WOOOOOO thanks mate! Who would have thought! Getting super nice 110 hz without any frame skipping now smile.gif If this was reddit i'd give you gold, lol:thumb:

I bought the QNIX QHD2730R and im trying to review it for this site. I have it overclocked to 100mhz with ease so far. But I am trying to do the UFO test for frame skipping. I don't think I am doing it right because there isn't a lot of options on my phone for the camera like the iso etc to get a good picture. I did have it fullscreen which I found out was a no no, so when I get home ill fix that. I dimmed the monitor all the way down and even turned the lights off. Is there any other suggestions to make sure that I am doing it properly? When I play Assassins Creed Syndicate, it seems to be playing fine for me as well as a couple of other games.

Glad I could help

Update: Everything is more messed up than before now.

Last night I had super nice 110 hz on the frameskipping test on chrome, as I told you. This morning, after I restarted the PC, first thing I noticed was that the refresh rate i selected last night (110 hz) automatically switched back to 60 hz after the boot.

Ok, then I selected 110, checked on chrome Frameskipping test ( http://www.testufo.com/#test=frameskipping ) this one), and I got 20-60 fps with great lags and skipping. I also noted that Twitch.tv hmt5 videos showed great framedrops and fps lags. So I switched to firefox and other browsers, where initially the framerate was perfectly fine at 110 hz, also in league of legends (110 hz with vsync).

Now it is a mix of imperfect sync, but noticed 110 hz on the firefox test, but super ****awful twitch.tv performance on firefox (20 fps on 60 fps streams), and laggy 60 fps Frameskip results on chrome whilst having decent twitch.tv performance on chrome.

I am really puzzles how this one shutdown and boot of my pc from last night to now could make such a huge difference in these things, and how my PC seems to so much more trouble with the OC (everything works just fine in 60 hz standard mode) than with my old cards, like the 560ti or the 5850 HD.

I somehow feel like there is some kind of Vsync problem or CPU issue I cant get a hold of, as I have no clue where to check vsync settings of browsers and other non-game stuff. Could that be the problem=?

I have a msi r9 390 gpu and Windows 10. From what I have gathered I need 2 things to oc my qnix. The amd/ati pixel clock patcher and cru. Is this correct? And if it is correct ate the downloads on page 1 up to date? Thanks in apologize I am a noob. But appreciate all help.
post #366 of 458
That is correct. Once you make your profiles in CRU, you just need to use the display properties in windows and your refresh rates that you created will show up. You don't have to use the catalyst software and even if you do, it won't let you go very far in overclocking.

Thanks for all the info and help everyone. I was able to get to 110/112 Hz without artifacting (120 gives me horizontal green lines) using the tightened timings with no frame skipping on R290x. However I noticed that there faint vertical scan lines across the whole screen. This is not noticeable most of the time, but when there is some blue on the screen it is easier to see. I also sometimes notice it when I game. It's acceptable as it is barely noticeable, but it bugs me that it isn't perfect. Keeping it at 96Hz doesn't have this problem.

Any suggestions on how to resolve this? I have tried the following:

1. Tightened timings, even tighter than in OP
2. All variations of the polarity
3. Standard and reduced default timings.
4. DVI frequency change in CCC
5. Overclocking my R290x a bit (+150mHz)
6. Removed drivers and reset refresh rates (DDU/CRU) and updated to latest beta drivers.

Any suggestions? I am reluctant to try a new cable because this one seems to work fine and reading the owner thread looks like most people have success with the stock cable. Very few and far in between are there ones that have more success with another cable.

To be honest 96hz is a really good overclock. I believe that is equal to a 40% increase in performance if I am not mistaken. I rather have that and having to resolve any kind of lines, artifcats, etc. That is just me of course.

I bought a massively thick 24awg cable, got a new power brick that runs cooler and is rated for 72w/6A instead of 56w/5A http://www.amazon.com/gp/product/B00W5BNZR2, and I also set timings as low as possible and tried everything aside from debezeling and putting some heatsinks on the PCB. All just to get 120Hz without artifacts or image retention.

But in the end, anything around 110Hz and up has MASSIVE image retention. Forget the color and gamma correction, forget not syncing up to 23.976/24fps media, forget all of that. The Image retention is so bad that it's a deal breaker. Of course it's not permanent with these QNIX panels, but in less than 5 minutes of having a window open, it will burn it in to your screen so bad that you can literally read what it says 10 minutes after you close it. 96Hz vs 60Hz was MASSIVE, but due to the motion blur, the difference between 96Hz and 120Hz on these monitors is greatly diminished from what it could be. Motion blur and image retention limit practical use to somewhere below 110Hz, but that doesn't align with 24fps content. 108Hz is half way inbetween... but it still has some image retention that 96Hz just doesn't have that bad. I still occasionally game at 120Hz, and it's nice.... but not enough more to bother.
I feel like a pleb saying that too, I literally just killed my GPU in the pursuit of performance by sticking heatsinks where they don't belong. I'm going to debezel this QNIX and put some heatsinks on it too to see if it lessens the image retention. I've delidded everything and lapped my coolers, I go the extra mile just for a little more performance and do all kinds of crazy things. I'm not buying capacitors taht are of higher quality to replace the ones I killed on my GPU just to see if it will make a difference. So trust me when I say "this extra performance is not worth the price" in this case.

If the answer changes when I get around to adding a heatsink on the back of the monitor then I'll be sure to post about it.

So run at 96Hz, go to lagom.nl and calibrate your monitor by eyeball. bigeyedsmiley.png I've looked at every ICC profile for this monitor I could find but it doesn't fix the gamma. Once you fix that it feels like a whole new monitor. I need R1.21, G1.25, B1.20. (7 clicks down from max brightness). thumb.gif

Oh, and if you do decide to keep messing around with higher refresh rates I don't blame you at all, it's fun. Take this for the image retention. http://www.jscreenfix.com/screensaver.html thumb.gif

I've done some testing and I've find the CatLeap drivers to be best for my QX2710LED.

I can overclock this monitor and not get any color distortion with the CatLeap drivers.

On the other hand with the QNIX2710 drivers I get color distortion once I overclock the monitor.

Catleap Drivers:
Pros -
No darker color contrast once overclocked.
No need for third party apps to adjust colors (color sustainer)
Now Nvidia Control Panel can NOW control the brightness and contrast without it flickering back to the same brightness settings. I think this is a bug with Color Sustainer and NCP.
(This helps reduce PWM at full brightness on the monitor)

Cons-
This isn't a CatLeap monitor?
Doesn't help achieving a higher overclock

Now I can run 110/112 Hz on the normal colors without a ICC profile and no third party apps.
I can run full brightness to reduce the PWM and adjust the brightness / contrast through NCP (Nvidia Control Panel)

I hope this helps. I attached the CatLeap drivers and all credit is due to ToastyX for the driver.

Thanks catleap.zip 0k .zip file
