I'm pretty sure the AW3420DW is capable of 1440 with HDMI. Does the PS5 video settings allow you to choose 50Hz? The online AW3420DW User's Guide page 14 states that the Maximum preset resolution for its HDMI 1.4 is 3440x1440 50Hz. Page 15 goes on to show HDMI display modes =1280x720p 50Hz1280x720p 60Hz1920x1080p 50Hz1920x1080p 60Hz3440x1440 50Hz
Now that the PS5 supports 1440p, has anyone had any luck getting it to work on their AW3420DW? When I check the PS5 settings it says it's not supported but I'm pretty sure the AW3420DW is capable of 1440 with HDMI.
AW3420DW, PS5 1440p support?
