Hi all.I have a 65" LG tv with multiple devices plugged into it either the direct ports HDMI 1 - 3 and I have a HDMI splitter in HDMI port 4.This is a pretty standard HDMI splitter with one output and 5 inputs.I have a device on every input, so that's a each in HDMI 1-3 and 5 plugged into the splitter in HDMI 4I used to have an old Windows 7 PC plugged into the splitter and it worked fine.Recently I swapped that old PC with a much newer and more powerful PC that comes with Windows 11.This new PC will not work through the HDMI splitter.It will work if I plug it directly into HDMI 1-3.I can't

LG TV HDMI: No signal

Last night I reinstalled windows 10 2004 on my laptop. After that, none of the two LG TVs in the house will show an image through HDMI. Using Intel HD 3000 graphics. No matter what screen resolution or refresh rate of the TV I pick. However, my Telefunken
TV is showing the picture perfectly. Changing the HDMI cable does nothing.

 

4K60 signal to TV over HDMI problem


Hello!

I'm trying to connect my new PC with a LG TV (49UF7077), but the TV keeps saying "no signal" no matter what I try. The TV sees that something is connected though. And the Geforce control panel quickly and correctly finds the TV and its native resolution and other options. Windows correctly allows extended desktop and other options. I'm using the latest Windows 10 Home and an EVGA GTX 1070 with the latest driver, and checked and controlled new HDMI cable.

What I've tried:
* restarting everything
* resetting the TV
* trying different HDMI ports (although this TV clearly has one certain one which is "the right one" in terms of color support)
* disabling "hdmi ultra deep color" (something which the TV suggests as a fix)
* outputting to TV only (I also have the regular monitor on the DVI port)
* lower resolutions (as if the hardware wouldn't support 4K60)
* connecting a low end Windows 10 laptop using the same cable - WORKS!
* contacting LG support (they couldn't give a solution)

Any ideas?
