In Device Manager, the Exclamation Mark now appears again for the Cable Matters USB-C Video Cable under Universal Serial bus devices. Additionally, after unplugging the cable from the Sabrent port hub, I noticed a noticeable mark on the back of the adapter. When I smelled it, it had a burning odor, suggesting it had been fried. This smell is unusual and doesn’t match the normal scent of the cable. I’m uncertain whether this indicates typical usage wear or a recent overheating issue. It seems unlikely that a blue Ethernet cable would develop such a smell. Regarding the HDMI cables, I suspect the one used for the 32' 4K Samsung monitor may have been damaged. When I ejected it from the Sabrent port, it didn’t appear in the correct tray, and connecting an HDMI cable to the HDMI port on my XPS laptop showed no signal. Switching to a different Chromebook worked, but the monitor still displayed properly. This suggests the issue might be specific to that device.
My options now are unclear. Could I purchase an HDMI adapter to connect to my XPS laptop temporarily? I currently rely on two external monitors and can’t use the Asus monitor due to a damaged HDMI port. Replacing the motherboard seems necessary if the problem persists, but it could lead to further complications. Using the laptop as-is might pose risks, especially if the HDMI port is damaged.
I’m seeking advice on whether it’s safe to continue using this laptop—whether as the main machine or a spare—and whether buying an HDMI adapter would be a viable solution.
I likely won’t need that hub anymore. What part of the cable matters? Here’s a link if you want more info. Your laptop model is unclear, so I can only suggest based on guesses. The monitor seems to work fine. If it’s an HDMI port, you could connect a USB to HDMI using your existing USB ports. I don’t know your exact laptop, so I’m just making educated guesses. Repairing it probably costs more than replacing the whole machine, depending on how much you spent. Yes, people can fix it. I haven’t seen anything fail from a lightning strike, but many have. I use surge protectors, though they seem to wear out each time and stop working.
The cable matters is an adapter for connecting via ethernet to a laptop. It resembles this product from cablematters. I’d likely need something similar priced near $150. Should I connect it to a Sabrent hub or a USB port on the laptop? The Sabrent hub still functions, and the keyboard plugged in works too. A USB flash drive also fits. My challenge is getting HDMI on my laptop for dual monitors. I’m using a 32" 4K Samsung monitor via USB-C to displayport. For the Asus monitor, HDMI connection isn’t working because the port isn’t compatible. What alternatives exist besides replacing the laptop?
