if you added a tuner card to your computer instead you would have a wider assortment of monitor choices. if you insist on a monitor-based tuner then your choices will be limited.
i don't think you will find an ips-led-tuner monitor for awhile. even if you do your selections will be very limited.
if they look similar then they most likely are. if you are set on picking one of those two monitors then just do a quick google seach for model ###### reviews to see what people have said about them. if any of them seems to get bad reviews then pick the other.
