AMD Eyefinity Messed Up My Monitor Setup

Havenost · Feb 1, 2016

So I have dual monitors. So today I decided to go tinker around with AMD Eyefinity with the latest Radeon 15.12 Crimson drivers. Needless to say I got it to work.

So afterwards I disabled Eyefinity because my two monitor sit quite a distance away from each other and its pointless to have two different monitors project as one monitor if there is a giant gap in the middle of picture.

I decided to go watch a movie afterwards and noticed while in full screen that there was screen tearing. A problem that is caused by having your screens on "extend" mode... so I hit windows key + P to switch my display mode back "computer only". But when I do that, now my main monitor won't work. I get blank screens with an error message that says "Input device not supported".

I have been using the windows key + P display options for 4 years now, and I regularly switch between them with no issues till today after using Eyeinfinity. Does anyone have a fix for this issue? Anyone know what the heck AMD Eyeinfinity did my settings/monitor to make it not work anymore?

It sounds like your monitor situation is sub-par. Generally you need 3x display port monitors for eyefinity.

damric :

Did you bother reading the actual post? The issue is not with getting multiple monitors to display one image. The problem is when I reverted back to my normal set up as in after I DISABLED Eyeinfinity, I can't use the "computer only" display option in windows 7 anymore. The "computer only" is the same as right hand clicking on the desktop pressing "screen resolution" and choosing the option of "Show desktop on 1" in the "Multiple displays" drop down list.

He is actually correct. Eyefinity only works with 3 monitors, not specifically DisplayPort but 3 or more monitors. When running two monitors it should just be a normal desktop extension. Not sure how you got it to work beyond that because again Eyefinity specifically is tailored for 3 or more monitors.

What we need information wise though is what ports are your monitors plugged into and have you tried running just a single monitor to make sure there are no issues with the GPU port or monitor?

Havenost · Feb 1, 2016

Once again the issue is not getting Eyefinity to work. It already works. The issue I have is it did something to one of my monitors so that it can no longer work by itself altogether.

I have a Acer S201HL and and a Acer G206HL. They are both hooked up through DVI-D ports to an R9 390. Both of them were working perfectly fine until I after I experimented with the Eyefinity which I have since then disabled. They work perfectly fine with Eyefinity.

The issue I am having here is for some reason whenever I try to use the Acer G206HL by itself will no longer works and says "Input Is Not Supported". If I unplug my S201HL, the G206HL stops accepting input for some reason. Or if I plug in my S201HL and try to only use the G206HL, the G206HL still has the same problem.

The S201HL still works by itself without a second monitor. So Eyefinity did something to my G206HL's drivers or firmware that is preventing it from working without a second monitor.

Also Eyefinity works with 2 monitors as you said, it doesn't do anything except extend the image across 2 monitors which is exactly why I disabled and don't plan to use it after seeing that was all it did.

Also all I did to get Eyefinity to work was

1. Open up "AMD Settings" program
2. Clicked on "Displays" tab
3. Clicked on "Additional Settings", which opened up the leftovers of AMD CCC
4. Clicked on "Create AMD Eyefinity Display Group"
5. Basically pressed next 3 times, since I only have 2 monitors, so there wasn't any real reconfiguration I could do other than choosing if I wanted Eyefinity to work in portrait or landscape.

That was literally all I did. Then I saw the results of just extended desktop across 2 monitors, and hit the "Disable AMD Eyefinity Display Group". And found the issue with my G206HL no longer being able to function without a second monitor.

jimmysmitty · Feb 1, 2016

The whole idea behind Eyefinity is to be able to use 3 monitors to make a bigger image. 2 is, well 2 is just a weird number as most games don;t work well with two since it centers the game on the bezel.

That said, I suggest you uninstall the driver, then use DDU to clean out the driver and reinstall the latest driver. Maybe something has gotten stuck in the configuration.

Either that or coincidentally one of your ports decided to go bad.

Havenost :

Jimmysmitty is right and I'd suggest uninstalling and reinstalling the graphics drivers using the DDU. I've seen eyefinity settings mess things up once you've returned to a standard display configuration before.

Aside from that, these guys are correct in their arguments that eyefinity is not, and has never, been intended for use with less than three monitors. Same thing applies to Nvidia surround. There are however utilities intended for creating a single unified display using two monitors, but it doesn't sound like that's something you'll be wanting to do anyhow so I'd just reinstall the drivers after removing them with the DDU.

Havenost · Feb 2, 2016

Darkbreeze :

As Jimmysmitty pointed out it was pointless because of the bezel right in between the monitors. I wasn't actually trying to make use of the Eyefinity, the only reason I even bothered to tinker around with it was just for the sake of curiosity. I wanted to see what it was, and how easier it would be to set up. I obviously found out what it is, and found it extremely easy to set up.

What I got was an unpleasant surprise the Eyefinity broke something with my monitor's driver. Even after uninstalling AMD Drivers and manually deleting AMD registry keys, and even installing AMD's recently released beta 16.1 drivers the problem persist. I even used DDU to uninstall the drivers as suggest and the problem persist.

So far after all of this what I have learned is the monitor is in no way dysfunctional since the G206HL works by itself when using the generic Microsoft Drivers... its only when using AMD drivers that it seems to have some weird permanent compatibility issues after using Eyefinity.

As for the whole issue whether Eyefinity is meant to be used with at least 3 monitors, its a non-issue. I don't dispute that matter and agree with notion that it is pointless unless you have 3 monitors. But the point here is it has nothing to do with the problem so stop bringing it up because it pointless derailment.

Darkbreeze · Feb 2, 2016

It's not pointless, because you did in fact attempt to use it with only two monitors, which is what broke your configuration settings. But whatever. Good luck.

Havenost · Feb 3, 2016

Darkbreeze :

That is absolute hearsay, and not a single bit of deductive evidence to back that up.

Yeah its pointless to use Eyefinity with 2 monitors in the particular scenario that I am in but no where is there any indication that 3 monitors are required. If I had larger monitors that weren't wide screen, then there would be plenty of good use case scenarios for Eyefinity with just 2 monitors.

Also the fact Eyefinity works perfectly fine with 2 monitors completely disproves your point and it still works if I turn it on.

The only thing that is known here is the fact something in AMD Eyefinity drivers messed something up in terms of driver compatibility after it was activated. It has done no phyisical hardware damage considering the fact that the monitor works on other drivers, when plugging in the currently problematic monitor into other system, it also works fine.

So its obvious the issue is something with AMD changing Windows settings improperly, rather than the lack of monitors.

After reading this thread

http://www.tomshardware.com/faq/id-2003616/eyefinity-setup-guide.html

I am going to guess the issue is caused by the fact that I don't / didn't have a monitor connected to a Display Port rather than lacking a sheer amount of monitors since both of my monitors are hooked up through DVI-D rather than a Display Port.

Which would make sense on why I am not getting any display when I go back to "Computer Only" (in Windows 7) or "PC Screen Only" (in Windows 10) because either

1. AMD Drivers thinks my primary monitor is hooked up to the Display Port on my GPU and is sending all the info to the Display Port rather than the DVI ports.

So my theory to fixing this problem most likely is if I simply plugged in a monitor to the display port, then go into Windows and tell it to chose one of my other monitors that are hooked up to DVI as the main monitor, it will fix the issue of "Computer Only" option not working. Sadly for me I don't have monitor that is capable port capable to test this out.

2. AMD Drivers reconfigured my G206HL monitor into thinking it is a Display Port Monitor when in reality its a DVI or VGA monitor.

Which I have absolutely no idea on how fix because I am unsure how such a thing like this even happens. Though to be honest I think this is the real problem right here.

Havenost, I'm trying to Pm you, but won't work as I'm a brand new member. Did you ever find a solution? I made the exact same "mistake" you did. Not to keen on asking the same question just to get battered for being an "idiot" for trying it on two monitors

discord37 · Aug 27, 2016

I just made this silly mistake yesterday and I'm past full of regret. My now no signal 2nd monitor is my living room TV and I don't have cable, all my TV comes from my computers.

I was poking around to see what it did, I have 2 monitors, I wasn't going to use it, and I now see it doesn't work well with 2 monitors but changing this setting (by mistake) should not ruin ones computer for good. I found this post before I removed & reinstalled the software so I haven't done that yet, but I did try setting everything in in the Radeon settings to default and tried reverting my PC back to earlier this week where I had a restore point but it didn't fix it.

For the people who think those of us who screwed this up are stupid, if you read the info in the software to set it up it says nothing about 3 monitors, it only says multiple which I'm pretty sure includes 2.

NORpc · Aug 27, 2016

I figured out what caused this for me at least. Might be different than for you, but try adjusting the monitors hertz. When I used eyefinity it changed the native hz on my primary monitor to 22hz or something. For you, maybe it changed the hz of your TV to the extent that it cannot deal with it, and just doesn't show anything.

discord37 · Aug 28, 2016

I'll have to check that. I don't know what they originally were but both monitors are 60 now which sounds right?

JakeAGuest · Sep 12, 2016

Just did the same as everyone here! Found the solution (atleast for me). I went and just updated the Radeon Settings. I had 2 updates waiting and after installing and restarting, I then clicked Widnows+p, changed to extended and now it's fixed.

I don't know what the problem was, but that's my solution.

Havenost · Sep 21, 2016

I am looking at the current stable 16.7.3 change logs and they acknowledged some problems with Eyefinity though they didn't say fixed it yet.

"Displays may fail to revert to previous configuration on exit when using a profiled application launched with Radeon Settings and “Launch with AMD Eyefinity” toggled on."

So did you install the beta drivers?

I did clean install of my drivers, and I even had a clean install Windows 10 to see if that fixed anything... it sadly did not. So at the moment I just always run my monitors on extend mode because my G206HL still won't work by itself.

JakeAGuest · Sep 21, 2016

Havenost :

Updating fixed it once, then I rebooted and the problem came back. I tried again and I used guru3d gpu driver uninstaller to uninstall everything, then reinstalled 16.6.2 and it fixed everything. I didn't do any more than that. Uninstalling the AMD driver reset everything and reinstalling fixed it. It was a very simple fix for me. I hope this helps somewhat.

Havenost · Sep 21, 2016

Huh, sadly that didn't work for me. I have done it a couple of times already. Plus I am currently already on 16.7.3.

I also even tried the underclocking / overclocking method. Didn't work either.

Havenost · Sep 24, 2016

So apparently after turning on and off AMD Eyefinity today my second monitor now works by itself again. Guess AMD finally fix the issue with the broken driver.

The mistake I made after installing multiple more up to date AMD drivers is that I never tried toggling AMD Eyefinity on and off a second time around.

It really didn't have anything to do with not having 3 monitors.
