As much as I hate to get on the "it was better back in the days", what the hell is with PC displays and input selections?
I used to have a display that had input switch button and it would flip between its VGA and DVI ports. Later I had similar, but it also had a DP port and pressing the button would cycle through the options in order. This was the peak design.
For some reason after that I've only seen horrible abominations of this. Examples include the current Samsung 32" screen I have, which has plenty of input options but the quick menu only has "next input" option, which means either entering the quick menu, pressing next, entering it again and selecting next input once more to jump over something that's not connected. The direct selection is buried in the menus.
Another horrible case is a Lenovo display I have, which absolutely won't stick in the selection if it goes offline for a second. If a input source reboots, the display automatically jumps to an active one.
I'm shaking my fist at the clouds.
