Thanks for all your suggestions... Last nite I downloaded the proper AOC driver for my monitor, I was told it didn't need it... I tried anyway and it hasn't fixed it, just opened P4 added a Vickie 3 and started texturing, did a test render, started adjusting the pose and it went! Input not supported is generated by the monitor when the computer tries to do something it can't support, something in Poser (all versions) is triggering this! none of my other programmes do it!.. I'm at the stage where I'm gonna take the PC back... something inside doesn't like Poser!! I have been put in touch with a computer 'wizard', I'll show him your suggestions and if he can't suss it the shop who built the PC are gonna have to start changing things.. it seems the system I have just isn't compatible with Poser, or one of the components is faulty!!... and for me the thing that stays is Poser!...the rest can be changed!
