Q I’d like to know if it would be a waste to use a power amplifier connected to the preamp outputs of an AV receiver with the same rated power. The AV receiver I have in mind is the Denon AVR-3313CI.—Morris Barber / via e-mail

Q Both my TV and Marantz AV8801 surround processor provide video adjustments. If I tweak the settings for both, will they conflict with each other? Also, if the Marantz does a good job handling video processing, will there be any advantage to using a high-end player like the Oppo BDP-93 instead of a PS3 for Blu-ray playback?—Michael McGehee / Macon, GA

There’s no doubt that Smart TVs have been getting smarter. While the earliest Smart TVs were limited to streaming movies and basic Web browsing, today’s models may encompass voice or gesture commands, the ability to “throw” your favorite photos to the screen from your smartphone, facial recognition for customized user menus, or even the ability to recommend shows based on your past viewing.

Q I recently updated my old receiver with a Pioneer VSX-1123-K. The difference in picture and sound quality is fantastic. I had also planned to update my old Blu-ray player with an Oppo, which I hear has superior picture quality due to its use of a Marvell Qdeo video processing chip. I’ve heard that the VSX-1123-K also uses the same processor. Does that mean I wouldn't see a difference in picture quality if I upgraded to the Oppo? —Al Baran / Stratford, CT

Q Sony has produced some Blu-ray discs that are mastered at 4K resolution and have an expanded color gamut called xvYCC. Is this the same thing as Deep Color or the DCI color space on Panasonic Plasma TVs?  Also, do I need to calibrate my TV for xvYCC, Deep Color, or DCI instead of the Rec. 709 color space to see expanded color with these discs?— William Lee via email

Joe Kane is a name that should be familiar to most, if not all, videophiles. The man is almost single-handedly responsible for getting manufacturers to put advanced picture settings in TVs that let calibrators make grayscale and CMS adjustments so your set stands half a chance of displaying accurate color. Without Joe’s vigilant advocacy, TV picture quality now might very well still suck as badly as it did back in 1989.

The two biggest TV trends happening at CES are higher-than-HDTV resolution and ultra-large screens. According to Sanus, both trends mean that heavier-duty-than-normal mounts will be required to deal with the increased weight of the larger, higher-rez screens.

Smart TV tends to take a backseat to other TV developments at CES, but LG’s demo of its new WebOS Smart TV interface in some ways proved almost as compelling as the 77-inch, 4K-rez OLED the company had on display.

When high-definition TVs first showed up in the late 1990s, the arrival of the new sets was preceded by the establishment of a digital high-definition TV broadcast format. In other words, the horse was leading the cart. With UHDTV, however, there isn’t a new higher-rez broadcast format to go with the new displays. What gives?
