It's possible that the issue lies with the HDMI port on your Dell laptop. Have you tried using a different HDMI port on your laptop, if available? You can also try updating the graphics driver on your Dell laptop and resetting the display settings to default. Additionally, you can try using a different HDMI cable to see if that solves the problem. If none of these steps work, it's possible that there may be a hardware issue with the HDMI port on your Dell laptop and you may need to contact technical support or bring it in for repairs.
Hi! I'm having a problem with connecting my Dell (G15) with a projector (Vivitek) Two days ago I could connect it but today it stopped working. My computer recognise another display, but the project didn't "catch" the signal. We try different things; I connected my Pc to other projector with other hdmi cable, and we connect the Vivitek with another computer (with the same hdmi from the first attempt) Everything worked. The problem was between my Dell and the Vivitek. (Also, I tried the old trick of shut down and turn on, just in case)Thank you very much!
