Hi
@PARTICIPANTOBSEWhat error you see on the screen? Is it the one who in the end says " current resolution isn't supported by DEX" and have option to press OK and still use it or its different error?
It might be due to your projectors resolution is too low,
Samsung DeX supports the following resolutions: -WQHD: 2560 x 1440, 16:9 -FHD: 1920 x 1080, 16:9- HD+: 1600 x 900
It might be due to fact that projectors resolution isn't supported by DEX.
