My 2019 Predator PH315-52 Helios 300 doesn't seem to recognise HEVC codecs at all

I recently tried to stream my laptop to my TV using the host software Sunshine and client Moonlight, and after a wasted Saturday horsing around trying to get it setup I realised that I wasn't able to stream in H.265 (HEVC) at all; I was warned by moonlight that 'Your
Host PC doesn't support encoding HEVC'.

I did some further investigating and found that I cannot in fact play anything in HEVC format, this was even after purchasing Microsoft's HEVC Codecs from the store, and after reinstalling the third party HEVC Manufacturer Codecs which actually I can't seem to reinstall now. My GTX 1660Ti should definitely support HEVC, it's on this list: https://en.wikipedia.org/wiki/Nvidia_NVDEC

Any support or suggestions are welcome, I've exhausted my options and it seems like the only thing left for me to try is updating to Windows 11 which I really don't want to do.

    Are you using Acer OEM proprietary nVidia vga drivers from Acer downloads, not generic versions from nVidia downloads?

    Thanks for the support;

    I have downloaded all the VGA drivers from the link you provided, and performed clean installation of the NVIDIA VGA drivers. This is what I'm seeing:

    I'm still not having any luck running HEVC videos or trying to decode in HEVC unfortunately

    While the GPU is capable of HEVC, the PC's external video out ports may not be able to handle it. Does the TV and software handle DisplayPort signals?

    I'm not sure what you're asking; yes I can physically connect my monitor to the display port adapter but it hasn't made any difference as of yet to running and encoding HEVC.

    In the log files of the streaming service I'm using, I can see that it fails to use NVENC encoding.

    Sorry, I can only find support for internal output to its own display, not for its external outputs in this 5yo laptop.
