Monitor spec: QHD 2560 x 1440 at 60 Hz That is within the HDMI specification so no point in using a bunch of adaptors.
I have a sparkling new G15 5520 (RTX 3050 GPU) plugged into a Dell U2722 monitor.  I purchased a Dell USB C to DP/HDMI adapter in order to connect the laptop and the monitor via DP.  However, I can also choose to connect to the monitor using HDMI without using any adapter.  In either case, I have speakers connected to the monitor that I am using as the audio output. I cannot note any difference in the video or audio output whether I am using DP or HDMI.  It seems all the same to me. My question: is there any advantage to connect to the monitor using DP?  Do I get (at least theoretically) better video or audio performance?  If not, then there are advantages to using HDMI unrelated to AV quality, most importantly, one less adapter. Thanks for your input if you have any insight to share.
