Sorry for trying to help. Should have just done it like a smart ass like you rolleyes.gif

Yes i am a smart ass because i constantly try to tell people to go fishing rather than ask for a fish so they can be smart asses themselves. I simply try and push people not only in the right direction but also a bit towards helping themselves in the process. Also saying sorry for helping is just trying to setup a victimized outlook thus demonizing me, not appreciated, and doesn't help anyone. I just explained my comment that was all. Honestly this should have stopped with my original comment. Please PM me any more comments like this since it does not contribute to the thread.

On a better note i have gone through the thread and grabbed each of my more informative posts. So if anyone wants the downsampling instructions, timings optimizations, pros/cons, BLB fix, review posts PM me and i will forward them to you. I am not going to repost them though they are all in this thread like 3-4 times already.

I'm pretty sure for some reason whenever I overclock my video card it contributes to the problem.

Example: run video card @ 1200mhz @ 60hz refresh -- no problems
run video card @ 1000mhz(stock) @ 110hz -- pretty sure no problems
run video card @ 1200mhz @ 110hz -- all hell breaks loose.

So if my video card was oc was unstable, why does it work fine @ 60hz as far as I know. Shouldn't the video card oc have nothing to do with the refresh of the monitor? All it does is sends out a signal to be displayed by the monitor. Shouldn't I have issues @ 60hz? Since the video card core clock has nothing to do with the refresh rate of the monitor.

I haven't even confirmed fully yet the stock video card settings is stable w/ 110. I am working on that for the next few days and if nothing happens i'll say it is.

but THEORETICALLY my monitor is still capable of 110hz even with an oc'ed video card. My 7950's ran 1150/1500 the whole time I had them @ 110hz with no issues.

So I guess the test will be if I run @ 1000mhz (stock) on the video card and 110hz (known to be stable on this monitor with other amd cards.) and I have no issues, will that determine that something was wrong with the video card oc settings? I really don't want to have a video card I can't oc at all since if I can't OC I'm wasting my time trying to get over 90fps in most games anyway.

So far my options seem to be: Run 1200mhz @ 60fps
or run 1000mhz @ 110fps.

Now I know what you are thinking. It's got to be an unstable video card OC? Well I've tried lowering the OC also to 1100mhz and I remember getting the same garbled screens. (any 290/x should be able to do 1100 MHz stable imo) or it's a piece of junk

No you could very well be onto what your problem or at least part of it. GPU and VRAM overclocks can have a BIG effect on refresh rate overclocking. There is a bit of talk about it earlier but it is all but lost. Chances are that some of the lower overclocks may not be fully stable either and it is not apparent on the desktop. Depending on driver versions there has been members that have found ANY overclocking of VRAM undermining there monitor overclock.

I have found that my card looses monitor stability if i overclock over 1250mhz at 120hz(and this is big since i can overclock to 153hz normally). I would try bone stock GPU and VRAM clocks first and see how that goes. Also see if your timings not being standard directly correlates to your GPU clocks and stability(saw this happen at 120hz.net).

Lastly i haven't found any actual connection between the effects of GPU overclocking and monitor overclocking. I think over in the random catleap threads someone made a very good point on how VRAM overclock can effect the timings due to the processing of pixels > the blanking period and optical blacks DE-stabilizing at higher speeds but i can't find it right now. but if VRAM and GPU speed are related one could just push the other to instability(like the wrench in the machine complex)

LOL yeah that would suck if the GPU clock is locked at overclocked speeds, but another thing you could try and is slightly underclocking the VRAM to see if that makes a difference and allows you to up the GPU clock. This can be effective, i underclocked my 780ti's memory and got another 60mhz out of the core clock(which was still a nice bump in FPS with no monitor OC effects, kinda like a trade).

these are the settings I have used on this monitor for 4-6 months on the 7950's I had with no issues.




You seem to say video card oc'ing has an effect and then doesn't have an effect? Sorry I'm just a bit confused.

if you were me would you keep trying my 110hz that I know my monitor has been able to do previously (on dif cards) @ stock gpu settings to rule out monitor degrading somehow or what would you do ?

Really sucks if I have to choose between a monitor OC and a Video card oc. Some people here say they have 290/x's and these monitors oc'ed I wonder if they have the video card oc'ed also? Should I consider an RMA on this card?

After using CRU and OC'n my X-star to 120hz, I can't watch any videos. They are blank screen.
I have tried going back to 60hz using 2nd LCD which is not OC'd and even moving 2nd LCD to Intel inboard GPU.
Anyone seen this?
Thanks

Hmm I really don't want to have to underclock my video card in anyway. I'll be doing an RMA if it comes to that.

I am saying it does have an effect and they are a bit linked. I have an overclock on my GPU making it 1241Mhz, but if i turn off my monitor overclock of 120hz to 60hz i can get my GPU to 1313Mhz. That is almost a 9% difference in overclock due to the monitor keeping stability. Now this is not always happening since i have found people who did not see a difference(at least at 120hz or 96hz and they may not have tested it as much as i did to find those limits).

If i were you i would do what i always do, test the whole setup with all the variables over and over and OVER again till i find the absolute best sweet spot and the limits in either direction. You might find the best place to be is a moderate/high GPU overclock with using 96hz(with custom or stock timings). You might also find that VRAM or a certain timings setting with the monitor was acting as an anchor(like finding that a 100mhz VRAM underclock resolves everything or something). IDK about you but i enjoy troubleshooting stuff like this almost more than actually playing games/using the hardware so for me your in for a neat ride.

I would not consider an RMA until you really narrow down all the aspects of what is going on. There is always the possibility you will find a work around. You may also fin a wall with the card and if you are not satisfied and you see much better performance from other users(including the monitor overclock, got to keep variables as same as possible) you may want to try again with an RMA if it is not costly.

Lastly, those timings look fine but you could try setting the sync width to 1 for lines and the front porch to 1 for lines. It gives you a slightly longer blanking period but i couldn't see any extra blurring at least at 120hz.

what video player are you using?
nvidia or AMD GPU?
have you checked your scaling options?
lastly have you checked video hardware acceleration?

I definitely understand that but as a matter or troubleshooting it may be worth it especially if it is only like 50mhz and fixes your whole issue.

I enjoy it to a degree but I am now past that point and would just like to enjoy my 300$ monitor and my 500$ video card @ 96-110hz with some decent video oc to help push those frames.

Should I be using alternate dvi operation mode in amd drivers or not? I saw somewhere ToastyX said to leave it on.

I can relate to that. Sometimes the work has to stop even if ti is fun.

Concerning the DVI mode, This is a quote from ToastyX from 120hz.net and is the best description i have found(props to ToastyX)

""""""""""""""""""
These options aren't really documented, so I can only guess based on what I know.

"Reduce DVI frequency on high-resolution displays" probably has no effect on most monitors. Back when video cards, monitors, and cables could barely handle the full single-link DVI bandwidth, some people were having signal quality problems with 1600x1200 monitors like the Dell 2001FP. 1600x1200 @ 60 Hz without reduced blanking is close to the single-link DVI limit of 165 MHz, so that option would use the CVT reduced blanking standard to reduce the pixel clock to around 130 MHz to get a more stable signal, similar to how we reduce the timing parameters to get a better overclock. Nowadays, most LCD monitors use CVT reduced blanking by default (or EIA/CEA-861 for 1080p), so that option wouldn't have any effect. It should be left off so it doesn't mess with the timing parameters.

"Alternate DVI operational mode" is coherent mode, meaning the clock and data are synchronized. Originally, DVI was non-coherent because the clock multiplier caused a delay in the clock signal that needed to be compensated for at the receiving end. This caused problems when using longer cables because the length affected the delay. Nowadays, everything is designed to use coherent signals for better stability, so this option should be left on. It shouldn't be turned off unless you're using an older non-coherent display.
""""""""""""""""""""

With that said i would leave it on if i used AMD cards.
