HDMI Output not working following Win10 Update - "Resolution not supported, change the resolution of the external Device"

Discussion created by fireman1899 on Jan 4, 2018



My HDMI Output has stopped working on my HP Pavilion Desktop PC 570-p0XX, following I think a Win10 update?, My HDMI output is connected to a Samsung 27" Monitor and all was working fine on a res of 1920x1080 60Hz - The Samsung Monitor Model T27D590CX now says "resolution not supported, change the resolution of the external device" when connected PC HDMi to HDMi (HDMi 1/DVI PC/Samsung) - I have tested the Samsung monitor's HDMi input with another PC and all works fine at this resolution - I have changed the HDMi Cable and this doesnt solve the issue - I have updated all the latest display drivers recommended by the HP Support assistant - I have rolled back the AMD Driver to a previous version to see if this solves the issue (assume this controls the HP HDMi Output?) - I have set differant resolution outputs via the Intel HD Graphics Panel - all with no joy, It all points to the HDMi Output of the HP Pavilion which seems to be now outputting a wrong resolution the display can not identify or work with? The VGA Out is ok and works fine however if I connect the VGA and HDMI to my Monitor and set this to 1024x764 the HDMI Out works? if I then unplugg the VGA cable and leave the HDMI Connected the Samsung Monitor goes back to "Resolution not supported, change the resolution of the external Device". Can anyone help resolve?
