Hello,
I would like to know, please, if projecting a DivX movie (of standard resolution and size) with a projector that has a resolution higher than the DivX, like 1024x768, will:
1 slightly improve the quality of the video
2 degrade the quality of the video by highlighting the pixel defects
3 have no influence on the quality of the video, so a projector with a native resolution of 800x600 is enough to project DivX
PS: I'm going to project from a computer; does the resolution of the computer affect the quality of the DivX being projected?
Thank you for your response; I welcome all advice
For the more motivated, I have another question:
a) Are DivX more 16:9 format or 4:3?
b) Can a 1024x768 projector read both formats?
c) Can an 800x600 projector read both formats?
d) What is the link between resolution and these formats?

Hello, that's a lot of questions. I will respond based on what I believe I have learned or understood.
I have a projector with a resolution of 800x600 and I have a new projector at 1024x768, HD ready as they say.
DivX was a great codec to fit a commercial movie onto an 800MB CD with acceptable quality (1h 30 of video) or to collect a stack of "collector" (see pirated) movies on a hard drive that one never watches. That's just my way of thinking.
I never used them because my DVD player did not accept them.
I made DVDs using an MPEG2 codec at 4GB per hour of video.
Questions 1, 2, and 3: No, an HD projector will not improve quality but rather accentuate flaws, and it will suffice to play DivX files, but to maintain the best image, it’s better to have a small TV than a 2m screen which enlarges pixels but does not multiply them.
The computer-projector connection: all recent laptops have a graphics card sufficient to play DVDs; I would recommend a VGA connection, then S-Video or, at worst, composite (yellow RCA) and an amplifier for sound.
If you want to use the mediocre "speakers" of these little wonders, an HDMI connection with one cable is practical.
You will, of course, need to align the display resolution to the same ratio as the projector when transferring the PC screen to the projector.
And since I am motivated (I’m typing with one finger with one arm in a sling), I am sifting through video questions on the site to pass the time, and I will go all the way:
The codec does not intervene in the display format of 4:3 or 16:9.
An HD ready can read both formats and even more.
An 800x600 can also read 16:9 but with cropping in 4:3 with acceptable distortion.
For the last question, I will speculate or do some research.
4:3 or 16:9 is a "ratio" of pixels (small data squares), the number of small squares horizontally and vertically (800x600 or 1024x768), and it’s the total that determines display quality. That’s all I can tell you from memory; after that, go online.
I think I have responded with simple words from an average user.
Regards.

Hello, I am proud that we understood all my explanations
I always have time and moreover it's raining in Savoie
It is objective to say that the 720 HD is not necessary for projecting DivX, the 800x600 is sufficient, I still use it for projections at friends' houses, the other one being fixed to the ceiling
I prefer Optoma since this is my second one and I am satisfied; the model proposed seems very correct in terms of quality-price
But if you have the need (and the pleasure), try to find the budget for the Optoma HD67N, it would be a good purchase to have a head start, as they say, since the 800x600 is technologically outdated and the price difference is tempting, the image is really finer
Yes, you need to align the PC resolution with that of the projector when you do the screen transfer manipulation

First of all, I want to thank you for taking the time to respond to me and for the performance of typing with one hand; I empathize because I type with two fingers and struggle.
Anyway, I'm looking to watch movies mainly in divx codec that I got from friends, which I assume were downloaded or pirated (max 700MB).
From what I understand, a large screen will enlarge the pixels and highlight the flaws of divx.
I'd still like to try the big screen; I don't want a TV, and in your opinion, is it doable with a projector for divx? (keeping in mind that I'm not looking for good image quality, but it still has to be somewhat watchable)
And, do you think it's better that:
- I get a 800x600 projector that will highlight fewer flaws but will mess up the cropping for 16:9 and maybe distort the image.
or
- I get a 1024x768 projector that will highlight the flaws but won't crop and won't distort the image in 16:9
And regarding connecting the computer to the projector, does it mean that if I take a 800x600 projector, I need to change my computer's resolution to 800x600 to enable projection, is that right?
Finally, because otherwise, I could go on with my questions, which one seems best for my use: Optoma DS 211 or Epson EB S02?
Or do you know of a model that would suit me in the low-end range around 250-300 euros?
Thank you in advance.

Hello, I'm glad we understood my explanations. I always have time to respond because, in addition, it's raining (Savoie)
Regarding the choice of projector, I always prefer Optoma; this is my second one
and for an entry-level model, the one chosen seems fine to me
for these DivX films, it's not necessary to have a 1024x720, I confirm
I reused my 800x600 for a presentation in a hall (for a wedding) with an MPEG2 SD montage and I found it still worked well. Now that I film in HDV, creating in 1920x1080, it is certain that my new projector "Optoma HD67N" delivers a "super sharp" image
the resolution 800x600 is "outdated" and if you can gather the budget, investing in HD to get a head start (it’s trending)
Yes, you need to match the PC to the projector's resolution during the screen transfer manipulation
I specify that the larger the screen, the more the pixels will be enlarged, so the image will be "pixelated," as they say, thus making the image less sharp
and vice versa.

Anyway, I'm looking to watch movies primarily in DivX codec that I've gotten from friends, which I assume were downloaded or pirated (up to 700MB max).
From what I understand, the big screen will enlarge the pixels and accentuate the defects of the DivX.
I still want to try the big screen; I don't want a TV, and in your opinion, is it feasible to use a projector with DivX? (considering that I'm not looking for good image quality, but it still has to be somewhat watchable)
And, in your opinion, is it better for me to:
- take a 800x600 projector that will accentuate the defects less but will crop poorly for 16/9 and may distort the image.
or
- take a 1024x768 projector that will accentuate the defects but won't crop and won't distort the image in 16/9
And regarding the computer-projector coupling, that means if I take an 800x600 projector, I need to change the resolution on my computer to 800x600 for proper projection, right?
To finish, because otherwise I could go on forever with my questions, which one seems best for my use: Optoma DS 211 or Epson EB S02?
or do you know of a low-end model that would suit me in the price range of 250-300 euros?
Thank you in advance.
