Great, it looks like you enabled GEN3 operation for this card.

If the PCIE link was broken, the card would randomly be able to get
enabled, so I find it unlikely that it's firmware / board issue. My
colleague (CC'ed), succeeded to enable Nvidia GT710 with debian daily
(based on v4.14):

Can you try it?

He's not complaining about speckling  whatsoever. However he's using
vga cable. Can you check one? And recheck your hdmi connection as
well?

Best regards,
Marcin
