I was close to buying a TV today but for some reason I was put off when I was told its 50hz.

I then started to look at 100hz TVs, most of which are LED and the price jumps up from 50hz being around £400 to £600+ all because of the hz.

Im no expert but am I right in saying that this is simply the frame rate? I am more used to taking FPS from PC gaming and im putting this as a similarity.
I am using a Samsung 26" HD Ready TV thats about 5 years old now and the picture on the PS3 is great imo... this TV MUST be 50hz.

If I go out tomorrow and buy the LG 37" Full HD TV with built in HD Free-view am I going to be disappointed and notice that its only 50hz? Is it really worth the extra money to go up to 100hz?

100Hz basically just means the TV does some video processing to make up frames and display them inbetween the normal frames.

I personally don't get on with the effect but you might like it - go in and have a look at them in person and ask for a demo of the 100Hz mode.
 
Ive just brought a Phillips 100Hz LCD and love the picture on it but as Phil99 said above go and check them out as even the sales rep at Richer sounds said a few people cant get on with them.
 
I can't get on with 100Hz - always notice the image processing when it can't correctly predict the inbetween frame.

There's nothing wrong with 50Hz on LCD panels. It's not like they suffer from flicker (like large 50Hz CRTs did). 100Hz IMO is just a product marketing to increase showroom appeal.
 
Digital TV in the UK is 50hz. All these TVs do is receive that 50hz signal and artificially increase the frame rate of the video by guessing frames, making motion seem "smoother". Personally I find the effect artificial and uncinematic, as such I always turn it off. I'd be more concerned about whether the TV can accept and display a true 24hz signal from Blu-Rays :).

Dixons might be a competitor, hard to tell sometimes.

I have the LG 32LD490, which I strongly suspect is the 32" version of the one you're looking at. The best feature imo is the ethernet port. Your link says it's for a modem, richer sounds told me it lets you connect to iplayer but nothing else. In practice it'll play media streamed over the network from a media server. I've installed "mediatomb" on a computer, and consequently can play any videos saved to the computer's hard drive through the TV, using the standard remote control.

As far as I'm concerned, that's amazing. Very happy with the new TV, so I'm confident you'll like your new (bigger :) ) one too.
 
Match the TV to the highest input refresh rate it's likely to see.

It's been tested repeatedly and most (not all) people can't differentiate at all above around 60FPS. We can tell the difference between 24 and 60, but that's about it. I'd rather see the input as it was transmitted, rather than messing about with post-processing, myself. It's worth having a look for yourself, but to me it's mostly/entirely a gimmick.
 
Useful to know that digital TV in the UK is 50hz.....would I notice a difference if I was watching a blue ray movie on my ps3 via hdmi?

UK broadcasts are 25fps. The source signal is interlaced (ie odd lines sent on one cycle, even lines on the next) which doubles it to give the 50Hz.

Movies at the cinema are 24fps as are most Blu-Ray discs. Recent Blu-Ray players including the PS3 will output the source 24fps or convert to the more usual 50/60Hz via HDMI.

If I was buying at the moment I'd be ignoring 100Hz and looking for proper 24fps support instead.

Unfortunately my 32" Panasonic is is from the range before true 24fps was supported. You can see it jerk occasionally on long panning shots which I find distracting.
 
I did some research a while ago when the lads at work were boasting about 600Hz TV`s.

Virgin HD is 50Hz
Sky plus HD 50Hz
PS3 60Hz.
Freeview 50Hz.
 
if your watching footy 100hz all the way .. i was in a pub where 2 tvs side by side ... omg it was judder central on one of them .. watching the ball move made me ill

Was that the 100Hz, or just the TVs? There are plenty of other factors which can come into it.

I'd rather have a refresh rate which precisely matches the source rate. 100Hz won't do any damage, but it just means it's showing the same thing twice each time... pointless.

They can have some interpolation, but I don't like my equipment second guessing what's going to happen - it can try to predict the connecting frame, get it wrong and show something it's just made up mathematically.

Your over simplfying it.

The price doesnt go up just because of the 100hz processing.

The manufacturers have a range of TVs in the range, each progressively more expensive than the other. On the cheapest model, they will take out things like the 100hz processing tech to keep the costs down. But they will often remove other things as well that are present on the top end model.

The more expensive TVs will have 100hz processing, but they usually have better IQ and more features too.

as said already, bluray is 24fps. If you want to enjoy the film at its best then turn off 100hz processing for your PS3 input as it messes with the film and how the director intended it to be shown. It can sometimes over compensate and speed up sections that are supposed to be slower etc..
 
I watched the Avatar Blu Ray on a TV that was 200Hz in the showroom. It looked so much more real as it was so smooth. I didn't notice anything untoward, but I probably wasn't watching long enough. I then played Avatar Blu Ray on my own TV (using 24Hz) and it just didn't feel as real to me (though still looked good!).
 
I saw it in 3D at the cinema - nothing quite like that! 3D was hard work to watch, felt like I had to predict where the camera would focus, rather than being free to do it myself. Can't really remember how fluid it was.

I just really feel the difference between refresh rates I think. Even on monitors- when there's movement the difference is always pronounced to me.
