    Just wondering what this is? Scan Velocity Modulation? Toshiba only?

    Are there any other "features" of other brands of RP HDTV's that are lame and advisable to disable?

    Several TVs have this; it's like edge-enhancement applied by the TV- my 40-inch Mitsubishi picture tube came with this and applied a thin outline to the edge of everything onscreen. Very annoying, and made it hard to read onscreen text a lot. I had to go inside the set and unplug something from the board on the end of the tube to disable it, but some sets will let you turn it off electronically. I don't know why they have these on TVs since most people who know about it don't want it!

    Cool. Thanks. Thankfully it can be defeated though.

    SVM = scan velocity modulation. Bordered images, with one being darker than the other, are scanned more frequently (velocity modulation) so as to give the appearance of sharpness. But it's nothing more than a built-in distortion at the expense of true resolution. Unfortunately, however, the mass-market buyers prefer it.

    With most sets, SVM can only be disabled from the service menu. But more and more sets are offering this option in the user menu (the Sony WEGAs).

    It is nearly always best to defeat SVM.

    Can I assume that sets I see in the Future Shop like the Sony KP57HW40 and Toshiba 50HX81, Hitachi and Panasonic PT series all probably have SVM enabled? Future Shop is a change of electronics/appliance stores in Canada.
