I've had my pc for a while now and I think it's about time I get myself a second monitor however I'm wondering if whether I should 1. buy the same monitor 2. buy a cheaper one (the color difference will defiantly bother me and 3. upgrade my main monitor and use my old one as the second monitor ). The current one I have is the Samsung Odyssey G4 25 inch, 240Hz, 1080p. I mostly would use it for gaming and I'm willing to spend around $300-$400. Any help would be greatly appreciated!
