So, I had S27A850D in order and now I got message they don't manufacture it anymore and S27A850T is the replacing model, Should I get the 850T ? What is difference between D and T? They're willing to give me discount for the 850T (drop it to same price as D) as I had it on order for several weeks. Any information would be helpful, kinda don't wanna buy cat in a bag. Thanks
