KM My thoughts are we must buy and test current cards to see if they work.
Unfortunately, at some point someone has to buy expensive equipment and see if it works.
The best way is to have companies / people who do this for a living (reviewing hardware) review to see if it's bad or not.
Problem is, we've yet to determine what reliably causes the issue. PWM, Dithering are big candidates as well as others. But then what causes the dithering? Motherboard? Graphics unit? Montitor? Some of the above?
There have been some ideas already that haven't really panned out so I'm interested in hearing any ideas that I could setup / host.
In any case, The GeForce GTX 750Ti works well for me (dithering disabled under linux) with a 8-bit monitor 🙂
