Sorry for lack of updates, I'm still waiting for UPS so there was nothing to update the thread with.
The seller is not willing to ship out another monitor until UPS initiates the pick up of the damaged one so that's the cause of the delay in the return process. I can't fault the seller for this policy but I sure do blame UPS for extensive delays. When UPS finally picked up the first damaged monitor, the seller shipped out the replacement within 2 hours of being notified that the first damaged monitor was picked up! Impressive, especially considering there is a 12 hour time zone difference.
Many sellers have discontinued selling the 40"+ variants due to high return rates. Ebay sellers I spoke to said that 1 out of 3 shipped monitors suffer major damage in transit. Two major causes of damage are drops from significant heights and boxes crushed on conveyor belts during transit, the smaller the box, the less likely it is to get crushed but with 55" screens...
These monitors have a solid aluminum frame, considering the force needed to bend the frame in the manor it got damaged on the second monitor, no amount of cardboard and Styrofoam would have saved it.
UPS charges exorbitant fees for additional protection. I've contacted a few sellers, they say that wooden crates tend to ensure safe arrival but admit to refusing to use this method since it eats into their margins to the point of killing any incentive to sell units like that.
Through this ordeal, I've communicated with the seller so frequently, I pretty much became friends with one of the seller employees.
These monitors also sell on newegg but there is no stock that's shipping out of the US, if you buy on newegg, it's the same transit out of Korea you have to endure, the only difference is you pay more via newegg.
@tential: Just order one. In case you get a damaged unit: Drink lots of liquids and make sure you stay hydrated. Take plenty of pictures, including closeups of packaging and styrofoam blocks and the UPS label, make sure the tracking number on the label is legible. Pack up the monitor and contact the seller. They'll initiate the return. Now you must patrol your phone, UPS will call you but from a number that cannot be called back.
Both the call and the pickup attempt are certain to occur at the most inconvenient time for you. If you miss their call, reaching the "damage exception group" is very difficult, think Ninja Gaiden level of difficult.
UPS loves sticking those "sorry we missed you" infonotice things on your door. If you have a job you must commute to, know that UPS will attempt pickup only if they assume you are not home. You must create the impression that you are not home to attract the UPS driver, create an elaborate trap to convince them you are absent, lie in wait until the very last second or your ambush will fail. If you commute to work every day, can you risk leaving the package at your door while you are gone? It is possible to extend the freesync range down to 33Hz.
@EJSLP: 4K/120 Hz is not yet possible. Monitors and TV's may use panels that are 60+Hz capable but actually skip frames beyond 60Hz. Existing 4K panels cannot go beyond 60Hz @4K, some monitors (not sure about TV's) can do 60Hz+ @1080p but not in native resolution.
@thilanliyan: The monitor is not available in the US.
