Right, so I'm looking into maybe getting a display port cable, but I don't have a monitor. I've just got a Samsung smart TV and I'm not interested in upgrading to a monitor at this time. I'm running my PC with a RTX 2080 with HDMI. I know DP cables have better performance than HDMI and I was thinking about switching to a DP->HDMI cable to see if I can get better performance, but I don't want to spend the money on a new cable if it's not going to have any benefit. Basically my question is: Is it worth it to get a DP to HDMI cable or just stick with HDMI?
P.S.
Probably a dumb question, but I've got NVLink with 2 GPUs, does SLI have any performance impact on DP output?
