Datapath VisionRGB E2S problem

Hi,

 

Just recently I've noticed a bug concerning Watchout and the abovementioned capture card:

 

With 1080p60 capture format the colour quality of the input gets diminished - the colours diverge, there are pixel-size off-colour spots and the overall perceived image quality and resolution drops.

 

The problem is only visible when the input goes through WO (with no scalling or warps enabled) - when viewed through capture card's input preview everything is fine.

 

The problem occurs with resolutions of 1080p and higher.

 

The slot is 4x, my WO version is 5.5.2 and I installed the latest card software/firmware, but it didn't help. 

 

Any ideas of how to fix the problem or where it comes from?

I have seen something like this when the WATCHOUT Display software

is started with no signal on the DataPath capture card input.

The capture card is actually locking in a wrong setting with no input to reference,

and when you actually provide a signal and call the input from WATCHOUT,

it does not adjust to the correct setting, resulting in what you describe.

Provide the input signal at power up and it usually works ok.

I usually DO provide input before startup either by usage of a switcher or EDID tool like DVI Detective and restart the display computers after every resolution changes.

I mean, I'll try that once again to make sure I did all of the above, but I think that is not going to work, though.

 

Any other random options You might think of?

Double check it, of course it may be something else,

but nothing comes to mind from past experience.

 

BTW Dataton has implemented upcoming changes to Datatpath cards it relates to this issue.

In v5 and earlier, when the card starts up,

WATCHOUT uses the DataPath interpretation of the input signal specs.

If no signal, it can lock in a low res spec and

then fail to switch up when a higher resolution signal is presented.

 

In v6, WATCHOUT will use the signal specs entered in the live video object instead.

Provided the Live Video signal defintion matches your actual signal when it later appears,

this issue will be eliminated.

 

i.e. The Datapath 'no signal at startup' issue and its after effects

has been addressed in WATCHOUT 6 with an alternate approach.
