Pretty sure I wrote a few things when I bought it a couple months back.
Beautiful display, but there really isn't OS support for this size yet.
To make it useable you have to enable HiDP mode then it becomes a 1920x1080....so like a 24".
Windows has a better grip on this but causes certain apps to crash.
The biggest issue I have with the Asus is the INSANE, RIDICULOUS set of button pushing to go from SST to MST.
Whoever came up with the sequence needs to be taken out and shot, now. BEFORE a last meal and/or cigarette. It's like the safeguards you would expect before opening an airlock in a space station. There are 7 buttons down the side which you have to pick out by feel. There is a feeble label you can stick to front of panel, but nearly worthless.
There is no space between groupings of buttons so you need to be very certain.
To switch modes it is (1 on top, 7 on bottom):
6 - selects OSD
5- moves down to "setup"
6 - moves you to options, top one is "language" (can't tell you how many times I've switched into Chinese)
4 - 1 time or 5@5 times to cycle to "DisplayPort Stream"
6 - to select
2 (or 3) to change to MST (or SST if you were in MST)
5 to got to "set"
6 to enter ----this takes you to "To enable, must restart, restart now?"
2 or 3 to switch from default "no" to "yes"
6 - one last time to enter
I am not exaggerating, it is the most insane bunch of invisible button pushing you will ever do. Most people won't do this much, but for testing video cards.....very frustrating.
Sadly, for cMP with cards that support this, boot screens in Windows don't show up in MST, sometimes OSX does on half screen. So if you need to see them, you need to switch to SST. If you then start gaming in Windows and everything is all jerky jerky, you need 60Hz. Decide to go back to OSX, better switch before reboot. Decide to see what OSX cards do 60Hz? repeat the 10 button push tango.
You end up frequently looking at a black display, trying to decide if you are up to the crazy sequence to find out if OS crashed or just in wrong setting.
Why this couldn't have been a 1 or 2 button thing I will never understand.
If you think you will need to switch much, avoid the Asus / Sharp twins. A few OS switch reboots mixed with whiskey and a handgun could lead to tragedy.
