hello, I am new here this is my first post and i would really appreciate some help.
I have a Optoma UHD35 projector 2021 model and a hp spectre laptop on windows 10 (4k resolution, about 5 years old) and when i connect them via HDMI all i see is a no signal message on projector screen.
When i connect my laptop via hdmi to my tv or my other projectors (even 4k ones) it all works fine so i know the hdmi output works fine.
I tried many different hdmi cables (none longer than 5 meters) even the most expensive ones but nothing seems to help.
The projector only projects a no signal message.
i tried the basic hdmi handshake troubleshooting with booting the device while connected in different orders and turned off auto searching on the projector but no luck.
Now the thing that is really weird is that my laptop knows it is connected, while connected via hdmi the screen blinks and optopa UHD35 is listed as an audio output option. the other weird thing is that while trying out different things i resorted to unplugging and plugging the hdmi back and forth in my laptop output. one of the tries was succesful and i got the picture projected perfectly (on around the tenth attempt of replugging the hdmi) everything was working smooth until i changed the laptop resolution while it was being connected from UHD to full HD because i wanted to try the 3D feature. the second i clicked approve on the change resolution pop up message the picture got disconected and the dreaded no signal message appeared again. Since that i changed my laptop resolution back to 4k and tried unplugging and replugging about 1000 times but zero luck, i never got the conection to work again.
I know this is a lot to read but i hope someone will take the time to reply, I am really desperate as i paid over 1000 euros for the projector and the salesman said he couldnt help me with this issue since i had already gone through the basic troubleshooting and he doesnt know what else there is to try.
thanks in advance to anyone who will reply
