I got an LG ultra short throw projector. It has a very high requirement for the flat surface, otherwise the image will be distorted, which is unfortunately the case of my wall! After doing my research on google, looks like Fresnel hard projection screen is the optimal choice. This type of screen eliminates the ambient light from the top and both sides of the screen, so it's perfect for ultra short throw projector, which is normally placed at the bottom of the screen.

However, Fresnel hard projection screen is basically a piece of glass, so it's extremely expensive to ship from overseas. Looks like only some China companies producing such screen. I'm wondering how I could get it in NZ? Alternatively, any other choice do I get? I'm only into hard screen. Thanks!

If its glass your after talk to a local glass manufacturer (Like Metro Glass or Viridian) and specify Low Iron glass (the iron content in std glass gives a greenish tinge)

Thinner is better, try not to go over 5mm thick, and DO NOT get it tempered (will create a wavy surface)

Simply ask them to backpaint the glass white, then talk to them about wall mounting options (A powdercoated channel top and bottom for example)

You'll save a bundle...

Have you tried any specialist HT shops? They may be able to advise you what your best options are for UST projectors.

As an example, Rapallo sell a range of screens https://www.rapalloav.co.nz/product-category/default-category/visual/projector-screen/, including fixed ones like this https://www.rapalloav.co.nz/product/100-inch-slim-fixed-frame-screen/

Edit: also more affordable options at AV World - https://www.avworld.co.nz/shop/category/projectors/screens/fixed-projector-screens, but as to whether they are suitable for 4K and/or UST...?

But, yeah, they're not cheap, so I'd be interested to know if having one 'made' by a glass shop works. (Would the reflectivity not be simply too great?) In the past I've come across instructions for self-made screens, but I think that was feasible with lower-res projectors, with no need for the tiny tolerances I'd imagine are required for a UST image.

BTW, where did you get your LG projector from, and what did you pay (if you don't mind me asking!)? I assume it's their 1080 model? I see they revealed a 4K model at CES earlier this year, which looks great.

I'm increasingly interested in a UST projector when it comes time to (ie when I can afford to!) replace my current TV (so please do post back with what you end up with for a screen) - I want a large image, but the price of large OLEDs is prohibitive, and I've no interest in the hassles of mounting a projector on the ceiling.

I know Xiaomi have received decent reviews for their UST projector, but I'm really not sure when or if I'll be comfortable spending that much on a Xiaomi product!

My projector is LG PH450U bought from USA. it's a 720P model not 1080P. From 2m distance I cannot see much difference. The LG 1080P model does look much brighter. Running in full power, PH450U is already quite bright, I need to lower its brightness a bit so my eyes won't get pain. The problem is the screen. I will try some DIY solutions before I report back.
