content: We recently sent a LeCroy Wavesurfer 64Xs out for calibration and was told the LCD was not working properly and that it would have to be repaired before it could be calibrated.We had them send the scope back expecting to find a cracked LCD or something along those lines. Turns out the scope seems to work completely fine except that the LCD displays everything upside down! The really strange part is that during boot the LeCroy opening screen and the command line screen are oriented correctly - it's not until it fires up windows that everything is rotated. I tried poking around to look for a setting that might explain this but it's very hard to use this way since the touch sensing is still configured for normal orientation.Is anybody aware of a setting that could explain this?

content: On LeCroy's Waverunner scopes you can use the intel integrated graphic settings to rotate the screen in 90° steps...

content: Blacknoise - that did the trick, thanks so much!Jay - I don't think the calibration shop was trying to stick it to us - they recommended us sending it to LeCroy for the repairs and warned us it could cost as much at $3000. I heard this third hand and said hold on a minute - send it back so we can take a look at what is really going on. Like I said earlier we were expecting a cracked LCD at which point I would have suggested looking for a suitable replacement and putting it in ourselves. When I say what was really going on I laughed and knew that it had to be a setting somewhere.The real question is how did the setting get changed? Assuming it happened here the only thing we can come up with is that the last time it was used we had it hooked up to a projector in a conference room so perhaps it could be a bug related to driving an external display. I really doubt that but I suppose stranger things have happened!

content: These guys are morons if they can't recognise a simple display rotation... it's a Windows PC, and... on Windows depending on version/driver you can rotate the screen very simply using ctrl-alt and the keyboard arrow keys. Someone might have hit that with a keyboard connected at some point either by mistake or on purpose, it's a common office prank. Who knows, maybe they did it themselves then tried to charge you for "fixing" it?

Check:http://www.alphr.com/features/391579/how-to-rotate-a-laptop-or-pc-screen-flip-your-display-sidewaysAs to the reason why it happened, I would be strongly suspicious there is a prankster in your ranks - obviously punishable by the gallows...
