Just read through the CNET review and this "As LG's entry-level line of 1080p resolution LCDs, the LH30's big missing feature compared with the step-up LH40 models is 120Hz with dejudder processing" makes me believe it is 60Hz.
And this "Cons: It is only 60Hz refresh, but most movies are shot at 30HZ, so it doesn't matter unless you watch extreme sports or play intense video games" from a Newegg review confirms it.
