I assume you're using AMD as I have had issues with refresh rate dropping back to 60 for no reason occasionally. Seemed to be resolved for me by setting refresh rate through Windows display properties instead of Catalyst Control Center.

If you're using Custom Res. Utility to set your OC timings you can also try deleting the original 60hz profile. It can't downclock if 96hz is the lowest profile available.

nvidia. 780ti. and i just made a custom profile through nvidia control panel for the 96. deleting the 60 hz profile sounded like a good idea. i couldnt do it though. unless im missing something, it wont let me do it.

Just received the used QNIX 2710 from an ebay seller. I have to say that i am very underwhelmed with the colors,they look bland almost no better than my asus vg248qe. I don't think this was an 07 model either because this was a QNIX with the old eye logo manufactured in 2013 before they used 07's.

Are ICC profiles mandatory in order for the monitor to look good?I might give it another chance after i buy a DVI cable otherwise i may return it.

Why the hell is it coming out analog? And why does it magically work without nvidia drivers? I have quite a few questions now. I don't know how to change edid information so that it appears as DVI nor am I sure that it is even possible or the problem. The seller said they would ship me a new board, I'm just afraid that if it doesn't work, it's a problem with my gpu. I'd be happy accept any advice anyone has, thanks
I received the board from them and tried installing it. I think they actually sent me the wrong board, because a slot is missing and one of the connectors doesn't fit. Lol, this has been one of the worst decisions I have ever made. I'm going to send the monitor back and probably pay out the ass for a return. It's unfortunate I'm alone with this problem seeing as how no one could help me. I'm out of the club I guess in search of greener pastures, peace.

Hey guys,

will this one overclock at all? i read that new versions of qnix does not overclock so i just want to make sure before my purchase.

Only single input DVD-DL Qnix overclocks. If it has HDMI, it does not.. or OC's very poorly with frame skipping.

As I'm sure a lot of you have noticed, the X-Star DP2710 Dual-DVI monitor features a broken EDID block.

This is my attempt to work around the issue on Debian 8 with Intel Graphics:

The problem:
You get messages in dmesg:

This can cause all sorts of strangeness with Xorg and WMs.

So what's wrong?
Code:
# get-edid -i -b 6 | edid-decode 
6
This is read-edid version 3.0.1. Prepare for some fun.
Attempting to use i2c interface
No EDID on bus 0
No EDID on bus 1
No EDID on bus 2
No EDID on bus 3
No EDID on bus 4
2 potential busses found: 5 6
Only trying 6 as per your request.
128-byte EDID successfully retrieved from i2c bus 6
Looks like i2c was successful. Have a good day.

With the help of 'wxEDID' and a hex editor, I was able to produce this:

Now I realize 'edid-decode' still thinks there is something wrong, but I'm pretty sure thats a bug in edid-decode itself?

This is how I'm using it:

In case you are wondering, why am I using DP-1 for a DL-DVI device. The Dell BizLink DP->DL-DVI-adapter.

Now it's working much nicer for me:

i've always had this problem, i hate it too.

if i move a simple browser window or something to the 60hz display, my qnix @ 110Hz stays at 110.
but once i move a video to the 60hz display, everything on the qnix slows down to 60 FPS. it's still 110Hz though.

i ended up just replacing it with a fast display... not the way that it should be, but i just did it.
