External Video Quality XT3?

[trashcaneron]

My external monitor is set to FHD. 

When I'm reviewing footage on my external monitor while it's plugged into camera, the quality and the color is correct. LUTs appear as they do on my computer, etc. 

When I'm recording footage or in standby mode, my external monitor's quality is reduced and isn't as good. Why is that? That means that auditioning LUTs on the external monitor isn't really a 1-to-1. It also means that focus assist and peaking isn't correct either. Punching in yields an extremely soft image in certain situations. I can punch in on the playback video and it's sharp as a tack. Super weird. 

I've turned off HDMI Info Display, which has made it a little better, but it's still soft and not color accurate. So I'm guessing this is some kind of setting that I need to change? Or a massive flaw in the Fuji XT3?

Would forcing the EDID to 4k help? The external monitor can receive 4k but for some reason the Xt3 is throwing the settings mismatch error if I set it to 4k via the XT3 menu settings. 

Any help here would be massive!
