Heads up on display setup

[Santacarl]

Hey All....

I ran into a problem last night when I fired up the show for the first time.  I have several small matrices =<500 pixels.  When I scrolled text or threw up a small gif on any of them I got gibberish or no picture....

It turns out that, for several years, I've used the "zig" feature on my F16v3's....while 'feeding' them show data with the FPP.

Last night was a nightmare.  Show was near disaster...so to speak.  When the sequence is built around a talking face and there is no talking face to be seen that kind of spoils the deal.

Although I'd made no changes to my two F16V3's (neither firmware or settings) since last season I did some testing to see if somehow my pixels were still in correct order.  I found that the "zig" didn't appear to work on either F16V3 any longer because on vertical matrices the next pixel on the second column jumped to the bottom instead of being adjacent to the top pixel on the first column.

Scratching my head I could understand why 1 F16V3 might have gotten off or 'threw' its setup to zig....but both F16V3's?  Not likely...

So out of curiosity I set my zigs to 0 to eliminate them on the controllers and BANG everything worked perfectly.

Since I haven't upgraded firmware nor changed any settings on the F16V3's the only thing I could think of was something going on with the FPP.  Then I recalled upgrading my FPP to version 6.xx and I wonder maybe if there is something in the firmware for FPP that 'senses' a matrix and just assumes it needs to zig?

All that kind of thing is "above my pay grade" and ability to understand so I'll just throw this experience out to share with others in case they run into a similar issue.

Technology improvements are wonderful....until they suddenly don't work as you expect. 

All that said...not sure why the same fseq file from last year rendered in 21 a version of XL worked when I replaced the one updated with one of the "22" versions of XL....  Might be a combination of things causing this....

All this stuff hurts my 'punkin' head.....
