Bonus tipДЄs I mentioned above, the вЂњpвЂќ in вЂњ1080pвЂќ stands for вЂњprogressiveвЂќ-meaning a TV screen thatвЂ™s capable of drawing a complete frame in a single pass, resulting in a smooth, solid image. Want a screen thatвЂ™s 42 inches or bigger? Go ahead and spring for 1080p. My recommendation: If youвЂ™re shopping for an HDTV set with a screen thatвЂ™s 40 inches or smaller, 720p should do the trick.

So, does that mean a 1080p HDTV will look twice as sharp as a 720p HD set? Not necessarily.ДЄs with the whole Hz issue, thereвЂ™s a point of diminishing returns when it comes to resolution-and as IвЂ™ve written in an earlier post, many TV experts agree that on a 40-inch or smaller HDTV, the human eye canвЂ™t tell the difference between 1080p and 720p. Meanwhile, a 720p display boasts 1,280 by 720 pixels, for a total of about 920,000 pixels-about half as many as on a 1080p display. (Incidentally, the вЂњpвЂќ in вЂњ1080pвЂќ stands for вЂњprogressive,вЂќ not вЂњpixels.вЂќ Check out the Bonus Tip below for more details.)ДЄ 1080p HDTV, for example, has 1,080 horizontal lines of resolution, with each line containing 1,920 pixels from one end to the other, for a grand total of more than 2 million pixels. While Hz refers to the refresh rate of your HDTVвЂ™s screen, the вЂњpвЂќ number tells you the actual resolution of your TVвЂ™s display-in other words, how many rows of вЂњpixelsвЂќ are packed into your HDTVвЂ™s display panel. OK, so whatвЂ™s the difference between Hz (as in 120Hz) and вЂњpвЂќ (as in 1080p)? If a blue-shirted sales clerk tries to upsell you to 240Hz, donвЂ™t take the bait.

Home video experts call the too-smooth picture generated by features like MotionFlow and Motion Plus the вЂњsoap operaвЂќ effect, with good reason.Д«ottom line? An HDTV with a refresh rate of 60Hz or 120Hz will probably look perfectly fine to your eyes. Personally, I find it unnatural and somewhat unnerving, particularly when it comes to movies (which are typically still shot and displayed at just 24 frames per second). Some viewers love the way movies and TV shows look with, say, SonyвЂ™s MotionFlow feature turned on. YouвЂ™ll also see HDTVs with cool-sounding features like вЂњMotionFlowвЂќ (from Sony) and вЂњMotion PlusвЂќ (on Samsung sets) that use their high refresh rates to artificially smooth the picture on your TV screen, resulting in images that glide across the screen with nary a judder. In other words, thereвЂ™s a point of diminishing returns once you hit a refresh rate of about 60Hz or so. Indeed, even the experts have a hard time telling the difference between a 240Hz HDTV and a 120Hz model-or even between a 120Hz set and one with just a 60Hz refresh rate. About five or six years ago, TV makers began crowing about the ultra-smooth picture of 120Hz sets nowadays, refresh rates of 240Hz and up are all the rage.Д«ut hereвЂ™s the thing: An HDTV with a refresh rate of 240Hz doesnвЂ™t necessarily look twice as good as a set with a 120Hz refresh rate. Generally speaking, the faster your TVвЂ™s refresh rate, the smoother and less blurry the picture.Д«ack in the day, an HDTV with a refresh rate of 60Hz (or 60 refreshes a second) was considered pretty good. LetвЂ™s start with вЂњHz,вЂќ which refers to the вЂњrefreshвЂќ rate of your TV-that is, how many times per second it can refresh the image on the screen. вЂњpвЂќ issue-and as youвЂ™ll soon see, you donвЂ™t need to pick one over the other. Well, donвЂ™t worry I can help clear up the whole вЂњHzвЂќ vs. Hi Shelly! Yep, I hear you: all the numbers and abbreviations that TV manufacturers throw at you can be pretty confusing-not to mention all the features that you supposedly вЂњmustвЂќ have on your new HDTV.
