What Are The Best Settings for the GV47LF: Part II

Gallevia

Review site Secrets of Home Theater and High Fidelity just posted an excellent review of the GV47LF. The reviewer used Datacolor Colorfacts professional calibrating equipment to calibrate the television. So any owners of the GV47LF should head on over there and check out the entire the review for tips on getting the best picture from the television. I can say their suggesting settings improved my viewing experience.

Their suggested calibrated settings for the Vizio GV47LF:

  • Red: 133
  • Green: 126
  • Blue: 106

Their suggested advanced picture adjust settings for the GV47LF:

  • DNR: Off
  • Black Level Extender: On
  • White Peak Limiter: On
  • CTI: Off
  • Flesh Tone: On
  • Dynamic Backlight: AI
  • Adaptive Luma: On

I’ve been messing around with the backlighting settings on the television, and I’ve come to the conclusion that leaving the dynamic backlight setting on AI is the best way to go, whether you’re in a well-lit room or in a dark room. I’ve found that turning off dynamic backlighting in the advanced settings and adjusting the manual backlight to a low setting (less than 40) tends to make dark scenes murky, and can turn a bright sunny scene into an overcast day. If you use the above settings and dynamic backlight on AI, you’ll get the best compromise of black levels and vivid colors that this TV has to offer. You’ll also have more peace of mind by not having to fiddle with the television anymore, knowing the settings are from a professional calibration.

*Update* I’ve been using these settings for months now, and I am still totally happy with the picture in all lighting settings. I have not touched the settings nor plan on touching them any time in the future. Again, I recommend viewing your Vizio GV47LF in dimly lit rooms–avoid total darkness.

*Update II* Please note that picture settings for each input (broadcast TV, component, HDMI, etc) must be changed while in that mode–they do not replicate across all inputs. See my post on the subject.

*Update III* My GV47LF developerd a buzz sound (out of warranty, of course) that was produced from having the dynamic backlight set to AI. I have now changed it to On (this solves the buzzing problem while maintaining the bright, vivid picture the dynamic backlight provides). I have also messed around with the other picture settings and find that reducing the brightness to 47-50 and having contrast cranked up to 90-100 helps increase the black levels.

Upcoming Vizio GV52L and Sony KDS-50A3000

Vizio will be releasing a new 52-inch 1080p LCD soon, rumored to arrive sometime in August 2007. If you’re considering the GV47LF and can afford to throw a littlle more cash toward a television, it might be wise to hold off until you see some technical specs for the GV52L.

There are rumors on the AVSforum that the 52-inch will not be much of a step forward. Of particular note will be whether the 52-incher improves upon the GV47LF’s 800:1 contrast ratio (its base, or “typical,” ratio). If it does not, I would recommend going with the much cheaper 47, or even look elsewhere for a TV with deeper blacks.

Link to the AVS forum discussion: GV52L anticipation discussion.



Also arriving in late August to early September will be Sony’s 50-inch SXRD, the KDS-50A3000 for around $2499. It will have much deeper black levels than current Vizios, and all-in-all, looks like a pretty sweet television for the price. However, these kinds of televisions require a lamp replacement every 8,000 hours or so to the tune of $250. Probably not a television for the bargain hunter in you. (See picture of the SXRD below.)

My GV47LF Review: Worth Every Penny

GV47L Front Perspective

I made the plunge into the world of high definition television and purchased the GV47LF. Here is my review:

Intro

The GV47LF is a huge bargain and a great intro for first-time HDTV owners. It comes with an HDTV tuner built in and speakers (which are detachable). I am completely satisfied with the purchase. The TV works great and the overall picture quality is excellent–way beyond the standard definition experience. I am blown away by high-def television.  There were no bright or missing pixels and no mechanical problems out of the box whatsoever. This is the perfect, stress-free HDTV for any regular Joe who wants a huge 1080p HDTV but doesn’t want to go broke buying it.

In-depth Review

Now, let’s get into some details. The box the TV comes in is huge. Make sure you have a big SUV or a truck if you are purchasing it at Costco. The box was approx 4 x 3 x 1. Once unpacked and set on top of my TV stand, the TV looked much bigger than it did in the store. At first, I thought the TV was going to be too big, but now I am happy with the size, as the picture still looks great (unpixelated) at my ~8 feet viewing distance, even with 480i broadcasts.

Box

Big Box

I like how the TV looks. The black piano gloss gives the TV a finished “expensive” appearance, and the silver speakers give it weight and don’t look cheap or gaudy (although I do think the TV would look better without the speakers, which can be detached). I especially like the text in the center of the speakers that reads, “Gallevia. 1080 Progressive Liquid Crystal HDTV.” The font used for the text gives it a nice touch of stylish detail.

Vizio stylin’

The glowing “Vizio” in the center of the bottom bezel was handled well. It dims to a pale white after a few seconds of brightness when you turn the television on. When the television is off, the text glows orange. I probably would rather a more basic color, like dark blue, but that’s nitpicking. They are sticking with one of their branding colors, Vizio orange, which I completely understand. The glowing symbol is not gaudy or dominating in the least. The orange glow is barely visible in normal lighting; you wouldn’t notice without looking for it. It only stands out in a dark room.


The touch controls on the right of the bottom bezel briefly glow orange when you turn the TV on, then fade to no lighting. Some might wonder why the controls don’t have the same faint lighting of the Vizio text, but it makes sense to me because most people don’t want any distractions. The fact that the remote control that comes with TV has backlighting limits the need for the controls on the TV to glow. Just don’t lose the remote!

The touch controls are a very cool. The text and symbols are beneath the surface and do not interrupt the smoothness of the bezel, giving the TV clean lines with minimal visual distractions.

HD looks awesome on the television. I went from a 24-inch Insignia CRT to this screen, and my jaw dropped to the ground when I viewed HD in my living room for the first time. I had seen HD in stores and elsewhere before, but it’s a different thing all together when you get the TV home in your own environment. 720p signals at a vewing distance of 8 feet looks crisp and perfect, there is no pixelation, as would be expected. At the time of this review, I have only viewed 720p and 1080i signals on the television.

DVDs look crisp in 480p (with component cables) and do not appear pixelated at a viewing distance of 8 feet. The big weakness of the TV are black levels, but I want to point out that even though I will talk a lot about the black levels, I find them not to detract much form the overall viewing experience. However, it is noticeable, even to my amateur eye. Any time the screen fades to black or there is a scene that is almost entirely dark, the GV47LF shows black as ghostly black-grey, not black. There is also clouding, which is an unevenness to the blackness on the screen, displaying clouds or splotches of lighter shades. This was noticeable several times on Star Wars: Episode III: Revenge of the Sith. The weak black levels are most noticeable if you like to watch movies in completely dark rooms. It’s recommended you keep at least a low level of ambient light (turn on a single lamp with a dimmed setting), especially during movies with dark lighting or lots of space scenes. Check out my post of the best settings for the GV47LF or view CNET’s recommended dark room picture settings for help in improving the picture in to dim to dark lighting.

GV47LF Remote

It’s not remotely bad


Before I bought the television, I heard a lot of complaints about the remote. I think it’s fine. There is a lot of space between the buttons, so that basically makes up for the small size of the channel and volume buttons (see picture above). I find the commonly used buttons (channels and volume) easy to find without looking. It is also a “universal” control with programming for VCR, cable, and DVD players. Of course, if you have the cash, I’m sure there are plenty of better controllers for your money.

GV47LF Small Text

Time to see the eye doctor?

Another complaint is the small text of the Vizio’s menu. At eight feet, I have problems reading the text and have to approach the television to be able to read the settings. A small annoyance that seems like it should be easily fixed. Come on Vizio, just increase those font sizes!

There is an “info” button which allows you to see what signal is going into the television (1080i, 720p, etc), but the text is likewise hard to read.

Input

Vizio adds another touch of class by including a microfiber cloth to keep all the accidental smudges clean from your television. Whatever you do, don’t use Windex (you can damage your screen).

Keep your Vizio dust free

The detachable speakers deliver adequate sound. They are loud enough for everyday living rooms, even those complete with loud ambient noise (kids playing in the next room). For those who have their own sound system, the speakers are detachable via a screwdriver.

Conclusion:

There is very little to complain about with this television. High definition content is delivered beautifully with bright colors and no motion blurring. 480p DVD signals are also displayed crisp and clear. Clouding and black levels are the biggest con of the television, but are acceptable with a little tweaking. The screen is huge for those who sit 7-10 feet away from their TV. Anything above 50 inches would seem redundant and perhaps detrimental to the HD viewing experience. And you can’t beat the current $1,599 price at Costco with a 90 day return policy. This is the perfect television for 1080p hunters who are looking for a bargain.

Vizio GV47LF and the Vizio VP50HDTV at Costco

I just got back from my second trip to the Chicago Costco to check out the HDTVs. They had a fresh batch of the 50-inch Vizio plasmas (CNET review) sitting on the floor. I saw a guy at checkout with one on a pallet hauling it to his car, so at least one person must think it’s a better deal than the GV47LF. Not me though.

I got a second look at the GV47LF in action. This time they had a much better HDTV source running into the TV, and it looked really good. I would have bought it on the spot except I don’t have a car. I’m trying to get my buddy to help me haul it home. I asked at the help desk if Costco would deliver the TV to my apartment, and the young woman said local warehouses don’t deliver, but if I bought online and had it shipped, I’d get cheaper sales tax than Chicago’s 9%, and that would help make up the difference. So, I went home and did the math. Nope, no deal. Online is $150 in shipping and $109 in sales tax ($260 total) versus just $150 in sales tax at the store. Bad information.

GV47LF Price Drop

Costco has dropped the cost of the GV47LF by $100. It is now listed online for $1599. That price is making it awfully tempting for me to pick this up. I took the 32-inch Samsung out of the running. $1000 is too much to pay for that small of a television, now matter how good the TV is.

I added another con to my GV47LF pros/cons list. It is the non-defeatable overscan that causes horizontal stretching. What does that mean? A circle looks more like an oval. A poster on the AVSforum.com GV47LF thread said the picture is stretched 3%-5% of all non-1080p sources.

The Research: the Pros and Cons of the Vizio GV47LF (47 inch, ~$1700)

GV47LF

I went into my Costco yesterday (my first time in a Costco) in Chicago to check it out in person. They had the GV47LF set next to a $2200 Sharp Aqous, and I could really see a difference in the black levels. Another thing I noticed was pixelation during very fast motion, but I’m pretty sure it was just the HD source, not the television, since it was occuring on the Sharp too. I’m still thinking this purchase through, and to help me, I’m writing out my research and my thoughts. Here are the cons of the GF47LF (pros to come shortly). I culled these from various sources on the Internet and gathered them here for your information (note: sources are most notably the CNET review and postings form the GV47LF thread on AVS forum):

  1. As CNET pointed out in their review, the GV47LF’s black levels show lighter than most plasmas and some LCDs. In their tests, the letterbox bars appeared grayer than with the other HDTVs. This is not a problem limited to the GV47LF–it’s common in most LCDs. The black levels of LCD screens are slowly improving, but they still fall short of plasmas. However, there comes a point when black is as black as it’s going to get. Owners of LCDs say these black levels are only noticeable when comparing one HDTV to another. But once you get the screen home, you don’t notice the lightness of the blacks. For instance, you wouldn’t view a shot of space and think, “Wow, space is actually gray!”
  2. Some owners are experiencing audio synching problems, with the audio lagging behind the video. On AVSforum.com, they are debating whether it’s the TV or the HDTV source (cable TV + over-the-air broadcast).
  3. No dot-by-dot aspect ratio mode with 1080i sources.
  4. Nondefeatable overscan causes horizontal stretching. This means a circle will look more like an oval. An AVSforum.com poster claimed the GV47LF stretches the picture 3%-5% of all HDTV sources except for 1080p.
  5. The standard definition viewing experience will be a step down from normal (CRT) viewing.
  6. The remote is almost useless. You’ll have to purchase a new one.
  7. The menus on the television have an almost unreadable yellow text on gray background.
  8. Some owners have reported an annoying speaker buzz.

Now the Pros. Most are fairly obvious:

  1. The price, which is currently $1,599 (with Costco membership). What other flat screen is comparable? Look for yourself. There are 720p plasmas this size or bigger that are close in price, but do you want a 50-inch plasma with 720p?
  2. 1080p, which means it’s future proof. I’m not sold that cable  TV will get to 1080p within a couple years, but I do believe that other kinds of content will, and the ratio of cable TV you watch vs, say, computer (internet) or gaming content will slowly tip toward the latter.
  3. 47 inches. I live in 1 and a half bedroom apartment, and this size TV is perfect. Just on the verge of being too big, but still perfect.
  4. 2-year warranty from Costco. If you buy today and a pixel goes dead in May 2009, you’re covered.
  5. 90-day return policy. If you hate the TV, the only pain you’ll be feeling is having to haul it back to Costco.
  6. Removable speakers. I have need of the speakers, but one day I won’t. It’s very nice to have the option to remove them.
