apologies in advance for poor heading, cant think of a proper title.
I have a 3 monitor setup, from left to right lets number them 1,2 and 3.
yesterday monitor 1 developed a flicker, every 2-5 seconds the monitor would go blank, stay blank for 2-5 seconds then the picture would return.
That monitor is only 3 months old, so I doubted it was at fault, so my first thought was the cabling.
So, as any logical person would try I thought I would swap the cables around with another monitor and see if the flicker follows the cable or stays with the monitor, make sense right ?
WRONG.
In any other part of the world, in any other universe that makes sense, but in my room, at that time - we had a Douglas Adams moment.
swapping the cables between monitor 1 and 3 did not reverse the screens over like it shoulda done in my head. The display stayed 1,2 and 3. like it did before. so how does that help me trace the fault ?
The flicker disappeared after changing the cabling so it so not an issue now, guess it must have been a dodgy connection after all
my questions are:
1) with three monitors all the same make and model, how did windows/nvidea or the gpu know that I had swapped the cables over for it to have adjusted the output from the gpu to compensate and keep the display at the 1,2 and 3 position?
2) windows/nvidea/the gpu can 'detect' the make and model of a connected monitor so info clearly flows back down the hdmi cable, do monitors also have an individually identifying serial number that seperates them further from each other ? ( this may be the answer to the first question )
3) I have very cheap, 5 meter long hdmi cable connecting that particular monitor, I'm no electrician so please forgive my poor description, but can a cheap long cable like this build up 'resistance' or be influenced by poor shielding from other electrical sources and cause this type of problem?
thanks for taking the time to read all of my waffle
