What to do about projector light outside of screen border

I assume that this question has been asked and answered many times on this site. I have looked, but cannot find the information I need (maybe I don't the correct search terms). So I apologize if this problem and the solution has been widely discussed in this forum and I am adding yet another post on it.

I have a very simple home theater setup in my basement. It consists of a 120 inch screen (16:9) I got on Amazon and an entry level Epson projector. The image is satisfactory but the projector throws light outside of the actual image. In other words there is a skewed border of light that falls outside of my screen and border. I have tried everything to correct with the projector settings, but have been unsuccessful at getting rid of that extra light.


The projector is a standard 4:3 aspect ratio. I have set the aspect ratio to 16:9 using the settings. Also, I have used "quick corners" (kind of like keystone) to square up the image to the screen. It suspect that my project placement is a bit off center and the adjustments I have made have exaggerated the light border.

Finally, the wall painted with white paint. As such it is very reflective.


I am trying to figure out how to hide the light ring around my screen. I have thought that a non-reflective paint or some fabric panels may absorb the light and make it less noticeable.


I would appreciate any suggestions on how I might fix this issue.


Thank you!

2 more questions

Thank you both for your responses.


I have tried the zoom and the light ring also expands/contracts in proportion to the image. So I wasn't able to get that to work.


The screen I have does have a black velvet frame, and I noticed how well it absorbed the light. So two follow up questions if you don't mind.


First, is there a particularly good source for black velvet?


Second, any recommendations for how to apply the material? I thought about making Styrofoam panels and wrapping them in the velvet. Then adhering the wrapped panels to the borders of the screen.

You can do panels as you suggest or hang the velvet like curtains. I have my projector in the living room which is white. I applied 1/4" plywood panels wrapped with velvet to the ceiling and hang velvet around the screen and side walls when in use. To facilitate the removable curtains I embedded 2" wide strips of sheet metal I bought from a HVAC company that had an 8' break to cut the strips. Then I attached neodymium magnets to the back of the velvet panels with white gaffers tape. The white tape was used so as not to leave black marks on the wall and it is more flexible and sticky then standard duct tape. Your ideas of attaching the panels to the fixed frame or inserting them behind it would look very nice and professional.

You can get velvet at a good price form Joan Fabric with a 50% off coupon or order it from SY fabric but you will pay shipping http://www.syfabrics.com/View.aspx/Plush-Triple-Velvet/Black-Plush-Triple-Velvet/681/264
Use 3m 77 spray adhesive to affix the velvet. If you follow the direction on the can it works very well. Should you do a single large panel it is really helpful to have someone assist you. Once you apply the velvet you can lift it and smooth it. Do several small test panels to find the best way to do it without getting any adhesive on the front of the velvet as it will melt the velvet pile.
Here are some photos with comments under them once you click the thumbnails that gives you some ideas on what i did and may inspire you with some ideas.
Good luck and it is worth the effort.

You can also make a black frame with a 16:9 hole cut in it and mount it a few inches in front of your projectors lens.

Take something and hold it up there to shadow the bad areas as an experiment and you will see how that works.

4:3 projectors have a 16:9 setting that shut off the pixels not needed but they do not shut off 100% and will shine a little light. better to block them.

Lastly I would move the projector to the proper location rather than using the 4 corner adjustment. Using that or even keystone takes away some of your resolution and using a 4:3 projector you need all the resolution you can get.

Hi I fixed this problem make a cardboard cut out and put it over the lens that cuts out the over spill of light you can experiment with the edges and you will see where you need to be then make an accurate template out of cardboard, I can't understand why all projectors have this problem but it is a very easy fix .
