[filmscanners] SONY GDM Monitors (was CRTs vs LCDs)

To the list --

I have a SONY GDM-F500R -- the previous version of the CRT under 
discussion. I originally had a SONY GDM-F500 (no "R") which failed. It 
periodically made a snapping noise and blanked the image. I returned it to 
SONY but their warranty repair did not fix the problem. I returned it 
again, and they gave me a GDM-F500R which suffered trapezoidal distortion 
that could not be adjusted out. I returned that unit which they replaced 
with a satisfactory GDM-F500R. This unit has provided good service for 
approximately six months.

These CRTs have a wonderfully sharp display, separate gain and bias 
adjustments for the three guns, more than enough brightness for PhotoCal 
calibration, great color stability, and I like the way they look too. I 
only wish I had more faith in SONY reliability and service.

One more thing concerning resolution: an earlier version of my Matrox 
driver offered what I thought the optimal resolution of 1152864 pixels at 
75 Hz. The latest versions of the Matrox driver provide an even more 
optimal resolution of 1280960 pixels at 85 Hz. This is much superior to 
the more common 12801024 (also provided) since it matches the actual 
aspect ratio of the monitor -- completely filling the display and not 
distorting the image. The Matrox driver lets you set resolutions for the 
GDM-F500R all the way up to 20481536, but I think this an entirely 
unusable option.

I hope this is useful information.
