AWave + 60kHz TV = wavy picture?

ray_7 · Feb 1, 2006

Hello all it's me again.

I have this issue about the AW that has been bothering me for some time so now I'll post it here and see if any other guys have the same issue.

I can confirm that this is not caused by the supergun or a defective AW mobo. I have 2 brand new mobo, and both have this issue. You see, when I plugged it in to the TV through the supergun, I noticed that the screen is somehow "wavy". Its kinda like PSP's menu screen if you know what I'm talking about.

At first I thought it's the fault of the supergun but I'm wrong. I tried it with my Neo MVS and the picture is crystal clear. Oh, I'm connecting it with Component Video btw. So D-Lite and me has been discussing these and maybe it's the compatibility issue of the AW and the TV itself, a normal 60kHz TV I mean...

So any other guys here using supergun and connect it to normal TV have this problem as well?

Through a supergun or consolized, via direct RGB scart, in my 60Hz compatible sony TV, the AW has crystal clear picture.

I did some testing last night too and found that the AW does have a slight "wave" to it throughout play. This is using the NeoBitz and a supergun. But also is through all video signals with AW, but not at all with NeoGeo.

I'll try again with a JROK and see if the wave persists.

D, checked it already?

Amano Jacu · Feb 3, 2006

Well, now that you mention it, when I used the AW with my "Supergun II", that features composite and s-video through an ancoder, as well as RGB, the picture was a bit "wavy", even using RGB. However, using a direct connection through a RGB-only supergun or consolized, the picture is 100% crystal clear to me.

I should be able to try the JROK tonight Ray. Will post here on that.

i hope that works perfectly with the awave.

if it does, is it possible to change my encoder then? ;P

ot: which one is better, neobitz or jrok?

Honestly I bet they have the same effect. Amano, was your supergun with a JROK?

omg D, you won't believe this.

i see these waves too on the mvs...

seriously...

not as bad as the awave but its definitely there.. happen just now..

You didn't see them before? Are they new?

well.. before this i usually notice those waves when playing kof xi..

when i play my neo i've never noticed such thing, its all good and pretty.

just now when i play the neo again, everytime the screen goes black i would notice this waves again, but much less compared to awave...

Describe the waves a bit more for me. Are they strictly vertical or crawling diagonally? Are they only during black screens or visible in black parts of multicolor screenshots?

ray_7 · Feb 4, 2006

okay i'll try my best.

the waves are mostly diagonals, just like those you see in the awave, but.. the distance between the waves are quite far apart. hmm lets put it this way, say you see 30 total diagonal waves in the awave at one time, in the neo i see like 6 or 7.

they are mostly visible during black screens (character select screen changes to battle for example). and during match (when the screen is full of colour) they aren't really noticeable, but if you look at it carefully, its still there, makes the screen kinda flicker...

It isn't called an Atomis-WAVE for nothing! LOL

Seriously, I have seen the wavy lines on RGB tvs before, (a long time ago with the super famicom) Is your TV old??? Older TVs in my experience can be problematic and will display wavy lines with certain inputs..

ray_7 · Feb 4, 2006

well all my tv's are new.

toshiba crt 27a45, sony bravia 32" lcd, samsung 20" super slim lcd... i bought them all this past month, and all displayed the waves...

Amano, was your supergun with a JROK?

No, it has custom board featuring a Sony chip, I think it's the same as the featured in the AES, CX something I think, can't remember the code.

Then it is basically the JROK. The chip in the JROK is a Sony CXA2075. The AES uses a CXA1145, which is very very similar.

This indicates that the wavyness is an AWave thing in general since it occurs across different chip types.

hmm so the best solution is?

i think i want a cab now...

Haha, a cab is always a great thing to have if you have the space and whatnot since it's RGB. What I'm curious is if this wave thing is always present and I think it may be since Amano also sees it and I believe that supergun was made by supergoose. Since arcade boards were never meant to be played anywhere other than an RGB monitor. And I think once you look for the waves you'll find them. Does that make sense :chimp: ?

I will continue to look into it and I hope other people give their observations too here!

norton9478 · Feb 4, 2006

I've even had some problems with "Wavyness" on my old cab....

But I've never had a problem with my VGA monitor.

yeah i know what you're talking about. and since i'm kinda picky, thats why i always see those waves...

dean, do you know anyone local that sells the astrocity?

Sorry, I didn't explain myself well. The supergun I'm talking about is this one, it was made in Hong Kong and features that CX chip, although I use the RGB output:

With this supergun I noticed somehow those "waves".

However, when using my AW with the VHSgun made by supergoose, that doesn't have any RGB encoder, just direct scart RGB, or with my consolized AW that is the same, the picture is crystal clear in my opinion.

But it supports the fact that only through straight RGB is the image completely perfect. I just think that through any encoder you will see some slight interference.
