Hi ,

I have a dell vostro has two screens, one is dectected in device manager and working, the other is a acer k222hql monitor, connected via DVI, then it goes into a spiller, which makes the dvi into hdmi and then goes into the pc , there is a orange light on the monitor, i had tried lots on troubleshooting remotely, I have updated the graphics drivers bois etc , it was working before then it stopped working. Can anyone help please ? What I can do next ? 
thank you - an answer before Monday , would be great if possible

 

 This is the extra  screen, which DVI from the monitor , then into a splitter to HDMI into the PC.

the other screen is VGA which is working and detected.

the second screen, which press “detect” it can’t find another screen attached but it’s all connected apart from the orange light on the acer monitor

 

how do I access the OSD on the acer screen , maybe inputs have changed? I tried the buttons on the sceeen but the menu doesn’t show (unless I’m doing it incorrectly )

 

any help before Monday would be great 

 

thank you so much.

 

look forward to hearing from you.
