Sanoxy HDMI to VGA converter (http://www.element14.com/community/groups/<br />
raspberry-pi/blog/2012/08/16/raspberry-pi-hdmi-to-vga-converter) , $27 from Amazon,<br />

already disabled overscan previously<br />
http://www.amazon.co.uk/gp/product/B007KEIRNG -- "Neewer" HDMI to VGA -- some<br />
issues discussed below: However, according to user "Tom1989" the same Neewer HDMI<br />
to VGA adapter burned out BAT54 Schottky diode D1 on the RasPi and broke its HDMI<br />
output: Serious HDMI Problems. What's that smell? Burning Raspberry!<br />
(http://www.raspberrypi.<strong>org</strong>/phpBB3/viewtopic.php?f=28&t=9819) . On that thread,<br />
"mahjongg" suggested the NXP (or equivalent) PMEG2010AET as a high-current<br />
replacement for D1. The PMEG2010AET has 1A max forward current, much greater<br />
than the BAT54's 200 mA limit which may be exceeded by your HDMI -> VGA<br />
converter. Remember that the converter's current must come from your RasPi power<br />
supply and go through the Micro USB cable and polyfuse F3, so you may get extra<br />
voltage drops and/or cause F3 to trip depending on how much current the converter uses.<br />
As always with board modifications, YMMV. Also on the "Burning Raspberry!" thread,<br />
user "pwinwood" reported the Neewer's current to be 400 mA, which is twice the limit of<br />
BAT54 diode D1. "pwinwood" also took the Neewer apart and added its own +5V<br />
connection adapted from a USB cable, which bypasses RasPi's Micro USB cable and<br />
polyfuse F3.<br />

B007QT0NNW -- "Kanaan" HDMI-VGA<br />
http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=130699741793 -- eBay is<br />
swarming with $16 converters all like this one.<br />
This adapter -- http://www.ebay.co.uk/itm/300692770623 -- works from 640x480 up to<br />
1920x1080, audio over HDMI works too. Sadly the IC's on the PCB have all been<br />
scrubbed. Requires HDMI boost and overscan, config.txt settings for 640x480@60Hz:<br />
hdmi_drive=2<br />
hdmi_group=2<br />
hdmi_mode=4<br />
config_hdmi_boost=4<br />
overscan_top=-30
