Just a single 49" 32:9 ultra wide - effectively 2x 1440p 27" monitors side by side. It's a MASSIVE improvement over having two bezels lined up straight ahead and always having my head turned to one side or the other, or having my desk set up asymmetrically with a single monitor head on and one off to the side.

It's rare I need two full 16:9 windows side by side - so for work, 90% of the time I've got a 16:9 frame centered, and extra content on the sides (outlook and teams for instance). Window snapping via Microsoft Powertoys - Fancyzones makes this so dead simple, so it's a quick keystroke to change the snapping zones and then I can do 2 windows side by side when I need it, 2 side by side+my teams, or 3 side by side.
And for play, let me tell you - games and anamorphic films look SO GOOD on this thing. Absolutely LOVE this monitor.
