Issues Connecting PC and TV: Flickering and Sound Problems

Asked by Techie12345
I'm facing a frustrating issue with my setup. I have a powerful PC connected to a 27-inch 1440p 165Hz monitor which runs smoothly, capping games at 120Hz. Along with it, I have a 50-inch 4K 60Hz TV that's perfect for viewing from a distance. However, whenever both displays are connected and I use the monitor (screen 1), Windows keeps making that annoying startup soundโ€”even when the TV is turned off. On top of that, the monitor experiences strange flickering. I'm using Windows 11 and need help on how to configure both screens properly to avoid any flickering or stuttering. Any suggestions?

For your issue, ensure that your GPU drivers are up to date. Sometimes outdated drivers can cause connection problems between multiple displays. Also, check your cable connectionsโ€”loose cables can lead to flickering. If you have to use an adapter for the TV, try swapping it out if you can.

If you're using a splitter or an adapter, itโ€™s possible that it might not handle both displays well. You could also try changing the refresh rate for the TV to match the monitor and see if that reduces the flickering. Another tip is to set the monitor as your primary display in Windows to see if that stabilizes the connection.

To help you, I need a bit more info. What GPU do you have, like an RTX 3060 or RX 6700 XT? Also, how are your monitor and TV connected? Are they using DisplayPort or HDMI? Lastly, does just the monitor flicker, or do both screens go black when the sound happens?
