I begin this thread with this rather ominous warning in the Users
Guide for Samsung CRT HDTVs: http://downloadcenter.samsung.com/co...00Eng_0221.pdf +++ Important Warranty Information Regarding Television Format Viewing Standard screen format televisions (4:3, the aspect ratio of the screen width to height) are primarily designed to view standard format full-motion video. The images displayed on them should primarily be in the standard 4:3 ratio format and constantly moving. Displaying stationary graphics and images on screen, such as the dark top and bottom letterbox bars (wide screen pictures), should be limited to no more than 15% of the total television viewing per week. Wide screen format televisions (16:9, the aspect ratio of the screen width to height) are primarily designed to view wide screen format full-motion video. The images displayed on them should primarily be in the wide screen 16:9 ratio format, or expanded to fill the screen if your model offers this feature, and constantly moving. Displaying stationary graphics and images on screen, such as the dark sidebars on non-expanded standard format television video and programming, should be limited to no more than 15% of the total television viewing per week. Additionally, viewing other stationary images and text such as stock market reports, video game displays, station logos, web sites or computer graphics and patterns, should be limited as described above for all televisions. Displaying any stationary images that exceed the above guidelines can cause uneven aging of picture tubes(CRTs) that leave subtle, but permanent burned-in ghost images in the television picture. To avoid this, vary the programming and images, and primarily display full screen moving images, not stationary patterns or dark bars. On television models that offer picture sizing features, use these controls to view the different formats as a full screen picture. Be careful in the selection and duration of television formats used for viewing. Uneven CRT aging as a result of format selection and use, as well as other burned-in images, is not covered by your Samsung limited warranty. +++ To further complicate matters, Samsung provides for an automatic conversion to letterbox if you are watching SD WS as it sometimes does for commercials. It is my understanding that Full Screen (16:9 HD WS) is not suitable for SD WS, which is Letterbox viewing format - slightly smaller than Full Screen. If all you watch is HD TV channels then this warning is moot. But if like me you watch a lot of SD NTSC DVDR recordings (whether SD or HD source), then you either have to put the set in Full Screen, which allegedly distorts the image slightly, or run it in Letterbox for a clear picture which can end up damaging the CRT. Do LCD sets suffer from this apparent affliction? -- "Beer is proof that God loves us and wants us to be happy." --Benjamin Franklin |

If the problem is a acute as they seem to imply, then they should implement some kind of protection. This is just a CYA to cover those who leave the set on 24/7. The problem is they have sole discretion to honor the warranty. They say no more than 15% per week, which is totally absurd. Here's something I still am not clear about. If I use a conventional DVDR to record a program that I get from a standard NTSC broadcast OTA and it is in SD format, then the picture I display will be SD format. If I record an HD program from an ATSC broadcast OTA, will it show as WS format? If it does show as WS, then it would seem that you can get around Samsung's ominous warning by always playing an ATSC HD WS program. With a conventional DVDR you will have to buy an ATSC converter for OTA broadcasts or get a DVDR with an ATSC converter. What Samsung seems to be concerned about is using the SD or Letterbox viewing format. Neither is needed for true HD WS coming from an ATSC source. -- "Beer is proof that God loves us and wants us to be happy." --Benjamin Franklin |

Do LCD sets suffer from this apparent affliction? I've got both 4:3 and 16:9 HDTV monitors/TV's. I don't worry about this and haven't noticed any problems with either LCD or CRT sets. Normally though on the 4:3 sets, I zoom 16:9 shows to full screen cutting off the edges where there is normally nothng of any value anyway. Watching SD on the widescreen I never stretch it to widescreen and watch it with bars on the side. Haven't noticed any ill effects there either so far. I've had the set 6 months running about 6 hours per day. The 4:3 CRT is a 19" computer monitor about 7 years old. No burn in on it either. I dod keep the brightness and contrast low on it except when watching TV on it. -- Want the ultimate in free OTA SD/HDTV Recorder? http://mythtv.org http://mysettopbox.tv/knoppmyth.html Usenet alt.video.ptv.mythtv My server http://wesnewell.no-ip.com/cpu.php HD Tivo S3 compared http://wesnewell.no-ip.com/mythtivo.htm |

I reord on a PC, and I can output the display as 16:9, 16:9 zoom, 16:9 stretch (wider or taller), 4:3, 4:3 zoom, 4:3 stretch (wider or taller), fill mode which will fill the screen no mater what, and with no special attributes (as set by the transmission). On top of this, the TV also has modes. I leave the Tv set to aspect ratio and control display via the PC normally. Otherwise, one could get things all screwed up and counteract each other. So in the end, it all depends on what recorder and TV you have and how you have them set. If it does show as WS, then it would seem that you can get around Samsung's ominous warning by always playing an ATSC HD WS program. With a conventional DVDR you will have to buy an ATSC converter for OTA broadcasts or get a DVDR with an ATSC converter. I leave my 4:3 sets in fill mode as default. That way I always get a full screen picture no matter what the show. I can rotate through all modes with a single button push. -- Want the ultimate in free OTA SD/HDTV Recorder? http://mythtv.org http://mysettopbox.tv/knoppmyth.html Usenet alt.video.ptv.mythtv My server http://wesnewell.no-ip.com/cpu.php HD Tivo S3 compared http://wesnewell.no-ip.com/mythtivo.htm |

As far as our PC DVRs go. Aspect ratio and resolution stays as originally transmitted. GG |

In both machines, if you set the output of the DVD Recorder to "16:9", whatever you record will be look like the broadcast. 16:9 will playback as 16:9 and 4:3 will play back as 4:3. The kind of disk you use doesn't matter. I suspect you have the DVD-RAM playback set to 16:9 and the rest to 4:3. Check your setup. Dan (Woj...) |

What if the picture is 16:9 -- "Beer is proof that God loves us and wants us to be happy." --Benjamin Franklin As I've answered in other threads, with the Panasonic DVDRs, you can either capture both 16:9 and 4:3. If you set the output to 16:9, then the both will play back in their orginal shape. If you set output to 4:3, the 16:9 will get squeezed into a 4:3 frame and the 4:3 will look normal. One caveot: when we talk about the broadcast aspect ratio, we are talking about the carrier or envelope or frame, *not* necessarily the content. For example: If a high-def station broadcasts a 4:3 program, it will actually be broadcasting a 16:9 picture with black bars on the sides of the "program". The broadcast is not *really* 4:3, it's a 16:9 broadcast where only 4:3 is "interesting". If you record this program and play it back as 16:9, you'll get the 4:3 "interesting" part with the black side pillars. If you play this back as 4:3, you will *not* get a nice 4:3 filling your 4:3 screen. You will get a 4:3 picture with a sqeezed interesting part and black bars on the side. I think this whole part of the thread began with someone pointing out Samsungs warnings about burn-in on their 16:9 CRT HDTVs. Please remember, this is not new; this is the same burn-in warning that has *always* been valid for CRTs. Likewise, I believe that the concerns about Plasma burn-in are overblown as well; Plasma in someways can be viewed as an array of tiny phosphore tubes, just like the CRT. The burn-in effect is the same. If you didn't worry about burn-in on your CRT, why would you worry about it on your Plasma? In my personal reality, my 16:9 Plasma screen gets the heaviest everyday use. I find that my viewing is spread across 16:9, 4:3, 4:3 stretched to 16:9, and some odd-ball aspects that get zoomed to something between 4:3 and 16:9. It all seems to average out such that I haven't worried about burn-in or uneven wear during the 3 years I've had the set. And so far, the set still looks perfect. I would suspect that a CRT HDTV would be just the same. (Of course, my TV is only on for about 2-3 hours per day. I certainly don't leave it only all day/evening with a 4:3 image and a crawling ticker. If you do, you might want to consider LCD, projection LCD, or DLP. Or just stretching the screen. Some of the non-uniform stretch modes (like Panasonics) are really quite effective. Final note, I *have* seen burned-in LCD screens in my work labs, where the screens may have the same thing on them for months.) Dan (Woj...) |
