Samsung Dex can't display on monitor

I'm using Samsung Note10+ with DEX on 2 Dell monitors. On one monitor, it works fine. However on another monitor, it's telling me that my monitor or tv isn't working correctly or resolution isn't support by samsung dex. 

 

However these 2 monitors support to 1080p. 

 

This monitor works fine:

this monitor is giving me the msg:

https://www.dell.com/en-sg/shop/dell-27-monitor-e2720hs/apd/210-auym/monitors-monitor-accessories

 

Both supports 1080p. Can't be the adaptor because i've swap both of them and it is still the same. 

 

can anybody help?
