Envy Cannot find my Westinghouse Display

[Bemo234]

My Envy will not recognize my second display. The same display still works perfect with my HP Pavilion. I have updated my drivers and cannot seem to find a driver for Westinghouse.

Your laptop does not have any outputs but a HDMI, so assuming that is how you connected the monitor.  What input is being used on the monitor?

There should be no need for a driver to allow the monitor to function.

why post laptops to desktop forum? go back to blue link left and this time click lap.

the port need to be turned on

your manual on this fake desktop (lol) covers how to turn on the external GPU port,   a Fn + fx key pair.

it is in your manual at HP.com RTM

what is the cable there, HMDI ,VGA, DP or DVI?  (manual shows VGA)

the hot key works like this.

internal, external , both and auto , on most laptops on earth and fn keys NOT THE SAME on all.

the auto can fail so we use both or external. see>? 

ask anyone like me with protectors used 1000 of times this, bingo, turn it on first with the HOT KEy

the key on mine is F4 is IT,  the 2 keys at once pushed Fn+ F4 called presentation mode by HP and has key ion of a screen.

tell helper first

my PC is a laptop (posted to desktops in error)

and model you did

and is 10years old  with that old 5:4 screen, not not 16:9 .

and has VGA port only

and you have not read the manual too see Fn+F4, but oops that old manual skipped those facts, yup , an HP error that.

there is one HP page  at HP those the keys by icon and not the F number.

wow, is that bad.  F4 is it I think and is on all mine here,  HP8540w, retired in the attic for ever.

the book does not cover at all how to use VGA port,  I read it for you and does not. (must be other books that do)
