Any way to increase projector image size?

Hi I have a HW40es and I'm at its maximum range of wide angle. However I still need a few more inches to fill in my screen. Is there a cheap lens adaptor I can buy which can aid me in this or am i stuck?

I've heard of the mirror trick but it wont work in my setup.

Can you move the projector mount closer to the screen or move the screen closer to the projector?

If needed but shouldn't I be moving them farther away to increase the image size?

Oh yeah, my bad, you are right. Farther back would give you a bigger picture.

Why won't a mirror work in your setup? They're are a lot of configurations that are possible you just need to think outside the box.

Mirrors are a major pain and can cause artifacts, absolute last resort.
They are also usually a bit of an eye sore in an HT room.

Eye sore and just huge space constraints in my current setup

How big is your current screen and what aspect ratio?

The bottom line answer is 'no'.

There's no cheap way to do this effectively. You can certainly buy a wide angle adapter lens, of large enough size, but that will cost you quality like nothing else. Similar to a mirror bounce, or likely worse.

This goes back to measuring twice (or thirty times) and buying once. In your case, you will have to go smaller, or go with a mirror bounce. I'm not familiar with real world wide-angle lens testing, but there is a thread...

Yes, that thread is ancient, but believe it or not, the link to the .7x Sony adapter lens is still good. So, you may be able to get acceptable results going that route if you just need a foot or so more. But, you will need to take care in positioning the lens.

Thanks.

I have a 95 inch screen and a HW40Es at around 2.7m so I'm going to assume a 2.7m throw producing a 90'' image approximately so its not the end of the world i guess. just a bit of a bummer i couldn't squeeze out an extra 5''.

i cant think of another PJ which can give me the extra 5'' except the panasonic ae8000 because its so tiny.

Many of the DLP's have a shorter throw and will fit well into your throw/screen size like the BenQ 2050a or the 3550 for 4K. Some LCD's will also work but no LCOS that I know of.
