Hi all, looking for some advice.

My 120” fixed frame screen is basically locked in at this point. I’ve got towers on both sides and a center speaker underneath, so there isn’t really anywhere else for the screen to go.

There’s a track light running down the middle of the ceiling, pretty much right where I’d want a centered mount. It’s also the main lighting for the room and we use it every day, so taking it down just for the projector isn’t really happening.

The spot that works best would put the lens around 10.5 ft from the screen and about 16–18” off center. I’ve been looking at the N3 Ultimate since it has lens shift and optical zoom, but I’m not sure how far I can actually shift the image sideways.

Trying to avoid keystone if I can. Think that offset is manageable, or am I pushing it?

Hello fellow JMGO users!

I recently got a JMGO N3 Ultimate on sale and have been trying to get it to project into the ceiling. However every time I hit the AI mode it tries to project it down onto a wall. Any tips here? I also want to know if you guys have any tips / best color set up suggestions as my blacks seem... splotchy?

(1 texture, 3 arithmetic)

Apply when the picture is too dark.

Increases brightness without clipping (Black point and White point are unchanged).

Photoshop Screen Blend, brightness/contrast curve:

out = -Screen*x*x + (1+Screen)*x = -Screen*x^2 +Screen*x +x

with x, out: pixel.rgb in [0, 1.0]

and Screen >=0

parameter Screen [-1, 1.0], 0: no effect.

>> Positive: (Screen Blend) increases brightness, increases constrast in shadows, ex: 0.24

- Brightness increase is maximum at the mid-point (Screen/4).

- Contrast = 1+Screen -2*Screen*x

Contrast is maximum at the Black point (1+Screen) and decreases linearly with input level.

Contrast:1 at the mid-point.

negative: (Multiply Blend) decreases brightness, increases contrast in highlights.

sampler s0: register(s0);

#define Multiply -Screen //to ensure a positive user parameter.

float4 main(float2 tex: TEXCOORD0): COLOR {

float4 c0 = tex2D(s0, tex);

c0.rgb = lerp(c0, c0*c0, Multiply).rgb;

return c0;

}

Before I got the n3 ultimate, I was pretty sure I’d end up buying blackout curtains. I kept seeing people talk about blackout curtains and dark walls whenever I looked up projector setups. Two months later and I’m still using the same thin curtains in the living room. They still let some light through when they’re closed, but it really hasn’t bothered me much. Maybe the screen is helping too.

Most of my movie watching is at night anyway, and I’ll sometimes turn the brightness down a bit. I still use the projector during the day sometimes and it’s been fine. Direct sunlight is obviously a different story, but outside of that I haven’t really had an issue. So far I haven’t seen much reason to replace them.

Getting my N3 Ultimate set up right now. Apple TV and UB820 are both going through the AVR, and I was going to do the same with the PS5. The N3 supports VRR, so I’d like to keep that working. I’ve seen a few people connect the console straight to the projector though, usually because the AVR causes handshake or VRR issues.

Anyone here running a PS5 through an AVR into the N3 Ultimate? Curious if everything’s been working normally or if you ended up going direct instead.

I'm seriously considering buying the N3 Ultimate but I read about judder in some reviews

Is this something I should be concerned about? It would mostly for watching movies etc

Many thanks

There is no option to ship to Canada, and no other retailer has it.
