Is it true that 100hz tv gives you a much clearer and sharper picture than 50hz.?

Answer 1

50hz = 50 cycle (images) a second

100hz = 100 cycles a second

it looks a little bit more stable bot you do get a clearer ceefax service...if that helps...note the sarcasm

samsung do a HD ready CRT that does away with 50 and 100Hz crap.

Answer 2

Yes and no.

It will NOT give you a sharper picture. It will NOT give you a clearer picture. Only a high quality tube (which most 100Hz systems will have by default) can do this.

But it WILL give you a more stable image for your brain to process. The higher refresh rate of the screen reduces VISIBLE flicker making the image appear more 'solid' and less jittery.

TV pictures (UK) are transmitted at 25 frames per second. In a normal CRT TV, the same image is scanned TWICE, in a 100Hz machine - FOUR times.

Answer 3

Not clearer or sharper, but less flicker. Although you can't see the flicker directly, it's there and you see it sub-conciously 'cause it's too fast for your eyes to make out. It's caused by the picture refresh 'beating' with the 50Hz flicker caused by electric lights, fluorescent tubes etc. 100 Hz refresh rate still beats with the lights, but the beat frequency is faster so you see it even less.

Answer 4

yes you get 100 pictures a sec with 100hz, 50 per sec with 50hz

Answer 5

Sort of. Basically, you'll think it will. Although you don't see the picture flickering, you're subconsciously aware of it. With 100hz, it changes twice as fast, and is thus harder to see. So the picture looks more stable and cleaner. Don't spend heaps more for it, but it's a worthy feature

Answer 6

Yes

Answer 7

Yes, a higher refresh rate means better quality.

Answer 8

Yes, but not all broadcasts/devices will support the higher refresh rate.

Answer 9

YES
