Can you please look REALLY closely and check whether you have panel uniformity issues at higher than 96Hz? Use solid color backgrounds if it helps.

A few weeks back, I had the impression that most / all of those who were cranking the high overclocks were suffering from:

1) Panel uniformity issues

2) "Darkening" which is a gamma shift that can easily be corrected by software color calibration (I suppose it happens with 100% of users)

3) Image retention which was happening as a result of an image staying on the monitor for a good amount of time (I remember some reporting IR when they didn't expect it though) (I suppose this happens with 100% as well)

I am mostly concerned with the 1st, as the other two are not much of an issue (the 2nd can be corrected, the 3rd can be avoided)

Cheers!

Panel uniformity can be lightened at custom timings that overall lower the pixel clock. Mainly the total pixel count.

I will add a section to the OP FAQ about recommended GPUs, with emphasis on vram sizes. 2gb is recommended for gaming, while anything below that is fine for just using the monitor for non-gaming purposes right?

Absolutely. You could run 1440p with system integrated RAM if you had a built on DVI-D port. The 2GB of RAM is for texture filtering size/storage for processing. 2GB is essentially needed for the data size that 1440p size of textures takes at any given time. This would not effect anything outside of gaming or HD rendering with madvr.

EDIT: With NO AA on. If you plan on having 1440p and want all kinds of AA on(which is a bit useless for most but can help if you really want to) then you will need even more VRAM to store the filtered textures.

You could also include something about the 700 series and titan cards not having a pixel clock limit.

The OP didn't answer the video card question. It didn't answer how easily overclocked it is. I'm wondering what problems people have had, etc. Looking for personal experiences.

It's ok, though. I'm sorry I offended you for asking the question. My question remains open, though. That's what the forum is for. If anyone can provide me with some of their experiences with this monitor, it would be appreciated.

If you read the first post, there's an entire Google docs list of people and their experiences with their monitors...

Yes, and thank you for the ad hominem yet again. +Rep to those that actually helped.
In progress.

1) Minor if there. The slight BLB around the edges is more of a problem, neither are visible unless you look very closely.

2) Unavoidable, my gamma went from 2.5 to 3.3 after going to 120Hz. Fixed to 2.2 after I calibrated it.

3) I get very slight image retention of my top bar, but it goes after a few seconds. Is only visible as a slight lightening of the top few pixels, if you are looking for it.

For reference, I'm using a custom-made ICC profile on a 120Hz X-Star Matte. AMD 7870 Tahiti LE. CRU profile is LCD Reduced with a refresh rate of 120Hz.

I ran a 1GB HD7770 for a few weeks with this monitor, did all regular tasks perfectly. Most taxing thing was probably video playback, and I didn't have any problem with memory.

3GB minimum if you want to buy a card that'll last a few years though.

hey guys, so some games are fine with 100hz but some games aren't.

for some reason some games still cap at 60fps. i have adaptive vsync on. should i just turn that off and will it display 100fps to me??

some games that show only 60fps:

cs:go
mortal kombat
street fight x tekken
dota 2

i am using the evga precision x + CRU method of overclocking.

Turning vsync off will NOT get you a actual higher framerate. You will be just running 100fps at 60hz. That is the difference between HZ and FPS. If you have this set in CRU you need to set your 3D settings in NVCP to preferred refresh rate to "highest available. I posted this a few pages back with some screen shots. You may need to re-install your drivers for the option to show up and if i remember correctly it may need to be 120hz for it to show up. Aside from that you could try installing the catleap 120hz driver and that may help you.

To find my post search force refresh rate in this thread.
