what's the difference between 15 and 31 khz monitors?

divergence · Post by **divergence** » Thu Dec 14, 2006 10:36 am

i mean doubled resolution is good and stuff, but how does it look? is picture only slightly better or it really makes difference?

That is about the dummest question ever.
Are you going to spam now?
Two cars one goes 100 mph and the other goes 200 mph
The 2nd car goes 100 mph faster, but how much faster does it go? is it only a little faster or alot faster
delete user, he will start spamming soon

i explain, for some hotheads here
cab with 31 khz monitor costs about one thousand bucks more, so is that resolution difference and picture quality justifies this huge money investment? on my pc i'm usually playing with 800x600 because i dont really see how is say 1280x1024 any better on my monitor. is my question still dumb for you?

yeah but you wouldnt play xbox360 on 800x600 would you?

same principle, some arcadegames run in hi-res, naomi, type-x and atomiswave to name a few.

a lo-res game wont look (as) good on a hi-res monitor and vice versa...

some? then i probably want to know how common hires games? what about cave shmups for example?
the easiest way would be of course to see for youself, but i wasnt able to find arcades around

Most shmups are for 15KHz monitors (low-res).
If you are wanting to play games from Cave, Psikyo, Raizing, Seibu Kaihatsu, Toaplan, or anything from the 1990s and older, you'll want to pursue the 15KHz option.

The Naomi and Type-X games use 31KHz monitors (high-res).
31KHz titles include Border Down, Chaos Field, Giga Wing Generations, Homura, Ikaruga, Psyvariar 2, Radilgy, Raiden III, Shikigami no Shiro II, Shikigami no Shiro III, Trigger Heart Exelica, Trizeal, Under Defeat, Zero Gunner 2, and maybe a few more I'm forgetting.

Short answer, the colors are more vibrant on hi rez monitors (playing high rez games) because it's not just double resolution, it's no black lines between the colors.

Isn't the Naomi also compatible with low-res monitors?

Also, is there any 'easy' way to get a high-res signal to component or something?

Can Atomiswave also do hi-res?

Interlaced for 15kHz. Not to be recappish, but it looks like relative garbage.

VGA -> Component transcoder would do the trick if you can get the wiring down for the JVS connector, I believe.

what about other way around? lowres games on hires monitor? sven666 mentioned they look not as good, why? 31khz monitor supposed also to support 15khz no?

btw thnx for infos, i guess i'll go for lowres cab and some cave shmup.

For divergence,

Yes, you can play 15 kHz low-res arcade games on a multi-sync monitor that's capable of play any of the three horizontal sync rates: 15.75kHz, 24kHz or 31kHz.

Or the other alternative is to pick up a Japanese Microcom produced XRGB upscan convertor like the XRGB-2 that has the exclusive built-in support option for the Taoplan & Seibu Kaihatsu arcade Jamma PCBs that output in the odd 54kHz sync rate like Batsugun, Raiden II, & the SP-1 mobo with Viper Phase 1/Raiden Fighters (SP-1 cartridges for use on the SP-1 motherboard setup) series Jamma PCBs (that would induce slow "screen scrolling" problem on a regular NTSC TV monitor -- assuming that one uses a Supergun setup with either RCA Composite Video, S-Video or Component Video outputs).

The cheapest way to play your low resolution arcade Jamma PCBs would be to pick up the Commodore Amiga monitor that accepts true low-res 15.75kHz horizontal sync rate frequency. The cool Amiga 1084S monitor has the required end-user monitor adjustment controls to be set to his or her liking -- absolutely essential for changing the monitor display screen size since each respective arcade Jamma PCB has unique display properties anyways (unless you enjoy playing games with cutoff display portions that really isn't curcial to gameplay). ^_~

Plan on paying about $20.00-$50.00 for a used Amiga monitor and hook up the five essential signal inputs: R, G, B, Sync, + Ground with a custom connection interface and you're good to go. ^_~

A multisync monitor that supports 15kHz and 31kHz (and sometimes higher) will have a finer dot pitch than a fixed-sync monitor designed to take a 15kHz signal, so the scanlines are much more visible on low-res games.

that post about amiga monitor made me think, maybe it's possible to build your own cabinet using some cheap parts. are there some resources on this topic?

Yes, I have a multisync monitor, and that explains why I wasn't that impressed after trying some games at their native (low) resolutions. I much prefer the look of them scaled up to 640x480 (31kHz). Yes, I know it's not authentic, but it's my personal preference

For divergence,

Yes, it's possible to build your own arcade cabinet using some cheap parts...by building a mini Mame arcade cabinet will get your neighbors "green with envy" alrighty... ^_~

You might want to head down to your local bookstore and see if they have the Extreme Tech book of "Project Arcade" -- Build Your Own Arcade Machine by John St.Clair and published by Wiley Publishing Inc. (ISBN 0-7645-5616-9) with a retail price of $29.99 USD or $42.99 CAN or 19.99 British Pounds for UK...awesome book and even includes a special CD-Rom disc loaded with a bunch of DIY (Do It Yourself) arcade cabinet projects. It was first published back in 2004.

Good luck find that "Project Arcade" book, it's an awesome companion book to see what it takes to build your own arcade cabinet..... ^_~
