I was using these forums for the last few weeks to do research on the new TV I was planning on purchasing. I ended up settling on an LN52A750 so I figured I would post my experiences on here for anyone interested. I would like to start by saying I am absolutely in LOVE with this screen. While I was hunting for the screen that was right for me, the Samsungs just screamed out at me for multiple reasons. I was originally planning on buying the 650, but after seeing them both, playing with them both, and reading up on them both, I decided the extra 200 dollars or so I would pay would be worth it (I talked the salesman down a bit ). I picked the TV up last Friday, and have since have pretty much ran it thorugh every conceivable configuration and settings. I have attached my macbook to it, PS3, Xbox360, wii, DVD player, Cable television, OTA HD Digital TV broadcasts with an antenna. I have played SD (cable obviously) 720p/i 1080p/i content using component, vga, hdmi, coaxial, RCA, and s-video. I have played around with the w.link pro. I have also tweaked the screen settings to all hell, played with AMP alot (I really like what it does to the video output). I have not played with DNLA yet but I will be shortly, I just have not had the time. As far as amp is concerned, I read alot about how there were some firmware updates that changed the strength of the AMP for the 650s. I would like to mention that the AMP feature has multiple strength settings in the menu in case you were not aware (Off, low, medium, high). The AMP works GREAT for playing games, such as GTAIV, that do not run at a great frame rate. I have noticed it can make TV and DVDs look a bit unnatural, but after watching it for a while, I stop noticing until I turn it off, at which point I turn it back on because after getting used to it, I dont want to stop using it. I really like the chassis as well. The controls for the TV are actually behind the front glass, and illuminated touch sensitive. It is very slick. Over all, I absolutely LOVE this TV and could not imagine having got anything else. I am very pleased with my purchase.
If anyone has any questions or wants pictures, etc., please let me know. I will keep an eye on this thread for a bit.
P.S. I have noticed the HALO EFFECT but in all honesty could not care less. If anything It's kind of neat looking.
