My 2 cents...
My pani P50g25 died on me the other day. I read the reviews for the 55LM7600 on Amazon and Best Buy then went to Best buy to check it out.
I was caught up between the new pani P50GT50 and the 7600. I went with the LG because of the WOW factor and the 3d.
So here's my review so far... The LG is a nice TV but isn't perfect.
Out of the box, the TV was ok. I went online, found a bunch of calibration settings and tried at least 4 of them so far. Adjusting the settings makes a big difference from out of the box.
The TV picture is good but can't compare to my 2yr old Pani. It seems that with every show I watch, I have to make an adjustment to some setting. As you can imagine, this gets annoying. The display is either too warm or too cold and even while watching the same show I found that some scenes were too warm and other scenes were too cool. I can't seem to find a happy medium here.
As far as the bleeding is concerned. There's a slight bleed coming from the top and bottom but it's not terrible.
My son plays both XBox and Playstation. He's been playing this batman game and it looks pretty good as far as I can see.
On a positive note, the sound is better on this TV than the Pani but sound can be fixed with a soundbar. The remote IMHO is pretty good. The apps on the TV are fair. They run a bit slow. Using Youtube through the browser is much quicker than using the actual Youtube app provided by the TV. Also, I was able to plug in my HP Bluetooth keyboard to the TV and search the web with ease. The only issue is going to flash pages. Seems the latest version of flash is not installed and I haven't put much time into figuring out how to update it.
I purchased the TV at Bestbuy. It was on sale for 1799.00. The sales guy went to the web and found the lowest price 1389.00 which was pretty good.
I'm considering a return and picking up the Pani P50GT50. I thought the colors were much better on the Pani and I didn't have to change the settings with every single show I watched. I think for now I can live without the greatest 3d functionality. I know plasma's in general have their own issues but I was very happy with mine until recently.
All comments welcomed. I hope this helps with your purchase.
