So now that my return is over, I'd like to share my experience so hopefully it won't get repeated. I originally bought a glossy panel from green-sum on 8/22 and it arrived at my door 8/26. The panel worked ok, had a little BLB and a dead pixel. It had a defect in the top middle where there was a dark spot(clouding I suppose). The panel was also a tempered glass model and not a glossy one.
After two days, I woke up to see my glass fall off it's mount
Of course at this point I requested a return. After a day, the seller insisted that the monitor was damaged during shipment and wished to have UPS pick the package up to inspect it. There was no visible damage on the package, so I think she just filed a claim to see what happens. Unfortunately, UPS never contacted me, so I had to contact them and initiate it myself. The package was finally picked up on 9/5(I requested the RMA on 8/28). Note that I've been in contact with the seller this whole time, but she only responds once a day - it's very frustrating to communicate with someone only once a day. I had to make my messages count and a few times I never got questions answered.
I'm assuming UPS inspected it quickly because the package was immediately returned to the sender. By 9/7 it was in Korean customs. It literally sat in customs until 9/11 until green-sum provided her phone number to clear it. Then it was put on hold for a customs invoice to clear duty relief! That lasted until 9/16! On 9/17 it was finally delivered back to green-sum. But wait, there's more...
The seller contacted me on 9/18 to let me know that my replacement was going to be shipped...after Korean Thanksgiving(Nooo!). Not the end of the world I guess. I already waited so long, what's a few more days. Then Monday rolls around(this week). Instead of getting a tracking number like I expected, I get an email saying they are out of stock of glossy monitors. Apparently, everyone is out of glossy monitors but they still show them in stock and ship tempered glass in it's place. She didn't think I would notice the first time which is why it wasn't mentioned until now. My choices were matte or tempered glass. I chose tempered glass again. My thoughts were, if the glass fell off again or annoyed me, I would take it off like others have. Amazingly enough, it was shipped the 25th and arrived at my doorstep early this afternoon.
Opened it and am using it now. No BLB! Wow! At first I thought I had 2 dead pixels but I determined it was dust specks between the glass and screen. Best way to tell this is to put the "pixel" inside a tiny circle in paint. Then change viewing angles left to right. If the pixel moves outside the circle, it's dust. So no dead pixels either. OC'ed it to 120Hz right away(now using the cable from Amazon that someone mentioned a few pages back). My only complaint is there is some weird light clouding that can be seen at bootup with a black screen. After all this, I seriously don't care, as it can only be seen with a black screen.
In hindsight, if I knew this was going to be so painfully long beforehand, I would have fixed it myself. My glass could have easily been removed and that dark spot probably could have been fixed but cleaning between the screen layers(as someone else previously showed with an iMac video). I'm glad things eventually worked out but that was a long process. Most of the issues stem from the fact I could only communicate with the seller once a day. I only have a week left on my eBay buyer protection and I've only gotten to use this monitor <4 days total. Hope this helps someone in the future.
