VGA's main problem is the tv may have difficulty recovering the pixel clock. This can result in slight horizontal blurring or shimmering. But DVI->HDMI also has its problems. Many HDTVs don't allow you to disable overscan on HDMI inputs, which prevent you from getting a 1:1 mapping between the PC's pixels and the LCD panel's pixels. This problem is worst than VGA's problem. And that's not the only problem with HDMI. Many HDTVs' HDMI decoders only accept data in the YUV color space, not RGB that is native to PCs. Although most computer video cards will convert from RGB to YUV, there are two problems: 1. Some very bright colors may be clipped. 2. The chroma data is subsampled, so bright colors can appear as if they are bleeding into the immediately adjacent pixel. It really depends on the tv. When everything falls into place, HDMI is the best. But that rarely happens, leaving VGA as the best option on many tvs.
