4K for the PS4? Who cares?

Rumors abound that the next-generation PlayStation will be able to output 4K resolution.

Normally, I find rumors about as useful and interesting as other people's gas, but this one stinks on a different level.

Allow me to confound with reasons why I think 4K output with the PS4 is simultaneously likely, and pretty much irrelevant.… Read more

Are letterboxed movies really 1080p?

CNET Reader Doug Hagemeister asks:

Hello! I was watching a movie on Blu-ray the other day filmed in the 21:9 aspect ratio and I realized that it technically wasn't "1080p" since about 1/4 of the screen was taken up by the horizontal black bars (called "letter boxing," correct?). Anyway, I was just wondering how many pixels were being used on the TV. Thank you!

Ah, letterboxing, how I love you.

To understand letterboxing, we have to talk about aspect ratio. HDTVs are 16x9, or 1.78:1. Slightly wider than they are tall, they're pleasantly rectangular. Old-fashioned tube TVs were 4x3, or 1.33:1, so closer to square. … Read more

Why 4K TVs are stupid (still)

Editors' Note: An updated article entitled Why Ultra HD 4K TVs are still stupid was published on January 28, 2013.

A few months ago, hot on the multitude of 4K TV announcements at CES, I wrote an article called "Why 4K TVs are stupid."

I was shocked, shocked to find so many angry, contrary opinions on the subject. I mean, this is the Internet. Surely everyone is cordial and like-minded.

The comment section was the usual bog of ad hominem, straw man, and plain nonsense arguments. But buried deep within the chaff were a few good questions worthy of rebuttal. So if you'll indulge...… Read more

What is the white line along the top of my screen? (Morrison's Mailbag)

CNET Reader R. Savoy asks:

I recently purchased a 60-inch plasma and used your recommended picture settings. Question: I have my picture settings set to Screen Fit instead of 16:9 and on some stations when they go from hi-def to 4:3 I get a white flickering line right above the top of the picture. This problem doesn't present itself on the 16:9 settings, please advise, thank you.

Good question. Annoying answer, sadly.… Read more

Rear projection vs. LCD vs. plasma

Rear-projection TVs used to be the only way to get the "big-screen" experience at home. With the advent, and diminishing price of, large flat-screen LCDs and plasmas, the RPTV has become something of an endangered species. In fact, only one company, Mitsubishi, still makes RPTVs.

Many people still enjoy their RPTV, and I've received several letters recently asking if it was time for them to upgrade.

Are RPTVs a viable alternative to flat panels? When should you upgrade your old RPTV? Let's break it down.… Read more

Why do my eyes hurt while watching TV?

CNET reader Jerry asks:

I recently bought a 40-inch LED LCD. I like it a lot, but over the past few months I've noticed my eyes hurt after watching the TV. Mostly it seems to happen at night. This can't be normal, right? Before I spend money on an eye doctor (I've never been), I figured I'd ask if there was something about the TV that was causing it. I never had this problem with my old TV.An interesting, and surprisingly common question.

How big a TV should I buy?

37? 42? 50? 65? 90? There's an HDTV size for every room and every budget.

But if you're not limited by a cabinet or entertainment center, how big of a TV can or should you get? … Read more

Can I use an 'indoor' TV outside?

CNET reader Jason asks:

We have a covered porch that's screaming for a television. I'm not worried about the "elements" as much as I am about the extreme heat and cold. Here in North Texas, we can see summer temps as high as 110 degrees and winter temps in the teens.

I know there are "weatherproof" televisions out there, but they are expensive. Is that my only route, or are there certain TVs that do better in the heat or cold of outside?

Good question.… Read more

Don't buy a jumbo LCD TV, buy a projector

With all the hype and hoopla about Sharp's 80-, and now 90-inch LCDs, I think it's important to point out that these are neither a good value, nor a good idea if your goal is a big TV for the home.

Yes, I'm talking about projection, and it's easier, cheaper, and better looking than a big LCD.… Read more

Active 3D vs. passive 3D: What's better?

CNET reader Taher asks:

I'm trying to decide between two 3D TVs: a Panasonic that's active 3D and LG that's passive 3D. LG has all these international certificates for the best 3D picture and claims it's full resolution, but you and others claim Passive 3D is half the resolution of a real 1080p. Is there is a way for me to really tell the difference between an active and a passive 3D?

There sure is.… Read more
