My nMP came with D500 cards. Since I hardly could pay for it at all I kept my Samsung 245b Monitor. It is almost 7 years old but made no problems whatsoever with my previous oMP. It shows 1200 x1920 (with 60 Hz as far as I know) and is connected to the nMP by an adaptor Mini DisplayPort (TB) to DVI. Now I unexpectedly notice that when I scroll up and down or left and right there are parts of the pictures shaking for a moment. If I move a window, the border line does not move in one piece but some parts of it move slower than the rest and for a moment there are "steps". Is my monitor "too old" for the D500 (difficult to imagine...) or could it be a problem of the Graphic Cards??? I could not find in the support of Samsung any new Firmware for that display and changing the resolution to a lower one than 1200 x 1920 does not take the trembling away. Thank you in advance for any help to solve this!
