- "Better picture quality" means higher resolution or "looks better"?
Same resolution, but better. Probably more clear, more clean.
- does the input from DVI and VGA both can come out the same
resolution or not?
Same. |

--VGA 15 pin is transfer singal in analog mode.
--DVI transfer singal in dihital mode.
--So DVI should be better picture quality.

back to my question, does the input from DVI and VGA both can come
out the same resolution or not?  |

--Don't use graphic card's S-video output to projector. The best you
can do is to set your PC's resolution to 848X480 and connect to
4805's VGA (15pin) input.
I mean for the projector that has both DVI input and VGA(15pin)
input, does it matter if I use DVI input or VGA input if I connect
it with my computer? This means if the projector supports 1240x768,
both DVI and VGA input can come up with that resolution? |

Generally speaking, data projector is brighter. It has the side
effect to make you feel it is sharper. |

- 我張卡系ATI Readon 9800 pro,網頁上寫說TV out可以出到1024x768
That probably means it can "所謂支持" 1024X768. Actually it down
converts 1024X768 to 480i output
- 原來看電腦的影像文件,例如rmvb,avi,mpeg等等的電腦影像文件用data
projector比video projector還要清晰?
I thought you were talking about normal document such as MS Word or
Powerpoint. 
If you are talking about video document, most of them are 720X480,
640X480, or even 320X240, so 4805's 854X480 is good enough.
- 如果用普通那個15針的電腦插口能否做到1024x768的效果?
4805 will down converts it to 854X480. Beside, this is analog, not
as clear as digital (DVI).
-所以想一系用15針的電腦普通插口,一系用s-video出. 唔知道邊種好?可以有
几好?

- 我張video card經 s-video出到1024x768
--That's not true. S-video can carry 480i and 576i only
我張卡系ATI Readon 9800 pro,網頁上寫說TV out可以出到1024x768, 如果唔
系s-video,應該就系dvi直出了. 這個解像度是否無須任何軟件(除了本身的驅
動程序)來提升呢?
--Then you need a data projector rather than a video projector,
--which has resolution of 1024X768 and up
可否舉例几部呢?(最好系經濟少少)..
我一直以為data projector系給office用,看"字"比較清楚, video projector
系給家庭用,看影像比較清楚.原來看電腦的影像文件,例如rmvb,avi,mpeg等等
的電腦影像文件用data projector比video projector還要清晰?
我見到那些projector後面通常有兩個這樣的插口:15針的普通電腦插口和dvi電
腦插口(或者HDMI, M1), 如果用普通那個15針的電腦插口能否做到1024x768的
效果?(以9800pro為例). 因為只有一個dvi插口,給dvd插了就沒有了.雖然現在
有dvi的kvm了,但是太貴了..  ,所以想一系用15針的電腦普通插口,一系用
s-video出. 唔知道邊種好?可以有几好? |

What is your throw distance and your expected image size? |

- 甘樣出來的效果好像有d取巧
The resolution of the display most of the time is not the same as
the source. Scaling is always needed, that's not 取巧
- 我主要系駁電腦來看電腦上的影像文件
Then you need a data projector rather than a video projector, which
has resolution of 1024X768 and up
- 我張video card經 s-video出到1024x768
That's not true. S-video can carry 480i and 576i only
- 部4805好像唔系好夠甘
For PC desktop, yes. For DVD video, it is good enough.
- 經過這條線會唔會降低畫質?
No, M1 carry the same digital video data as DVI |

>4805沒左那個dvi插頭(需要另外買那個m1轉dvi的插頭,甘樣讓我感覺好搵
笨....
買z201e啦  |

- 照你講,甘所謂支持的格式未好多餘?
唔支持就連公仔都無. 你要支持:有嘢睇, 定唔支持:無嘢睇?
而家所有15萬樓下數碼投影機都係睇唔倒1080線, 如果唔支持1080i, 就連公仔
都無得睇. 咁你話所謂支持的格式係未好多餘? |

恩, 但是現在覺得甘樣出來的效果好像有d取巧.同埋我主要系駁電腦來看電腦
上的影像文件.而且我張video card經 s-video出到1024x768,部4805好像唔系
好夠甘...

AE500係1280x720 native 解像度, 所以出720p(1280x720p)係1:1, 冇像素轉
換, 但出1080i(1920x1080i)就會有啦!咁部機支援多啲解像度其實都係好事,
起碼有嘢睇(雖然唔係最靚), 重有而家睇到嘅主要訊源(dvd, 電視廣播等)都係
480線(NTSC)同576線(PAL), 數碼廣播要幾年之後先有, 如果剩係用嚟睇碟,
infocus 4805都勝任有餘  |
|
唔理玩單槍定三槍, CD 定SACD, 兩聲道定7.1都好,
都係人玩機, 唔係機玩人

yes, it is the Infocus 4805 specs,
照你講,甘所謂支持的格式未好多餘?因為根本就出唔到那個等級..
甘樣未就算系panasonic AE-500都出唔到真正的1080i or 720p? |

No matter you input what resolution, it will scale to 854x480. For
720P source, it will downscale to 854x480. For 480P (720x480)
source, it will upscale to 854x480. |

我看到投影機的網頁有其播放的解像度:
Native: 854x480 Pixels
Maximum: 1024x768 Pixels
但是我同時又見到部機support 1035i, 1080i, 720p, 576p, 480p, 480i
我想問下點解854x480可以出到720p? 720p唔系需要成19xx以上咩?
另外native 同 maximum,系唔系只是看native就可以,maximum系唔系永遠做唔到,只是一個參考值?
