Should I buy a Monitor?
So I have a Sonnet breakaway 550W with a 1660 super graphics card, and I use it on my HP Spectre x360 15 model. It works fine, but when I try to play cyberpunk 2077, it never goes above 25 fps even on complete low settings. I am pretty sure I have a strong enough graphics card. So I am wondering, should I connect the egpu to a monitor display instead of just using my laptop screen? Would that make a difference? I just dont wanna spend some more money if i can avoid it since I already dropped 500$ to make this egpu already. Please help! Im new to this whole eGPU thing
You will get an improvement connecting directly to an external monitor. The connection between computer and eGPU can only handle so much data. When connected to a laptop it's sending data to the eGPU, and then returning the result over the same connection. Hooking it directly to a display means more bandwidth is available and that will feed your graphics card faster. The improvement varies between games however.
Suggestion: Connect your eGPU to an external display you have handy (a TV, borrowed display from a friend, etc) and try playing it at the same settings you'd play on your laptop. If the resultant gain warrants the purchase of a display in your mind then... yea get an external display.
I'd wager that an external display would benefit you regardless since it brings a lot of benefits (larger screen, better posture ergonomically for you, etc).
