Now I know this patch probably won't work for my old GPU but my question still stands as there *has to* be a way to unlock 1440p (or higher) for the HDMI port. My card can certainly do it (through DVI), so the limit is artificial.

The limit is not artificial. You're using dual-link DVI, while HDMI is single-link. Only HDMI 1.3 and later can handle 2560x1440 @ 60 Hz, but your video card is too old.

Three possible solutions:

1. HDMI ports can act as single-link DVI ports, so if whatever you're using on the DVI port doesn't need dual-link DVI, you can use an HDMI-DVI cable/adapter. Then you can use the 2560x1440 monitor on the DVI port.

2. The NVIDIA control panel will let you bypass the HDMI limitation with custom resolutions if your video card can handle it, so try adding 2560x1440 @ 60 Hz as a custom resolution. Keep in mind even if the video card can do it, the monitor might not support that resolution with a single-link connection.

3. If the monitor can handle lower refresh rates, you can try adding 2560x1440 @ 40 Hz as a custom resolution.
