Does CAC-1332 work with ps5 and ultrafine 5k (new model, the one support iPad Pro)?
27MD5KA is the Thunderbolt only model. You need a 27MD5KL to do USB-C input.
With the 27MD5KL, 4K60 may be possible from the PS5. If there was a way to use a custom resolution on the PS5 and the PS5 supported 5K width, then 5K39 would be possible (but this is unlikely). I’m not sure if the 27MD5KL can accept 1080p. It does support 1440p.
