You cant reset it from the remote, you have to do it from the controls on the projector. Hold "exit" for like 3-5 seconds and then the prompts will come up. |

I changed the bulb for this projector in Oct. of '08 but when I tried to reset lamp hours in the menu it wouldn't highlight. Now it is powering down after about 45 seconds after start up. The bulb hour life is supposed to be 2,000 hours but it only reads 1,500. Very irritating and I hope someone can help me!! |

I don`t know what the situation is in the land of the Burning Bush relating to digital terrastial broadcasting, but here in the island of b`lair we have freeview.
brought one of the little dvb boxes for about £50 which plugs into usb port on computer.
connect projector to computer via monitor output. picture quaility is great. display is set at 1280x1080.
it may seem a bit over the top way, but does have means of recording programes on timer for time shifting.
i believe there are also little boxes which also do cable and sate.
tuning is done on comupter via software provided..
405 black and white was never this good, as for bairds spinning wheel, we o have dlp. |

option one: use DVI if at all possible. DVI is pure digital. there is no conversion from digital to analog nor analog to digital. no conversion means no lost of data. and no lost of data means a beautiful image on the screen.
option two: use Sub-d 15 pin computer connection. Sub-d is NOT Digital. it is analog. there is conversion from digital to analog. there is lost of data. but quality is still good.
option three: use component. like Sub-d Component is also analog. there is conversion from digital to analog and there is lost of data during the conversion. still image is as good as sub-d.
else: DO NOT use s-video and composit if at all possible. these connections are very poor. i would say you are wasting your money running your computer and your digital projector just to get a terrible image. If you find yourself stuck at this point i would say forget the HTPC and go for a DVD player or a processor/scaller.
there. does that help at all? |

First of all I would like to say thanks to Khonas for sharing your knowledge.
Second, I would like to express my joy in knowing that an HTPC renders a better picture than a DVD player or a video processer because I am currently use an HTPC to connect to my PB7200 Digital Projector. You can say I am a computer geek, and thus I do almost everything using my computer, even when it comes to watching HDTV on a big screen. I love being able to use my computer on my big 86” and super bright 2200ANSI lumens screen. What I love even more is that I can adjust the brightness, contrast, tint, saturation, and gamma separately from the projector using the advanced properties on my ATI-9600pro video card. Thus I can fine tune my projector using my computer and not having to worry to about the limited calibration available on the projector menu.
At this point I would like to raise a question for anyone with experience with DVD players and video processors. The question is “do DVD players and/or video processors have extra features to adjust a projector that may have a limited menu for fine tuning? That is to say for example some projectors such as the one I own (i.e. BENQ PB7200) lacks GAMMA CONTROL so I connot adjust the gamma settings using the menu on my projector. However, I can go around that by using my computer’s graphics card and adjust the gamma control. That is why I wonder if DVD players and/or video processors have features in their menu that a projector may lack. If DVD players and/or video processors have more setting controls in their menu than your projector, then that’s great. Otherwise, go the HTPC way. With a quality video card you can adjust all the settings till your little heart is content and yes even if your projector lack features.
Third, here is a suggestion for checklst. If you are thinking of getting yourself an HTPC you might as well prepare yourself one that is ready for the future. That is to say, build or get an HTPC that can handle 1080p HDTV signals. Here I have quoted from Microsoft.com regarding system requirements for 720p and 1080p. or you can go there directly to do more research at
http://www.microsoft.com/windows/windowsmedia/content_provider/film/ChoosingPC.aspx
system requirements as specified from microsoft.com
Minimum Configuration
(to play 720p video)
• Windows XP
• Windows Media Player 9 Series
• 2.4 GHz processor or equivalent
• 384 MB of RAM
• 64 MB video card
• DVD drive
• 1024 x 768 screen resolution
• 16-bit sound card
• Speakers
Optimum Configuration
(to play 1080p video with 5.1 surround sound)
• Windows XP
• Windows Media Player 9 Series
• DirectX 9.0
• 3.0 GHz processor or equivalent
• 512 MB of RAM
• 128 MB video card
• DVD drive
• 1920 x 1440 screen resolution
• 24-bit 96 kHz multichannel sound card
• 5.1 surround sound speaker system
For either scenario, an AGP4x-based NVIDIA or ATI video adapter card with the most recent OEM driver updates is also recommended.
THIES ENDS THE QUOTE
Hope that helps |
