Mapping gone when adding delay to a Projector

[Wieger]

Hi,

I had this problem during a show last friday. Unfortunately I can't reproduce the problem at home with just some computer screens.

The setup was with two projectors (Barco RLM-W6), one was connected through HDMI directly and the other one through a BlackMagic Design converter set (HDMI>SDI). The maximum signal I could get from the latter was full HD at 30hz due to the HD-SDI bandwidth limit, the first one was at 1080p 60hz. All running from a Windows 10 (1809) laptop with a Quadro p2000 graphics card, running the latest Resolume Arena 6.1.0

The projector connected using the converter set had a delay obviously so I wanted to add a delay to the first one to get them sync. But when i tried adding delay, the mapping for that projector was gone. The mapping on the other projector without added delay stayed intact.
Because of time pressure i couldn't get to the bottom of it and just accepted the delay. Nevertheless i thought I should mention it here.
Maybe someone recognizes this?

All the best,
Wieger

We've been working on an issue where enabling delay for an output, would make the output texture resize.
This only happens if the output has Scaling enabled in Windows display preferences to something other than 100%.
Doesn't quite sound like the "mapping gone", but could appear as such.

Did your display have scaling set to something other than 100%?
Were the slice transformations still visible in the Advanced output window?
