Varför har den inte någon VGA-utgång?
I think it's an incredible project, and I'll certainly buy one for my son when they come out. I'm just wondering though if not having VGA is a bit of an oversight and I'd be interested to know why you made that tradeoff. I agree composite is great for places where old TVs are common, and HDMI is great for those of us who just want it as a novelty, it's just I can't help but feel that the people who could benefit most from this would most likely get one of these along with a free or very low cost second-hand monitor, which would almost certainly be VGA only.
Eben: The tradeoff is driven by the feature set of the BCM2835. Previous products in this line used an analog RGB TV output peripheral which could be hacked to drive VGA quite easily; irritatingly, for cost reasons, BCM2835 only supports single-channel (composite) video out, which prevents us from doing this.
I agree that the lack of VGA output is a very significant problem with the device, particularly in school environments, where (at least in the UK) there are often labs full of old analog monitors. Although we can’t afford to add chips to the baseline device to support it, we’re investigating three routes to add VGA compatibility in the future:
