Rich, that's not a Sony BVM, although I'm sure it's a sweet pro monitor. Most monitors don't track hours but a few high-end JVCs do. If yours does, you will need to get into the service menu and poke around (not the regular menu).
So there's a problem with the Ultra HDMI N64 that I'm hoping has been or will be fixed with a new firmware update. I enabled the mod's deblur setting, working nicely as expected. Got the APS patch files into the Everdrive for disabling AA in certain games and it did exactly what the MLiG guys showed. The two combined give a nice sharp image... but it NEEDS the scanline filter so it isn't a line doubled, pixelated mess. It really completes the look.
But the scaling is not 1:1 and looks blurry, which sort of undermines the purpose of all this. There IS a sharp pixels/integer scaling option but it disables scanlines and most of the Ultra HDMI's settings (no idea why, it makes no sense to me). Basically, you can't have all the necessary settings turned on at once that would give the optimal picture quality when that's the point of this mod!
Using the dual output of the modded N64, I did a side by side comparison between the N64 S-Video output going to the low-end JVC and the HDMI outputting to high-end JVC HD monitor. The S-video setup still ends up looking clearer and sharper than the fancier setup, especially with the disabled AA enhancement coming through very nicely on the JVC. It may not be completely evident from the pics below but the one above is noticeably better in person.

I tried to test with more games but my rom set isn't No Intro and, even with renaming to match filenames, most of the patch files did not work with the roms. Working on getting the No Intro set.
Does a direct capture device grab a completely raw image without the characteristic of the display? If so, then I am better off snapping pics of the screen. Direct grabs of the dual output setup above would make it seem like the HDMI output is objectively superior.
