Hi Fred,

One thing to note is that these units are operating in different color spaces. The BVM CRT cannot do Rec 709, which is the default on the FSI units. On the 2450W you can switch to SMPTE C color space mode, which will make them closer. Also, you can play with the gamma setting as well b/c the programmed gamma of the FSI monitors is probably not exactly the same as the gamma inherent to your particular CRT displays. You can switch this instantly on the FSI units to see if you find a gamma setting that gets you closer to the CRT, if matching the CRT is really what your end users want.

We do deliver our 2450W set at 35fL peak white luminance. You can turn this down substantially if you like by adjusting the backlight setting. I mention this b/c often times CRTs (especially older ones) are nowhere near that bright and the difference in luminance can play a huge role in the perception of color.

So, you can certainly tweak the FSI LCDs to match the CRTs more closely if that is what you want to do. Whether you should do this or not I will leave to you to determine. We do calibrate against a PR-655 Spectroradiometer for all units that ship from us, but these are fundamentally different display technologies and some things like contrast ratio and spectral distribution qualities of the technologies (CRT vs LCE) are not really adjustable and will lend themselves to a slightly different look regardless of how well the devices are matched.
