When Google unveiled a wider range of TVs with Google Cast support, you might have done a double-take when you saw Polaroid's name -- what, the reborn camera maker? Yes, it's true... and you may have a good reason to take notice. Polaroid has unveiled its first-ever smart TVs, and it's clear that they offer some bang for the buck. Every model in the LED-lit range packs a 4K display, a 120Hz refresh rate, native HEVC decoding and Google Cast streaming, so you won't have trouble either watching Ultra HD video or sharing a YouTube clip from your phone.
