We aren't ready to upgrade to HD yet. Not even close. We never watch local
channels, even if we could get them with rabbit ears (which we can't). But when we DID live in an area with good local channel reception, we never watched nbc, cbs, abc or fox anyway. The main channels we watch are food (wife), tlc (wife), ngc, discovery, history, and several HBO channels. Of that list, I think one of them is available in HD. Nobody in our household has any interest at all in sports. So HD has nothing to offer us, yet. It doesn't make sense to upgrade a receiver and programming package just to watch Discovery in HD. ![]() However, our standard-def CRT TV broke this past weekend, and I wanted a flat panel of some kind to replace it. READ: large-ish, but something I could handle myself (not 200 pounds like the set that just broke!). Looking around, the only reasonable options I had were LCD HDTV televisions (or just monitors) in the 32-ish inch size range. Yeah, I found some EDTV sets, but they were about the same price as the HDTV sets, so what's the point? Not wanting to wait for a few days or longer to have a television delivered (could have got better deal online, but shipping would be slow or cost a fortune or both), I settled for what was easily available locally. That turned out to be a Westinghouse (Delta) 32" LCD HDTV on sale ($200 off) from Best Buy. Amazingly, this is the first time in several years that I've wanted to buy something at Best Buy, when they actually HAD what I wanted IN STOCK. Now, because this was a short-notice purchase, I didn't consider the other equipment in the entertainment center. But AFTER I got the HDTV home and started adjusting it (contrast/brightness/saturation/hue/backlight/color temp, etc.), I realized that my other equipment might need to be tweaked a bit to better match the new monitor. I discovered something VERY INTERESTING: Because our DirecTV receiver is fairly new (D11-300?), I believe, it has a new feature that even DirecTV support (the girl I talked to anyway) was not aware of. The newer DirecTV standard-def receivers are widescreen compatible! I found a menu in the DirecTV receiver that allowed me to change the output aspect ratio from 4:3 to 16:9. I wanted to know exactly what would happen if I did that. So I called, and the girl I talked to at DirecTV (after getting over the surprise that a D11 had that option) looked it up. This is what I was told. If you select 16:9, the DirecTV receiver puts back some of the video information that was clipped to make the output conform to 4:3 standard. I tried it, and sure enough . . . there is more video in the signal that is not displayed if 4:3 is selected. Bottom line, if you have the right DirecTV standard-def receiver, you can set the aspect ratio to 16:9, and then when you set your television/monitor to "fill" the screen, the people end up looking NORMAL!!! If you leave the DirecTV receiver at 4:3 aspect ratio and set your monitor to "fill" the screen, every person shown instantly gains about 100 pounds, as they are shown much WIDER than they should be. But with the DirecTV receiver at 16:9 ratio, the displayed picture is wider to begin with. So, when the TV/monitor stretches it to fill the screen, the resulting display is NORMAL looking, with no black bars!!! Unfortunately, the picture is still slightly distorted as I am running the monitor in a display resolution that is not "native". If anybody tells you that their HDTV monitor displays standard-def content better than any standard-def TV can, they are only kidding themselves. Standard-Def programming will never look quite right on a flat panel HDTV set. It doesn't look bad, but it's not as clear as it could be. But, I thought I'd post some good news for those who need a new TV set but aren't ready to go "all the way" with high-def yet. If you have the right DirecTV standard-def receiver, you can set it up to drive a HDTV TV/monitor *with no black bars*, and the image quality is more than acceptable, even if it's not quite as good as you'd get out of a standard-def TV/monitor. So don't be afraid to buy a HDTV TV/Monitor before you upgrade to an HDTV programming package. -Dave |

SD programming actually has an aspect ratio of 1.5 to 1, which is clipped, usually by the TV set, to 1.33 to 1. This is why, if you do make any video yourself, the viewfinder will show a "safe" area that is smaller than the available image. If you have SD programming that is not stretched and has no black bars, you must be clipping a small amount from the top and bottom of the picture. This may not be enough to be worrisome. Unfortunately, the picture is still slightly distorted as I am running the monitor in a display resolution that is not "native".

Standard-Def programming will never look quite right on a flat panel HDTV set. It doesn't look bad, but it's not as clear as it could be. Digital displays have one resolution that they look best at. It's up to conversion circuitry in the display to handle other resolutions. This ability varies greatly from one set to another. Also, an HD display will make the usual MPEG compression artifacts in the satellite signal more noticeable than they were. But, I thought I'd post some good news for those who need a new TV set but aren't ready to go "all the way" with high-def yet. I also use a SD Dish receiver with an HDTV (CRT). I get my high-def fix from local broadcasts; the DISH HD channels are not interesting to me. And with a good DVD player (like the Oppo 970), I'm happy with the overall situation, too. |

So are you seeing "more" detail within the same frame limits, or are you seeing "more" objects that are outside the 4x3 frame limit? What happens when a show would normally be letterboxed - does the receiver stretch it both ways to fill the screen? Or maybe your new display does that?

Standard-Def programming will never look quite right on a flat panel HDTV set. It doesn't look bad, but it's not as clear as it could be. My original Apple "Studio Display" does an exquisite job of upconverting SD signals to 1024X768. Sony's DRC "intelligent" pixel doubling also makes a clear improvement. It is possible. But you are right that most modern flat panels, even the ones that advertise a fancy brand of video processor chip, do a lousy job. Loren |

A 4x3 image in digital video is roughly 720x480, but the 720 horizontal pixels take up the same width as 640 square pixels would. Flat panels use square pixels, so the 720 to 640 conversion is required. So in one sense you are right, the pixel ratio is 1.5:1, but if you display that image directly on a square pixel panel, people will be overweight and wheels won't be round. Digital displays have one resolution that they look best at. It's up to conversion circuitry in the display to handle other resolutions. This ability varies greatly from one set to another. There's a candidate for the understatement award! Loren |

What happens when a show would normally be letterboxed - does the receiver stretch it both ways to fill the screen? Or maybe your new display does that? More objects are seen, if they happened to be in the overscan area when the video was produced. Well without getting too technical, it appears that some of the "overscan" area is recovered on both sides by selecting 16:9 format. The way I understand overscan, early 4:3 televisions were considered defective if ANY black areas were displayed. So all video had to be shot with a certain amount of "overscan" detail. Then the television itself trims the excess to give you a display that covers the entire viewable area of the screen (the picture is cropped, leaving the last inch or two not visible on the sides). As I understand it, the DirecTV receiver is altering the output to the television so that all video information is now in the "safe" area, and the overscan area (normally clipped by the TV) is nothing but black. The result is that you have a slightly higher resolution picture than you'd normally see in a 4:3 set, even though the source video was shot for 4:3. With the overscan visible on the sides, the video is closer to widescreen format. So when the TV takes what is now (virtual widescreen) and expands it out to fill the entire screen, there is less distortion (faces don't look five miles wide, for example, ha ha) Overall, I'm happier with the display quality than I thought I'd be. Widescreen DVDs are incredibly sharp, through the component inputs. Even the lowly SD DirecTV receiver looks good, through S-Video input. It looked better through a SD CRT monitor, but oh well . . . On a side note... I read some review somewhere stating that the monitor I chose has poor color accuracy. But I've checked gray level as well as levels of red, green and blue. Factory settings are totally ****ed up (just like all televisions, NO exceptions), but it can be adjusted to PERFECT color accuracy. In particular, the color decoder couldn't possibly be more accurate. With blue level (color level/saturation) and tint (hue) set correctly, neither red nor green are pushed at all. I should mention, I made the adjustments at the "warm"/orange-biased gray setting. There are sets out there with terrible color decoders (can't set blue correctly, or if you do, red and green are totally messed up), but the westinghouse/delta 32" LCD HDTV that Best Buy carries at the moment is NOT one of them. -Dave |

Then the television itself trims the excess to give you a display that covers the entire viewable area of the screen (the picture is cropped, leaving the last inch or two not visible on the sides). Very true. I remember back when TV was black-and-white, and the water pump starting up would both dim the lights and shrink the TV picture so much you could see the black edges. And see that an inch or more of picture was normally hidden. Often you could see the size change when the screen image got brighter or darker, as well. The power supplies were so variable, they couldn't keep the picture size stable. As I understand it, the DirecTV receiver is altering the output to the television so that all video information is now in the "safe" area, and the overscan area (normally clipped by the TV) is nothing but black. On my Apple display, even with S-video input, I see exactly all of the active video area, regardless of the source - DirecTV, VCR, or DVD. If I use its position controls to move the image one pixel in any direction, I see the blanking bars, data signals, VCR head switching, and other garbage just beyond the actual video. Often when the video has been converted from a foreign system, I see several pixels of artifacts along the edges. I thought all flat panels were like this, but my experience is limited to computer-capable displays. Could it be that flat-panel _television_ sets imitate overscanned TVs? CRT monitors sometimes had overscan/exact/underscan switches. It sounds like you are saying your DirecTV receiver has a switch that imitates a CRT monitor's overscan/underscan switch. Seems odd, but I guess it is possible. I certainly wouldn't expect it to be labeled "4:3 / 16:9" though! Loren |

I thought all flat panels were like this, but my experience is limited to computer-capable displays. Could it be that flat-panel _television_ sets imitate overscanned TVs? Good question. As I understand it, HD no longer uses overscan. That is, if you are producing 1080P, you are shooting 1920 (I think it's 1920) pixels of horizontal resolution and consumer level video equipment is displaying 1920 pixels of horizontal resolution, also, if it is capable of doing so and set up correctly. Most flat-panel television sets that people should consider buying at this point would be HD capable. EDTV is a real ******* of a technology, not really offering any advantage for SD content, yet incapable of displaying HD content. ![]() If there are any SD flat-panels (non-CRT-based) still on the market, I certainly couldn't find them, and I was looking for them. So my best guess is, flat panel TVs could imitate overscanned TVs, but don't need to, as that is so, so ....YESTERDAY. ![]() CRT monitors sometimes had overscan/exact/underscan switches. It sounds like you are saying your DirecTV receiver has a switch that imitates a CRT monitor's overscan/underscan switch. Seems odd, but I guess it is possible. I certainly wouldn't expect it to be labeled "4:3 / 16:9" though! Actually, it appears that that's EXACTLY what DirecTV has done with their more recent SD-capable receivers. And it makes perfect sense. I mean, how do you stretch out a 4:3 SD picture to make it look more normal on a 16:9 display? Reduce the overscan area to 0% on the sides!!! Now the picture is wider without actually being altered, at all. Now think about it from a user-friendly perspective. How do you label such a feature? "Turn overscan off" would be kind of cryptic. At least most consumers who own widescreen monitor/TVs would be familiar with 4:3 and 16:9. That's how I found that function. -Dave |

I'm in the market for a HDTV/LCD TV for use on Directv. I know the best
picture will be from a HD channel using a HD receiver. Can anyone answer the following two questions? (1) What will be the quality of non-HD channels when using a HD Directv receiver. Please compare to a standard CRT TV and receiver. (2) What will be the quality of any Directv channel using a standard receiver. Please compare to a standard CRT TV and receiver. Thanks |

I am currently using a Directv HD-DVR reciever playing through a Yamaha HTR reciever going to a Pioneer Elite 43 Plasma. In all honesty I try not to watch standard broadcast on this unit becuase I do not like the grey side bars. The picture is better than the unit in my master bedroomm, a Directv DVR with a 32" JVC CRT. I attribute this to the fact that the Pioneer Elite is state of the art and a high end unit. (2) What will be the quality of any Directv channel using a standard receiver. Please compare to a standard CRT TV and receiver. In all honesty the best to see how good the HD set is going to be that you are buying is to get a black and white DVD and have the salesman run it to the set you are interested in. If you are seeing black blacks and white whites you are going to love the set. Thanks |

In all honesty I try not to watch standard broadcast on this unit becuase I do not like the grey side bars. Does your DirecTV receiver not have an option to set your output aspect ratio to 16:9? Does your Pioneer Elite 43 Plasma not have an option to display/stretch an image full-screen? We've got a cheap 32" LCD HDTV running off a DirecTV standard-def receiver, and it looks pretty good! Fills whole screen, no gray bars, and people aren't stretched out like they are 2 yards wide, either. In other words, the picture looks very natural, with no viewing area wasted with black/gray filler. I find it tough to believe that you can't match that, with better equipment than we own. In all honesty the best to see how good the HD set is going to be that you are buying is to get a black and white DVD and have the salesman run it to the set you are interested in. If you are seeing black blacks and white whites you are going to love the set. Good in theory, but in practice? All televisions (NO exceptions) ship from the factory with really ****ed-up (to put it bluntly) picture quality settings. To make matters worse, probably .05% (or less) of retail workers have any clue at all that a television needs to be adjusted for optimum display quality. Even fewer know how to do it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! In particular, I will guarantee you that if you walk up to any random television set on retail display, there is a 99.99% (or better) chance that the brightness (black level) and contrast (white, in relation to black) are not only set wrong, but are nowhere NEAR being properly set. Typically, these are both set way too high from the factory, and never adjusted in a retail display (or worse, adjusted incorrectly). Therefore, blacks look light gray and whites will give you a migraine headache, instantly. Other problems are, most televisions leave the factory pushing red. The few that don't, will push green. This means the hue is off. Or typically, "flesh" tones will look pretty close to fire engine red, and nowhere near natural. Oh, and color level is often cranked up to near maximum also. Yeah, it's colorful. Too bad it looks so unnatural that way. Oh, and sharpness is often cranked up too high also. Too high meaning, anywhere above MINIMUM, because this control just adds distortion to the picture. Do I need to go on? Unfortunately, there is no good way to evaluate a television *for picture quality* on a retail floor. You can view any source you want on it (such as playing a black/white DVD), but you are seeing it at factory settings, which are always crap (ALWAYS!!!). The best you can do is pick a good name brand television, with a decent warranty, at what you feel is a fair price. Take it home, hook it up to a good DVD player, then find a good calibration disk such as digital video essentials and use that to set it up. If you are not happy with the picture quality after that, then you probably got a defective set. The good news is, even most of the cheapie television sets can be adjusted properly to offer very good picture quality. But even the high-end units will look like **** in a retail display setting. There's no way around that, as the manufacturers deliberately distort the picture to make the TV stand out on the sales floor. And you aren't going to spend several hours adjusting televisions on a retail floor (assuming you even know how to) so you can compare them, even if the retail store would allow you to do that (which of course they won't) -Dave |
