V2 HDMI to VGA Conversion

Hi all.

Just found that DIGITAL-VIDEO-VGA conversion of Vampire V2 video output several vertical lines from the left are missing.

For example, 800x600 becomes something like 794x600. And it is applicable to any resolution.

I've tried a 6 different adapters and all of them produces noncomplete picture. So I don't think that adapter is a problem.

Is it possible to fix this?

Thanks.

Honestly never tried converting the H.D.M.I output to anything other than that, but for the V2 which can output many different and odd  resolutions and for it to work on modern monitors I have used device like this, which normalizes the output resolution.
 
  EXTERNAL LINK   
  This basically scales any input resolution the V2 can output to a set output resolution, perhaps from there you can connect you VGA converter.
 
  This also has SCART connector, so if you have a European SCART adapter for the RGB output you can toggle between RGB and DIGITAL-VIDEO output with this device too.

I use a cheap random aliexpress converter, and it's working just fine.
