Warkings :
Is the SAMSUNG B550 Series S23B550V ToC 23" 2ms GTG HDMI*2 Widescreen LED Monitor 250 cd/m2 1000:1( My current moniter) better than the Asus VS239H-P 23.0" Monitor
If you already own the monitor keep it.
But if you are going for a high end build i highly reccommend going for an IPS panel like i linked. It makes a huge difference when switching over from a TN panel to an IPS panel in my experience anyway.
And yes, the one i chose is one model above the one you chose
Its basically the same monitor but the IPS version.
