Yes, this is it, but it's not a thunderbolt port of mine, I connect it with a type-C to dp1.4 cable it did work, would work just fine with my Y740-2070max-Q, so I guess the port is not a thunderbolt port at all, also same things have been mention in Amazon reviews in the same list.

Where did you get your unit from? I see Newegg is selling the same laptop but mention it has a thunderbolt 4. but Amazon
didn't mention it, I guess maybe there are two types of units out there, I don't know.
My laptop just can't wake up with the external monitor, it's like
one-third chance that when it wakes up from sleep, it shows blank in the external monitor. Reboot the computer will occur even more often. It's really annoying to me.
Did you test the thunderbolt 4 slot, if it works out, it should be like a dp1.4 port, can output a 4k@120hz external monitor. Since my Y740-2070max-Q was bought two years ago, but I
didn't use the thunderbolt 3 slot at all, I think it wouldn't affect my daily use of the laptop.
But that sticker is really a liar. Such tricks even the manufacturers from mainland China won't use nowadays, how come we see it in a Taiwan gigabyte laptop which is selling on Amazon. This is really unacceptable.
