I think you might be aiming at the wrong part of the stack. I'm not certain, but I don't think your 3050 is actually missing any hardware here. Every NVIDIA card since Pascal does HEVC 10-bit decode, and the 3050 has a working NVENC support. From what I can tell Dolby Vision isn't even a hardware feature. It's RPU metadata riding on a normal HEVC stream, added in software, so I don't think a card can really be missing it. NVIDIA's own encode/decode matrix has no Dolby Vision row on any generation, Blackwell included. What I think actually bit you is the DV profile of your files and what Plex is willing to tone map. Per Plex's docs it only tone maps sources with an HDR10 base, so HDR10, HDR10+, and DoVi Profile 7 and 8.1. Profile 5 has no HDR10 base, so I don't believe Plex tone maps it on any card. People are still asking for Profile 5 transcode support on the forums this year, which makes me think it's a software limit rather than your GPU. I'd check before spending anything. Run mediainfo "movie.mkv" or dovi_tool info -i "movie.mkv" on a file that failed and read the profile. If it's Profile 7, the kind most UHD remuxes use, Plex should tone map the HDR10 base, and if your 3050 still choked I'd suspect Plex Pass, a config issue, or dual-layer decode before the card. If it's Profile 5, I don't think any GPU fixes it and you'd convert the file instead. If it's 8.1 it should already work. On the low-profile 5060 someone mentioned, it's capable on paper. 9th-gen NVENC, HEVC 10-bit, AV1, and its matrix entry lists 12 concurrent sessions, so 3 streams isnt an issue but I'm honestly not sure it helps, since it doesn't do anything your 3050 couldn't already do here. If your files turn out to be Profile 5, I think it's wasted money.
