Are there many modern AAA titles that don't support the resolution
@Azrael1 ?
Yeah some new games don't fully support it so the aspect ratio is wrong. These can be fixed sometimes via widescreen forum fixes. However if you like PUBG do not buy the monitor unless you are going to run it at non ultra wide 32 9. That game clips your view. The devs did it on purpose as they thought it was an unfair advantage -at one time you could alter it perfectly.
Games that look stunning compared to normal 4k and 21 9 I play and love are
Destiny 2
Forza Horizon 4 ( I have an oled older gen 4k TV and still prefer it on the 32 9 )
Halo Collection ( really impressed they supported this res )
Breath of the wild ( Emulation ) - its truly worth owning one of these alone to play that
Mario Kart ( emulation ) -
Mortal Kombat 11
Read dead redemption 2
Battlefield/battlefront Series
The thing is fully supported games has spoiled it for me to the extent the alienware 34 IPS is just exclusively for the kid
If you play a lot of console ports etc the majority of them do not support 32-9. The same goes with indie games - better off with a normal 4k imho.
