The Sony KDL-40W5500 is a good example of what you should be looking for if you are planning to upgrade your home cinema system. Rather than spending a small amount of money in getting something that is half-hearted attempt to playing high definition content, it is worth spending a bit more money by getting a highly decent quality product.

Even if you are upgrading from another large LCD television, you will probably notice the difference and with its high specification, the Sony KDL-40W5500 manages to successfully upscale older content to look much higher quality, including the current television broadcasts.

Panasonic also provides a thirty seven inch television set in the G-series product line, one that is typically considered as the high end offering from Panasonic.

The black panel screen weighs slightly less than 30 lb.. And can swivel up to 15 inches. Despite its recent introduction, the Panasonic Viera TX-L32G10 TV has already received awards for “excellent screen uniformity” and “good all-around picture” quality. Among its noteworthy enhancements are a superb moving picture quality, wide viewing angle, and advanced networking capabilities.

The Panasonic Viera TX-L32G10 sports a respectable 1920 x 1080 progressive scan resolution. In addition to a 16:9 aspect ratio, this LCD screen possesses a 50,000:1 dynamic contrast ratio. This ratio can be a bit misleading given that dynamic contrast ratios are not as pertinent as native contrast ratios. The reason for this is that dynamic contrast ratio measurements are conducted using extreme back lighting scenarios whereas native contrast ratio measurements sustain a steady back light environment.

One of the main selling points of the Panasonic TX-L32G10 is the picture quality integrity. This is maintained by Panasonic’s Intelligent Frame Creation system. This television set has a 100-Hz sub field drive for rapid frame processing which is double the 50-Hz video signal input for eliminating ghost images and streaking. Given that the L32G10 is an LCD, viewing angle integrity is important, especially for the smaller televisions. The L32G10 has a 178 degree viewing angle, greater than its predecessors, and allowing for steep angle viewing.

A strongly marketed functionality of the TX-L32G10, is the Freesat tuner which allows the flat panel high definition television to intercept free HD broadcasts over the air. Aside from free satellite content, the flat panel LCD is also CATV compatible and capable of receiving FM radio signals.

Given the size and portability of this unit, it would be ideal for gaming. Although the resolution and picture quality will be component dependent, the TX-L32G10 is compatible with the popular consoles. The flat panel screen also has HDMI ports for additional components, such as Blue-ray players. The thirty two inch size also makes the television set popular for use an additional computer screen. The VGA and SVGA ports allow for easy connection to laptops and desktops.

Another unique feature in this Panasonic Viera TX-L32G10 television is the VIERA Link which allows for easy picture viewing directly on the monitor. The panel has a convenient SD memory card slot. Furthermore, the VIERA Link has a specific setting for the new LUMIX camera which can be linked directly to the screen through the HDMI port.

The Panasonic TX-L37S10 is what Panasonic coins as an entry-level Full HD LCD - this means it’s affordable and consistent with what is expected of it - but with no added bells or whistles.

The design isn’t anything special. Panasonic has not innovated but rather stuck to the now conventional sleek black look that most of its brothers have.

Looking at the back of the TV, we get a pleasant surprise by finding, in addition to the usual sockets, 3 HDMI input slots and an SD card slot. These HDMI slots are great in today’s high-definition obsessed world. Even if you don’t own a Blu-ray player, high-def digital camera, or games console, you may do soon, so its good to have the option for the future.

If you don’t own an HD-compatible camera, you have the option of using the SD socket to pop in a memory card and bore your friends and family to death with photos from your recent vacation. To make their experience slightly less painful, you can choose from various types of music and display effects whilst viewing.

The lower price tag does not mean that Panasonic has ripped out some of their brand-name goodies. One major piece of technology included is their Viera-standard IPS Alpha control panel, meaning:

Even if you are sitting at a tight angle to the television the picture is still crisp and sharp, without paling of the image. This is ideal if your sofa is not facing the screen, or you have several people round to watch the game.

A great contrast ratio is achieved through improved backlight technology and fully automated color management. The ratio claimed is 50, 000:1, which they say is achieved through active gamma-correction which constantly and almost instantly corrects contrast ratios based on analysis of the image on the screen at the present moment.

Images in motion are stable, and incredibly sharp. Motion blur and haloing is almost nonexistent, even when displaying today’s computer-generated fast action superhero movies.

One of the weaker points of the television is the Eco Mode, which reduces power consumption. This produces a rather dark picture so if you do opt for it, you will need to twiddle the contrast and brightness settings.

One area in which the TX-L37S10 really does excel is the hardwired freeview receiver. Panasonic are great at producing quality, noiseless upscaled images from normal definition signals and this is truly seen here. The same applies for DVD playback.

The television manufacturers state that they use their pioneering V-Audio surround sound. This is meant to alter the sound to accommodate the size of your room using sound reflection sensors on the TV. That said, the speakers are somewhat weak.

The TV is a real Full HD machine - and here it also shows its mettle. Blu-ray high-def signals are transformed wonderfully to the screen, with bright, vivid colors and crisp, sharp edges. Both CGI films and filmed movies with bright colors show strong and realistic coloring.

So, in summary, the Panasonic TX-L37S10 is a great all-rounder. For Full HD images at great contrast, with built-in Freeview, at a price that is affordable, you can’t really go wrong.
