Screenshots black

Hi, for a couple of weeks now the screenshots are black - this is using a PC linked to the TV with display on both screens. I recall a similar issue about a year ago which was subsequently fixed. Help would be appreciated.

I am using the same setup and my screenshots are fine, check your graphics drivers that may be the issue.

Thanks - all drivers are up to date. I checked and when taking a photo with the ZMA I get a clean (no HUD) copy and a black copy (presumably the HUD version) in my pictures file. When I change to monitor to just the TV (through the laptop) , and take a photo I get a HUD version and a black (presumably clean) copy. Odd…
