I'm using Windows 8 with only 1 laptop screen and I want to flip it horizontally, so it'd look like when you're standing in front of a mirror edit: example is the Ready word in attached pic. Win8 has some internal flipped display settings but all do it vertically. My onboard card Intel driver can't do it either. Quick searching on the net results in some apps like Mirroring360 or UltraMon, but it looks like the former is not free while the latter may require at least 2 displays, from what I read.
So, how can I do it? Are there other free apps that can do this?
