Vizio SV420M Review: 42” LCD HDTV
Up for Review: Vizio SV420M LCD TV. This is indeed a good-looking product from Vizio. It is a slim black bezel with the Vizio name inscribed at the bottom of the set. A review suggests that the Vizio SV420M has 1080p resolution. This will allow for excellent picture quality and sharp pictures. The images will seem to be very natural. To add tom it is the 120Hz SmoothMotion technology which will display the images without any judder. The images will be very smooth and crisp.
The Vizio SV420M has 50,000:1 contrast ratio which means sharp pictures and greater black levels. The black levels portray the blackest of colors and in doing so bring out the natural clarity of the images. This efficient contrast ratio does not interfere with the low power consumption. This HDTV sports energy levels much lower than the specified Energy Star ratings. You can safely save a few dollars here. This also has a healthy impact on our environment.

With the SRS TruSurround HD™, the audio is just outstanding. The bass performance is very good and so is the clarity of dialogues. You can hear what your favorite stars are saying with distinct clarity. The Vizio SV420M also has SRS TruVolume which controls the variations in the sound levels. The advertisements will not sound too loud or there will not be a sudden rise of sound level while changing channels. This is very annoying to the ears and Vizio has done a good job by improving it.
There are 8 times more high definition inputs which also includes 4 HDMI connections. This is quite a number of inputs which will make your Vizio SV420M the most “connected”. There is also an integrated tuner which will grasp the incoming free signals from the air. The 178 degree viewing angle will ensure that you can sit in any part of the room. The color and image quality will be almost the same everywhere. You can close your eyes and purchase the Vizio SV420M. It will certainly give you value for money.

User Reviews
We like the video part of the Vizio SV420M, but we’ve had some issues with the audio. I disagree with the review’s assertion about SRS TruVolume “which controls the variations in the sound levels. The advertisements will not sound too loud or there will not be a sudden rise of sound level while changing channels.” We haven’t found this to be true at all. With the SRS TruVolume factory setting, the sound levels are all over the place. Not only that, we’ve found that in playing an occasional DVD that we can’t enough volume to comfortably hear the movie, even with the audio pegged. It may just be the DVD, but it sounded fine on another TV. So, we’re considering whether to put the TV back in the box and haul it back to Costco to exchange it for another SV420M.
Has anyone else had problems with audio levels on the SV420M?

I have the SV420M and the Samsung LN40B530 at home right now and have been swapping them back and forth to compare. The sound and picture straight from the box is better with the Samsung (picture a little bit, sound way better) You need to tweak the Vizio audio equalizer to get decent sound. After fine tuning both I would say the picture quality is equal, except when it comes to motion. The 120hz of the Vizio makes sports (hockey especially) a better watch. Paid $849 on sale for the Vizio the cheapest Samsung 120hz / LN40B610 is $1199 on sale. I am a Samsung fan but its not worth $350 more.
just purchased a new 37″ with the Tru Volume. worked ok for a couple of days, but now sound is all over the place up and down.
