I know I don't have what is classed as a "new" TFT anymore. But my VX910 has lasted a long time, and still performs. However, I have been sufering lately with black wavey lines moving down the screen (kind of like a slow CRT refresh rate). Now I know one or two others who had this, and it could be seen against the ocUK blue background.
However, I have just done a bit of a PC cleanup today, and put the latest nVidia drivers on. Now I used to run my screens with "nVidia scaling" selected. I since have reverted back to using the "display adapter" for scaling and the black lines have gone!
When I selected nVidia scaling they re-appear.
So perhaps worth trying if anyone else has this problem.
Cheers.
