Madshi can you please explain why the following does not work '1080p23, 2160p23' If I use that when the display is set to 2160, it cuts off a 1080p video and only shows half of the video on the display to the right and the left half is black. If I set the display to 1080 it shrinks the 2160p video to the top left corner (quarter) of the display and the rest of the display is black. Is there no way to fix this?

Anyway, does it really has any sense to have values 0 and 255 pass to 3D LUT then?
the video is supposed to be limited range that's all i can say.
removing BTB/WTW before it get's into the 3D LUT cost performance and WTW can be used and is not that rare in sources.

try to disable the windows scaling by setting DPI scaling to 100%.

i don't know why you should use 1080p and 2160p at the same time. resolution changing got quite messy with the newer windows version but not everyone is affected as always.

Yes, it should be limited range. But somehow this video is decoded to values of R that are out of scope for limited range. Although it doesn't look like full range video - the level of white color stops at 235.
There are lots of video that show some artifacts in saturated areas that become seen when using 3D LUT.

My question is - does it make sense to consider values 0 and 255 special that shouldn't be mapped by it? I know that they are used for timing information in video standard, but what is the use of having them in the output of 3D LUT?
Should there be any video timing information in madVR output?

could be anything from a mastering issue to encoding artifacts the list is long.

nothing wrong with decoding anything to full range even if the video is limited range. this is totally ok the issue is the 3D LUT handle nothing else.

the video timing part is even bigger. i'm not sure if they are present in this part there. for 1080p the send "image" has a size of about 2200x1125 with DMT timing.
a 3D LUT shouldn't be mapping it like this but that's really all i have to say. i brought this up to fhoech and i'm not going to force it on him. this is free software done by people in there free time there is a limited.
so that's it nothing more for me to do this topic is over for me.

i have not written a video renderer but i'm pretty sure there are no timing information that are of any important or most likely any timing information in the image what so ever.

madVR is not the reason for the issue.

The main issue I think is that for some reason 3D LUT file is created so that 0 maps strictly to 0 and 255 - to 255.
But there is no reason to do this, because these special values are not used by the application that is using the LUT file (I am talking about madVR).

Is anyone getting over saturated colors in full screen exclusive mode when using DX11? If I disable DX11 the colors are the same with or without FSE.

What's your graphics card? Should really flesh out your post.

AMD RX 480 with latest drivers (same with older driver though). I managed to fix it I think by setting the Windows color profile to wide gamut.

Yeah I already tried that thinking it might be DPi but it made no difference. The reason I wanted switching to 1080p for 1080p content was to lessen the load on the GPU when not needed.

What happens if you take "1080p32" off the list? I had an issue when both "1080p32 2160p23" are in the list. It was some time ago and I don't remember what the issue was. Anyway, it solved the issue with 1080p for me. I use an AMD RX 480.

That's a good guide, but it will be good to use examples of 23.976 hz and multiple refresh rates not 50 hz, also I can't use cru cause it doesn't detect my custom refresh rate, I'm on displayport.
Also using pixel clock calculator it doesn't show the exact timings for 71.928 hz...

I used that guide and I did not use CRU. AMD custom refresh rates works perfectly. I also used the guide for setting up my 59.940, 75 AND 71.928 rates... With current temperatures all 3 at "no drops/repeats expected"... So the guide is very useful even if you don't follow it exactly.

guys sorry for simplest question, others asked before but i cant find answer:
Is there a way to turn off the "Exclusive/Windowed" message at the top left when switching between windowed/fullscreen?
(I do want fullscreen to be in exclusive mode, just dont want to see the message everytime)

I don't find it a big deal because it stays there for a second and also informs you what's going on.

another question:
i cant use mpc-hc "save image" with madvr (dxva2 copy-back decoding + dxva2 scaling).
the output of save image is discolored mostly white picture with barely visible silhouettes, and the size of mpc-hc window, not the frame size.
will it be fixed? in the meantime, is there a workaround?

You're not the first to ask. I think madshi will add an option to prevent these in a future version. For now.. Close your eyes.
