MC and MadVR incorrect scaling resolution (ROHQ)

<< < (2/5) > >>

tij:
I didn't touch those … but checking it … resolution is 3840x2160 … Change the size of text, apps, and other items is 250%

Changing those around does seem to change how MadVR choose to render ... so thank you for pointing me in right direction

so when trying to output 1080p (for 3D stuff) ... scale of 250% makes madVR render 3840x2160 ... 100% makes 4800x2700 ... 300% makes 2743x1543 ... end result is Windows output 1080p

... now question ... can i turn this Windows scaling crap off (completely ... or just for MC)

You can disable scaling by setting it to 100% (at both resolutions) but that may mean the desktop is too small.
 
I've done a small amount of testing, and it seems that bringing up the properties for "Media Center 24.exe" and setting the DPI scaling override to "Application" in compatibility settings appears to report the correct desktop resolution in madVR's stats.
 
However, I have not done any testing of this to confirm if it actually means that video is being scaled correctly and displayed 1:1.

That did the trick … DPI scaling overrides to "Application" makes MadVR scale to resolution that display is switching too … THANX

only not so big issue … is when coming back to 2160p desktop after watching 3D in 1080p … MC UI looks LARGE … LARGE buttons … LARGE text … LARGE everything … trying to figure how to fix that

tij:
So … to summarize solution of avoiding Windows DPI screw up with MadVR scaling resolution choice (when its different from Desktop setting):

1. Go to location of MC program … right click on it and choose "Properties" … [Compatibility]->[Change high DPI settings] … tick "High DPI scaling overrides" then choose "Application"

2. after movie finish, MC returns to UI … and without DPI setting, the UI will scale incorrectly to correct this …  [tools]->[options]->[video]->[display settings]->[display setting automatic change mode] put on CUSTOM … and in [Default (used when restoring display settings)] I put "Desktop Settings" (other choices depend on your choices for watching movies)

This fix the problem … almost … my desktop is set 2160p60 … if last movie watch was played in 1080p23 … MC returns to 2160p60 after movie correctly … but if quit MC now, MC will set desktop to 2160p23


Bug? … fortunately I can live with this one :)


Thx again RD James for putting me on right path

GaryM:
May I comment... You guys are selling a product... your product wraps up MadVR as part of the offering. If there is a bug, even one caused by something in MadVR, it is >your< job to interface with the developer there to resolve it. We are >your< customers not his.

Thank you.

Although its likely that your system is just reporting weird things. I would recommend to let MC switch the resolution instead of letting madVR do it, that has proven to be more reliable in the past.
