I just read your post but hadn't built the adapter yet, I figured I have some time I'll do it now. built the adapter and then realized that the 9V in my TPG is dead and I don't have any spares... so I'll pick some up later today and report back.
What's the word brutha? JAMMA RGB compatible or can we write it off?I just read your post but hadn't built the adapter yet, I figured I have some time I'll do it now. built the adapter and then realized that the 9V in my TPG is dead and I don't have any spares... so I'll pick some up later today and report back.
Sorry man, I think the idea here is we find a monitor that can accept the signals we need rather than make some mods. Right now, seems the search continues.Hi, just got an 1970NX for use with mu Amiga 1200 and got mixed results.
It does 15khz but only 240p, jet i would need 288p for nice over-scan.
Was wondering if we could build a suitable panel with an LCD controller board with nice RGB inputs?
I was searching Ali express but am not that knowledgeable, perhaps something like

I built the harness but something's wrong with tester, It wouldn't produce an image on my LCD so I tried it on a few good working arcade CRTs and it didn't work there either. Replaced the battery and still nothing.What's the word brutha? JAMMA RGB compatible or can we write it off?
I was working with what monitors my buddy has at his office to setup his MAME PC's. He had 3 crusty LCD's laying around. They all ended up displaying 15khz signals well enough to get the job done for installing CRT Emu. Heck, even my Dell UP3011 displayed CRT Emu's 15khz signal which was shocking.I take it this list hasn't been updated in a while? I'm looking for an 19 inch monitor or TV that supports 15Khz VGA but the ones on the list don't seem to be made anymore.
You mean Acer?Finally found a monitor for my bench that perfectly syncs 15khz and upwards direct via RGB through the VGA connector. No line sync adaptor, no convertor... Direct RGBS from the JAMMA edge.
Model: Address G237HL
23" IPS monitor
This is perfect for me to work on boards as I needed a Tri Sync and didn't feel like planting a huge 29" tube on my bench.
Thanks to my mate Skylersz for running tests up at his end.
Will add some pics soon.
Can you try a CRT Emu hacked PC for MAME if you have such a box handy?Sorry edited the post (autocorrect).
I've tried it with a bunch of boards. Anything specific in mind and if I have it I'll test it.
Tested with Super Off Road (syncs at 17khz), Big Buck Hunter COTW (syncs at 26khz) and every other 15khz game works.
usually C-Sync would be routed to H-Sync if it's supported.@Holy-snes, what pin do you have C-Sync connected to on the VGA connector? Pin 13 or 14?
The MK games have one of the worst WTF sync setups. honestly Midway games in general are like thatTry mortal kombat, MK2
Thanks for trying! I’m not surprised, there are a few boards that are just awful for sync. Sometimes even my small pvm complains! Most LCDs don’t have a chance, but you could couple them with something that buffers the frame rate to 60hz for universal compatibility. Wouldn’t be great for gameplay but fine for a test bench.Ok it seems this monitor has met it's match.
I don't have any of those boards currently, but I have a Raiden 2 which I just tested and 'input not supported'. I think what I'll do is have a VGA convertor set up and use that for boards that aren't supported for this monitor. That's if they sync with those crappy convertors.
Is there a list of these 'sub 59hz' games? And is it only sub 59hz?
I don't think you've understood the point of this thread. this is about finding monitors for testing purposes. I could give two shits what the image quality is like. it's about finding a cheap, compact and light weight 15khz monitors for use on a test bench or to throw in with your tools when helping a friend diag their machines.Anyone looking for a genuinely good image for old games should obviously avoid flat screens entirely. LCDs have a fixed pixel pitch so they can't switch resolutions like a CRT. Nothing can change that. The best any LCD can do is take all those obscure arcade resolutions and scale them to fit their native pixel pitch. Scaling of any sort is always a compromise.
The question is about which flat screens can display old games, If the question is "which will produce a good image from old CGA or EGA PCBs, the answer is "none of them, without external help".
If a flatscreen is the only option, my advice would be to buy an LG Oled and invest in a decent external scaler. I use CRT monitors for everything CGA, EGA and VGA but I have a 77" LG Oled in my living room. The LG Oled produces the best image combined with acceptable lag in game mode out of all the flatscreen options. It will display a 15khz 480i image via it's composite video port too (although it looks terrible).
Like CRT, Oled lights pixel phosphors individually so the tech does a decent job of replicating the crt glow and contrast. It's still inferior to CRT for motion blur though and you can't use interpolation to help that in game mode.
