Review: Sony KDL-46Z5100


Sony's Z-Series TV offers a rich set of Internet goodies from Netflix to Yahoo Widgets and video podcasts.

Spectacular contrast ratio. Buttery-smooth 240-Hz refresh rate banishes judder and blur. Excellent universal remote with dedicated buttons for web content

Some noticeable artifacts when upconverting SD video. Streaming video limited to MPEG-2; no AAC support

Sony Bravia KDL-40Z5100


PCMag did not test the 40-inch Sony Bravia KDL-40Z5100. We did, however, test and review the 46-inch KDL-46Z5100 from the same series.

Excellent TV


I love this TV. It is the second Bravia LCD. My first one (a 32 inch) still works and I am moving it to another room. I love the interface for the TV. I also love the picture. I haven't tested many capabilities yet because I don't have an ethernet...

Great price/features/performance

Nit picky - I wish the splash screen didn't stay up so long on power up

Very Nice LCD TV, Good Value


This is a very nice LCD TV for the price. I had an opportunity to see the Samsung 8500 and Sony XBR8; they are definitely better, however they are 3 times more expensive. I will probably buy the XBR8 or one of the newer units this summer and retire...

Awesome TV!


Overall a fantastic television. The whole design of the thing is pleasing to the eye- even when it's turned off. Most of my friends say wow when they walk in the room and see this thing sitting in the corner. I know it's only 40 inches, but it still...

The picture is great. Blue-ray and 360 games look stunning. I didn't think I would get into all the extra features like Amazn streaming and such. Surprisingly, I've found those to be incredibly valuable. I've already purchased some HD programming from...

The Home interface (where you access all the special features) is set up like a PSP interface (probably like a PS3 too, but I don't have one to compare it to). It's good, but kind of clunky if you have a content category that has a lot of stuff in it ;...
