Just wondering, Is stress testing the server with just 1 4K monitor at the office, the same as having all the displays connected onsite (3 4K outs, 1 1080P control monitor out)?

Wouldn't the computer know it's not really sending the data out of the display ports/HDMI ports and thus have a different performance reading than when it's live in action with everything connected?

Is there a way to trick the server into thinking its onsite to get a real stress test?

Hi,
You can't do exactly what the software (including OpenGL - graphics drivers layers + windows display layers) / hardware would do with the displays connected.
However if you activate the "Show Desktop Windows" on all your Video Outputs in MadMapper, it will force MadMapper to render the content of the displays, so until you only have only one GPU, it just really approximate performances you'll get with the other displays connected

you can buy hardware HDMI edid emulators, the system will think there a displays connected.
