I'm currently looking for projector for conference meetings in a hall no more than 100 persons. We actually do have 2 halls - one of them is for 30 persons. I need to be WXGA resolution with at least 2700 lumens
I've looked at couple of projectors. I've seen that in these forum you recommend Panasonic, don't know what I'll get more by getting one for my use. I prefer to be short-throw. Thank you.

The BenQ is DLP which means that the color brightness isn't close to what is listed.

Not sure on the Panasonic model.

But, I would be looking at LCD and I would look at this list:<g=&t=&db=&dt=1.0.0&c=&ar=Wide+%2816%3A9-10%29&dvi=&wr=&sp=14&pjl=&pjw=&pjh=&td=&is=&i=d&tr=&oop=2&sort=brt&sz=15

The NEC right at the top is a very good option. It's very bright and will be a far better way to deal with ambient light issues in a typical board room/training room scenario.

Here's the deal. You want about 80 advertised lumens, minimum, per square foot of screen space for acceptable results. Not 'best' results, but acceptable results.

Short throw projectors aren't designed for larger screen sizes. They are designed for interactive white boards. By far, that is what they sell into. Ten thousand classrooms vs. a few one-off designs. So, that's what you are running up against with short throw.

The NEC can focus up to 110" diagonal, which is a pretty reasonable size for many environments.

There are many short throw models which can go 120"+ in size, but with 2,700 lumens, they won't actually be bright enough to deliver a quality image at those sizes.

You have the other issue that short throw projectors need a very flat screen to work properly. The severe projection angle plays havoc with any waves in the material.

While I'm not telling you to ditch short throw, I would likely switch to a standard throw model...<g=&t=&db=&dt=1.0.0&c=&ar=Wide+%2816%3A9-10%29&dvi=&wr=&pjl=&pjw=&pjh=&td=&is=&i=d&tr=&oop=1&sort=brt&sz=15

Something from that list would be my recommendation.

Which is also why this model is one I typically recommend...

It's bright enough to make an impactful image at 120"+ diagonal. It's inexpensive, and it's a quality brand.

OK, thank you. I'm going to buy Epson EB-W18 or maybe W22, W28 models.
I want to ask you, if they're 1280x800 with 16:10 format, can I use them with 16:9 screen, or I need to buy 16:10 screen, because the laptops are 1366x768. In the conference room we output typically 1280x720 resolution.

BTW as you said LCD I've found other models from Sony and Panasonic
