ViewSonic X10-4K short throw projector
« on: Sat, 23 Mar 2019 15:02 »
Just released ... looks very interesting with about 50ms input lag. Might be a nice upgrade to my 1080ps, but worried about the slow input lag.

Got very excited until I found out the throw ratio is 0.8.... my current 1080p projectors are 0.5 :-(

Ah I have the Optoma GT1080E so will need to move around a bit.

hey Gary, this new projector Xiaomi Mijia 4K has a throw of 0.233:1, but input lag is over 90ms. Not sure if that matters for flying?

Interesting...

Are we now at the point where 0.2 is too short throw for a curved screen to work?

Also it says 5000 lumens but only 1500 ANSI for picture source?  Anyone brave enough to give this a go for £1600?

Cheers

Does anyone have access to Immersive Designer PRO to see if the throw would work on a curved screen?

there's a great review here https://youtu.be/O8pMMRVLSyA

Absolutely!
I had purchased 3 optima gt5500+ projectors with throw ratio of 0.25:1 to go with a Natvis curved screen . The projection was terrible with this setup. I sent the gt5500+ back and went with 1080gt darbee versions with the longer throw ratio as the setup was originally designed for.  I thought going with the ultra short throw would create a 210 degree visual system no problems, Instead I ended up with a view that was unworkable due to an over exaggerated bow of the image from each projector.



The red outline indicates the view when using the ultra short throw. As you can see, the keystone was uncorrectable even at max settings.

The gt5500+ uses a reverse mirror to project at such a short distance, as does the Xiaomi Mijia 4k ultra short throw. I'm sure the result would be the same just at a much better resolution.

Thanks Hoppie for adding the pic.

very interesting. regarding input lag, would over 80ms be acceptable for flying?

The FAA's maximum lag tolerance for the visual systems of a level D simulator is 150 ms.

Also, this value is more important to smaller, highly responsive aircraft than to heavy aircraft with great inertia.

For reference:

Thanks Hardy, very useful info. I am tempted by the ViewSonic X10-4K which is more of a standard short-throw projector. Shame they stopped doing a demo for Immersive Designer PRO  :-[

All,

I have just taken the plunge to fit these to my simulator after finding them for £1000 each in the Black Friday amazon sale.

Wow wow wow what a HUGE difference from the optima 1080s.  Amazingly clear and so much brighter.  Have also been able to turn off anti aliasing and get a performance boost enough to raise the settings in p3d :)

The 0.5 to 0.8 throw actually wasn’t much of a problem after moving my projectors back about 10 inches.

My screen was probably far too big before.

Cheers
Gary
