Hi, NateMan99, LCD Tv and LCD monitor are really very different in LCD panel and electronics. LCD TV panel usually has high contrast (>1000:1), high brightness (>500nits), good color gamut (NTSC/xvYCC), and wide view angle (>170 degree). To achieve these advantages, LCD TV panel has bigger pixel size. However, LCD monitor's panel is much poor than TV panel. It usually has 500:1 contrast, 300nits brightness, and sRGB color space, which is much smaller than NTSC. Since Tv need to receive many kinds of signal, such as Composit video, S Video, YCbCr/YPbPr, HDMI, VGA,DVI, 480i/p, 720p, 1080i/p, LCD TV electronics are much complex than that of LCD monitor. LCD TV embodys de-interlacer to convert interlaced signa into progressive signal for LCD display, and scalar to scale up/down the input signal to the resolution of panel.However, LCD monitor usually only receive VGA progressive signal from PC, so de-interlacer is not needed. The scalar in LCD monitor is usually much poor than that in LCD TV. To improve image quality, LCD TV adopts many advanced image/video enhancement techniques, such as 3D noise reduction, color enhancement, fresh tone adjustment, DCDi, and so on. All of these are not applied in a LCD monitor. From above, we can see that LCD TV is really different with monitor, though they looks same. To development a good TV set, company must focus on color reproduction, moving object response, dark picture display, noise reduction, channel sensitivity, and so on. TV is a much complex product than monitor.
summer: Dell has been making TVs for years. This is the third 37" LCD they've made, and the fourth 32" to my knowledge (may have been more). They also make plasmas (42" and 50").
Also, Dell, like HP, does not make the panels. For the previous iteration, the panels came from a variety of manufacturers, including Sharp and, if I'm not mistaken, Chi Mei.
As for the complexity of making a television over making an LCD monitor, you are right. Dell's TVs (particularly the 37" and 42" models) have historically had problems with accurate color reproduction, posterization, and false contouring. The 50" plasma is apparently a pretty decent piece, and most people also seem satisfied with their 32" models, as well. They are certainly not "high end" quality. Perhaps akin to Syntax or Scepter
