HDMI cable/port degrading? (self.techsupport)

submitted 11 months ago by CameronDev to c/[email protected]

7 comments fedilink hide all child comments

I have a moderately long HDMI cable running to a screen that has worked for quite a while. Recently the screen lost its connection. I replaced the cable with the exact same model of HDMI cable, and its all good. The cables arent frequently inserted or removed, and they are otherwise in good condition. I have no idea how or why this could happen. Any ideas?

Is your HDMI cable good quality? Is your tv good quality? Dissimilar metals on either will result in transfer of materials over time and degredation of their ability to transfer signal at the rates expected for HDMI. Normally just a reseat of the cable should fix this but extended use could result in permanent impairment of the interface.

They are default cables that came with Dell monitors. So, no idea quality wise. Reseating didnt help unfortunately.

Probably reasonable quality if they are dell supplied ones. Apologies, when you said they were long I thought they might have been some funny make with potentially questionable standards interpretation. If the cables aren't moving around, under tension or being squished/crushed they should be one of the last things to fail, and a reseat should fix most issues.
