Custom Resolution Utility (CRU)

In a perfect world, I'd like to simply change the resolution to 1500:1000 and disable high DPI mode. When I attempt to create a custom resolution of 1500:1000 in Intel HD Graphics Control Panel, it instead creates a resolution of 1504:1000 -- ostensibly because the horizontal resolution has to be a multiple of 8. It looks like the GPU scales this 1504:1000 resolution up to 3000:2000, causing blurring, ostensibly because of the non-integral scaling factor and the slight change in aspect ratio.

I am hoping that instead, I can create a 1496:1000 resolution that is scaled up by the GPU to exactly 2992:2000, so that essentially, one pixel rendered by Windows is rendered directly onto a 2x2 square of pixels on the display (without interpolation or anything fancy). This would waste 4 pixels on the left and right of the display, which is an acceptable compromise. I can set a custom resolution of 1496:1000 and the scaling mode to "maintain aspect ratio" in Intel HD Graphics Control Panel, which is close to what I want. However, it looks like the GPU is doing some kind of interpolation in the scaling process, which is causing artifacts like the blurring of sharp lines.

Is there any way to accomplish what I want with CRU, perhaps in combination with another tool or a registry tweak?

I don't think any GPU currently available will do integer scaling, so there's no way to disable the interpolation.
