@mclingo:
If you lost HDMI... I am guessing you deleted something you should not have in CRU. As for where this discussion should be, it's a madVR thing. mclingo could not get optimizations to work, and that is part of madVR. QB

try reading back Klaus mate, i've literally chucked everything but the kitchen sink at this including a different TV model, its this card as it works fine with my AMD 4650 1080p spare card, i'm just happy now with 3 hours using CRU, I can live with workarounds but I'll be dropping this card as soon as the next gen comes out in the hop it will be better, this cards has just had too many issues right accross the board.

@mclingo
It's not your card. As for your 3 hours... it can be better if you use madVR to optimize. CRU is really not the best or easiest way of tuning your custom resolution. Play video, optimize, reboot. The longer you play the video the better the results. With your 3 hours, play a full movie (don't pause or skip or do anything other than play) and after do the optimize, hit apply, and then reboot.

nvidia is just very buggy if you try to use there custom resolution tool which madVR tries to use. |

Yes, it is well known that the PSNR doesn't have a good correlation with the perceived quality, what I'm finding is that the so-called perceptual metrics yield very different results from each other, and neither do they seem to be too reliable when the difference between the images is very small. |

__________________________________________________________________________________________________________________________________ Regarding custom resolutions: If you are unsure what timings are used (e.g. whether madVR is successful with applying a different custom resolution or not) you can look up the currently used timings in the Radeon settings (settings - display - display specs). If madVR is unable to apply custom resolutions then normally it´s a driver issue. Then you always have CRU as a workaround. You can use madVR for calculation of the timings and use CRU for applying it by using EDID overrides and not the custom resolution driver route. All problems regarding custom resolutions can be worked around beside one: If you are unlucky you have a display device that is very restricted with custom timings and you get a black screen with most timings. Beside that it should be no problem to create the needed custom resolutions (the whole set would be 23.976 (or multiples), 24.000 (or multiples), 50.000, 59.940, 60.000) with an accuracy for frame drops/repeats every xx hours. |

Could someone make a Youtube video on setting CRU/ Nvidia /AMD and the Optimization part ?
I tried deleting all the other 4K settings including 23.976 settings from all the places mentioned in the guide, and it doesn't work, The readout now says 23.955 instead of 23.9755 (from before). This is on my AMD pc. The only 4K setting in there is the one I set 23.976 (23.977) through CRU I'm trying to understand the optimization workflow part ?

You can do it by trial and error. Simply set it a bit faster since when set to 23.977 is a little slow. Also, remember that getting very rare frame drops/repeats is the important part, not the exact reported refresh rate.

If this doesn´t work because of driver bugs, take the numbers from madVR amd make custom resolutions with CRU by using the given numbers. QBhd mentioned additional tweaking if it is needed to remove given timings. So that is all information that is needed to make working custom resolutions. No youtube video. Here at doom9 with madVR we are in the area of adult matter, not kindergarden showing a youtube video "put the yellow triangle block into the according place" |

that number is "irrelevant" you don't want it to be 24/1.001 you want it to be something that is not producing a repeated or dropped frame.
so the number you should care about is the clock deviation. http://madvr.com/crt/CustomResTutorial.html |

Actually mine is rock solid as well atm. No refresh rate probs like mclingo. Actually everything is working great for like 2 months now even with driver/windows updates ... I am not used to have a solid system for that long ... crosses fingers

So your audio clock deviation is shown with clock deviation. And your video clock deviation is 'encrypted' in display and the corresponding refresh rate Hz value. Display doesn´t need to be e.g. 24/1.001 = 23.97602 Hz. And clock deviation doesn´t need to be 0.00000 %. You´re only interested in "xx frame drops/repeats in xxx seconds/minutes/hours/days". Example: Your audio clock is running 0.01% too slowly. So the value of 'clock deviation' would be -0.01000 %. And your video clock is running 0.01 % too slowly as well (by pure coincidence). Then 'display' is saying 23.97363 Hz. As a consequence you will get "no frame drops/repeats expected". The absolute values of 'display' and 'clock deviation' are totally irrelevant in this regard. The relationship between them is the key. |

hi, is it not possible to tweak the back porch figure in AMD? could get even better timings if i could.

Of course.
Total = display + front porch + sync width + back porch. Because of this one value is redundant, AMD and others decided that to be the back porch for technical reasons. Leave the porches alone, raise/lower the total. That effectively lowers/raises the back porch. |
