I had one of these Sapphire adapter cables (purchased from Amazon UK) connecting my third Samsung SyncMaster 940 BF (1280 x 1024 resolution) to my Sapphire Radeon HD 6850 1GB:
This worked fine - the cable was instantly seen by Windows 7, and I was able to set up Eyefinity across my 3 identical monitors.
After about 4 days of use - mostly playing HalfLife 2 and Counter Strike Source in Eyefinity mode - the game went jittery (across all 3 screens) and I had to re-boot.
After booting - the cable is no longer recognised by Windows. Removing it and replacing it and rebooting has no effect.
Is this a known issue?
Is it likely that the cable is dead or the DisplayPort in the graphics card?
Is it worth me getting a replacement, or would I be better choosing something else instead? There seems to be some difference of opinion on the forum reading through some related posts, but I can't find this particular cable referenced.
Many thanks.
