Toshiba Regza 42ZV555D: "World's first" upscaling TV
That's right, you read the headline correctly. Toshiba has just claimed to have created the industry's first upscaling TVs, the Regza 42ZV555D and 46ZV555D LCDs. With such bold boasts flying around the Internet, we feel like making a few ourselves. Did you know that we invented blogging? Or that without Crave, there would be no Moon? No, we didn't think so, either. But we've looked into it and it's true. Honest.
Let us explain why we're stroking the skeptical cat here. All HDTVs have upscalers built in, because if they didn't, when you came to watch something that was shot in a resolution different to that of the screen, you'd end up with a postage stamp-sized bit of video. If you were watching something with dimensions of 720 x 576 pixels, it would float in the middle of a 1,920 x 1,080-pixel screen. We've lovingly demonstrated this concept in our image above.
In a high-definition TV, the smaller, standard-definition image is stretched to fit the full-screen resolution. The TV's upscaling hardware will also apply some video processing to make it look as good as possible. It will do some additional processing to turn a standard-definition, interlaced picture into a progressive one because LCD and most plasma TVs can display only a progressive image.

Selection in regards to lcd brackets is to purchase a tilting mount that it perfectly suited for any LCD TV which is situated closer to the ceiling of the room and it permits you to look upwards at the TV and also provides you the ability to tilt the screen in a downward direction to help improve the viewing angle of the screen.Another piece of advice would be to mount the bracket to a solid wall.tv wall mounts can be fitted to make efficient use of space in any room
