Windows 10: Can't "duplicate" when using a projector ... only Screen 2?

I got a new Lenovo running Windows 11. When I hooked it up to a projector using hdmi at both ends, the screen flickers and has many weird lines IF I duplicate the display on my laptop or use Screen 1 only. If I switch to screen 2 only, everything is crisp and fine, but I can't see the laptop display at all, to control the projection from the laptop. The projected screen becomes the only place I can control cursor, etc. How can I set the laptop so I can duplicate display and have both the projection and my laptop display working at the same time?

Duplicate laptop screen on projector screen

When I connect a projector to my DELL XPS Laptop it does not duplicate the laptop screen on the projector screen. The projector screen says no signal

When I select extend screen it works as I would expect.

What can I do?

 

Projector Screens

So I just got a projector. It's nothing special, just an old Dell 2300MP. I mainly got it because it was only a couple hundred bucks and the biggest screen I previously had to watch movies on is my 24" LCD. Now I'm trying to decide what to go with as far as a projector screen.

The previous owner recommended painting a bed sheet stretched over a wood frame. Hundreds of retailers and Ebay sellers have projector screens of incredible price variance, and even more web sites and forums have instructions for DIY screens. I've now read about more kinds of paint and materials than I previously knew to exist.

Finally, overwhelmed, flabbergasted, and with a slight headache, I decided to come and ask my good friends here at TPU. What do you guys suggest for a projector screen?

Things to be aware of:
· a dark environment is available; this will be going in a basement room with no windows
· I'm removing the wall paneling from where this is going an replacing it with sheetrock or whatever is recommended, if using the wall as the screen is suggested
· current projector may be unimpressive, but may be replaced with something better/higher res later on, so I still want to do this as nicely as possible in my budget
· my budget is only ~$100, but so other people can be helped by this topic as well, general advice and all ranges of projector screens are welcome
· for the sake of room acoustics, I would prefer a screen that does not reflect a lot of sound, so some type of acoustically transparent surface (fabric) would be ideal, but I can work with anything (acoustic foam will be elsewhere in the room, amount and placement dependent on other factors including this screen)
· due to room limitations I can only place the projector about 15' from the screen
· for noise control, the projector (and computers) may be placed outside the room and project through a window—I'm open to suggestions on said window (plexiglass?)

All in all, I have found a lot of experience, insight, and knowledge resides here at TPU so I hope to get a good conversation going that will help others on this topic as well. I'll update this first post with the most useful info put forward in this thread.
