Question about arcade monitor running at 30hz

[arcadepcnut]

Hello.
I know that it is bad for a arcade monitor to run at the vga output of 30hz (or is it 33hz). But how about if it is only for a few seconds. IE 10 seconds maximum.

I built the relay that powers everything on when I turn my computer on. I load the 15hz driver arcmon.sys as the first thing in my config.sys. However, the bios and bios summary and ram totals are all at the 30+ hz.

One solution is a timed relay. But A timed relay costs 90$!!

What are you doing to solve this problem? Im over the opinion that 10 seconds max at the higher frequency is not GOOD for the monitor but wont kill it either. Am I wrong?

I think we'd need more info...

how did you interface your PC to the arcade monitor?

Shouldn't this be in the monitor forum (not because I'm a forum nazi, but because that's where the arcade monitor gurus check more frequently/first)?

If you are using a J-pac you'd be in luck, cuz it doesn't allow anything higher than 15khz through to the monitor...

if you are using some other method (please describe) maybe that could be addressed in some manner as well...  there's got to be a solution as you aren't the first person to have to deal with the "bios" boot up screens on an arc monitor.

good luck (i'll poke around and see if I can find an answer to post though)

From the aos docs:

If the video output is selected to be
to an arcade monitor, ArcadeOS.EXE will beep 3
times when it has set the video mode to a
safe scanrate/resolution, you
can now turn on your arcade cabinet and play some games.

NOTE: If you set 'printhardware=1' in ArcadeOS.CFG,
ArcadeOS won't beep when it has set the correct resolution.
It will just send a byte to the printer port to operate extra hardware
to turn your cabinet or monitor on and off.
See the PC2JAMMA project for full details on building this hardware

So I guess that's one way...

Your right on the arcade os printer thing. I knew about it. I used to use arcadeos but not anymore. It was nice like two years ago.
I would build the printer port hardware if there was a dos driver to control the disabling and enabling of it. But as far as i know its a proprietary function of the arcadeos menu.



I am using an vga monitor cable that plugs into my videocard and then cut the end off of it and wired it straight to the arcade monitor.

I probably should not have even posted this message. I see no way how a few seconds at a higher frequency will hurt the monitor.

no.. it was good you did. someone else will have the same question (although I bet there will be some debate as to whether or not it is bad for your arc monitor or not)  

Maybe don't do the same exact circuit .. but seomthing similiar... when do PC's beep during boot (if at all)? maybe you could do something where it uses the tone from the pc speaker to throw a switch/relay...

just blueskying a bit... good luck (I would still like to hear if someone definitively says that 30khz briefly/often is damaging or not to an arc monitor)
