2. LG Electronics 50PG30 50-inch Plasma:

It is a 50” Plasma HDTV with stylish design yet not so impressive image quality, and is inexpensive for its screen size, too. Sometimes it shows blurry moving images, vagueness and flat figures. The set up wizard and its optimizing options makes setup process quite easy. Menu icons are rationally placed, and they do not obstruct the picture because of being transparent. The quick menu option gives direct and easy access to frequent options like picture mode and sound mode. Also, the pop up selections put those sources on top of the priority list that are sending signals to the TV, when the button is pressed.

LG Electronics 50PG30 50-inch Plasma TV doesn’t have a backlit programmable remote; neither does it possess USB or SD card multimedia capabilities. Also, there is no picture in picture option.

• Very economical for its size
• Nice on screen menu

Limitations:

• No USB or SD card option

This set is master at showing details of images. Artifacts, washed out colors, pixilation, and excess brightness are common. Sound is not great; do not anticipate much about it. Remote is not designed logically, and the tiny buttons are difficult to use. Remote is backlit, but not all the buttons glow when light is switched on. When the input button is pressed, all the available inputs get listed as “input 1” and “input 2” style whether they are attached or not. USB, SD card and Ethernet supported multimedia option cannot be found.

Product’s Unique Selling Points:

• Well placed side mounted connectors

Limitations:

• Poorly designed menus
• Useless backlighting of remote

5. Vizio VF550XVT:

Pretty inexpensive, this HDTV has a finely backlit remote that is also programmable. It shows heavy pixilation and color accuracy problem. Sound system suffers weak bass, and audio quality is not applaud-able. The on screen menu is quite unhelpful. Picture in picture and backlit remote are its good points.
A poor performer, but it is cheap, too.

Product’s Unique Selling Points:

Nicely backlit remote
Picture in picture
Inexpensive

Limitations:

• Poor performance
• Low quality audio

The list ends here. You, now, have enough and adequate knowledge about large screen HDTVs, and can make a decision that which is the one for you.
