I have the original Surface Pro 128 and I've been trying to get the picture on m larger desktop monitor. First I tried Chromecast, which, although I got it to work was unacceptable due to the long delay between an action on the Surface and resulting change in the video on the screen. I bought a cheap Chinese cable and could not get it to work. I tried hooking the Surface up to a Sony Bravia TV with an HDMI connection and it wouldn't work there either so I figured the cheap cable was crap and threw it in the trash ( although it is still recoverable ). I tried trimming the plastic ends around the connector to make it go in better but that didn't help even when I completely removed the covering. So I ordered a Microsoft adapter for the Surface Pro and it came today. NO LUCK Same story. Will not work on either my desktop monitor or the Sony Bravia TV. Since the Chromecast worked I presume there is a signal being outputted on the little mini-connector on the Surface. But no matter what I do I can't get either the cheap Chinese cable or the genuine Microsoft expensive cable to work. Any suggestions?
