#No signal on tv lg how to
Īll of this leaves me not knowing how to proceed – LG tech support just advised the normal crap I tried above and then just gave up and said it's a Windows or PC issue. My other sources (PS3, Cable box) are picked up with no issue. I've tried multiple HDMI cables (both 2.1 and older versions), all 4 of the ports on the TV, I've disconnected and reconnected everything about 3 times, tried changing screen modes, turning Game Optimiser (in the TV settings) on and off, all with no luck. Using the same PC and the same HDMI cable I could connect to my old Panasonic G15 plasma without issues. This is a massive pain as obviously I can't be rebooting every time I want to watch something – especially as the HTPC is my main source of TV and movies. Once I do that it then picks up a signal and all is well but then if I turn the TV off or put it on standby then come back later or the next day, again the PC input says "no signal". Connecting via the HDMI port on the back panel to my new 55" LG C1 4K OLED and it will not pick up any signal from the PC unless I reboot the machine. I just rebuilt my HTPC as per above spec and at present (due to the crazy prices) I do not have a graphics card so using onboard GPU. TL DR – LG TV will not get a signal from HTPC with Asus ROG Strix B560-F Gaming Wifi / Intel i5-11500 unless the PC is rebooted or restarted.
