Asus has said they implemented special QA testing for the monitor which includes a dimmed room test for BLB. It's in the sweet spot for good fps gaming at ultra settings and looks awesome. If your not super critical on this monitors every tiny defect the monitor is one of the best out right now. Also I think most people that get this monitor may not even notice some of the issues or even care about some of that corner BLB as long as it's not that bad. Also the extra steps wouldn't help them sell the monitor by finding all the 'bad' ones and pulling them. The extra steps would cut into the profit. This would be understandable on some cheap, inexpensive budget monitor but not these. When you charge a price like that there should be extra steps involved in making sure these monitors are perfect. I really dont see where they get off on charging this much for these monitors. It seems like you have greater odds getting a bad panel than a good one. Absolutely ridiculous that these monitors have so many problems at this price tag. It seems damn near impossible to get a monitor thats flawless. I sent it in for repair, the replacement lcd had a bunch of dead pixels, i returned it again and they replaced it again. The first one developed a shadow streak in it. but basically for an extra $70 I can take this monitor back to them and get store credit for the price of the monitor up to two years from the date of purchase if there is a defect. I will be returning this to them at some point due to the defects. If you do go ahead with this monitor buy the extended warranty with a retailer (I have a 2 year with microcenter). The 3 I previously bought in January and returned were much worse.

only time you really notice is when there is a lot of white on screen. Mine also has a minor yellow tint issue.that basically you don't notice in any game. I bought mine back in may or june and it has some minor BLB on the right side and the usual in the bottom right corner.
