At Sam's suggestion I tried all of this on another computer.
I had to repair my other observatory computer which then ran the ASI224 at all resolutions, although with about 60% dropped frames. I had to reinstall the USB3 card drivers before it was recognized as USB3 So I'm guessing the dropped frames are due to this setup. It's an older computer and uses a PCI to USB3 adapter, no PCI express slots.
The problem with resolutions is probably something to do with my video card drivers. After installing all the original software and upgrading amcap the screen resolutions produced on my monitor did not match the selected resolutions.
I will try these newest drivers but I suspect I will have resolve this video thing on the imaging computer to solve my problem. I may just upgrade the video card.
