Your 26" Philips television (720p) certainly is High Definition according to the ATSC HD definition. I assume as the one I am looking at is 1366x768, it will scale up 1280x720 HD pictures to fit, or I can opt for black bars top/bottom if I don't want the picture distorted? Is that what TV's with native resolutions that don't match the HD spec exactly do? Cheers, D. 1366x768 is a common resolution for LCD and 50" and up plasmas. It is HD. All HD TVs will scale the input signal - 480i SD (analog or digital source), 720p, 1080i to the resolution of the display screen. The scaler is part of what you are paying for when you buy an HD TV or monitor. Some HD TVs have a 1:1 pixel mapping mode for PC input via a VGA or DVI port bypassing the scaler for those who want that feature. At under 50", the benefits of a true 1920x1080 resolution display for anyone sitting at a typical TV viewing distance of 8 feet or more is very limited. The human eye simply does not have the angular resolution to see much of a difference. At a 26" 16:9 screen size, you could get a ED (854x480) display and not see a difference more than 6 feet away. Keep in mind that a 26" 16:9 widescreen is less than 13" high. The screen height is close to the same as a 21" 4:3 set. For 16:9 TVs, screen height is 0.49 * the diagonal; for 4:3 sets, it is 0.6 * the diagonal. Hence to maintain the same screen height of a 4:3 TV, you should buy a widescreen TV with at least 1.2 * the diagonal of the 4:3 set you are replacing. So a replacement for a old 27" 4:3 CRT TV should be at least a 32" widescreen. Alan F |

I assumed it was like when I replaced my 17" CRT PC monitor (viewing area 14.5") with a 17" TFT (17" viewing area) - I gained something substantial even though the figures suggest I didn't. Will a 26" LCD TV measure up roughly the same as a 28" CRT? D. |

It's overpriced. the response time blows.
8ms - is that bad? It's about the same as my PC TFT, which seems quick enough when I'm watching DVD's. For under $250 US get a CRT that blows it away. I want to plug the PC into it and use it as a PC as well as a TV, for a bit of armchair internet surfing - surely no CRT can cope with the definition required in looking at text, so I assume LCD is the only way to go?

After looking at many HDTV's, I decided to get the Philips 26" you mentioned. I'm very happy with it....it does everything I want. It fits perfectly in our den/computer room. I got my TV at Wal-Mart. Their price is $824 (USD) Thanks for that - I'm in the UK, hence probably why the price is a bit higher - but it looks like it does all I want, especially 2x HDMI ports and integrated digital receiver. I will be getting it from Costco. D. In your previous post you said this set is HD Ready and here you say it has an integrated digital receiver; so my guess is that the integrated digital receiver is NOT an HD receiver. That means that if you want to watch an HD channel you will need a set top box. |

Will a 26" LCD TV measure up roughly the same as a 28" CRT? D. A widescreen 28" CRT? That must be a massive item. Since TVs have always been measured by their actual display area (with a small margin of error for CRTs because you can shrink or expand the display area), this is not the same as computer monitors. At one time, they did use the actual full dimensions of the CRT tube for the CRT display size including the black margins around the edges that could not be used. This won't be the case to any significant extent with the 28" widescreen CRT if it was sold as a TV (which falls under FCC regulations). Keep in the mind, that the 26" LCD may be rounded off from the actual dimensions. It may be 25.7" or 26.2" diagonally and is rounded off to 26". Have to look at the detailed specs to find out. I expect the 26" LCD will have a smaller true screen size than the 28" widescreen CRT. If you are planning to use it part time as a desktop PC monitor, you need to check the specs very carefully to see if the 26" LCD will provide for PC input. Also at a sitting distance of 18 to 24 inches, the 1366x768 resolution will be limited for PC use. It can work, but TVs and computer monitors have different needs. Alan F |

They may find the four HD channels appear in the EPG but they will be unable to watch anything since the hardware inside the receivers is exclusively designed for SD MPEG2. If true this may be because the receiver or integrated HDTV was made with HD reception in mind. DVB-T is capable of receiving HD. It is being used in Australia. The tests use MPEG4 AVC, the MPEG2 decoders inside set-top boxes sold in Europe won't receive it, nor would an Australian HD receiver. Even a French MPEG4 HD STB won't tune into the UK HD transmissions. Some DVB-T receivers being sold in the UK are upgradeable OTA. Yes, but the decoding of the video stream is done with hardware, not software, therefore cannot be upgraded over the air. You also obviously can't receive an OTA upgrade which will magically add an HD output (like component or HDMI). Pretty much all set-top boxes sold in the UK only have a composite and RGB SD output, no component and no HDMI. Likewise the TV is unlikely to have been designed to support anything higher than 576i as far as the internal digital tuner is concerned. A high-end PC struggles to decode the MPEG4 AVC HD streams live, the basic silicon inside a digital receiver doesn't stand a chance of being able to do it with software. Many can be upgraded to receive MPEG4 and receive 8K COFDM. How many I don't know. Maybe most. Check with your vendor or ask on I wouldn't say many. It may be possible to upgrade some with a suitable slot using something like this; http://www.neotion.com/products/modules.php however it still won't get around the fundamental issue of the hardware only being designed to output an SD 576i signal. http://www.idtv.co.uk/ http://www.digitalspy.co.uk/forums/f...play.php?f=158 Bob Miller |

There are many of us in this newsgroup who would like to thank you for
setting Bob straight. For someone from the UK disputing Bob's claims this post was long overdue and enjoyed by all (except BM). Thanks mattk! Drewdawg mattk wrote: "Bob Miller" wrote in message ...

Not true. They may find the four HD channels appear in the EPG but they will be unable to watch anything since the hardware inside the receivers is exclusively designed for SD MPEG2. I said people report "being able to receive this HD broadcast with Freeview receivers". Didn't mean to imply ALL Freeview receivers. USB Freeview receivers are made that work in other countries. There are now HDTV sets that work in the UK, the US and other countries. If true this may be because the receiver or integrated HDTV was made with HD reception in mind. DVB-T is capable of receiving HD. It is being used in Australia. The tests use MPEG4 AVC, the MPEG2 decoders inside set-top boxes sold in Europe won't receive it, nor would an Australian HD receiver. Even a French MPEG4 HD STB won't tune into the UK HD transmissions. PCI cards and USB based receivers can take advantage to the computer they are attached to for MPEG4. Some DVB-T receivers being sold in the UK are upgradeable OTA. Yes, but the decoding of the video stream is done with hardware, not software, therefore cannot be upgraded over the air. Again not those attached to computers of any kind. You also obviously can't receive an OTA upgrade which will magically add an HD output (like component or HDMI). Pretty much all set-top boxes sold in the UK only have a composite and RGB SD output, no component and no HDMI. Likewise the TV is unlikely to have been designed to support anything higher than 576i as far as the internal digital tuner is concerned. A high-end PC struggles to decode the MPEG4 AVC HD streams live, the basic silicon inside a digital receiver doesn't stand a chance of being able to do it with software. There are lots of high end PCs that can handle MPEG4. Many can be upgraded to receive MPEG4 and receive 8K COFDM. How many I don't know. Maybe most. Check with your vendor or ask on I wouldn't say many. It may be possible to upgrade some with a suitable slot using something like this; http://www.neotion.com/products/modules.php however it still won't get around the fundamental issue of the hardware only being designed to output an SD 576i signal. Don't believe all Freeview STBs are limited to SD or 576i. Makes sense to me that an HDTV that works in the UK with Freeview and works in OZ with MPEG2 and 8K would also work with MPEG4 and the test in the UK. The folks designing such a set should be smart enough to future proof it at least that much. You may be right but I did hear of some receiving the HD test signals. Thought nothing of the reception and decode problems. I was amazed that they were not encrypted but even then someone knows how it is being done and others can hack it I am sure. I am sure some are doing it with PCI cards and USB devices and probably even STBs. Didn't mean to suggest that anyone could or that many were receiving the HD test with any off the shelf Freeview receiver. "People report" could be a few hackers.
