Blurry image with projector Solved

Question

Hello,

I purchased an Optoma DLP projector. I wanted to connect it to my computer to watch movies on my wall. So I plugged it in with my computer’s VGA port, and I adjusted the focus (dial on the device). However, I have a problem; I looked through all the settings on my computer and the projector, and the focus is already at maximum (the dial can’t turn anymore, and on the other side, it’s worse..) and the image is blurry!
Blurry to the point that I can’t make out the names of my movies in my folders.
On the brochure (or rather on the website: https://www.topachat.com/accueil/index.php where I bought it), they say the projection distance can range from 1.2 meters to 12 meters! I measured, and I am projecting at 2 meters. So, is it false advertising or a bad setting?
I thought about changing the screen resolution (currently at 1280x1024) to 800x600 (its native resolution) and then setting it to native. But the quality remains poor... It’s not a matter of contrast or brightness; I’ve already fiddled quite a bit with those types of settings.

Thank you for helping me, because in the end, we bought a machine for €270, and it doesn’t work. It’s quite frustrating..

Best regards,

Configuration: Windows XP SP3 / Firefox 3.6.13

I cleaned it, and while disassembling it I saw there was a second focus ON the lens.. (Obviously, as there’s no documentation, you can’t know). So, the focus is perfect now! Thanks anyway for your answers ^^
Have a good evening!

Hello,

The problem is that you have outlined possible solutions in the description of your issue.

The last thing I can suggest is to play with the projection distance, if you haven't already. For example, what does it look like at 4 meters?

I'm afraid of the answer, and I really find it outrageous that at this price you can't get a minimum of quality.

At 1280*1024 it should be clear at about 3 m. At 800*600 at 2m.

Sorry I can't tell you better, but I'm afraid you may have unfortunately ended up with a real piece of junk.

Oh, and I specify that I also projected at 4 meters and it didn't change anything.

Well, I'm going to try it natively at 800x600 further away.. But that's going to require me to do some work at home to be able to project correctly... u_u

In that case, there's only the disassembly / cleaning of the optics left (that can happen), but I don't have much faith in it...

It's nine.. So unless it was in a dirty warehouse and not packaged, it would be surprising for it to be dirty.

We agree. But still, even if it's not HD, you should have a minimum visual comfort in this price range. I admit I'm struggling to grasp it. Are you using VGA or DVI?

I'm using the VGA port (the one for computer screens, you know). I had also considered the HDMI port. But still! I'm in high school and my teachers use VGA projectors too, and it looks very clear!

By the way, speaking of HD, it's written that it handles HD. But, well, I'm not too sure about it now. Still, I'm going to try to clean the lens, you never know.

Glad it could solve the problem :o) -- The more confident you are in your ability to make a machine work, the more you look like a fool when it fails...
