Can work with ATSC-tuner for cable TV without QAM?

If your television has an ATSC tuner, but no QAM tuner, you'll be able to receive DTV over the air, but not from cable unless you have a cable tuner.

QAM is a cable form of ATSC, and you need a QAM tuner to receive digital TV on cable.

Yes, some Vizio, I think TVs, have ATSC tuner but not QAM.

You are correct, without a QAM you can't get cable channels without a cable set-top box.

ATSC tuners without QAM?

They're built together, always will be built together...You'll always be able to get the Standard package channels from Cable. It's when you want the PREMIUM channels that you want a box or CABLE-CARD® for it.....

Cable-Card® ready TV sets may sound nice, but those TVs STILL need the box. Cable-Card locks up more than the Motorola HD boxes do...

Their plan to make you only buy the CARD backfired on them.

So, get the box and don't worry about it....
