27 inch display problems

[GJCornish]

I bought a 27 inch Auria QWHD IPS LED Monitor for a build I'm doing. It repeated says it will put out 2560 x 1440 res.

However when I plugged it into my iMac mini display port to single DVI adapter I can only get 1990 x 1080. I called Micro Center and they reassured me that when my build is done and the monitor is being driven by my GTX 680, that I will be able to get 2560 x 1440.

I'm skeptical. Anyone ever had this problem

Your Mac mini may not have DL-DVI, or perhaps the onboard video simply doesn't support resolutions that high.

Your Mac Mini has a mini-DisplayPort?

You need to get a mini-DisplayPort to Full Size DisplayPort cable...

Like this cable here:

http://www.amazon.com/StarTech-6-Fee...to+displayport

When you get your GTX 680 the best connection for that monitor is either a Dual Link DVI-D cable or DisplayPort cable (DisplayPort to DisplayPort Cable).

I was using my friend's Auria for awhile connected to my GTX 670 with Displayport to DisplayPort connection and it worked fine.

Single Link DVI cables do not support that resolution.

For your Mac-mini plug the mini-displayport end to the thunderbolt ouput and connect the full size displayport end to your monitor's input...

Here is the tech spec for your mac mini:


Thunderbolt port with support for up to 2560-by-1600 resolution
HDMI port with support for up to 1920-by-1200 resolution
DVI output using HDMI to DVI Adapter (included)
Support for dual display and video mirroring

single link DVI is limited to 1920x1080 at 60Hz or something like that

I don't have a dual link dvi cable. Could that be it? I have just a standard single link cable. Seems like they'd furnish that. The onboard video is Radeon 4859 and drive the built in 27 inch ips led iMac screen.

Sometimes TV's may output that in every port except the one used by the computer by using a upscale system. Could that be it ? Have you seen in the manual what kind of support do they give through a DVI cable ?
About the scaling either the (monitor/TV) drivers in your computer are generic and dont detect the proper resolution or there could be something wrong with the scaling in the cpanel.

You should have gotten both a VGA cable and a dual link DVI cable with your Auria. I used the included DVI cable to run the display at the native resolution right out of the box with a 7950 and 7970, I'm inclined to say that the miniDP adapter you are using isn't sending the signal correctly.

SL DVI is limited to 1920x1200 (not really, but close enough).

Just get a minidisplayport to displayport cable; the Auria has Displayport, so no need for any messy adapters. Besides, displayport to DL-DVI adapters have always been finicky.

Okay, I'll have the new build up in a few days. I ordered a full size display prt yesterday and a dual link dvi cable. My GTX 680 has both. I don't need it for the Mac.

 

[GJCornish]

Okay, found the dual link dvi cable and ran it to the monitor from my iMac mini dv to dvi adapter. Still running at 1920 x 1048. This isn't promising and the Mini I have is an older model and probably doesn't support that resolution either. I guess I'll have to wait for the build to be completed. I have a feeling the monitor is bad and will have to go back.

Your adapter seems to be the bottleneck here, how much did it cost?

The correct adapter I think would cost close to $100. If your adapter was more like $30, then the adapter itself is incapable of running anything higher.

So no matter what the capacity of the mac's port, or the capacity of the display, that's still irrelevant if you are using a handicapped adapter that will strangle the signal passing through it.

The adapter is direct from Apple Computers. I don't recall if it was included or a later purchase.

You are not making much sense here, first you say the computer does not support the higher resolution, then you say the monitor is bad and needs to go back. I would bet that the fault lies with the Mac and the monitor is fine. I have a very new computer and my onboard video does not support my 2560x1600 monitor. When you have your build with the GTX 680 done you with be good to go.

 

[GJCornish]

No, I never said that. I was guessing at different things and have multiple computers. Anyway, I found the problem. This particular monitor, Auria, will not pull 2560 X 1440 unless you use a full size display port to display port cable. There's one on the way.

 

[PrincessFrosty]

Yeah 2560x1600 and 2560x1440 both require a DL-DVI cable specifically to provide enough bandwidth for 60hz operation, anything less like regular DVI or VGA simply won't run at full resolution.

Everything in the chain needs to be able to support it including the cable, DL-DVI cables have more pins wired in, any converters you use, the actual video ports on the graphics card and the GPU/processing in software as well. It's worth noting that even some modern video cards with dual DVI outputs might only support DL-DVI on one of them.

Last LAN party my friend used my 2560x1600 panel and we wasted 10 minutes working otu why his ATI card wasn't displaying, it's because while it has 2 DL-DVI ports on the back it only supports full DL-DVI across one of them.
