U2414H Resolution problems - Getting the run around with Support. Help!

Question

I am one of the many who is currently now experiancing resolution issues and signal issues with my3x u2414h REV00 monitors.

I have found forum threads across the web showing alarming evidence of these issues including this very forum.

U2414H DisplayPort Daisy Chain/MST Resolution Issue
en.community.dell.com/.../19563839

Will there be a firmware fix for U2414H DP issues?

Builders Beware: Overwhelming evidence that all revisions of Dell's U2414H monitors are defective from the factory. Does not work with DP 1.2 reliably in any configuration.

However from the advice of Dell reps given to others who are having these issues - they have recommended getting the monitors reaplced.

But when I contact support (Australia) I am getting the run around. Saying it is not their issue. They justify this by explaining that when each monitor is connected individually, they work perfectly. I have sent them links to the many theads explaining that their logic is false and that the main issue is the MST functionality. But i still get no where.

It has gotten as far as the Dell reps requesting that i take it to a entertainment store (BestBuy equivilant) and asking them to troubleshoot it (no i did not buy it from them, no i have no dealings with this company and yes of course they declined when i asked - just to satisfy the rep)

They also suggested it was my GPU (Asus HD7950-DC2T-3GD5-V2) simply did not have enough bandwidth to power 3x moniors at 1080. Correction it does and has been doing so since i bought it April 2014 but suffered constantly from signal failures, unable to wake up from sleep, and resolution issues where the monitors were stuck in 640x480

And now they have recently requested i take photographic proof of the way i am connecting these monitors to my system. To which i have provided.

I just want this resolved and am asking the community (or any other Dell reps) to give me any suggestions. It just seems that Dell Australia refuse to acknowege the issue.

No advice from anyone?

There really isn't any advice to give unfortunately. The monitors are broken with regards to MST\daisy-chain functionality. Dell isn't going to admit it, and they've said straight out that no firmware update is forthcoming. The only thing you could do is try to get them set up without using daisy-chain. I'm not sure what ports your 7950 has, but if you've got 3 digital outs of any kind (DVI, HDMI, DP) you could use adapters to set all your monitors up in parallel rather than serial, so to speak. EDIT>I just looked up your card. Looks like you have 1 DP port, an HDMI port, and two DVI ports, one full and one digital only. If that's the case, use one DP cable for the first monitor, an HDMI cable for the second monitor, and a DVI-D to HDMI cable for the third monitor. Should have no issues after that.

The MST issues with Nvidia were mostly driver faults. Several users ended up trying multiple drivers before finding one that worked. They ended up going to an OLDER driver. For AMD, not much traffic. Assuming you have the latest AMD reference driver and Catalyst Control Center loaded? Have you tested older AMD drivers?
