Looks nice but let's get you a custom resolution to match up the image to the screen size. Leave the in-projector setting on auto aspect ratio or 16:9. Then I would recommend moving the projector back and filling out the top and bottom of the screen. Do not worry about the sides. Once the height is set perfectly then set a custom resolution to trim the sides to match the screen width.



You're not 4K but the principles are the same for 1080p.

preludesam - I have a new setup with 4k projector and retractable screen (10'H x 11'W) in my garage. I've read instructions on how to setup a custom resolution several times but can't seem to get it to work (user error very likely!). 1st - I am going home shortly to pull my projector (Optoma UHD35STx) back until image fills height. I'll change projector setting to "Auto" option. I have a monitor that I roll to the side of mat so golfer can adjust aim etc on that screen before hitting into the projector screen. I have the monitor & projector screen set to "Duplicate". I've done the math to know what I want is a resolution on the projector screen of 1188x1080. I just realized after reading this that I should be using 2376x2160 due to 4k - correct? Do I need to tell the projector that I want to use the 4k resolution or does it automatically do so if the software (FSX Play) is set up to do it? Also is there a way to not "Duplicate" the monitor and the projector screen so I get full use of monitor image and cut down sides of image on the projector screen? Any advice or pointing me towards another article would be very much appreciated.
