using the 7 inch 720p projector.
Tried the cheap 10m HDMI cable that cost only $14
1. Using laptop , there is occasional flickering
2. Using bluray , perfect! No problem at all!
Since I wont be using PC, I will proceed with the installation of this cable in the ceiling.
Now here is the most exciting part.
The wall is up but still no white paint, the wall measures 177x108 inches. The wall is brownish. in color. So I put a bond paper at the center so I can have a feel of how the actual image look like later.
I invited a friend who stands 5'7" tall to stand in front of the wall for sizing up!
There is still no power in the home theater so its really very hard to do this test.
Now for the test set-up.
1.The projector is 19ft from the wall
2. The height from the ceiling to the projection lens is 2.5ft.
3. The image dimension is 136 x 86 inches with diagonal image size of 160 inches
4. I use the OHP lens F-240. I will use this so that the projector will be at the back of the seating position. What fascinates me now is, at a distance of 19ft from the wall, the focus is almost perfect from all corners,sides and center. I had been thinking all along that if you are just using 80-120 inches screen, the best projection lens focal length to use is F-260, but unfortunately, I can't find a F-240-260 fresnel.
5. There is no lens shift. or tilting of fresnel.
6, Using 18,000 lumens 128w led. This led is production sample with wrong or bigger array size than the 15500 lumens led.
7. I sold the adjustable focus earlier because the focal length is only a sample. But brightness,resolution and sharpness wise, its much better than the ohp lens.
I can only see the real brightness after painting the screen. But so far, with the bond paper at center, i can predict the brightness,whiteness and colors will be very good. The colors are stale with brownish wall.
So here's how big the image is!
