Weird, I was offered a discounted U2413 almost immediately emailed to me - after I asked for it : /

I did not end up buying it. Hahah.

Btw, the price offered to me was RM1845. No citibank or etc.

It's doesn't seem like a monitor problem. You have a very unusual problem *scratches head*
Definitely try to swap monitors if you happen to have a spare one around
