Hi Everyone.
Just bought a new LG Ultra wide monitor today. Love it to bits, however I am having an issue with displayport.
Displayport works and displays an image without issue, however if I were to turn off the monitor or simply change source... if I flick back or turn on the monitor again while the PC is still on... it displays "no signal". I would have to turn the computer off completely or reset it for the monitor to get a signal again. This behaviour does not happen on HDMI - I can turn off the monitor while my PC is still on, and switch it back on without issues.
However. I decided to grab my brothers computer which he uses DP on, and also use his expensive Amphenol DP cable (full size DP), there are absolutely no issues and it behaves as normal - ie. if I switch off the monitor and switch it on again while PC is running - it receives signal and comes out of sleep mode or whatever.
I have never used DP before so I don't know what I'm doing wrong here. The cable I am using is the one that came with my Viewsonic 4K monitor which was donated to mum. It's a DP to Mini DP because my HD6870 card only has mini DP, and not full size DP like my brothers PC.
Could it be a cheap cable issue?
Thanks.

But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
