Try unplugging your monitor cable, flip it over and plugging it back in.
You also see if a cross-over patch cable works.

This is actually upside down...it's just that as you read this, you are also inverted, and therefore it appears right side up.

[passel]

In response to Arnoutdv's question, and sadly to interject some seriousness, I was looking at a dump of boops boops original post before I made my first response to try to see if there was a character set that was being used that had upside down characters, but there wasn't.
The characters are just an assortment of characters from a number of different sets that happen to look like the characters we use, but inverted.
I didn't try to delve into depth, but for example, in some case the character is simply mapped to itself (s = s, o = o) and in other cases are a simple swap (u and n, p and d, b and q).

As for the capital T I didn't look at the hex bytes, but my first assumption was that it was one of the box drawing symbols from the old Code Page 437 set, i.e. the IBM Extended ASCII set used in DOS from the 80s. But it could also be the Korean vowel that sounds like o, or perhaps something else that I'm not aware of. Also the inverted 2 looks to me to be the Korean consonant that sounds like r or l (that's L) depending on context (I spend a little time in South Korea some number of years ago).
