Apply DSR to non-native resolution?

I have my gaming PC (gtx 1070 FE) connected to a 4k tv through an AV receiver that only supports 4k at 30hz. That means that while my pc detects 4k as my native resolution, it will only display it at 30fps. Due to that I've been running everything at 1080P because that is the highest resolution I can display at 60fps, at least until I'm able to acquire a new receiver. I've been told not to buy anything for myself until after Christmas, so I'm stuck with this setup until next year at least. :p

It occurred to me that I could use dynamic super resolution in the NVidia control panel to realize some extra IQ at 1080P, but the problem is that it only seems to want to apply DSR to the "native" resolution of 3840x2160, which of course will only display at 30fps. I was wondering if there was some way I could force the NVidia control panel to apply DSR to 1920x1080 instead so I can get 60fps, or lacking that, trick it into seeing 1920x1080 as my "native" resolution somehow.

Anyone know if this can be done?

Maybe try setting a custom resolution. Barring that Gefen HDMI Detective will change the native resolution in hardware via EDID.
