Hello,

I am having trouble connecting an additional monitor to my laptop and would appreciate support.

Here's the situation;

- Laptop is a Toshiba Satellite M840. It has i5 3210M processor and AMD Radeon HD 7600M graphics. It runs Windows 10 Home v 1709, OS 16299.334 on a 64-bit platform.

- External monitor is ASUS VX229 from June 2016. It is not an old monitor but it does not have HDMI functionality.

- Until now, this specific combination of laptop and external monitor has functioned well together since the monitor was purchased a year ago. There have been absolutely no issues, simply plug-and-play with the VGA cable.

- The monitor was not in use during March, and after re-activating it in early April, we realized the connection with the PC is no longer functional.

- The external monitor is powered on and functioning - tested by pushing built-in buttons to change settings etc.

- The VGA cable is fully connected in both laptop and external monitor; when removing/attaching the VGA cable the laptop will register by playing a sound and the external monitor will flicker and change resolution. But no picture on external monitor!
- I've initially used Windows 10 function to update drivers (feedback was that all drivers were up to date) and subsequently downloaded the dedicated AMD desktop app which indeed updated the graphics card driver last night. The current driver version is 15.201.1151.1008 and the previous version seems to have been 15.200.1062.1004.

- The laptop has been rebooted multiple times

- In the "Display" section of control center, I continue getting the error "Didn’t detect another display".

- I've tried to roll back the driver for the graphics card which did not resolve the situation; subsequently reverted to the newest driver.

- AMD Catalyst Control Center can detect the monitor, including correct naming ("VX229") so definitely there is some sort of connection, just still no picture...

At this point I'm running out of ideas... Help appreciated!

Best Regards,

Rasmus
