Apparently the response time is 2ms.
Response time is inadvertently confused with input lag. It actually refers to the amount of time it takes a pixel in an LCD monitor takes to go from one black to white and back to black again. Higher response time means more noticeable ghosting. Higher input lag, on the other hand, means a greater delay in your controller, keyboard or mouse input.
Moving on to your question:
- Should you buy a 3DTV?
- Yes, you should, especially if you're a movie buff or have a PC capable of doing 3D at playable frame rates. Wouldn't recommend it with the PS3, since enabling 3D more often than not results in downgraded visuals (lower resolution, frame rate - that kinda stuff).
- Should you buy a Samsung 3DTV?
- No! Every single Samsung 3DTV out there suffers from tons of input lag. The 3D effect itself also suffers from a lot of crosstalk, dithering, and an unusual color tint. Though, admittedly, the crosstalk issue is there in pretty much every 3DTV out there, it's less significant in some Sony LEDs and Panasonic Plasmas.
- What 3DTV suffers from the least input lag?
- The best thing to do at this point would be to wait for the
Sony EX 720 to arrive in Pakistan. Suffers from around 21ms of maximum input lag, which is really good when you consider the lag on the other 3DTVs out there.
It's already out in Europe and the Middle East, and it's only a matter of time before these panels arrive in the local markets here.
