Custom Resolution Utility (CRU)

Now, I can use an extension block using DisplayID 1.3 to add a valid 5120x1440 resolution, but then how can I edit the VRR range later as the recommended for Display Port is doing it at the "Detailed Resolutions" box, which I can't use since my resolution isn't detected there? It also detects a CTA-861 extension block where it correctly displays my VRR range for when the monitor is running @ 120 hz (48-120), but lowering the range there has no effect at all and I can still see the monitor duplicating frames when going lower than 48 FPS (and thus flickering).

5120x1440 is in the DisplayID extension block. The range limits is for all resolutions, not just the detailed resolutions box. That's just where the information is stored. If you see a FreeSync data block in the extension block, then editing that should work. If you have an NVIDIA GPU, make sure to replace the default extension block with a DisplayID 1.3 extension block, and add 5120x1440 @ 240 Hz. If you don't replace the default extension block, NVIDIA's driver will ignore any changes you made.
