Hi, so I tried to use hdmi cable with my Xiaomi Mi projector - it works from a laptop, but the projector doesnt find a signal if I try from my pc, is there anything in the pc settings that could be wrong? (The TV sees the pc however)

Hi there, sorry for the delay in my answer. I hope you have already fixed the problem. Anyway here you have son recommendations if it still does not work. tecktrucks.com/how-do-i-enable-my-hdmi-port-on-my-computer/

Como es que yo puedo conectar mi proyector con un sensor y se activado por medio de el ?

[@elmaestrodetecno]

Podrías poner un enchufe con sensor pero el encedido mucho me temo que tendrás que hacerlo en el mando. Si no con un arduino y un emisor de ondas igual puedes encender y luego mandar la señal como si fuese el mando. Por qué lo preguntas? Cuál es tu necesidad exactamente?

Its not showing second screen even with this? I have new acer x118h projector trying to connect with hdmi

[@umairwagan669]

Projector screen is same no signal

[@elmaestrodetecno]

Please, check the cable is properly connected and try again clicking on the button Source Signal. If it does not work the failure could be in the cable, or in the computer, or in the projector. Check it out if it is possible for you changing one of the devices each time to find out which one is failing... Good luck!

My projector worked connected to laptop via vga, but no signal with tablet or phone when connected with a vga to USB C adapter. Any ideas why? Thanks.

[@elmaestrodetecno]

Mmm, no idea Mat22. You can also use this other method for tablets or phones ;-) kzbin.info/www/bejne/eJ2opHitqJJ0eac Or a chromecast: kzbin.info/www/bejne/emeXhaquo7-KZrM

@@elmaestrodetecno thanks for your response. I’ll check out that tablet/phone video. I wound up using an android iptv box that works with an hdmi to vga adapter with an “active” chip in it.. Whatever that is. Thanks to Reddit’s budget projector group and PlayStationPepe for the deep knowledge.

Mine works but when I update my graphics drivers it just has no signal. I'm running out of ideas

[@elmaestrodetecno]

Mm, is it possible to restor de driver to the previous version? Is the cable very long? Could you make a quick check with a shorter cable to check if that is the problem? Be sure of connecting the cable to the INPUT connector in the projector.

[@lostintime3333]

@@elmaestrodetecno I restored the driver and it works fine, so it seems to be a graphics card issue. I'll have to change the card out for a different one.
