How to get Inspiron 5577 to use dgpu with 4k external display? - sh.itjust.works
I just bought a 4k tv for the first time, and I want to use my old Inspiron 5577 with a GTX 1050 as a media PC for it. But, the laptop defaults to the igpu, which only gives me a max of 24 (laggy) fps at 4k, and I can’t figure out any way to make the laptop use the dgpu instead. I can run individual programs with the dgpu, but not the screen itself. I’ve tried the Nvidia settings, and I’ve also tried “sudo prime-select nvidia”, which completes and then doesn’t do anything when I reboot. I’ve checked, and my bios doesn’t have an option to run the dgpu only. Am I SOL? I really don’t want to have to buy a new media PC when I literally have a graphics card in my laptop that can do exactly what I want already.
