The internet stops working after connecting a second monitor.
The internet stops working after connecting a second monitor.
I wasn't sure if posting here should be in the main forum or the displays section. My internet on my PC either stops working completely or becomes very slow when I connect the second screen. My main display is a 1440x2560 144hz model, using a DisplayPort cable, while my second monitor is a 1080p unit with an HDMI connection. These have functioned smoothly for at least two months after I upgraded to the 1440p model. It seems to work only for about two days now. The first screen won't connect properly, and Discord stops working too, reporting it can't find the web server. Luckily, I managed to test with the first screen connected.
It's connected via Wi-Fi, but only activates when used with my PC. Connecting my Xbox to a second monitor triggers it; it doesn't when using HDMI on the PC. It functioned perfectly before. I plan to purchase LAN cables soon, which could resolve this issue.
Is there another way to connect the monitor to your PC besides HDMI? HDMI can handle video and Ethernet, so a faulty or damaged cable might be the problem. This seems like an unusual issue, but I’d try a different connection method first—DisplayPort would likely work best.
If your screen caused so much interference via EMI, you’d notice your internet speed dropping. Plus, you’d be in danger.
Access Point signals create clashes since they operate on identical frequencies. Microwaves function at 2.4GHz, which overlaps with other wireless bands like 5GHz. If a display device lacks radio capability and can't emit waves (beyond visible light), the issue likely points to a more serious problem.
