This has been an on/off issue since I got this nearly 3 years ago.

I'm seeing gradients and banding on videos, and images I'm editing. Initially it was only blacks that were severely crushed, and after various graphics card updates, it improved.

However, recently it seems to have gotten worse, with any gradient colours looking blocky. What can I do to resolve this? A machine with these specs should not look this bad!

Thanks in advance for any help.
