Hi All!
I finally got hold of a new Lacie E22B4 CRT, but have some troubles..
When turning the monitor on from cold, the geometry of the display shifts and changes over the first 45 minutes or so. The most noticable thing is the fact that for the first half an hour, the bottom of the screen is clipped off the display (ie: Windows task bar is half missing in 1600x1200).
Despite the percentages and values in the OSD remaining the same, the effect is rather like something has altered the Vertical Linearity or Vertical Balance by around 20%. Over the half hour or so, the bottom of the screen slowly draws up into view. I also get a slight hooking in the top and bottom right corners, and pinching in the top left.
All of this sorts itself out in around 45mins after a cold on.
Lastly, when using the OSD (which is a bright white box) over an empty black Windows desktop), I get a thin red line on the right edge of the OSD, and a thin blue/green line on the left of it - which I don't seem to be able to irradicate with convergence adjustments.
Is any of this normal?? I've heard of CRT's needing up to an hour for their colour to stabilise, but never heard of such dramatic shifts in geometry etc..
Many thanks in advance,
S.
