hp 840 g3
Microsoft Windows 10 (64-bit)

Good afternoon,

 

I'm trying to connect 840 G3 via displayport - hdmi cable to my monitor Samsung M7 (S32AM700UI). According to laptop description at HP website it supports DP output at 4K 60Hz, and Samsung monitor supports it to.

 

Actually, I have only 30Hz for 4K available, and 60Hz is avaialble only for 2560x1440

 

is there any way to fix that and make it work via 4K@60Hz? Or maybe there is a mistake in laptop's specs on website?

Both its specs from datasheet and manual only say it has DP port. Not mentioned anything more. With its age, the port could be DP 1.2 which would support UP TO  3840 x 2400 resolution at 60Hz.  Theory and real world would not be the same.

 

Regards.

thanks for your answer

 

I treat the statement "UP TO  3840 x 2400 resolution at 60Hz" as it should grant support of any resolution below at 60Hz. Is there any way to obtain exact DP information from HP?

I've also tried same story using HP UltraSlim Docking Station, but same story again:  4K@30Hz and any resolution below works at 60Hz

 

can it be driver problem maybe?
