Review
I bought this when the item was incorrectly listed as having HDMI and display port connectors.I was able to get a price adjustment from the seller and purchased an "active display port to DVI-D" adapter and was able to get full resolution with no dead pixels.
Note to use this monitor w/ display port, the display port needs to be able to drive 2560x1440.
The monitor does work well but only has brightness controls and can only display in 2560x1440 (it doesn't have scaler hardware).
I did not try the monitor with windows but the EDID reported to Linux was wrong,
I used the following to get the monitor working on linux:
xrandr --newmode "2560x1440_codesim" 241.50 2560 2608 2640 2720 1440 1443 1448 1481 +hsync -vsync
xrandr --addmode DP1 "2560x1440_codesim"
xrandr --output DP1 --left-of LVDS1
DP1 is the name of the display port interface on the laptop and LVDSI is laptop display.
Running "xrandr" with no options will display this information.
Four stars since the monitor did not have a scaler card.
