Review on Sceptre 27-inch DisplayPort Monitor E275W-QPT - 2560x1440P, Flicker-Free, Adaptive Sync, Built-In Speakers, Tilt Adjustment by Justin Franklin

This monitor was great for the price, but you do have to contend with a few annoying issues. The source selection is the largest, as far as I know there is no dedicated source selection button. Instead, you have to navigate through the menu to change the source. However, if you don't have an active source on the last port you used, you won't be able to open the menu at all, which can land you in a deadlock if you're not careful.
