Hi,
I have a 2+ year old Thinkpad x250 which I've connected to an external Philips 24" monitor, using a VGA to HDMI cable - VGA from the laptop to a HDMI port on the Philips. This connection is used purely as an extender from my laptop.
This has been working perfectly till last week when I decided to replace the VGA-HDMI cable with a Mini DisplayPort to HDMI version. I thought I might as well utilise the DisplayPort on my laptop since it's there.
When the 2 devices were connected, the Philips couldn't be detected even with Display Settings on Windows 10. I had to reinstall the monitor drivers and reboot, then all was good - till I shut the lid on my x250. Upon opening up the lid, the Philips had disappeared from the extender profile and I had to repeat the setup process to get it to be detected again.
Though this was really inconvenient, I put up with this for 2 more days before this whole process failed permanently. Nothing I did could get the Philips detected. What was more surprising was that going back to the old VGA-HDMI cable now didn't work either. I repeated this whole cabling circus act with another good monitor and got nothing as well. The only connection that would work now is a VGA-VGA cable and I'm in a worse (video) position than when I first bought my x250!
I'm hoping someone out there may have seen this before and can give me some clues with troubleshooting. Thanks for whatever advice you can give me.
