Got a query for you on this one, @Scott...I would have a little look at the Samsung G9 as well, just to put another angle in there. It's a very expensive monitor but every single enthusiast on here drools every time we see it. A few members have it and I firmly believe some of them don't even have PCs, it's THAT nice.
I’ve not done much streaming so you might know and be able to answer this. If OP is streaming from something like the G9, would his viewers have issues watching streams / recordings with that 32:9 aspect ratio?
I’m suppose if it is a problem the aspect ratio could be tweaked in settings for streaming and then back to glorious 5120x1440 for solo gaming.
