IBM 2248 Monitor



Jan 1, 1970
Hi all,

IBM 2248 Monitor

Only displays a good centred picture at 75hz refresh rate. At 60 hz the
image is shifted to the upper left with 10mm overlap from the left hand
side.The horizontal and vertical alignment controls have no adjustment left
and are turned fully to the left.

When cold booting PC monitor comes on there is a squealing noise, a white
banded screen which instantly colapses to a bright vertical white line, then
screen goes blank. If the monitor is then turned off, then on after pc has
booted to windows the monitor works fine. There is no problem with the
monitor when rebooting, it is only after power off of the PC. PC is OK works
with other monitors.

Thanks in advance for any assistance suggestions,
