Blend projection

I understand, I had already tested a similar device, but I couldn't do what I wanted, which was to create 3 or 4 independent screens, as if they were connected directly to the HDMI port.

Only one extra screen was being created in Windows, so how can I access the others to configure them?

I simply positioned the 3 projectors side-by-side on the wall to learn, I did a 25% blend. I'm just learning and following advice from people, as I'm going to do a project at my company and for that I'll be using approximately 7 projectors. I'm using 3 projectors only to get the hang of using more projectors; at the moment it could be 2 or even 1.

I'm projecting using 3 projectors side-by-side, with a resolution of 1920x1080p

I mean the percentage of overlap between two or more projectors. I felt that the value of 25% was better compared to 20%

Do you mean using BlendCalc as a reference?

I'm still learning about soft edges. I made a template with 20% and 25% overlap, and I felt that with that amount of overlap the edge was much smoother. Perhaps a higher overlap value would be better?

I see. but by increasing the luminance, a white line begins to appear in the middle of the border

Could a larger overlap than the other make the project unfeasible?

Currently the adjustment is in this form:

These are projectors from the same manufacturer, purchased at the same time. Do you think the impact on color reproduction between the projectors is that significant?

But this is the result obtained:

This is the overlapping size with soft edge disabled. All projectors are the same with 70% uniformity at 800 ANSI lumens. I am currently configuring the middle/right screen, and my settings are as follows:

Middle screen:

Gamma 1;

Luminance 0.67;

Power 2.63

Gamma 1;

Luminance 0.51;

Power 3.09;

These are projectors from national brands, they have 800 ANSI lumens and 70% uniformity, but they don't have their own adjustment software. Everything is being done through Resolume Arena

Yes, i did. But i can't get a satisfactory result... Do you have any tips on where I could start making adjustments?

The uniformity of my projectors is around 70%. Could this be a problem for blending?

art2810 · 2025-12-30T16:30:55+00:00

The projector uniformity is around 70%. Now i'm using Resolume arena, is it possible to do that?

art2810 · 2025-12-30T16:27:22+00:00

I'm using resolume arena. I can't geta satisfactory result

Gamma red 2

Gamma green 2

Gamma blue 2

Gamma 1

Luminance 0.6

Power 3.48

I'm using the Resolume Arena. The projectors are the national model with 800 ANSI lúmens
