Hello,

I have a strange problem on Win7 - whenever I try to initiate my Spyder for calibration it tells me that one or more monitor is at less than 24 bit - so it doesn't work.

My setup is PC with AMD Radeon HD7800 card connected to 2 screens through HDMI matrix - this one. The screens are a HP x2301 monitor and a smallHD field camera. When I look at each individually they're at 36 bit. But Spyder insists not... as does my PC because it won't show me Aero theme (transparent bars that require 36 bit).

Has anyone experienced something similar and would anyone know of some utility or something that I can use to rectify or diagnose this. Tried the MS one, no joy, tried about a billion reboots. Updated all the latest drivers as well.

Thank you
 
Weirdly enough no. I just tried that hooking the monitor straight to the PC box but it still thinks there's a monitor at less than 24 bit although it only has a this connected, which reads 32 bit in catalyst control centre and all the usual windows 'devices' and 'drivers' screens. It's really weird and not entirely unannoying. Even tried making a new UA, same thing. grrrr.

I use the matrix because when I focus stack I pipe camera liveview output to the pc monitor and pipe the PC output to the smallHD (with a gradient background on CS3) - see http://extreme-macro.co.uk/field-monitor/


Ie this shot, the background is actually the smallHD with a CS3 gradient: Tiger Beetle by Johan J.Ingles-Le Nobel, on Flickr
 
Have you set up Remote Desktop or use any other remote access tools?
 
Months ago yes, not recently though. This just came out of nowhere... is there such a thing as a 'driver cache' or a way to get win7 to re-recognise a monitor afresh? I know prettymuch nothing about monitor profiles etc :(
 
Solved - dang you were close!!! It was some weird corruption with an AppleAir profile - after I sorted that by deleting every weird monitor profile using a cool little utility called "Custom Resolution Utility" it's now all fallen in place. Thanks!
