I changed hz refresh 24, 60, 59 . resolution 1080 . I use a rx 570 video card latest drivers .

HDMI to monitor but not projector

Thanks. Drivers are up to date. Dell are now suggesting I need a new motherboard, which seems a bit extreme! I have now discovered that if I switch on either laptop or projector when connected by HDMI, it will owrk. But there is no 'plug and play' with the
projector, though there is with a monitor.

So at least I have a workaround, and that's good enough, I guess.

Thanks for your help.

Richard.

 

HDMI to monitor but not projector

I have a Dell XPS laptop with HDMI output. Suddenly, and for no obvious reason, it wiil no longer recognise my Dell projector. However, it will still recognise an external monitor and a HDTV. The projector is recognised by my old laptop via HDMI and VGA.
So the HDMI on each machine works; they just don't work together any more. Any ideas?

 

2nd monitor not displaying correct resolution

First monitor is a IPS 2460 x1440 resolution at 60 hertz, and my 2nd monitor, should be 2460x1440 resolution at 144 hertz (benq XL2730Z ) gaming monitor;however, it is only displaying
1920x1080 A 60hz as the recommended option.

my graphics card is a little dated but it should still work? has been updated to latest

AMD Radeon HD 6900 Series

crossfire

ive tried using a dual dvi and hdmi, neither helps to solve the issue, also tried using different hdmi incase one is defective..

please help.. S:
