I am about to purchase a new TV and I am considering a 100Hz model. I have heard that these TVs have problems with fast moving digital pictures eg football. Most of my viewing is done through digital cable and football ranks high on the list.

Could any 100Hz users share their views?

i dont own one, but basically a case of what your eyes like - i can tell difference between 60hz and 70hz - cause im used to sitting at a monitor.
so my eyes can like 100hz...

panning camaras look great to me, as well as jumps and rubbles of the camera...
but that was on a dvd player with 96hz output...
so as far as i know, your gonna have problems as the tv is refresing faster than the digibox, but u wont be able to tell - as 100hz is above normal eyesights refresh rate neway - aparently...

so basically this message doesent help u at all... but tis what i think u will see..

I have a 100hz set - the plus is that it is flicker free - the human eye, I believe, although will stand corrected, notices flicker at less than @70-80hz.

Downside, I think, is that they are more susceptable to digital artefacts, ie blocking - not usually noticable, but can be when a lot of the screen is the same colour - eg night time, or the green of a football pitch.

Depending on personal prefs, some prefer the 50hz, some the 100hz - me - I'm perfectly happy, but best bet is to have a look at 2 sets next to each other in a store and see what you think.

we were always told at work that 100hz sets were better than conventional 50hz then the boss went to a sony convention and was told he was wrong it's plain to see that if you don't have a crystal clear terrestrial picture it actulally makes it worse - tends to blur the image - if you watch say sky on a scart it still isn't 100%clear . you stand a 50hz sony next to a 100hz sony (to get the same tube quality) the picture is a way better on the 50hz

From the very limited experience I've seen of these TVs, 100Hz tends to look LOTS better with film-sourced material, whereas 50Hz looks better with your "live" sporty type things.

But my experience is very very limited, just seen them a couple of times in action....

100Hz looks great if it has a very good quality source i.e. DVD, digital cable, digital sat etc. I only occasionally get the digital problems that are always mentioned and I am not convinced that is the TV, I suspect that digital cable is the cause of some of those problems as I never get that with a DVD source.

However, 100Hz can show up the problems with a poor quality source more than a 50Hz set.

Take a look at both and decide what you prefer or find one with switchable 50/100Hz options. Panasonics certainly used to have that, not sure about other. My Tosh is fixed 100Hz, but I am very happy with it.

I have a 100Hz telly. Yes, flicker free, and it makes you go "ugh" when you see a 50Hz telly.

I don't know what blocking means, but I've noticed that horizontally scrolling credits cause a blurred vision. Are other users having the same effects, or is it just my telly?

Whenever credits are scrolled from right to left (like at the bottom of the screen at the end of a programme), it is very difficult to read them - whether they are from an analogue or digital signal. Probably made worse by the fact the picture may be stretched for widescreen broadcasts (although 4:3 broadcasts are still difficult to read).

That's the one!
Is it a 100Hz problem? Why does it do that - it's just 2x50! It's very annoying. I've noticed it sometimes depends on what is behind the credits.

I've got a Philips 36" Widescreen (36PW9525) set which has 100Hz scanning. In order to eliminate the mentioned artifacts the set employs a Digital Scan and Natural Motion devices.

These ensure that majority of normal television looks great, we've watched the odd footy match and everything looks great (Sky Sports Widescreen).

However, when credits etc roll accross the screen they can become unreadable, not always but 70% of the time. This seems to occur mostly when credits run accross rather then up/down. (i.e. most apparent on Financial channels).

However, this is very minimum and don't let it put you off. I honestly can't watch my normal television in the other room anymore, the flicker is far, far to great.

a 100Hz picture is very, very stable on screen.

What is it with this - I cannot watch normal t.v. anymore? Do people convince themselves this is the case or is it really true? I recently sat in my local Euronics centre for approx 30 minutes watching a Sony 50Hz and a Sony 100Hz side by side. Couldn't see one jot of difference and certainly couldn't detect any sign of a flicker. The pain was no longer present in my cheque book arm and I left the shop empty handed. I will carry on watching my trusty 17year old Sony t.v. until one day (perhaps) it might eventually go to that great CRT graveyard in the sky. Who knows, by then widescreen t.v.'s might actually be shipped without faults and perform as well as my old telly.

I have a 100Hz tv with the option of going 60Hz - I always choose 100Hz. I have to agree with opthers - if you're interested in credits, horizontal scrolling you cannot see it's just a blur but otherwise it's much smoother. i also find now that if i do turn it to 60hz i cannot stand the flickering which i didn't notice until I got 100hz.

When i bought the tv I didn't know it was 100hz or what that meant, but glad i've got it now, but wouldn't pay out especially for it.

What make and model have you got?, sounds a good idea to have both 60&100hz, do many models have this option?

It's a Hitachi I've got, but don't know model - it says progressive scan on the front - don't know if that's what it's also called. When I bought it I didn't know about the option of 60hz so maybe just ask - probably more have the option than you think.

After reading this strand I discovered my Panny TX32PF10 is 50/100hz switchable. The flicker difference is noticeable between settings. Can't comment on other makes tho.

This is good new's as i was not going to get a 100hz TV as i thought it'd cause me to many problems, mainly because i have a PS2 and most games do not have a 100hz option on them, great

As I understand it, its because a 100Hz TV is displaying twice as many fields as are transmitted, so it has to guess at the ones in between. Normally this is okay because it just looks at the previous field and the next field, and works out what would be reasonable to put between them. When there are scrolling credits (or any other horizontally scolling objects with vertical edges) the picture in that area changes from the background picture in one field to the foreground text in the next. When the TV tries to guess at the in-between field in those areas, then its faced with two completely different before and after fields. The problem is that the decision it makes will be different every time, and for different parts of the scrolling text, hence the blurry, jittery mess!

Some TVs try to be really clever by using all sorts of predictive algorithms, but with limited success.

Why don't 100Hz TVs include a mode to just show the same frame twice, rather than trying to be clever and interpolate? It must be pretty much impossible to accurately interpolate between two frames of a fast-moving picture; I'd have thought in many cases just doubling the frame would be preferable.

Many TV's do have a feature which allows certain 100Hz modes to be turned on/off as needed. Most top model 36" widescreen's for example for various options, my Philips has Natural Motion & Digital Scan options as well as the 100Hz option.

It doesn't matter about the games or the device attached, the television makes up the 100Hz field...

Hi Pyara

Just a matter of interest, how does a 100 Hz tv affect PS2 games? Do they not play at all? We have just got a 50 Hz widescreen in October followed by the PS2 for Christmas. So I am wondering if we made a even better choice going for the 50 as opposed to the 100 Hz tv if the PS2 would have been affected.

Many thanks.

An earlier person wrote that his PS2 was not a 100Hz version, I was merely pointing out it doesn't matter what device you connect to a 100Hz television, the output picture will always be a 100Hz, hence you will benefit from any input source...

Yes I understand the point you are making, it is what I believed to be true. However, I misunderstood your last post, apologies. I know the PS2 has problems with 100 Hz tvs when you try to use g cons with them, this is probably to do with the refresh rate. It was just after reading a post by Bryan I wondered if there were any other problems associated with 100 Hz.

Sorry wicket and Pyara if i clouded the waters a bit, i didn't realise the problem was just with g-con's but thank's to you both for making that clearer for me too.
As you've probably noticed my technical knowledge is not to good and i only really learn anything tekkie from these boards, just aswell they're here or i'd still be using candles and writing with a feather
