Essential Info

Wish you could surf the 'net or play computer games on your big screen TV instead of straining your eyes on that close-range computer monitor? Maybe you want to show your dinner guests a slide presentation of your digital vacation pictures directly from the entertainment center, rather than having them crowd into the home office to stand around your PC. Or maybe you just want to use the TV to make sure your teenagers really are using their PC to research homework, instead of navigating inappropriate Websites or wasting time in chat rooms. You can do all these things and more thanks to the Wireless VGA/TV Converter!

    Wireless Transmission
    Unlike standard VGA/TV converters, which require a hardwired connection between a PC and the TV, this model transmits audio and video signals without wires. It's like getting a VGA/TV Converter and a separate wireless video distribution system for the price of one product! Signals are transmitted over the high-bandwidth 2.4GHz band, ensuring picture quality that's as good as a cabled connection.

    Easy Plug-and-Play Set-Up
    The Wireless VGA/TV Converter is a totally plug-and-play device — no software is required, giving your PC one less reason to lock up and crash. The converter is compatible with any PC or laptop (including Macs) with HD15 VGA standard connection. It handles resolutions up to 1600 x 1200, and supports practically every video system type, including NTSC, NTSC-EIAJ, PAL-N, PAL, PAL-M, PAL combination-N and SECAM (via RGB out). It also supports CVBS, S-Video or RGB video outputs via wired connections.

    Compatible With Older TVs With Optional RF Modulator
    Have an older TV without composite inputs? No problem! Simply use a Channel 3/4 RF modulator (#77041), which converts the composite video signal from the video converter to an antenna signal which can be viewed on channel 3 or 4.

    Fine Tune Images Directly From the Transmitter
    You'll also be able to fine-tune the television image directly from the transmitter. You can even toggle between zoom and normal displays for the converted computer displays! Simply touch the MENU button when you want to cycle through other functions, including freeze, HSIZE, VSIZE, brightness, contrast, hue, saturation, video standard, flicker, OSD color and reset.

    System Contents
    The system includes a wireless transmitter, wireless receiver, an S-Video cable, a video cable, a PC to TV audio cable, an audio pass-through cable (so that your existing monitor continues to work normally without swapping cables), an H cable for VGA connection, audio/video cables for the receiver and power adapters. Portable notebook computer users will also appreciate the included battery pack, giving them true mobile freedom throughout the home, even if there's no power available (uses four AA batteries, sold separately).

    View Your Computer Screen From More Than One TV
    If you want the ability to view your computer screen from more than one TV — without having to disconnect and reconnect the receiver that comes with your kit — simply order an extra receiver (#7743BR, sold separately).

    VLADIMIR -- san diego, CA   3/4/2010
    VERY poorly designed unit with terrible signal quality. Don't waste your money and time trying to get it to work. Check something else on the market. Oh yes, forgot, it creates such a strong interference that many other wireless devices stop working at the same time this unit is running.
    JASON -- phoenix, AZ   4/17/2008
    After talking with the customer support person the device is not designed for converting a computer image to a TV. The product is not designed to handle the DPI output of a compuer.
    ROGER -- san angelo, TX   3/3/2008
    High quality and affordable product. If you want to switch between computer and TV using the same screen, this is the way to go (as opposed to converting VGA to RF).
    JAMES -- spring hill, TN   1/19/2008
    I was not able to have it work because the menu feature was not accessible. Plus it would not read my monitor size (1440x900) and I was going to have to change it to (800x600)in order to view the monitor. I was wanting a higher quality output from my two computers to view on the 42 inch TV.
    SHAWN -- cahokia, IL   1/16/2008
    Installation was pretty straight forward. What I don't like is now that it is connected to the TV, it distorts the TV after I have used it. It takes a lot of setting changes in order for the TV to come back in correctly to regular channels.
    ROBERT -- wilsonville, OR   12/7/2007
    Video quality is terrible
    TREY -- selmer, TN   9/20/2007
    works...but has lots of static...not good enough quality to do presentations or for the money spent...
    KEVIN -- spencerville, IN   8/20/2007
    Service and support from Smarthome is excellent. This product should not be on the market, however, as it was very poor quality signal transmission even at 15 feet from source. Un-usable and had to return.
    BRANT -- searcy, AR   8/17/2007
    Terrible product! It does not work!!
    ANTONEY -- mahopac, NY   5/13/2007
    product not working yet. no dislay on my monitor after I connected the scan wire to PC and then to monitor. I don`t know if the scan wire is bad. So I probably need some help on this.
    ROCHELLE -- parklands, XX   4/2/2007
    The quality of the connector when viewing presentations is very poor. The product is unfortunately not functioning to expectation and will most likely not be used.
    LINDSAY -- independence, MO   3/8/2007
    The ordering and receiving of our order was fine; however, we were not satisfied with the product. Upon using the tv converter, we experienced very poor picture quality. It was not what we were expecting. In fact, we returned the item.
    ALEKSEY -- round rock, TX   2/23/2007
    I received package very fast, and content was as described. Everything was not damaged during transportation - so package was secured. Converter works perfect in our house - using one of the channels I am able to send signal downstairs (three walls, near 30 feet) to my 46" LCD 1080 Samsung. Quality on TV screen even better than on laptop at the same resolution and even better than many of cable channels. Highest resolution is limited by TV but not by converter. I have no interference with three Sony cell phones, Panasonic wireless home theater system and Linksys wireless router running at the same time. Installation is easy, may be pictures in owner manual could be little bit better printed. Price is reasonable. So I am able now to watch my online TV service in convenient fashion without wires and needs to move laptop from office desk. Overall experience is A++++++ Would recommend to others. Thank you. You can place my review online on yor website. Gashev A.
    TERESA -- westchester, IL   2/12/2007
    Wireless device did not function as anticipated and was returned for a full refund.
    TIM JR -- eau claire, WI   1/28/2007
    When I first received the product, I thought I had been took for a ride! The power button didn't work correctly, the function of each of the keys was incorrect and it just wasn't compatible with my laptop...that is until I called the customer service line. WOW! is one of the many things that I can say. The customer service man that I spoke with said that there definitely was a problem with the product and that there would be a replacement sent out free of charge. A return label for FED-EX was mailed to me and I shipped it out the next day. Within about a week or two I believe I received the new one and have used it on a regular basis in our Church building. It saves from having to have all those cords run for two different signals and it even works like it is supposed to! This is one AWESOME product! Thank you again Smarthome, you definitely have a repeat customer here! Rev. Hallett, Jr.

    I had a setup problem with the PC to TV and your support group was very responive.
    NILTON -- pawtucket, RI   3/15/2006
    i'm satisfied with my product.
    JONATHAN -- tulare, CA   1/30/2006
    Good service . Great product!
    FRANK -- santa monica, CA   1/9/2006
    Smarthome's service was great, very timely shipped and received. The product didn't work to my expectations, so returned product. Return of product service was excellent also.
