1 GPU 1 Monitor, and Elgato

[Sin(x)=0.933...]

Hello there, I have a GTX 1070, a view sonic monitor (able to operate at 75hz) and an Elgato HD60, Sometimes when my PC turns on (when they are all connected (so gpu->elgato->monitor)) my monitor would act wired random lines would show up  (a lot like static,) I would unplug and re-plug my HDMI (elgato, and power) then it would return to normal, one day (today) I opened it up and it had this wired effect like your looking from top of a fire (or hot surface) and you see things a little off (kind of like moving) so I decided to find a fix and decided to plug my elgato into its own HDMI port and the Display into its own HDMI port. I found a solution, to open up NVIDIA Control Panel and under multiple displays, clone my monitor, then go under adjust desktop size and position to set them to different refresh rates (both at 1080p for me) the guide, said to set No scaling and GPU, and for both "monitors" and they both worked, so here is my first question whats the difference if I kept Aspect Ratio vs No scaling? Second, Would this put more load on my GPU? Finally, is there a better solution or is there a problem with any of my equipment? (it's worth noting that I had a noticeable amount of desync (like I would need a G-Sync monitor to solve) towards the bottom of my screen, when I had them all plunged in together) <--will this problem be solved now? is it also normal for chrome to take a second to adjust (from full screen to 1/2 screen for example) or is that just me?
