Triples with different sized screens

[MadKreator]

Trying to help someone in the helios discord, he had triples setup 3x 27” monitors, running just fine. Changed the center monitor out to a 34” and now even though helios is calculating the total size correctly, when he runs dcs it cuts off about 15-20% of the farthest right screen.. Any had any issues with running triples with a different sized center monitor? I’m kind of at a loss. ( the pixel count differences don’t seem to match up to what is being cutoff visually) monitors are 2x 2560x1440 and 1x 3440x1440

You can get into an issue with the graphics card's maximum supported 3D application resolution

You're trying to export a resolution of 8560x1440 which is now more than most graphics card can support.
As a educated guess I'd say you're losing 880pixels off the edge.

3x1440p monitors are 7680x1440

eg
GTX1080/RTX2080ti/RTX3090 Max res is 7680x4320

7900XTX max resolution is 7680x4320

In fact I can't find a single graphics card that will do more, seems to be a standard, equivalent to 2x4K displays.

  Awesome, thank you! We’ve been fighting it for days lol I had no idea about a hard limit in the GPU. This is kind of what we were thinking, that somewhere its exceeding a max allowed resolution but didn’t know where.  When he dropped the res down to 7680x1440 and re-centered in the monitor setup manually, the blank area split evenly between both sides of the monitor..  yes he was losing 880 pixels exactly.

Hi, I am having the same issue, my card is RTX 4070 super. The extrange thing is that at some stage it worked okay (rendered across full 3 monitors) and today the black bar on the far right appeared again. Any clue why it was working ok before and how to revert? thanks!
