Actually looks like a really solid display. Thanks for the heads up! Do you have the + version (S-PVA vs S-IPS), and how does it compare to your HP?
It is S-PVA, and has slightly less saturated colors than the HP. The white balance is much more accurate OOTB, and I had to jump through hoops to get the HP to match. The reason I bring up the 3 year warranty is because I bought mine second hand on Craigslist. Very assuring especially when your panel fails, and a 5 minute call to Samsung gets you prepaid overnight and executive treatment (as happened in my case)
I dont know if the panel is shaky overall as I'm just one user, but the warranty is definitely a reason I would pick it over the HP.
