Thanks for the info, Derek, but the [RGB] option doesn't appear on the colour menu of either of my displays (or anywhere else that I can see and I've been through each menu from start to finish) or in the manual. I can only conclude that we must have different revisions of the device. Both my power supplies have always worked fine, for example :-) Thanks for your help, Mike ---------------------------------------- > From: sigma3@xxxxxxxxxxxxx > To: argyllcms@xxxxxxxxxxxxx > Subject: [argyllcms] Re: ColorMunki Create on CRT > Date: Thu, 31 Mar 2011 16:46:11 +0100 > > Mike, > > This is one of those "cussed thing" moments: The power supply in my 454 blew > up just before Christmas (for the second time in that monitor's life), and > I've been unable to ferret out the paper manual here. > > From (possibly faulty) memory, on the monitor's OSD "colour control" menu, > you'll have [RGB] and possibly [R] and [B] options ... > > [R] and [B] allow you to adjust the gains of the Red and Blue channels: > these may be hidden or inaccessible at the moment.
