Problem displaying 2560x1600 on a Dell U3014

[Fun Guy]

So, I have a new U3014 and I am trying to get it running at its native resolution (2560x1600) on the computer I just built. The best I can manage is 1920x1200.

Here are the specs of my newly-built system:

• Dell U3014
• Asrock Z97M OC Formula
• Intel i7-4790K
• etc.

I tried hooking up the HDMI cable and the monitor did not recognize it. Then I tried the Dual-Link DVI cable with the same result - no picture.

Hooked both cables up (DVI and HDMI), then tried auto-recognize, then I finally got a picture. Looking in the display menu, the monitor seemed to like the DVI signal.

So, what's going on? What am I doing wrong??

I would think you would need a Dual-Link DVI, at least what I use on an older U2913WM (2560x1080) that has been running fine here with a 47" TV extended off the rig for years now.

Your system is newer, might just be a matter of digging into settings a bit more and playing around.

Not all Dual-Link cables are the same either, but I would think the one it shipped with would be fine if it came with the monitor.

You need the extra thick Dual link DVI cable, if you have one from an older monitor its probably not dual link (cable is much thicker).

Also what GPU? The on board doesn't support it:

- Supports HDMI with max. resolution up to 4K x 2K (4096x2304) @ 24Hz (<-- this might, not sure, maybe only @ ~48 hz) 9437184 pixels vs 4096000 @ 2560 x 1600, maybe upto 55hz depending on bandwidth
- Supports DVI-D with max. resolution up to 1920x1200 @ 60Hz
- Supports D-Sub with max. resolution up to 1920x1200 @ 60Hz

If using the on board it does look too weak other than HDMI @ 24 maybe, this one is beyond my experience.

The on board DVI-D doesn't look it will push that, yeah.

I had not considered you were trying to use on board I guess.

Use an Asus DCUII 280X TOP with the older Dell here.

Yes, using onboard 4600 graphics video for now, will get a discrete card later.

Before I got the MB I was told it would push the monitor no problem.

Unfortunately it looks like all the news will be bad news here.

Mobo max DVI resolution: Supports DVI-D with max. resolution up to 1920x1200 @ 60Hz (i.e. it is not a true DL-DVI port)

Monitor max HDMI resolution: I can't find any documentation showing that the U3014 accepts more than 1920x1080 @ 60Hz over HDMI. The purpose of the HDMI port is primarily for compatibility with consumer electronic devices, which were all 1080p at the time of the monitor's introduction. Which isn't to say that it can't be done, just that I can't find any documentation.

In theory the HDMI connection should be able to get you 2560x1600, but it's going to be on the edge. Spend a bit more time on it and see what you get. Though in the end this monitor was really meant for DisplayPort and DL-DVI.

I'm going to guess that monitor doesn't support more than 1080p over HDMI, based on my similar vintage u2713m doing the same. Either displayport or dual-link DVI is the solution.

And what bacon mentioned about the dual-link cable is correct, not all DVI cables support it, but the one that came with the monitor does.

I have a lot of experience with this monitor before leaving it for 144hz as imo 1920x1080 gaming at 144 fps and 144hz monitor refresh is a superior experience to gaming at 2560x1600 and 60hz 60 fps but for pro graphics work yea the dell is the gold standard. I Also prefer VA panels over IPS as the blacks are darker and the contrast ratio is higher and they usually have less light bleed around the edges. I find that the display seemed to work the best with display port. If you are not a gamer all you need is something semi decent to drive that. An RX460 on gtx 1050ti would be plenty for 2560x1600 work. If you aren;t doing gpu accelerated tasks.

You guys realize this post is a year old and was bumped up by a bot, right?

Haha!
Ok, closing this.
