HTPC Image Quality Problems
« on: December 24, 2013, 09:52:42 PM »
I have an HTPC, and on the occasions that it is connected to the HDTV, it is connected through HDMI. So naturally the image quality is fantastic. On my old CRT TV, I have the VGA port outputting to a converter box http://www.amazon.com/Lenkeng-104724-Monoprice-VGA-RCA/dp/B001CJOLBW/ref=sr_1_1?s=electronics&ie=UTF8&qid=1387947003&sr=1-1&keywords=Monoprice+VGA+to+RCA. Then S-video from the converter box running to the CRT TV. While the quality is all I could hope for, on fast moving scenes, or scenes with flashes of lightning, the image has a "rolling shutter" effect, such that there is a horizontal disconnect where the previous frame is on the bottom and the new frame is on the top. However, it is an incredibly slow correction, it takes about 8 frames for the "rolling shutter" to finish "rolling". Any ideas on how to avoid this besides buying another HDTV?
