Q. Hello everyone!
I just have a question about my tv. I have a Vizio HDTV I bought just in February. (The e261va to be exact.) and I mostly play my Xbox 360 on it through an hdmi cable. It's only 720p, Don't get me wrong, the picture is perfect! It has incrediable color and contrast and everything runs smoothly.
but there is just one thing bothering me. When I look through my iPhones camera at the tv there are vertical lines going through it. With all my other hd Tvs this doesn't happen. I was just wondering if this is showing signs of wear, or am i just being nitpicky or just something that happens with this TV. Any info will be greatly appreciated!

A. LED backlit/edgelit LCD TVs dim the backlight brightness using PWM, which is pulse width modulation, that is the LEDs are actually flashing full on and off faster than you can see.
This has 2 benefits:
1. The flashing helps mask the natural LCD blur or smearing.
2. This method of dimming LEDs (full current then no current) is more energy efficient than dimming them via a constant reduced current.

Would an LED or LCD HDTV be better?
Q. For gaming and blue ray.
A. First, unless it is an OLED, "LED" and LCD are the same thing. They both have LCD panels, the ones called just LCD have cold cathode fluorescent lamps for the backlight, LED obviously uses LEDs for the backlight.
And there is no "E" in Blu-ray Disc, which is the proper spelling and capitalization.
What is more important is the panel type, like TN, VA, or IPS. A spec they usually don't specify. A VA or IPS panel with fluorescent backlight is better than a TN with LED backlight. that said my Vizio M260MV is an LED edge type backlit TN 1080p LCD and I love it for Blu-ray and gaming. I typed this on it as my computer monitor.
