I am reading that the HT3050 has a lag of 49ms but that there might be a firmware update to decrease this. I am deciding between 2 BenQ models, but because I primarily play first person shooters online, it is a concern. Do you have an information on if the lag figure has changed.
The input lag has been improved to around 35ms. If you are using this primarily for gaming, you may want to look at the HT2150ST – it is made for gaming and has one of the lowest input lag times for projectors on the market at 19ms.
