XRGB-2 Plus Issue

[Skips]

So i managed to get an XRGB-2 Plus off eBay for an OK price this week. I get it all connected and it seems to have a stability issue with some slight garbage.

Video of the issue - https://www.youtube.com/watch?v=c8_Q6tF ... e=youtu.be

It does this even when nothing is plugged into the XRGB so its not the JP21 cable I made. Playing with the DCT options alters it slightly but does nothing to fix it. Has anyone else experienced this and know how to fix it or should I contact the guy for a return?

*edit* Its not the monitor either, it does the same exact thing on both LCD's and my old CRT monitor.

It's nothing if only the OSD is affected, my XRGB-2 and XRGB-3 OSD show the same thing depending on the source and settings.
As long as the actual game image is stable you're fine.

The 2 Plus though isn't the best when it comes to image stability, later you may experience actual game image stability issues on the top part (trembling) but again that depends on the source.
The 2 and 3 feature an AFC option to correct his, but not the 2 Plus.

You can try to activate the Super Mode, there might be more settings there, but I doubt there's an 'hidden' AFC (nobody ever confirmed the contents of the 2 Plus's super mode though, so I can't confirm...)

To activate the super mode:

Unplug the unit for 10 seconds, plug the AC adaptor back in, press SELECT+MENU once then...
↑ ↑ ↓ ↓ ← → ← → SELECT, MENU

Took me a few tries to do it on my 2 but it was worth it.

Yeah its doing it in the game too, its just most noticeable on the OSD. I have a couple friends with it and they said theirs does not do this. Ill see what the super mode has to offer though.

For me the picture of 2plus was alway a bit unstable. More than on the XRGB-2 or 3.

Again it really depends on the source and maybe your display as well, I don't know if your friends use the same sources but the trembling is very common on the 2 Plus, it's not a 'defect'.
The device just wasn't designed to handle frequencies too far-off 60.00Hz and is very sensitive.

Like Fudoh just said, I had one for a few weeks some years ago, and I've been through the same thing, almost all consoles showed that trembling and it couldn't handle most arcade pcb's.
This is why the 2 or 3 are usually recommended, even the 1 is much more stable.

The 2 Plus's picture quality is excellent though, sexiest single-field linedoubling I've seen. ^^

I think stable was the wrong word for me to use. The problem is more along the lines of pixels flickering in and out of place (white pixels will flicker black and black ones white). The image itself is not wavy.

Also it looks like supermode had nothing to correct the issue.

What's more in the super mode compared to the default OSD ?

It does it on any display plugged into and even without a game console connected to it.

Scan - VGA or XGA
H_Start
H_End
V_Start
V_End
HDWidth
Sharp_D
Sharp_M
RGBMODE - C1, C2, or C3

Indeed I don't see what could help there.

Maybe it's some kind of signal interference... from the PSU or the VGA output ?

Have you tried resetting it ?

When the unit if off, hold the left (←) and right (→) arrow buttons on the unit (not remote) and press the power button.

Yup even after the reset it still does it. I also changed out the vga cable with a better one and no luck. I heard its common for these things to need their capacitors changed but since I am protected by eBay still I don't want to open it unless I know that would fix it.

Here is another video that shows the flickering off a bit better. It really looks way different that what the waviness from a sync issue would be. Anything connected to it has the same problem (image appears to be stable) but its just easiest to see on the OSD.

Are you positive it's doing it on the actual game image too ? From the little of the game we see on your videos it doesn't seem to..

I've seen the same happen on the OSD of both the 2 and 3 too, but nothing ingame.

Yup, its just harder to see. It happens randomly all over the image. Its most noticeable on white and black lines which is why I am using the OSD as an example.

So it looks like I was wrong. Its only certain areas of the screen doing it. Changing the DTC value will also change the location of the effected areas. Here is a video that clearly shows how some areas are ok and some are not. These bad areas seem to extend vertically in the picture top to bottom. So you can correct some areas but not all. The menu does not change but I would not care about that if the games would work correctly.

I am starting to think the pixel clock is not syncing correctly in this thing.

[Xyga]

Much better video. I've seen that kind of behavior but not so localized, that was coming from the source (a 'bad' Saturn), both my XRGB's couldn't do much to fix it of course.

If by chance it is only a matter of finding the right DTC value, you can try on a completely (or almost) completely black screen with the XRGB's brightness cranked up so it shows a grayish picture rather than black.
This usually reveals the signal faults in the displayed image.

When you see it you can try again the DTC slider until you find the most stable value.

There is no most stable value. I've already tried every DTC value, it just moves which section is effected. The lower the value is the least amount of areas are effected except they are larger areas. The higher the value is the areas become smaller but much more frequent. I am probably going to request a return because this thing can't be functioning correctly. I could understand if it were the whole screen or one particular game console but its like this with every single one in the same exact areas. I have read that people have had similar issues with the menus but the video from a device was just fine. I'm willing to toss the menu up to functioning as it should but this problem with the games cant be.

[Fudoh]

what I see in the video is what I would expect from a 2plus.

Is this running on a LCD ? The columns (as in vertical bars) where this happens are usually the ones where the phase/clock setting of the display doesn't match the source. Or at least this is what pronounces the problem even more.

You said you tried it on a CRT ? Same problem in the same areas ?

Yup, it does it on my old CRT monitor as well in the same areas. It does not seem to matter what type of display I use or how old/new it is, it is consistent. The areas that are not having the problem (which will change depending on the DCT setting) are perfectly stable.

Maybe it's a matter of positioning, I mean for instance I've experienced serious issues with the 2 because the output image was shifted too far left. Moving it just two steps right completely fixed everything.

With those devices the horizontal position seems to be crucial for timings (maybe the vertical too, dunno).
