My TV has 1920x1080 = 2,073,600 pixels.
The easy answer: a standard definition television does not have any pixels- rather, the electron beam projects on the screen a set number of fields, alternating between even and odd fields every 1/60th of a second. This is known as interlacing. The dimensions for Standard Definition broadcasting are 720 horizontal by 480 vertical in the US (NTSC standard), 525 vertical in Euope (PAL). LCD and Plasma screens on the other hand DO have a set number of pixels, which is 720x480 for standard def, and either 1280x720 or 1920x1080 for high-def.
This is more info than you asked for, but I'm in a giving mood... the 1280x720 is usually presented in progressive scan mode, as opposed to an interlace scan. This means that all 720 fields are displayed at the same time, and are updated once ever 1/30th of a second (or 1/24th of a second, for a more "film" look). These formats are referred to as 720p30 and 720p24. The 1920x1080 format requires a huge amount of bandwidth to be broadcast in a progressive method, hence is usually broadcast in interlaced scan which cuts the amount of signal in half at any given time- this is usually referred to as 1080i60.
they vary on resolution. If you have a conventional or HD
The numbers vary based on the type of TV, the model, etc. For example, if you have a HDTV (high-definition TV), you will probably have a higher resolution. Pixels are the individual color dots on a screen, and if the TV is a high-resolution TV, it means it has a higher number of pixels. For example, the highest resolution available today is 1080 pixels (1080p). The resolution of a TV should be specified in its manual, so you can look it up there; you could also google "TV resolution" or google the model of the TV to see its resolution.
I only bought my TV about 2 months ago, so it is a 1080p TV. However, remember that the resolution varies by TV.
