Pc hdmi no signal on tv Pc#
I tried to boot when the TV is on and the source is set to the right HDMI port and I get a 'Cable not connected' to 'No signal' when the PC is on. That mean the PC boot perfectly and that video card and cable works. And it worked.īUT: The problem is, that the effect does not persist. The PC and HDMI cable are working perfectly because I tried them with a PC monitor of a friend. When I read it, I thought it was internet voodoo that would never work, but there were dozens of comments underneath that post thanking the guy. You really have to wait for quite some time. Note that just unplugging the power and immediately plugging it back in does not help at all. The following may sound really strange, but: I found a blog post (see here) that suggest to:Ġ) Connect both the HDMI and DP cables, then start Windows using HDMI modeġ) switch to display port using the OSD (will give no signal message, followed by sleep mode and black screen)Ģ) then remove the power cable from the monitor (switching the monitor off using the button will NOT do it)Īnd actually this works for me: the monitor comes back up with a signal from the display port and I can set higher Hz and activate gsync in the Nvidia control panel!

I already tried the obvious (reboot, reset monitor to factory settings and then set the input to display part again, pull and check power cable, check display port cable on both ends).Īny suggestions on what more to try next? (The monitor works when connected via HDMI, but it is a high-Hz Gsync monitor and both features are only available when connected via DisplayPort, so running it via HDMI is completely pointless.) I have tried multiple HDMI 2.1 cables all official 2.1 48gb bandwidth.
