We have set up our new Vava 4K projector with a 110" screen (“SD” distance, as per the manual). Since there are no details for a 110" screen in the “Projection Distance & Image Dimensions” table on page 05/06 of the user manual, I interpolated between 100" and 120". The numbers I came up with (which then fall between the numbers for 100" and 120") are:
Device-Wall Distance (W1): 9 1/8" (23.0 cm)
Image-Desk Height Gap (H2): 13" (33.0 cm)
Desk Height (H3): 11 9/16" (29.3 cm)
This places the bottom of the image at 24 9/16" (62.3 cm) above the floor; ie H2+H3
For the desk height, we actually trimmed down a small coffee table to 11 9/16" height (H3). To install the screen, we first projected the image on the bare wall using the numbers above, then used tape to mark the image position on the wall, and then installed the screen accordingly.
With this, we get a very good image, nicely centered on the screen. Except - Except that we think that this places the image too high for the viewer’s line of sight. We find that we are needing to look slightly upward to watch. So I’m thinking that the Desk Height (H3) actually needs to be lower for best viewing; the H3’s in the table in the manual are a bit too high.
I’ve thought of temporarily just placing the projector on the floor (ie, H3 = 0) to see where the image falls on the wall, and then just eyeball what would be a good H3, somewhere between zero and the current placement of 11 9/16".
Any and all suggestions would be welcome. Thanks.
