Response Time Concerns

04-19-2010, 05:47 PM
I'm looking to purchase a new HDTV, and was hoping for a little bit of expertise concerning how important response times & refresh rate effect images. I'm interested in a 37" (I've lurked a bit and noticed some exclaiming to go bigger, but I've looked at a couple at a retailer and anything bigger than 37" would seem to overpower my small room). I'm in a dorm, sit 8' from my TV, low lighting conditions, replacing a CRT 32". Will mostly use to watch sports & play Ps3. Looking to go used/refurb because of budget limitations. I've come across 3 HDTV's that seem to fit my admittedly narrow profile. The Samsung LN37B530, the Panasonic Viera TC-L37S1, and the Vizio SV370XVT. I can get them all shipped at or just under $540 (from B&H or Tiger Direct). Both the Panasonic & Samsung are 60hz, and the Vizio is 120hz refresh rate. The Panasonic is the lowest response time at 8ms but they claim some sort of wizardry with a motion focus technology to increase to 120 fps. At 60hz the Samsung is 6ms. And for all the clamoring of 120hz the Vizio is only 1ms faster at 5ms response time. All are 1080p. I know these are last years models and some of you might wag your finger, but as I said my budget is limited to under $550 shipped. Also the plasmas are just too big, can't seem to find one under 42" so please avoid that tangent. Thanks for any help you might be able to offer.

Refresh rate and response time are two different things. And there is no standard for measuring response time so the specs on the separate tv's make no difference. LCD's are slow and have motion blur. Its a limitation of the technology.

In your case i would go with either the Panny or Sammy as Vizio is a tier below them still.

I have a 50" at 8' distance and want to move to a 54-58" size next.

Santa is correct that the mfg measure them differently and there is no standardized test for some reason so you cannot compare rated speeds between different mfg. Heck some mfg change the way they measure between model years as well. It is kind of like how inkjet printers are rated for 30 pages/minute yet you can never get that speed in realy life. The spec is almost meaningless just like contrast ratios when comparing different mfg models.

If $540 is in your price range, I just picked up the Samsung PN42C450 from best buy for that exact price.

This is a 42" plasma display. I also sit about 8' from my screen and I like my screen size, but could certainly go bigger, so 42" shouldn't overpower your room (they're only 4" thick lol).

Also, if you are concerned about response times, plasma response times are .001ms as opposed to the fastest LCDs at 2ms.

The display is only 720p, but the human eye won't discern the benefits of 1080p at that size and distance. Plasmas also utilize 600Hz sub-field drive. Basically it is a 60Hz refresh rate, but is produced over 10 sub-fields hence the 600Hz.

Refresh rate and response time are ways to measure the display's performance with fast-moving images. It is clear that plasma is superior in both fields. If you are looking to play FPS games or any game for that matter, you can't go wrong with a new plasma.

Find someone with a pickup, have them drive you to BB, and check out a plasma! They might not look best in those bright stores, but the poorly lit dorm room will make plasma shine!

Oh, I didn't know that there weren't standardized ways to measure response time. I'll look into that plasma, since you pegged me right w/ the FPS comment. I play a lot of modern warfare 2. I thought for sure I'd need 1080p, but if one can't really tell the difference i'd be interested, since I even noticed a prompt on my mlb the show 10 that says they basically made the game to run at 720p. Anyway, thanks for your help, if the plasma again seems too large in person i'll go with the Panasonic.
