Graphics card - firepro v4900 no overclocking or anything.
Amd Catalyst driver - 8.982.2, tried .3 but it wasn't stable for me and I reinstalled .2
Operating System - windows 7 64bit.
10 bit problem, I'm testing it on ramp.psd file, when I open file it shows in 10 bit, when I make any action (brush stroke or just zoom in or out) it shows in 8 bit (visible banding) to see 10bit again I need to move image.. just slightly and it works, and only this way it works, obviously this is wrong.
Applications - Photoshop cs6
cpu - 2500k
display - Nec PA271W
motherboard - asrock z68 extreme4 gen3
system memory - 16gb samsung

additional details - everything works fine besides 10bit issues which is only reason I bought this videocard for.
