1080p 60Hz - or - 720p 600Hz ? Main differences? Which is better? Help!

Crew 569 434 December 1, 2010 at 09:22 AM
Well, I'm looking to upgrade my 32" Olevia LCD. It's great, but it's time for a change..

I'm looking for a 37-40" TV, but that's as far as I've gotten. It will be used primarily for PS3 and blu-ray movies, but I definitely want to watch sports and some TV shows as well.

Now, the question remains, which will give me a better viewing experience ? The TV is about 10' from my bed and couch. How will 1080p with a low refresh rate differ from 720p/1080i with a much higher refresh rate ? I'll be playing call of duty, etc.. watching action movies, and just want to get the best TV I can.

Thank you all!!

Matt

watch those refresh rates - they're like threadcounts on bedsheets - it all depends HOW you count "Hz"

FYI: the 600Hz screen is going to be a plasma TV, not LCD.

LCDs come in 60Hz, 120, 240 (and, for some reason, now in 480 too). But something in your price range is 60 or 120.

In my experience, Plasmas are great for dark rooms, but if your livingroom has a lot of light coming in from windows and such (and you watch/play during the day a lot), the glossy screen on most plasmas can be annoying (and an LCD might be preferred). There are dozens of other differences between the two as well.

Also, here's an engadget article [engadget.com] that gives a rough outline of viewing distance vs screen size - will you notice the difference between 720p and 1080p

I don't understand the appeal of super refresh rates. TV content maxes out at 60fps (60Hz), and films max out at 24fps. 120Hz is better than 60Hz for film, since 120 is a nice neat integer multiple of 24, while 60 isn't. But 240Hz? 480Hz? What's the point?

Yeah, I think anything beyond 120 is just a waste of money. Some people even argue that 120 isn't worth the extra cost over 60Hz.

Plasma is a different story because 600 is the standard for that technology (and there aren't any other options).

to the public, the "more" or "greater" anything is, it's automatically better. so, 480>240>120>60, naturally. Now, whether anything is really gained by the higher refresh rate, or if it's a REAL refresh rate and not some cooked up number, is a different story.

The reason I brought up the threadcount analogy is that GENERALLY, the higher the threadcount of a sheet, the smoother it will feel. There is a limit past which you won't tell the difference, but many skeavy retailers sell, say, "600" threadcount sheets that aren't comparable to TRUE 600 threadcount sheets, and while accurate it's misleading. The same goes with refresh rates. Can you tell the difference between 480 and 240? Hell, most people can't even see the difference between 60 and 80(?) on a conventional CRT.

True, I should have made note that the 600Hz was a plasma, and the 60Hz is not specified, just a generalization.

Most (if not all) of my viewing would be done in the evenings. I work all day starting early and don't start watching or whatever until after dark. How about an overhead, three-spoke, below-fan, type of light ? Chances are one of the bulbs will be pointed towards the screen, but it's not a spotlight and it's not at an angle where it will reflect towards my field of view.

True. F*ck you, Hotel Luxury Linens! Big Grin

But yeah, I get what you mean. Basically, the one I'm looking at is the LG "42PJ350". It lists: "600Hz Sub Field Driving" and 3 million to 1 contrast ratio.

Any thoughts on how to tell if the refresh rate is anywhere close to advertised? Where would it be most prevalent? Movies, games, TV sports?

Thanks all! Keep the comments coming!

A 60Hz (600Hz) Plasma will be able to display smoother motion and better colors than any xxx Hz LCD.

If picture quality is important to you, get the plasma. The pixel response time is almost instantaneous vs LCD's refresh rate of ~5ms.

I have 42PJ350, 50PJ350 both 720P and a 50PK550 1080P LG plasma. They all look and perform the same. GREAT.

Blu-ray will play at 24Hz as intended. Sports action is smooth. Colors are unbelievable. No input lag while gaming. You can't go wrong Big Grin

These refresh technologies are all methods to prevent flicker and smearing in the panel. In a film, for example, the rate is 24 frames/sec, but film projectors open and close a shutter which makes an effective refresh rate of 48 fps. Without this, flicker would be so bad that you'd walk out of the theater.

LCD and plasma screens are different, and you can't compare the refresh rate of one to the other. For gaming, I would choose a 1080p LCD over a 720p plasma, but for movies, the plasma may be better. There is huge variance in screen quality, though, so you can't simply compare a few numbers and get a meaningful result.
