Custom Resolution Utility (CRU)

I would like to run my potato gpu at 960x720@75Hz for games since I think the interpolation should be better than 800x600 or 1024x768 for a 1080p monitor (I could be wrong but I think it does look a bit less blurry, and it balances FPS and resolution).

1. I am able to use the intel graphics Custom Resolution dialog to add a "Basic" resolution of 960x720@60Hz to use that resolution. If I add a "Basic" resolution of 960x720@75Hz, 960x720@60Hz is possible, but 75Hz gives an unsupported timing message from the monitor.
2. The monitor out of the box supports 800x600@75Hz and 1024x768@75Hz, suggesting that 960x720@75Hz should be possible.
3. I am not able to install the Intel beta graphics driver because my GPU isn't in the supported list for the beta.

Now I tried using CRU, acknowledging that my GPU isn't supported. I have tried the various alternatives (detailed resolutions and standard resolutions). When I restart the driver, I don't see the resolution in the Display settings (Windows 10) dialog, and I don't have the option of using 960x720 in game. This may be because CRU doesn't claim to support my GPU and driver.

I have also tried putting the parameters for 960x720@75Hz from the CRU Detailed Resolutions dialog into the Intel graphics driver Add Resolution (Advanced). This makes the resolution show up among the possible options, but the monitor complains about unsupported timing when I try to use that resolution.

I've taken the parameters from CRU for 960x720@60Hz LCD reduced, and I am able to add this custom resolution using the intel driver. This resolution works. But attempts for 72Hz or 75Hz fail. At this point I am wondering what sort of parameters I ought to try with the Intel driver to get 75 Hz.

Any advice?

According to an Intel forum posting, as of the start March, the next upcoming intel graphics driver release for Haswell is 2-3 weeks away, and it might bring custom resolution support.

I would think it'd be possible for me to get 960x720@75Hz via the intel graphics panel, but I have no idea how to tweak the settings to get the monitor to work.
