Screen suggestions

Greeting from sunny South Africa.

I've just recently got into the world of projectors and I need some assistance please. My setup at the moment is a Optoma GT1080HDR ceiling mounted displaying onto a 100" fixed frame with grey blackout cloth. The ambient light in the room during the day is really bad and the blackout curtains are being prepped to help with this. What would be the suggestion to try to get the best picture possible for daytime viewing. At night its pretty decent already. Pictures to follow of image at night and during the day.

The more I read the forums the more confusing its becoming. Really appreciate and help you can provide.

Pictures of image during day and night.

This was my first attempt at making a screen and will be replaced once I know what I need to do for sure.

There's a few screen surface types, but of the four main ones I'd suggest a white matte screen which are known for their light diffusion. Depending on the glare and projector angle, matte screens pretty affordable.
You can do NOTHING to or with the projector or screen to make the "daytime" result better... you have a lot of light in the room, period. The only way to make the picture better is to make the space "black" period. And what the **** is "gray blackout cloth" and exactly where is it? Screen frames have black light-absorbent velvet on them, not "gray" anything. There is a type of screen called "ambient light rejecting" but that type of screen can't possibly deal with the amount of ambient light you have in the room in the photos... HALF that much stray light would still be too much for an ambient light rejecting screen. What you really want is an 85-inch diagonal flat screen TV that can produce over 2000 nits of luminance. There is no projector on the planet that does justice to high dynamic range content... projectors are too dim (expecially a when you use a modest cost projector with 100 inch diagonal screen, you are probably viewing peak white levels around 10-12 fL (30-40 nits) when high dynamic range doesn't even begin to start looking impressive until the video display can reach 1000 nits, your projector setup is over 900 nits away from that milestone. Then there's the issue of the imaging tech you chose. Optoma uses DLP imagers. They natively have much worse (grayer) black levels than reasonably good LCD/LCoS projectors like those from Epson. So you are fighting a projector that does not have a very impressive black level (unless you use a VERY large screen as you have done, with that very large screen then becoming very dim because the projector just can't deliver a lot of light at modest cost to fill a 100 inch diagonal screen. Some forseeable number of years (5 to 7 is my estimate) in the future, projection is going to disappear entirely as displays are assembled from tiles that snap together to make screens as large or small as you like... and they will be 100 times brighter than today's projection systems with "perfect" black levels in any lighting. Honestly, this is a bad time to be poking at projection and projectors because they are going the way of the plasma TV, the laserdisc, et al. Even movie theaters will be removing projectors and replacing them with snap-together screens that make their own light/images.

I agree with the above post. You only have two options. Get the room darker, or get a much brighter projector. Even with the brighter projector, blacks will look washed out until you get the room dark. Screen fabrics/finishes will have only a very modest impact. Bang for the buck, room darkening window treatments are the best. Good luck!
Looks like a lot of light coming from the right. Figure out how to block that from hitting the screen. Black-out curtains (room darkening), possible big squares of cardboard you could put into / over window while using projector, if possible move screen. You could try an ALR (ambient light rejecting) screen. This will help some. A brighter projector may make some difference. If screen position cannot be changed, then probably the best 'band-aid' will be a combo of of all 3 work-arounds.
