Sir, I purchased your touch Monitor DELL S2240T and I was excited after purchasing it but when I connected it to my laptop HDMI port, I am very much disappointed because the screen display is very dull. White is not really white and bright and black is looks like gray all the time. I tried many settings, for many hours I changed its brightness and contrast but I can't achieve my desired mode. If I compare it to my laptop display the quality looks very bad as if I have purchased very old chinese phone. Please suggest me solution. I am highly disappointed with it.
