Thanks for the interest.
Yes, it appears that I indeed have 2 problems.
Using the same file on both computers, both of which confirm that the image sizes are 1024 x 683 and 4.71cm x 31.4cm, the NEC screen (18in diagonal size) shows a measured ratio of around 1.4 and the iMAC is 1.5. Both machines are set to a crop of 6 x 4; the
PC has Elements and the iMac CS4. However, prints from both machines are 1.5 in ratio, so clearly there is a problem with the settings on the NEC screen and I have someone coming to hopefully make the necessary adjustments.
Thus the sizes I quoted previously are correct and the full size image on the iMac is significantly smaller.
I had hoped to dispose of the old
PC so am reluctant to go down the path of using the screen in conjunction with the iMac
The screen size is 18inch (diagonally of course).
