post #11381 of 25893
So i have been running with 96hz since overclocking and just decided to try and see if i could get 120hz and i can, but my pixel clock is 497, is that dangerously high???

Theres a picture of my backlight bleed, will attempt the tape fix if anyone thinks it'd help?

Not that bothered by it so far anyway...

no major backlight bleeding. but not really sure how to measure this. I do notice an overall "glow" when I display a black image on the screen. But Im assuming this is a fault of the panel technology rather than this particular monitor

I bought from dreamseller on ebay for $299

It was a risk and I was prepared to deal with a few dead pixels and some backlight bleeding.
But at 299 for a 1440p 120hrz monitor, this deal cant really be beat
So far extremely happy with the purchase!

Also should I keep it at 120hrz or should I move it back down to 96 to be safe?

Use a screen saver and you should be fine. If you get some image retention then set the screen to completely black for 5 minutes then white for 5 minutes and it will be gone. I run mine 120hz 24/7.

No but it is the stock clock for 120hz. The max normal data rate for these panels PCB is 450mhz. Running yours at 497mhzis an overclocked speed but it is definitely not going to break anything. If you see any side effects they wont be permanent and you can always try optimizing your clocks with my tutorial.

That is not that bad of bleed at all. The tape mod could help some but honestly if i had that panel i would leave it alone.

Cheers man, i just googled and found that. Are those stock timings of yours going to have any impact on image quality? It appears to look a little different on mine compared to the stock timings is all.

Yes the higher the pixel clock is technically above the 450mhz mark the more side effects you will have. Every panel is different and you may have no side effects at all. The gamma shift will be apparent but calibration can fix that. The effects you want to look for is mainly artifacts/lines or panel uniformity. Try putting a completely white background on and see if the brightness is uniform across the screen, if it is your good, if not then work your timings a bit.

Well if the only concern with such a high pixel clock is side effects then i will just stick with it because so far i'm not having any. I will have to recalibrate with my spyder elite, i will put the icc profile on here a bit later, it will be for max brightness 120hz, not sure who it was but someone asked me to do one for 120hz before so yeaha.


EDIT. Change of plans , going with 110hz as it keeps pixel clock under 450 so i won't be uploading it as i can't see a 110hz icc profile being useful for many people. If anyone wants it i will upload it.

I opened "color management" calibration for a couple of seconds, and without making any changes or even pressing "next", the colors on my screen suddenly became washed out, my screen became overly bright, and contrast disappeared. How do I reset to the default color settings? The display is fine on my other computer.

If you don't have an OSD, can everything be configured in software? Also, is overclocking really that useful?

thanks!

I'm still thinking over this too and I still can't decide what version to get since I'm gaming only occasionally. I have never owned a 120hz, but from what I've understand 120Hz should only be noticeable in fast games with a lot of movement. Apparently some people with sensitive eyes(sensitive to Hz or something..) could notice the difference even on the desktop and having a 120Hz monitor doesn't strain their eyes as much.

If there IS such a thing as sensitive eyes to monitor Hz I definitely consider myself one. So although I don't game much, I still lean more towards the single DVI-D port display just because of that. But then again whether the monitor is going to be overclock-able is still a question of luck even though it's a single DVI-D port version.

What do you guys think about non-gamers? Should we get single dvi-d version or multi-port version with OSD of this monitor?

DVI cable research....Another cable is always worth trying but don't buy any expensive brand name crap:
____________
This is more of an electrical argument than a research game. Any dual link DVI cable has a certain data rate that it is capable of and the size of the cable in terms of thickness is more about voltage over a distance. The thicker the cable the longer you can potentially send the data signal without data degradation. With overclocking you are pushing that data rate to its limits and cable quality does make a difference but it is not so much dependent of size, but is more on distance. The length of time the data is carried and the quality of the cable are the two main factors where size is a compensation for the length of time or distance the data is carried.

With this being said it is more important to get a very good quality short cable. If the thicker cables seem to have better results that would be worth considering in terms of how well the particular cables are made. The same could be said for a very short thin cable from a certain seller. This is why there are mixed reviews as no cable is equal(same as the monitor). The one thing that does show a very constant positive result is a shorter cable.

Over many of the tests i have done anything over 6ft seemed to have degraded results in stability per refresh regardless of the thickness. I originally bought 3 24AWG monoprice cables which had completely mixed results with one worse, one equal, and one better than the stock cable. After doing this i went up to work and tested about 30 DVI cables with the only constant positive factor being length.

After it was all said and done i found a random old DVI cable in a box at work that had no bells or whistles on ends, 24AWG and barely 3ft long that gave me the best results by a good margin(about 7hz over the best monoprice cable totaling 153hz). So go shorter than 6ft (as every cable i tried over 6ft barely hit 108hz) and get a few to try. Cables are not that expensive and if you have a few gamer friends there is likely several you can borrow and try to get the best overclock and don't worry too much about thickness.
____________

I see you are very dedicated for the research of these monitors. I thank you for your contribution (+ Rep) and I also thank you for posting some other settings that the majority can use. These work great and now I have absolutely no artifacts. My previous timings gave me an artifact (seen in dark situations) every couple of minutes.

120hz is not just for games. I can also easily see flickering @ 60 hz when seeing using my peripheral vision. Happens with my phone too. When I oced from 60 to 120hz, everything was smoother eg dragging windows, moving the mouse cursor. I can easily see the mouse "skipping" when I move my mouse cursor at 60hz. At 120hz its hardly noticeable. Like you're moving a physical mouse pointer across the screen.
