Yeah only have a 42" TV and it looks very bad, the Picture Jumps up and Down 😀
Haha, I see. ^^ I've got the same issue anytime I use a CGA card.
Unlike MDA/Hercules, it doesn't use a proper 50Hz refresh rate, but is always de-tuned for some reason that's beyond me.. 😉
Anyway, using that V-Sync knob that you'll find on every video monitor really helps.

I also got a ATI Graphics Solution but the MM12 Monitor is incombatible with it. Can get the Picture on Hold.
I set it to Mono Screen but it does not work properly.
Hm. Sorry, I don't know what to recommend. Maybe the card is slightly off-frequency due to age, not sure.
Some Hercules had different crystals, so their frequency perhaps varried in the past also.
Or maybe it's the monitor that's a bit finicky here, not sure.

with the cheapo HGC Card everything is fine.
Hercules (aka Herkules or MGA - Monochrome Graphics Adapter) is awesome. It was very hi-res for its day and is on par with VGA in text-mode.
Speaking of VGA, some VGA cards even had an emulation mode of it. Because of this, I once thinkered with these little HGC compatible cards:
I thought myself "Why not the other way round, too ?" and experimented with a simple homebrew HGC-VGA adapter.
Unfortunately, it worked for me in text-mode only. Although it was supposed to not to (shoud work vice versa)..
See Hercules graphics on VGA monitors (mod)
By the way, if you're using a 286 CPU (maybe V20/30 or 80186, too ?) you can try out that C64 emulator.. It requires Hercules, too.
Re: "Childhood Embers" - 286 AT with Hercules graphics build
Edit: Not sure if you do know this, but CGA and Hercules can co-exist. Well, at least if only one screen page of Hercules is used (often the case).
That way, you can have a cool dual monitor setup! ^^ Simply enter MODE MONO for HGC and MODE CO80 or MODE CO40 for CGA (on DOS 5/6).
