Extron 201 rxi problem

[schnuth]

Hi all. I recently picked up a Extron RGB 201 Rxi to add to my setup and I'm having some difficulty getting it to display correctly. I'm getting some bending at the top of the image.

According to the manual setting the SERR dipswitch is supposed to eliminate it, but this does nothing for me. Setting DDSP to turn off processing makes it go away, but that's no good either for my needs.

Any idea what I'm doing wrong? I tried different cables, two different PVMs, and different consoles all with the same results. Would the internal dip switches or jumpers need to be changed? I tried opening my extron to take a look but I could not get the top to budge after taking out the screws. I'm sure it's something dumb, but I can not figure this out.

My setup is console (SNES pictured)>arcadeforge sync strike via SCART>Extron 201 via VGA>BNC to PVM.

Any help would be appreciated. Thanks in advance!

After Googling this problem for the past few hours, I suspect my Extron might be to blame. I might've gotten a bad unit. If anyone has a different idea though I'm all ears.

does the distortion follow your picture when you move it with the vertical adjustment knob?

It does. It stays consistent across the top of the image no matter where you move it on screen. Which is a bummer since this was why I bought the unit. Making these adjustments on my PVM 1943 MD involves opening the case and adjusting pots since there isn't a on screen display.

I don't know if the Extron is for you if your sole purpose is to make those adjustments via the Extron instead of via the pots. I know with mine to get rid of that top bend I need SERR and DDSP on (think so at least - I'll double check) - which doing that disables the ability to shift the image with the Extron's dials. I've spoke to a couple friends and they find the same as me...

Thanks for checking, I appreciate it. I have a feeling that the SERR function on my Extron might not work. Ah well.

So I got myself a different Extron, a RGB 203 Rxi this time, and I'm having the same exact problem as I did with my first unit. The same distortion on the top of the image, which goes away when you flip DDSP on. Turning SERR on the new unit dosen't have any effect either. So I think it's safe to assume the Extron isn't to blame, could it be something with the Sync Strike?

The terminology of ADSP and DDSP is confusing. DDSP is using the sync signal of the source and ADSP is using the Extron's regenerated sync. So if you are saying you observe the problem with DDSP on (thus ADSP off), I wouldn't necessarily be surprised.

In my experiences with the Extron devices, I ran into problems not dissimilar to yours when using ADSP. It allowed more tuning of the signal but ultimately led to minor visual defects.

You haven't mentioned -- for what purpose do you need ADSP?

[schnuth]

As I mentioned I was hoping to use ADSP to recenter the image easily on my older PVMs. Would it be possible to use the two units together to get a stable image that can be positioned with the Extron?

I originally got an Rxi to do exactly this, until I realized my PVM-1954Q had a service menu that allows this. Have you ruled that out as an option?

As I mentioned above it's an old PVM without an on screen display. To adjust the image you need to take off the case and adjust the pots on the inside. I was hoping this would be an easy solution.

Got it, sorry!

Got it, sorry!

It's all good. Thanks for the suggestions, this is just becoming much more frustrating then I anticipated.
