GeForce GTX 1650 Ti GPU Acceleration

When using Wondershare UniConverter to convert a video to 3840x2160 (4K), GPU Acceleration does not activate. This is clearly observed in Task Manager. However, if I convert the same video to 1920x1080 (or below), GPU Acceleration is enabled. I tested this and it appears to be an issue with resolution and not video format, i.e., MP4, MKV, AVI, etc. Wondershare Technical Support tells me that this is a limitation with the GeForce GTX 1650 Ti. This is sort of a big deal in that with GPU Acceleration enabled, conversion times are very fast. Disabled, conversion defaults to the Intel UHD graphics hardware and conversion times are very long. I am not sure if this is a software issue or in fact it is a hardware limitation with the 1650. A couple more thoughts, purchasing the "Creator Edition" with the optional 4K Ultra HD+ (3840 x 2400) display, I find it odd that the Intel UHD default graphics can convert up to 3840x2160 (4K) but the Nvidia GeForce GTX 1650 Ti can’t according to Wondershare.
