Sharing a bad experience with Pierogi :

Yesterday I was visiting a friend. He is using LG M-2262D model TV/Monitor on his computer, to give some amusement I fired up Pierogi and shut down his monitor first, then up again. Nice I said, LG TV Keyset 1 works with this one . Then I tried to change the Input to switch the monitor to TV mode. I am not sure, I might have pressed another key more, but suddenly the TV/Mointor was in flashing mode

After that, no matter which keyset combination we tried, we were not able to take it out of flashing mode, even with the original remote and any instructions we tried from searches in internet. I had to leave with after 1 hour of trial & error, and still have no face to give him a call and ask if he solved it.

So the lesson: Don't play with other people's devices
