4096x2160p29 and not 4096x2160p30?The same? It can be done as it says.I guess you have to play with display mode settings.Something similar happened to me yesterday and I'm trying to reproduce it again. Last edited by Damien147; 13th February 2017 at 22:18. |

UPDATE:
issue fixed,just added 4096x2160p50 and it plays the particular 25fps source in 50hz. @tranfa try : 4096x2160p24, 4096x2160p25, 4096x2160p29, 4096x2160p30, 4096x2160p50 Last edited by Damien147; 14th February 2017 at 19:25. |

Have you tried different GPU driver versions? This is most likely a GPU driver bug. Quote:

Can you post a test frame (BMP or PNG) of the unscaled source, for which you prefer SXBR+SR over NGU (pixart)? Quote:

1) Please use display modes in the physical resolution of your TV, if possible, to avoid extra processing steps (which might harm image quality) in your TV. If your TV is really 4096x2160, then that's the right mode to use. But if your TV is actually 3840x2160, then please configure your HTPC to output 3840x2160 instead. 2) Make extra sure that all the refresh rates you enter into the madVR modes list are actually available, otherwise strange things may happen. 3) If things still react weird, you can upload a debug log and I'll see what's going on.

In all your tests, are you comparing just NGU pixart "very high"? Or have you also tested the lower speed variants? They don't seem to produce the same misinterpretations as "very high" sometimes does. |

To reproduce: just start any dvd playback, on the menu (if there's one) select the main movie or some extra. And then just seek during playback or jump to a random position : the player instantly becomes unresponsive (interestingly the bug doesn't happen when going from one chapter to another).

Just have to ask even if it's stupid.
My TV{(Samsung Ku6000 (or else ku6300)}is 60hz and says in the manual that it supports film mode only for 1080i in HDMI. In windows display adapter properties supported screen refresh rates are:24,25,29,30,50,59,60 hz. I played with display modes in Madvr and it seems that 24p,25p,30p,50p is activated and displayed in 4096x2160(Madvr and TV report it). If ''bypasses'' is the proper word do you guys think that what I am doing might cause problem/damage to the display? I mean I haven't found support for that officially. ---------- If everything's ok,24p(24hz) in 23.976 fps gives me 1 frame repeat every 42 seconds and no dropped frames in OSD.Does this look good?Is there room for improvement?23hz is not an option and no reclock because I'm 64bit.

There is one area where it has been a bit aggressive and I've marked it here. There's a soft smudge that NGU pix removes that NNEDI3 keeps and also the curve on the button gets pulled back to the left. I use NGU pix very high for comparison. High definitely looks better in the marked area, it's less aggressive so I prefer it for that reason but it's sharpness is quite low. Anyway you're right the video I linked you before is a much better test of low res animated content.. only NGU very high does okay with the lines (everything else loses to NNEDI3 32 neurons) but suffers from the line issues I've mentioned previously.

NGU problematic scenes Out of those images, the Slayers frame is by far the worst, but it's also very low quality, so it's to be expected. One thing I've noticed is that the smudged/wavy look is most apparent when doing NGU image quadrupling, it's not much of an issue otherwise, so this particular usecase I ran into (upscaling 480p > 2160p) is what makes it apparent. Some of those shots aren't all too bad, but if you switch back and forth between NNEDI3 and NGU quadrupling it's easily visible. It's also most apparent around areas with a lot of black outlines, but it does happen in colored areas too. I've used NGU vhigh across the board when looking for these scenes, with Jinc AR to upscale all the way to 2160p and deband set to Low. Let me know if you could use even more images, I don't have a lot of low-res sources, but I'll try to look for more scenes where the issues are visible if you need more stuff to test with. |

SXBR+SR = 4.92ms NGU Med = 5.41ms Nevermind it though, I probably shouldn't mention it in the first place as that's an issue with the AMD driver + RX 480 and not with NGU. Quote:
With real life content I often need to scale bad quality sources with compression artifacts. Guess what NGU does? It enhances (sharpens) the quality of the artifacts while leaving the actual data visually almost untouched compared to SXBR+SR. Sometimes it produces aliasing, sometimes it just looks too artificial to me, and sometimes it looks better than SXBR+SR. Therefore it's not a universal upscaler that I would use for everything. |

^ Fully agreed, NGU doesn't quite get through noisy/low-res sources as NNEDI3 & sxbr do.....I just hope sxbr won't be ditched and I might soon have to upgrade to a rx 480 as I'll prolly get a 4K TV so I'd rather have more options than less.
