So there's high DPI displays and non high DPI displays, Microsoft doesn't understand either and the experience of using both together is a complete disaster. I hooked up a 24" 1920x1080 monitor to my SP2. This is what Explorer and Firefox look like: Explorer (a NATIVE app) is blurry on the external screen. Incredibly blurry! Firefox was too, I turned off DPI scaling and now the UI is huge. You would think it would be easy to fix this, but it's not. There's a Windows 8.1 setting to change DPI, and a legacy way. Both are non-accessible via metro, and you have to RESTART the machine for settings to take effect. With these settings changed, everything looks decent on the external display, but poor on the Surface and all these settings have to later be changed back. Doing this every time I use an external display is pathetic. I paid $1500 for this machine. OS X just works perfectly with high DPI and non high DPI displays. Microsoft just doesn't understand how to do integration with external monitors properly whatsoever. edit: oh and not trying to bash Microsoft and go with the mentality that Apple literally just works and that Steve Jobs is literally Jesus. I've had my fair share of woes with OS X, but in regards to external display and high/low DPI support, Apple's crap just f***ing works.
