Just bought a new HDTV 120hz, lag on 1080i input...

post #1 of 7
Thread Starter 
So yeah, as the title said, I just bought an HDTV(Panasonic TC-L42E30) today and the HD terminal.
Here, with cable (videotron), the highest definition you can reach is 1080i (1080i vs 1080p)
But this input plugged on the 120hz TV, I see alot of image lagging like shown on 1080i vs 1080p.
Is there a way to fix this, to program the TV so it run at 60hz or even 30fps like the source.

Im not sure if it will reduce the lag I see.

But plugged on a PC or a bluray, the image is pretty good.

if at all possible just disable the Motion Picture Pro 4. If you still feel like youre getting lag - i do beleive the tv has a game mode available, simply turn that on. The settings should save to that video input only smile.gif

just a side note - even if you had a 120hz source, the tv can only accept a 60hz input.

So whats the point of getting a 120hz TV ?
The store seller told us that on sports channel, the image would run smoother because of the 120hz .

It refreshes at 120hz, it just cannot accept a 120Hz input from an external source.

Looking at the link you provided, there is infact a game mode, have you tried it? It claims to lessen lag.






Game Mode

Games are much more fun when there's no lag in operation. VIERA automatically chooses settings that provide the optimal image, so you get super-fast response and no delays. Even dark scenes with delicately rendered details are beautiful and easy

They're not really "120hz", they in a sense emulate 120hz by "processing" a 60hz input to make it look like a 120hz image. There is no true 120hz television commonly available to my knowledge. Some companies are moving away from even calling it "hertz" and calling it 120 or 240 dropping the "hertz" and sometimes adding their "motion flow" or "true motion" to it.

If you want a 120hz display as large as a big screen tv you'll have to pony as much money as a nice car.

If you're gaming and and plan to use a TV for your computer screen or for console use a 60hz LCD is all you need. Side note. "LED" televisions are still LCD televisions as they use the same screen, basically they just use an LCD panel with better color reproduction and use L.E.D.s (light emitting diodes) to light up the LCD panel versus the old conventional florescent lights. (I thought I would throw this in because a lot of people seem to think that these LED televisions have screens made of LEDs.)

Its mostly marketing hype with led tv. The only worthwhile led tvs are with full local array dimming and not the side lit one.

I think the lag the OP is experiencing is due to the cable source since its fine for bluray

Game mode is fine for fast-paced action like console games however when i turned that option on for regular viewing of tv shows,
the scenes felt like fast-forward x2. the actors where moving abnormally faster than intended...hard to explain but it was unpleasant for me
