Thanks for the question! I would be happy to help you out with this. Most Samsung TVs offer these aspect ratios: 16:9, 4:3, Zoom, Fit to Screen, and Wide Fit. In order to change the aspect ratio (screen size), you will want to head into the TV's menu, then to the picture sub-menu. Once there, head into the "Picture Options" option. Within that option, you will see the "Size" adjustment. Clicking into that will allow you to change the picture size of the screen. Please note: some of these options may be grayed out depending on the connection type you are using.

Thanks for the question. As a matter of fact, the method you mentioned is one of 2 different ways you can connect your TV to the receiver. Another way, and probably the easiest way, is to keep all of your devices connected to the TV, then run either an RCA red/white cable or optical cable from the rear of the TV (where the audio outputs are located) to the receiver. This will allow your devices to be viewed from your TV and have the audio sent to the receiver with minimal hook ups.

Thanks for the question. Although a universal remote should work just fine with the LN40B530, I would suggest that you review the manual for the remotes to make sure that Samsung TV codes are available to be inputted. Also, check the remote manufacturer's online site for updates on codes. Due to some manufacturers using different codes for their IR remotes, Samsung does not have access to the universal codes for the remotes.

A common question among consumers is how Plasma Technology differs from LCD Technology.

Both provide an excellent HD picture, offer stunning arrays of colors, and of course, Samsung’s exclusive technologies which allow you to get the most out of either panel.

LCD traditionally uses a CCFL (Cold Cathode Fluorescent Lamp) backlighting system that runs across the rear internal portion of the unit to illuminate the LCD panel from behind (however, the Samsung LED Televisions use LEDs for its backlighting unit). The lamp life is estimated up to 100 thousand hours, enjoys a tremendous following of enthusiasts, and translates into years of enjoyment of an affirmed, reliable and trusted technology.

Plasma Televisions operate using a combination of gas and glass to illuminate the individual pixels, or light sections, within the screen. The life of a plasma panel is up to 100 thousand hours, allows an expanded viewing angle over LCD, and has a response time as fast as .001ms. Some models are also capable of 3-D video. All of the Samsung Plasma units have a feature called Screen Burn Protection, which helps reduce the effects of static images and provide a quality image for the life of the panel.

Conventional LCD Televisions offer a great picture without image-retention and smooth image motion using the Auto Motion Plus processing. Plasma Televisions offer faster response times, future abilities for 3-D experiences, as well as appeals to customers replacing a tube television with a glass screen they are familiar and comfortable with. And, due to advances in technology, both plasma and LCD screens can work well even in the brightest rooms.
