Hi all, I need to buy a 32" or 37" LCD. I notice that all of the big name brands seem to be 720p at this size. If i'm watching a 1080i or 1080p source, will I notice the difference between a 720p or 1080p TV at this size?

Depends on how far you sit from it. But generally I would say you wouldn't really notice on a 32inch, but you most likely would with a 37inch.

Since 1/2 of the pixel detail has to be eliminated when downscaling 1080i or 1080p input to a 1280x720 720p display IMHO the sharpness will be less. If the 720p display is 1366x768 model(which many of them are) less detail will be eliminated. I reccomend 1080p models especially if playing 1080p Blu Ray disks

this TV will go in a small room. We are buying a treadmill and want to to put the TV on the wall in front of the treadmill. so we would likely be about 8 feet away from it. we would be watching either 1080i content from our cable TV provider via a digital box, or antenna. so would I see the differnce between a 720p TV versus a 1080p TV?

No....
Also consider that you are "working out", so critical viewing is not (or shouldn't be) that important.

There will always be a difference since 1080p is roughly double the resolution of 720p (about 2MP vs. about 1MP). The closer the set is to your viewing spot, the more noticeable the difference will be. If you are watching 1080i/p content regularly, a 1080p set is the way to go. If you mainly watching 720p content then it doesn't really matter either way.

Also, you have to ask yourself whether the 1080p will have a better overall picture (regardless of the higher resolution) as it will be a higher end set than an entry level 720p set. Stuff like color, contrast, blacks, viewing angles, etc. For example, the Samsung UN32EH5000 uses a better panel than the UN32EH4000 (Samsung panel versus AUO or CMO panel). (and the EH4000 is not available in 37" or higher, just 26" and 32")

Ultimately, you need to decide whether the higher resolution/better overall PQ will be worth the price difference or not for your viewing purpose. The difference is real/visible, the big question is whether you care enough to spend the extra amount or not. So, yes you'll notice the difference at this size but whether or not that difference is worth the price premium or not is for you to decide.

Agree with your technical points, but at 8' away and 32" to 37" set, it is probably not worth the extra expense for a 1080p set.
Color will be the same no matter the native resolution. Contrast, blacks and viewing angles aren't that great for any LCD TV, no matter the native resolution.

Edit:
Here are some links to "calculators" for an idea:

No matter what, in a 32" or 37" size and especially at 8' away, 720p is fine. Many networks broadcast in 720p anyway, and if you have cable it's always a toss up as to what resolution you are really seeing since they may down convert, compress and who knows what else with a digital signal. Also, there are some advantages to 720p if you care to search the net and this website for info on that.

And you can look at the many "recommended" charts, but go to a few stores, look at prospective TVs, see if you can get hold of the remote to tone down store modes, and then check thing like off angle viewing and how well you can see details in dark areas of images on the screen. Go with what your eyes tell you and then set a TV up at home with a calibration disc to make your own Media Assisted Settings. I have a 720p TV in out bedroom that, once set up properly is great and offers great picture quality and color rendition.

I get Comcast HD Cable and about 2/3 the HD channels are 1080i and the remaining 1/3 or so 720p. I can always tell the difference between a 720p channel and a 1080i one on a 1080p set, even a 32". Eight feet is pretty far back for such a small set, though.

When looking at the fans at a game I could see a little more detail on 1080 on a couple of tvs I had.almost looked like 720 turned detail into black or blur.although it is very very tiny difference between the 2.basically have to be right on front of tv to tell difference.I never tried turning brightness up a bit on 720 to see what that looked like.

I thought the motion looked tiny bit better on 1080i vs720 p(on the lk520 with trumotion settings turned up. Soe)).From what I remember that tv had the clearest motion I've seen on the few tvs I've had.

Each tv will give slightly different results and Show more detail depending on the brightness levels of it

ok thanks for all the replies guys. For the purposes of this TV and my wife saying she only wants to spend $200, I think i'm going to go with a 720p and a 32". she even said she'd want something smaller than a 32", but I want a 32". so lets say we get a 32". we want to mount it on the wall. our wall studs are only 16" apart. is this good enough? can someone recommend a good wall mounting bracket?

Have a look at the Cheetah wall mounts at Amazon. Compared to other brands, they're relatively cheap and still good enough to do the job.

I have my 65" LG (~100 lbs) mounted with one. I bolted a short length of 2x12 crosswise to the wall studs first with lags. Simply to get a little more clearance for reaching connections. But your 16" stud spacing will be fine.

Good luck.

The new Apple Tablet has what they call Retina Video processing which supplies a superb video screen at about 12-15 inches on it's 9.7 inch screen. One of the reasons for this is that it uses a much higher resolution then any chart will tell you is the maximum required for the screen size. The human mind apparently uses the pixels that provide the most contrast compared to adjacent pixels.
However, if you are a gamer then a 1280x720 720p display maybe the best for you since many games have a 720p native resolution and therfore would require no scaling the PC or the display which will therefore reduce display lag.

Four. And it should come with all the hardware you need; mine did. If it doesn't, I should think good quality hex head lag screws 1/4" or 5/16" in diameter and 2" to 2 1/2" long (plus one washer each) will do. Drill the pilot holes undersized so the lags have sufficient grip. But it's quite possible to drive them into pine studs without a pilot hole. Just takes the proper enclosed wrench and some elbow grease.

Good luck.

Heheh, wise guy. tongue.gif

How about this: you can do it with some extra effort. At any rate, you don't want the lags to back out, obviously. So you want 'em in there real tight.
