post #6641 of 25943
Haven't been able to OC my monitor any higher than 70hz without getting intermittent horizontal lines on my screen whenever I would move windows. Is there anything specific you guys do? I have a feeling that it has something to do with my video card (5850) or drivers (13.4).

There are a lot of new products that will make it possible though(HDMI 2.0, SSDs, Maxwell series GPUs, etc) but they are just not here yet. Even a Titan GPU can have problems rendering some games at 1440p and maintaining 120fps(much less 241hz for people who like to frame double to reduce input lag to visual association). Until GPUs and other hardware get to a point that i can double my framerate per my refresh at 1440p i will likely stay put. Also many 4K variants so far do not offer the color reproduction benefits of PLS and IPS displays. This is what makes the Qnix such a future proof display. It is just going to be a long time before anything over 1440p will catch up in specs and more importantly price.


EDIT: This is why if a 4K@120hz will likely not show up for a while until other factors of hardware catch up to be able to support it (Display ports might be able to do just over 60hz depending on the PCB and controller board).

Yes very true which is why it will probably be dual controllers.

Can you point me in the right direction?

I made a video nothing special explaining how to overclock with an nvidia card. Check my post and also make sure your card is compatible.


Anyone looking to purchase one of these monitors. I ordered from MNW GLOBAL on Amazon.( Amazon backs the warranty with A to Z protection with this seller) Once the package shipped it took one day to arrive. As previous people here said before, it's pretty much a waste to buy pixel perfect. My monitor has no dead pixels and I did not order pixel perfect, I simply contacted MNW GLOBAL ahead of time and asked to send a monitor with no dead pixels or backlight bleeding... What I got was a perfect pixel monitor with BAD backlight bleeding lol....... but for 300$ shipped... a 2560x1440 monitor that can overclock... I was more than happy to fix the backlight problems. I am not sure why anyone would buy these monitors without a protection plan or warranty.



To anyone that might be seeing display driver stopped responding message. I get them rarely but I am not sure if it's do to overclock or being the drivers(Beta). I've had it happen in Skyrim sometimes, the screen goes black and the blue led blinks a couple of times but then comes back on. It doesn't happen too often and is not a big inconvenience but last night I did get a driver stopped responding message. This could be due to the fact of an overclock(unlikely) I think its a driver related issue being that we are running in test mode and patching the current driver. If anyone knows anything about this let me know.

If you patched everything properly and used CRU correctly, it'll be either
a) GPU
b) Cable
c) Monitor (very unlikely).

Also: what pixel clock does CRU show with your settings? Spartan may be able to work something out from it. (with all the research he's done).

Do you/friends have any parts you could test with? Also try CCC>My Digital Flat Panels>Properties and see if the two "DVI Settings" help at all.

Cables - 24AWG vs Length
Timings - CRU/NVCP, Manual vs auto/reduced_search "front porch"
Drivers - GPU/Monitor/full vs partial install
Ports - GPU per port
Overclocking software - CRU vs NVCP vs EDID hacking

Search please. The specifics are littered all over the thread and have been repeated often(roughly 2-3 times per 50 pages)

You beat me to it rolleyes.gif

EDIT: If you are having issues overclocking and have tried all the "easier" testable options listed above posting a screenshot of your timings is going to be best.

EDIT2: Also is it ONLY when you move windows?

Lol, I'm just as surprised.

That standard list looks good, but 70Hz seemed weird - it's not the typical "I OCed to 120Hz straight away and got weird stuff" question.

rusky1 - what happens if you try something a lot higher - say 100Hz? And just to confirm, you are running the DVI-D only model off straight off a DVI-D cable? If so, how long is the cable?

The CCC DVI properties don't help, although reducing DVI frequency seems to make things marginally better.

Cable: I have the stock cable that came with the monitor and a thicker (not sure what gauge) gold plated one.



Timings: See picture above

Drivers: I followed the guide. AMD 13.4 Drivers using the amd patcher 1.2. There was no test-mode.exe file used though.

Ports: Using a single 5850 (first 16x slot), plugging the monitor into the DVI-D port. Monitor is single input only.

OC software: CRU

My thoughts exactly. I wasn't expecting 120hz, but I started questioning things when even 80hz had the tearing. I tried several different refresh rates, 80, 90, 96 , 100, 110, and 120.

Are you able to borrow a GPU? My 7770 1GB ran 120Hz, so perhaps it is to do with the age of the card.

Only other *possibility* and I'm throwing this out there, is that your PCB is different/really broken. Not sure how/why this would be the case though, and it is, again, highly unlikely.

EDIT: A quick search for "5850" brings up this post: http://www.overclock.net/t/1384767/official-the-korean-pls-monitor-club-qnix-x-star/1990#post_20048057
So I'm definitely leaning towards the idea it's a GPU problem, fortunately for you Hawaii is out soon, and 7950's are going cheap wink.gif

Quick update!

Looks the the problem was with my GPU OC settings. I had it clocked at 880/1180 which resulted in corruption. As soon as I reverted all clocks back to stock, the problems went away. Thankfully I only have to wait another month or so before the 9970 comes out, I hope it won't be plagued by the same OC problem.

I've now been able to OC to 120hz without any issue.

This is the backlight. So either you broke it or you accidentally plug off the power

EDIT: Fantastic you figured it out. I cannot run an overclock on my GPUs either without having increased instability.
