I am interested in getting a 4k monitor but I’m wondering if it will hurt my computer’s performance. I have a 2019 MacBook Air and it runs great with a 1080p monitor as a second screen. If I were to upgrade to a 4k display would that increase the computing demand and possibly slow down the machine? I’m not too knowledgeable on computer science so I’m hoping someone here will be able to help. Thanks!
Sounds like you’re not gaming, so just simple 2d stuff won’t see much of a performance hit if any at all. You should be fine.
Gaming or anything 3d is where the real hit comes from when going to 4k.
