ok I'll borrow and check that.
for now as shown in image below windows recognize second monitor connected but monitor show "check signal cable" message then turn off :


this might help me, can you tell me this hardware config info for my laptop HDMI port ?
I think my Intel UHD 630 platform id is : 0x3E9B0000 is it correct ?
but I don't know hdmi port : Index,Bus Id, Pipe I have no success finding these info 😑

Hi, yes I did all typical ways, no success. I'm a programmer and familiar with how windows work with external displays.
as I don't have access to asus support centers, don't know how to get this hardware details. these can really help me figure the exact problem :
Intel UHD 630 platform id, hdmi port : Index,Bus Id, Pipe
