Could anyone advise me?  After my PC has been in sleep mode for a couple of hours and I go back to it, the display settings have changed.  EVERYTHING is large.  Is this the monitor's problem or the PC.  Also, once before, after sleep mode the monitor display had reduced in size and was surrounded by a thick black edging!!  Any ideas please?Don't use sleep mode. Seriously.Hi Broni,
Thanks for your reply.  Why not use sleep mode?  I used it all the TIME with my old monitor with no problems.  I would really like to know please.Windows power saving modes, like "sleep", are faulty FEATURES. They work for some, and they don't, for others. If you don't want to be in "others" group, don't use it.I use Sleep Mode very regularly, and only a few TIMES have I had problems. Many of the problems are small bugs that occur once Windows resumes.

If this is a recent development, try a SYSTEM Restore to a few days before the problem.Thanks for that Broni.  It seems to have only started up since I got my new monitor.

I didn't have trouble with my previous monitor, Carbon Dudeoxide like you also.
