I have a HP8591EM which has a composite video output on back panel. I've tried this with all sorts of video monitors (all LED). I know I can change modes on S/A and I did.
I cannot make the entire display show up on external CRT. the best I could do was have most it show up but very top and very bottom was cut off. Has anyone successfully done this? Can I get some assistance? If there is a make and model that works, I don't mind buying.
I know there was a discussion on here while back but I cannot find the thread. I have an issue with large amount of information presented all at once (such as search) so it doesn't help me much.

Does your external monitor follow theses specs ? Can it switch between Pal and Ntsc ?
50 Ω BNC,
NTSC, 15.75 kHz, 60 Hz or PAL, 15.625 kHz, 50 Hz
MONITOR OUTPUT
Drives an external monitor with a signal that has a 15.7 KHz horizontal synchronizing rate. It can also be switched to provide an NTSC format output
which is compatible with VHS video recorders or a PAL format which is compatible with PALSECAM video recorders

I have the exact same SA and have been through the same search for a compatible monitor without success.
Has anyone used a monitor that is proven to be compatible? Thanks.

Thanks. I have no idea what kind of spec my displays have on composite port. It's not listed anywhere other than it's NTSC. One commonality is they are all digital LCD displays. I think, nowadays, composite is an after thought. I'm looking for a studio quality CRT type display from the same era. Maybe that'll work better - and certainly has far more adjustment than consumer types.
I'll come back and report with exact model number if I'm successful.

Odd.... Horizontal scan rate on NTSC is 15.75KHz by definition of NTSC. That means any monitor can be usable.
Just to be clear... the image is stable. It's just that image does not fit the screen area. It's always too big in one way or another. If there is such thing as offset and gain for H and V, it should solve the problem.

Do you have vertical size and horizontal size adjustments ??
