I've never really understood the charm of ultrawide monitors. I dare boldly to maintain that there is such a thing as Too Wide, a point beyond which the extra visual estate becomes a waste of electricity, unless you watch the screen in pairs. I can only assume people who use ultrawide monitors live in constant terror of flanking manoeuvres and demand the maximum amount of peripheral vision. Mind you, I tend to play games with my nose about 10 centimetres from the screen. Forget being flanked - it's the prospect of snipers up ahead I'm worried about.
If you're among the people who fret excessively about flankers, I've got great news from Uncle BioWare. Forthcoming RPG Dragon Age: The Veilguard will support 21:9 ultrawide monitors. The ultrawide functionality extends to cinematics - you can disable "cinematic aspect ratios" to switch off the black bars that otherwise hem in the view. It's one of several PC-specific flourishes they've just blogged about. Have a look.
