Video is window boxed on my new projector
RoderickGI:
I can see a very slight edge effect at the bottom right of the first image. It isn't a border though. It is an edge effect, and it looks like the image is very slightly rotated clockwise to produce it. That would be a projector issue.
Do yourself a favour and use the MC "Options > Video > Display Settings" in Custom mode to set the correct outputs to have MC and MadVR do the upscaling to 4K when required, with the correct framerate matching the source. Unless the projector is better at upscaling than MadVR. I used to let my TV do the upscaling but switched to using Custom Display Settings in MC. The difference is small, but I have more control for oddball video, and matching framerate produced an improvement.
PS: You might be able to hide (not fix, hide) the effect using "Crop Edges" in MC. Just start very small and work up until the edge effect doesn't show. That may produce undesirable side effects though, like an increased load on the PC.

Here are some photos that show the problem much more clearly.
I am using Red October Standard mode with a frame rate of 59Hz on the desktop.
One photo is with change rate turned ON. There is clearly a blank region on the screen before the black border.
The other photo is with change rate turned OFF. Here the image goes all the way up to the black border.

Ok hold on a second...
I'm going to chime in with something obvious, but no one else has mentioned it...
In both images that show the MadVR stats (which you say one has the boxed problem and the other doesn't) MadVR is outputting at the same resolution. The "draw" line in the OSD proves this. Refresh rate is different but resolution is the same.
So, unless you have been monkeying with the display settings, timings, or anamorphic settings in MadVR, I think the problem is not with MadVR.
You may have different timings or scaling settings set in your video driver configuration for the video modes associated with those "boxed" refreshed rates. Check there. You say 60Hz displays fine, but 59Hz is boxed. Check the settings in your video driver for overscan/zoom/etc for those refresh rates.
Secondly, it could be the projector doing this without involvement from anyone else. You might need to check there.
You can test these theories by closing MC completely, and just changing your Windows desktop resolution and refresh rate to match the refresh rates and resolutions you're seeing in MadVR. If the problem is with the video driver config or the projector, you will still see "boxing" even when MC is not running.
If there is never any boxing with MC closed, then show us screenshots of your MC Video Display Settings, and screenshots of your MadVR config for "display mode" under "devices". There will be little use in more talk without seeing those screenshots...
If the problem only manifests when using MadVR, then your MadVR display settings will need to be unborked.

I did the experiments without MC loaded and the window boxing still occurs.
Whenever the frame is lower the 50Hz, I see it with the desktop.
I tested my bluray player earlier and it definitely works fine at 24Hz with 4K discs.
The issue must be either the integrated video or its interaction with the projector.
So I have to stick to 59 or 60Hz unless I update the video adapter.

log your testings ... to see where problem occurs
somethubg like ...
1080p23 - boxing
1080p24
1080p25
1080p29
1080p30
1080p59 - no boxing
1080p60
similar for 2160p
since your desktop shows the problem ... its not MC related
like wer mentioned it can be either setting in GPU driver for zoom or zoom setting in your JVC that you accidently set
it can be called different than zoom ... overscan or underscan settings?
EDIT: if I have to guess ... I would bet it’s JVC settings as it’s much harder to screw with this in GPU drivers (especially such that zoom is different for different refresh rate)
My wild guess (I could be wrong) ... projector was not properly set up ... then you compensated that with zoom for your dvd content which somehow don’t apply to 23/24 content (video/film presets?)
