I am having quite an upsetting problem with a new monitor I have bought and wonder if anyone can help me out.
I do graphics work and so I needed to purchase a larger monitor because I was killing my eyes on the 13inch new MacBook screen.
I needed something affordable and so did some research and stumbled upon the BenQ2220HD monitor. Very good reviews, reliable brand, etc.
Somehow it didn't come with a DVI-D cable so had to purchase it. Purchased a 5m cable, thought this was the norm and plugged it in. The monitor was going crazy, flashes, grey noise, appearing here and there, I tried setting different resolutions, funny thing is that once you got it working it would be perfect but then sometimes would start misbehaving again, or if I turned the screen off and back on again, it would have the grey noise, and take a while return to normal, after much coaxing from me.
Then someone told me the cable is too long, the signal is travelling too far between points so purchased a 1m cable. SO I thought this was my answer. When I plugged it in it was much more stable than with the 5m cable. The right resolution came up straight away and seemed to be alright. So started to play with it, and then noticed these flickering pixels appearing on certain colours, lines appearing where grey bars in the browser were, all sorts of flickers. Sometimes it even goes back to the grey noise, the whole screen. On the whole I guess it is more stable, but when it wants to, and I get the flickering pixels all the time (a weird thing which I didn't have with the 5m cable once I got it to work.)
The monitor came with a disk with cat, inf, and some other file type, must be drivers? Well I can't use them as I have the mac. I tried putting the disk in and seeing if there was anything the mac could read but nothing.
I was thinking, if I install Windows using Bootcamp on here, might that cure the problem?
Sorry for the really drawn out explanation -- it's just, there are lots of things to say about the problem.
Thank you in advance for any help at all; I'm going crazy over this.
