Will I Lose Pixels & Brightness When Zooming a Projected Image?
Al Griffin  |  Jan 27, 2021  |  0 comments
Q I ordered an Epson 5050UB LCD projector with 10 lens-shift memory settings and am looking for a projection screen. Information on one screen manufacturer’s website says you lose 25 percent (over 2,000,000 pixels) and up to and 25-30% of brightness when using a lens-shift memory setting to zoom images to fill a 2.40:1 “scope” screen…and when a projector blacks out pixels during this process, it absorbs the light energy, creating excess heat. Is this information accurate? Also, should I instead consider using an anamorphic lens with the projector? —Douglas Bien, via email

Q My new Denon A/V receiver has an eARC (enhanced Audio Return Channel) HDMI connection, and my TV has a regular HDMI ARC connection. Here’s my question: Will the Denon A/V receiver be able to decode both Dolby Atmos/Dolby True HD and DTS:X/DTS-HD Master Audio soundtracks that are routed to it from the TV’s HDMI ARC port, or do I need to connect sources such as an Ultra HD Blu-ray player and streaming box directly to the AVR to make that happen? —Andrew Last, via email

Q I have an older Pioneer VSX-820 receiver (circa 2010) and currently have my 4K Roku streaming stick plugged in to one of its HDMI inputs. I plan to upgrade to an Ultra HDTV (Vizio M65Q7-J01). If I continue to connect my Roku stick to the receiver, will it pass a 4K signal to the new TV? —Chris Murphy, via email

Will Running Video Through My A/V Receiver Degrade Picture Quality?
Al Griffin  |  Jun 26, 2014  |  0 comments
Q I own a Panasonic TC-P60ZT60 plasma TV. I also have a Pioneer SC-1323-K A/V receiver, the first I’ve owned with HDMI connections.

Here’s my question. Having dialed in the Panasonic’s internal settings to my satisfaction, am I losing picture quality by routing video sources through the receiver instead of connecting directly to the TV? Some receivers are praised based on the video processing chips they use, but do these actually do anything to improve picture quality when the source is HDMI? I’m using a Comcast cable box and a 1080P Roku to stream home movies from a PC located in another room. I also watch DVDs on rare occasion through a standard DVD player.—Rich Wegrzyn

Will the DVD Format Disappear?

Q Some of my friends argue that spending extra money on Blu-ray Discs is unreasonable since DVDs offer almost equal picture quality for less money. Worldwide, DVDs sell much better than Blu-rays, which many people still consider to be a format for videophiles. Do you think it’s possible that DVDs will ever disappear from the market? —Tomek Ciecwierz, Warsaw, Poland

Will Video Adjustments in My Surround Processor and TV Conflict?

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

Going Wireless
I have some very good wired speakers. How can I convert them to wireless in order to have more flexibility in placement? I do not want wires going throughout the room.

Wireless Whole-House Audio
Scott Wilkinson  |  Jun 01, 2011  |  1 comments
I need a recommendation for wireless speakers. My in-laws have four sets of speakers throughout the house controlled with a hard-wired switch box, but the system crackles and pops so badly that they have stopped listening to music. In lieu of crawling under the house to rewire, I want to know if wireless speakers are a viable option. I was hoping that something like a wireless Bose Cube speaker system existed? We don't mind spending a bit on an initial set or two.

WTF! Why Don’t All Streams Have Gapless Playback?

Q I just finished listening to the new Giles Martin remaster of The Beatles’ Abbey Road via a 24-bit/96kHz stream from Qobuz. For the first few tracks I felt like I was listening to the original album, but on a much better stereo system. Then the bad news came when I got to the medley on “side two” starting with “You Never Give Me Your Money.” Instead of a seamless flow between songs, I heard distinct gaps between the tracks. It really ruined the experience. Why can’t streams of album tracks that are supposed to segue do so without annoying, and at times jarring, gaps in the sound? There are lots of iconic recordings with the same issue. —Thomas E. Moore, Fairfax, VA

Don't Hold Your Breath
I was wondering if you could provide any info about streaming from a Media Center PC to an Xbox 360 acting as a Media Center Extender. I asked Xbox tech support if there are any plans to allow streaming from a Blu-ray drive on a PC to an Xbox 360. I could not get any kind of straight answer. Any info you could dig up would be greatly appreciated and possibly keep me from spending 400-500 bucks on a standalone player.

Blu-ray Shy
I would like your thoughts on Toshiba's XDE DVD players. As one who is hesitant to adopt Blu-ray fully, I have had a PS3 from the beginning, just no standalone player. I'm thinking of replacing my worn out upconverting DVD player with an XDE model, although Toshiba is quick to point out that it does not output or produce native HD content. Seeing how fiber-optic Internet speeds of 100Mbps are within reach, should one really look at Blu-ray with all the trappings that come with it?
