    Hi

    I have the SL410 with intel GMA 4500mhd video card and an older tv that does not have hdmi. The hdmi converters are way too expensive for something I'd only use casually but I was wondering if I could use a vga to component cable instead. From what I've read it sounds like the video card might be able to support but was wondering if anyone's tried this.

    Found this with a google search, seems to be related to your problem ( VGA to RGBHV via modern IGPs - possible? - Graphics cards - Monitors/video):

    "The problem lies in the TV/monitor's input specs. Component connections can carry YPbPr or RGB video. YPbPr is the norm for TVs, RGB more for computers. Some TVs allow RGB signals but not all do. There should be a setting in the component input settings but generally if the TV supports d-sub input then it might handle RGB over component."

    So the issue is that a VGA port sends RGB (Red-Green-Blue) values per pixel while tv component is set to receive YPbPr ( YPbPr - Wikipedia, the free encyclopedia). This will more than likely cause a problem.

    I do not have one of these cables nor a laptop with the intel 4500 graphics card in question, so I can't definitively answer your question. However, the links I found do not look promising. Whichever route you look at, it seems that a transcoder is going to be your best (an unfortunately, most expensive) bet.
