Question

Samsung

My 4k TV blinks randomly for a few seconds while connected to my laptop via HDMI. Is my cable not strong enough to handle the bandwidth? I bought an UHD cable that claims its made for 4k tv.

Re: 4k

- Is the laptop sending a 4K signal also? Or must the TV do upscaling?
- How long is the cable?
- Did you try another (shorter, same quality) cable?
- What TV exactly?
- Does it happen also with another hdmi device sending an image in the same resolution as the laptop (say, your phone, tablet, cable box or bluray player?).
- Any friend with another 4K TV to try?

Answer
Research "HDMI BLINKS"

It's a common issue not limited to Samsung. It's rarely if ever a cable issue. Don't be shy to return the set if seller and maker don't resolve it.
