difference. Also, when I went from VGA to DVI (didn't realise my old monitor has a DVI input as well) on the old monitor, I didn't see any difference. Been using it for 4~5 years with VGA, then some more years with DVI... no notable difference...

Depends on what kind of DVI output is on your GPU, what DVI cable you're using and what DVI input there is on your monitor... I think there are 5 different DVI configs

What...?! 5 different DVI configs?! Jesus!

 

Okay, I'm open to suggestions. If you can help on this matter, please chime in in the other thread. I'd be grateful

Yeah 5, I have included an informative slide.

Thank you! I'll get back at this when I have more time & look at the cables & ports. But all I know right now is this : the cable is DVI-D (Single Link), and it worked just fine on my old monitor... it also worked just fine at the shop.

 

Why was it working fine in one place, but not in another? The monitor is the same, the cable is the same... I also tried both ends of the cable - they are both the same, anyway.

 

Could that be the culprit...?

Did you use your own computer at that shop aswell?

[Formhault]

No... Of course I did not carry the computer with me as well. Lol. A monitor should work anywhere, right?

 

So far I tried with a Gigabyte 6870 (my old GPU), this new Sapphire R9 380, my parents' PC (NVIDIA GeForce GT 7300)... and the output has been the same : blacks are blue, whites are yellow, you can see "buzzing" lines all over the place. At the store, it worked fine. WITH MY CABLE. Is this monitor REALLY THAT NEEDY and it only likes SOME graphics cards?! As far as I know, there's no such thing :\

Oh and as for the initial issue of this thread... display not coming on after several time in idle... I think this is due to the GPU - it enters some deep sleep or God knows what, this Crimson driver most likely has rough edges, so...

Yeah, so I can CTRL+ALT+DEL to regain image, as well. All it needs is a little push from the back... the GPU, I mean.

So if your cable is analog and those connectors are digital, it seems unlikely, but you know. Check the documentation what cable are you holding in your hand and what cable are you supposed to be using

From what I remember, the cable is either DVI-I Single Link, either DVI-D Single Link. While the ports on the GPU are DVI-I Dual Link. Could that be the problem?

 

The ports on the old GPU were also DVI-I Dual Link, and the cable Single Link, and the old monitor worked fine... I'll have to get a DVI-I Dual Link cable, I suppose?

Ideally what you want is a DVI-D dual link if your monitor supports that. The problem might be the cable, what monitor is it?

It's a Samsung S24C200.

 

I ordered a DVI-D dual link cable from eBay. Was 9 USD. Should do the trick - hope it does. Otherwise, I may have to go to that expensive electronics shop where such a cable is 15 USD or so -.-

The quality of a digital cable has very little to do with this, either it works or it dosen't. In very rare cases it might act up because reasons...
