You can get two in one out kvms for pretty cheap these days. I got mine which is a three in, one out KVM with support for three displays all at 4k120hz along with 4 usb ports for about 20 bucks (although that was at one of those Amazon returns stores. New it would have been around 120 bucks, but totally worth it. I have my work mac and my personal laptop on the left/right of a 4k144hz monitor (although as others have noticed usually you're limited to 120hz through a KVM, but that's fine for me), along with my home server connected for the odd time I need a direct connection to it. Would recommend.
