It seems that that the x5 won't play disney plus in 4k but i can can on my u5 

are you using same app version?

Yes

I use the one that was posted a while ago that you need to download 

Should i try this i see it come out 9 days ago 

It won't hurt, but I don't think that is the issue.

Are you connected to same TV (direct or though receiver or other device) ?  Are they wired, or wireless ?   If Disney plus thinks it doesn't have enough bandwidth, it will scale down.  It will do the same if HDCP is not detected and it thinks you are going through some intermediate device.

Maybe try swapping the HDMI cable.  if the HDMI cable is marginal, it may not be able to properly detect HDCP which would inhibit 4k.

 

 

I use the same hdmi in my u5 and i get 4k and both are  wireless 

And using the same tv and the hdmi card is going rightbto the tv 

And only Disney plus parmount plus i have no problems with 4k 

Which X5 do you have ?  The Newer AX-C model, or the older one 64/128AI with AC WiFi ?

The Wifi is not the same on both devices 🙂  Before ruling out a potential bandwidth issue (as perceived by Disney Plus app), I'd say if possible, try to use a cable, instead of WiFi.  Not saying you have a bandwidth issue, but I have no clue what algorithm Disney is using to decide one way or another.   Just saying.

 

 

 

I have the new one the c power and unfortunately i can do wireless because my modem is in the living room and the box is in the bedroom 

then take it to living room and wire it to rule out wifi
