Windows 10: Impossible problem with no solution "No HDMI signal from your device" but my computer...

Dear all,I have been so happy because I purchase a new computer screen. Namely the Dell U2723QE. Super excited.It should have been an easy plug and play, but it still does not work. My computer is a surface laptop 2 consumer model 1769 i5. I am using an HDMI to min display port to connect from my Dell monitor to my laptop, however it keep saying "NO HDMI signal from your device". But as I go into the Device Manager under Monitors, it says Dell U2723QE HDMI. How is this possible? I have tried to contact Microsoft and Dell, but nobody can help me. What am I doing wrongAdditional informationI h

xbox 360 splitting video signal

Hello,

I just happened to come over your post.

Could you please tell us exactly where you don't get any signal? Both the screen and the computer (via capture device)?

Have you tried the following?

• Make sure you get a signal to the screen when using an HDMI cable directly from the Xbox 360 to the screen. Please make sure all cables work.
• Make sure you get a signal to the capture card with the same cables.

If you get a signal on the screen but not on the computer, could you please try the following?

• Set the Xbox 360 to output at 720p. The frame rate will (or should) be 59.94.
• If possible, make sure you capture the video with the same settings on the computer.
• Try any other settings if this does not work.

If it still does not work, please try this in the same order:

• Power off computer (and capture device) and Xbox 360.
• Power on computer (and capture device) and wait until the capture device is properly powered on and initialized.
• Power on the Xbox 360.
• Make sure you can capture properly.

If it still does not work, make sure that one or more of the following are not defective:

• The HDMI-VGA/composite adapter.
• The VGA cable.
• The capture device (could be just the input connector).

If that works, please install the HDMI splitter.

I am wondering a bit why you show us the wires inside the HDMI cable. Did you remove the isolation and/or do something with the wires?

I am not sure what else to suggest at the moment.

Could you please tell me/us the model of your capture device, and also the adapter between the HDMI cable and capture device?

Regards,

no HDMI signal


I have an ASUS monitor and ASUS desktop with a graphics card not on board graphics. I have an HDMI cable from the monitor to the video card. Today for the first time while on the internet my screen froze and then went blue saying no HDMI signal. I tried everything but still no signal. I then tried my VGA cable and all was working. I then tried my HDMI cable again and it worked until this afternoon when I was watching a video on the internet and the screen froze and said no HDMI signal. also when this happened I could hear my fan running loudly. Any suggestions on what the problem could be?

 

HDMI cable not detected by computer

I want to connect to a monitor or TV with HDMI. No signal to either. Monitor says "no signal coming from your computer".

I have tried with no success:

• HDMI directly into Nvidia 980 HDMI slot
  
• HDMI directly into motherboard slot, Intel i6700k with integrated graphics
  
• HDMI indirectly into HDMI(female)-to-Displayport(male) adapter, into Nvidia 980 Displayport slots
  

I have verified:

• Cable plugged into second computer, connected fine to monitor and TV
  
• Tried different HDMI cable, same results on both computers
  
• Displayport slots on Nvidia 980 work on monitor with DP-mDP cable
  
• Both monitor and TV are 4k. Output is 4k on other computer, and 4k using Displayport on this computer.
  
• Used newest graphics driver for Nvidia 980
  
• Used old graphics driver (2020) for Nvidia 980
  

All cases, other computer connected successfully and this computer received "no signal"

Other than the hardware checks and the driver checks, I am not sure what other steps I should try.

Since it applies to both Nvidia 980 and motherboard, and since Displayport works but HDMI through Displayport doesn't work, I feel like there is some issue in the computer working with HDMI signals.

Thanks, Ahmad
