In a previous post I mentioned that I was having problems making my new Samsung 4k UHD monitor work at full resolution.
I ordered a new Gigabyte GEFORCE GTX 660 video card from newegg, removed the old video card, and now have three monitors plugged directly into this video card.
My center monitor is the new Samsung display running at 3840×2160 on the display port, and the left and right monitors are each HP Pavillion 22bw monitors running 1920×1080 using the DVI ports. The one strange thing is that Windows recognizes the dot pitch on the Samsung monitor and attempts to make things larger than I’d like. It is a configuration option to make text larger or smaller by following the link on the screen resolution dialog and I have moved the slider one notch smaller from the center.
