Back to the PAL.
I measured 54622D visible screen area from online picture and got exactly 5:4.
Is that correct?
Pictured knobs were round.
Vertical resolution was also sort of HD compared to 54600B but picture was JPG and not huge.
@mnem, did you measure your machine's H-sync, what was it's frequency?
From online pictures I'd guess that resolution is double and double compared to old model.
True double from that old schematics would be 24720Hz * 2, pretty much.
Back to the monitor.
Single color CRT doesn't need any rasters, if not for picture enhancement purposes.
Some older 546xx model online pictures have clearly straight edged pixels but some other ones are far from it.
So no raster.
Many kinds of CRT glow properties were also available.
So even if video monitor can be tuned to accept 546xx signal maybe its CRT internals are not suitable.
Resolution per se is not a problem.
Computer world had MDA and HGC but both are still under 20kHz horizontally.
MCGA was also available once, it is vertically like CGA/VGA.
The main issue with video monitor is interlace and its process.
There deflection goes from top to bottom twice and second round must be informed somehow.
If that then is controlled by a chip it may not like that half picture just continue continuing.
Vertical size is not usually a problem, usually it can be trimmed out of proportion.
With high resolution monitor its resolution can be an issue though.
There vertical pixel count is meant to be high and less of it can make a sparse picture.
There it can also go so that one line is missing but third is not, that is also what can be expected when resolution of signal and resolution of LCD are not buddies.

H -> V
Yeah, 625 line PAL is interlaced; I was thinking that when we were talking before.
That's another reason I decided to put a pin in this project; I'm waiting on the outcome of this eBay dispute. If I'm not keeping this turd, I think I'd much rather spend the time and brain power figuring out what went wrong with my fuckeroo UTG962E. And playing with my brand-new LeSiglent T3DSO2102.

Never any shortage of things a tinkerdwagon needs to do...
I'm a bit interested how this scope thing finally is.
For now my guess is that this 313 vertical has nothing to do with PAL.
Is there possibly a military grade high resolution video system with small screens?
Just wondering from where HP got their idea.
Somebody should count those H-sync pulses.
625 is raw PAL and it includes blanking time.
Somebody should also adjust their scope monitor so that returning beam is visible and count how many H-lines it needs.
That much is needed over that 313.
Old Hitachi schematics has very clear horizontal timing as 41.2us.
Is it the right device for sure?
Only one google hit for CDU-10BA241, title of Hitachi schematics.
https://www.eevblog.com/forum/testgear/hp-871xb-vna-crt-module-capacitor-identification-help/Much more for CDK-10BA242.
One of its CRT is 240ANB31N and earlier tube shuffle pays off.
As everybody remembers 31 is green, it continues so that 4 is white.
Tube in Hitachi schematics is 240ANB4(N).
Is this white CRT a rarity, is the whole input side of that schematics a rarity?
Maybe 546xx real H-sync is something else than 24270Hz.
