sooo, I'm getting 3 ultra wide LG monitors for Xmas, and was wondering if my GPU was up for the task? the only problem is... it has this DVI-D socket, and I tried running a VGA adaptor on it before and it didn't work.

I was wondering if there is an adaptor out there for DVI-D to HDMI or DP with supporting an ultra wide with the resolution 2560 x 1080. I'm stuck looking for one, and people say to get an active adapter? I'm so confused, please help!

if my GPU can't run the monitors is there any way around this? get another r9 390? or a new GPU? and which new one shall I get? GTX 1060?
Thanks for any replies!

Too bad the 390 doesn't support HDMI 2.0. I would use the two DVI-D ports and one DisplayPort to DVI adapter.

I've never used crossfire but I do have experience with Nvidia SLI. SLI works fine with multiple monitors but all of the monitors have to be plugged into the same GPU to do that. I assume crossfire works the same way.
What inputs does the monitor have? If it has DisplayPort you don't need any adapters. If it only supports DVI-D you need DisplayPort to DVI adapters. I doubt there are any ultrawide monitors that only support DVI-I so you shouldn't need to worry about getting an active adapter.

It looks like most 390s have one DVI-D port so you will need one 3 DVI-D cables and 2 DisplayPort to DVI adapters. Like I said though, if the monitors support DisplayPort you shouldn't need any adapters.
 
Sorry, it has 1 HDMI 2.0, 1 DVI-D, 1 D-Sub.
And my GPU has 1 HDMI, 1 DP, and I think 2 DVI-D

so I guess I could do that, is it worth running off both the DVI's or running on DVI and one DP?
plus I could save up for another r9 390, is that worth it? run 2 monitors off the second and then my main on the first? I'm new to this haha.
and would the crossfire work with these monitors? cause it never did when I tried it with the 2 i have now which are not the ultra wides.

Well the reason I said that is because I read that HDMI 1.4 does not support 21:9 resolutions which is what your ultrawide monitors are. Supposedly 21:9 was added in with the HDMI 2.0 spec. Now that I have done a couple more searches I see that some people are able to get 21:9 working over HDMI 1.4 even though it isn't technically supported in the spec depending on which monitor you have.

So, HDMI from your 390 to your ultrawide monitor might work or it might not. You could always just try it and see before you buy an adapter. This is the same reason I wouldn't recommend an HDMI to DVI adapter. If HDMI doesn't work directly connected to your monitor it probably won't work through an HDMI to DVI adapter either.

DisplayPort has kind of become the standard for monitors. It has the most bandwidth and was the only way to get things like G-Sync, FreeSync, and 4K 60Hz to work but HDMI 2.0 is also able to do everything but G-Sync now. DisplayPort was also designed to be backwards compatible with HDMI, DVI, and VGA through adapters. This is why most of the new GPUs from both Nvidia and AMD have 3 DisplayPorts, 1 HDMI, and 1 DVI port while many older cards had more HDMI and DVI ports.

The adapter you picked should work fine. It looks like you will be able to connect either a DVI or HDMI cable to the other end of that DisplayPort adapter and get the job done.
 
Thanks, soo much for the help, ill buy that one and see if it works. I'm sure I can do the ultrawide monitor over HDMI as a friend has, yet I'm not sure if I can get the same results with a HDMI 1.4, but ill keep in contact to show my results!
Thanks again.
 
Yeah, if your friend has an Nvidia 900 series, 1000 series, or AMD 400 series card it supports HDMI 2.0. Unfortunately the AMD 300 series does not. Like I said though, there were some people on Reddit saying 21:9 worked on their monitor over HDMI 1.4 even though it isn't actually in the HDMI 1.4 spec. Good luck.
 
so, it turns out that the monitor has 2 HDMI ports and no DVI-D, even though they said it did on the website. so do you think I could get a DVI-D to HDMI adapter to work with it?
 
soo the problem continues, i have 2 monitors on 21:9 setup on the DP to HDMI and my HDMI outputs, but the DVI-D can't see to get to work, I used an adapter that sai dit supports up to 4k resolutions but the output only goes up to 1080p its the same with another adapter I got today. do the r9390 DVI-D outputs not work with above 1080p resolutions or am I selecting the wrong adapters?
 
That's rough. Since you GPU only has 1 DisplayPort and 1 HDMI port I'm not sure what you can do if the third monitor won't work with a DVI-D to HDMI adapter. The only thing I can think of is to return the 3rd monitor and buy a new one that supports ultrawide through DVI-D natively. Of course, all your monitors won't match then.
 
For CS:GO you probably can. For most other games it's not going to happen. Most 1070s have 1 HDMI 2.0 port and 3 DisplayPorts. Some of them have 2 HDMI 2.0 and 2 DisplayPorts. Just keep that in mind when you are buying your cables and adapters.
 
or I could get the RX 490 when it comes out, I've read it comes in January but how much would it be roughly? if too much do you think gtx1060 could do 3 ultra wide monitors with csgo?
 


It's hard to say since the RX 490 hasn't even been announced yet. Just going from last generation where the R9 390 competed with the GTX 970 in both price and performance I think it will cost about as much as a 1070 with similar performance.

I'm really not the person to ask about gaming on triple monitors because I only game on one. My second monitor is only used for web browsing and music control. CS:GO is not very graphically demanding so my hunch is that you would be able to get at least 60 FPS with a 1060 but I don't know for sure.

7680x1080 is the same amount of pixels as 3840x2160 (4K). The 1060 and even the 1070 are not really 4K cards so most games are not going to run well. You can look at 4K benchmarks to see what kind of performance to expect. My guess is that most games aren't even going to support 7680x1080 but I've never gamed on multiple monitors so I don't really know how much support there is.

I would not bother getting a 1060 unless you are only doing it to support your 3 ultrawide monitor setup. It is not really an upgrade from your 390 since both cards have about the same level of performance. The only real benefit you would see is that you would have enough DisplayPort and HDMI 2.0 ports to connect all your monitors.

If you only play CS:GO then sure. Like I said, I would not buy a 1060 if I owned a 390 though. They perform about the same. The only reason to do it is to get the ports you need for your 3 ultrawide monitor setup.

If you only play CS:GO you should be fine but if you want to play more demanding games at 2560x1080 the 1070 will do better. It is also an actual upgrade from your 390.
