No, scaling was probably already activated because it's not 1:1.

That would be graphics card properties or PowerStrip (if all else fails). But that makes sense only if your display can handle that!

HD = wider than 1024 or higher than 576

Sounds good to me.

I had the same low fps problem in MPC custom build with madVR, but when I went back to the Beliyaal-build setting madVR as a preferred external renderer, everything runs smoothly now. Getting 16/16 frame queues.

Strange. Could you please post the pin connection info? (right click -> filters -> madVR -> Pin Info). If possible for both the situation where madVR reports the funny resolution. And also for the situation where madVR runs fluidly. There must be a difference somewhere. I'd really like to know why madVR reports such a high resolution for you!
