Wrong HDMI cable?

Hi

I am connecting my computer win10 to my Denon AVRX1500H .

I have used a cable tester to test my first cable and the tester shows that not all the pins are connected.

Bad cable?

My second cable test ok.

Good cable

No my connection works with second cable but not first.

Have I purchased a different type of HDMI cable?

Thanks

Richard
