A short while ago my monitor started displaying random flickering blue dots and lines on very dark backgrounds during videos. I took a sample shot of one of the backgrounds from a video and stretched it as my wallpaper. This then displayed the flickering dots and lines symptoms on my desktop too.
After trawling the internet I finally found a suggestion that worked, possible faulty DVI cable. Luckily I had a spare DVI cable and luckily enough that fixed the issue! Fast forward a few weeks: I am now getting red (instead of blue) flickering dots and lines during videos. I have even observed these symptoms occasionally in videogames now too, with Chaos on Deponia being a prime case during the harbour scene.
Has anyone ever had these symptoms and were able to cure them? I've ordered a new DVI cable to see if it's just this DVI cable too, but I am thinking it's probably the worst case and the DVI connection in my monitor is on it's way out... It's a Dell 2407WFP and I've had a good 5 or so years use out of it so I can't complain at £100 a year. I've ordered a new Asus 27 1440p, but I would like to salvage this as a secondary if possible as it is still going strong!

. I've ordered another monitor too so I'll be able to test if that's the issue. I'll be upgrading my graphics card soon as well.
