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

B007QT0NNW -- "Kanaan" HDMI-VGA
http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=130699741793 -- eBay is
swarming with $16 converters all like this one.
This adapter -- http://www.ebay.co.uk/itm/300692770623 -- works from 640x480 up to
1920x1080, audio over HDMI works too. Sadly the IC's on the PCB have all been
scrubbed. Requires HDMI boost and overscan, config.txt settings for 640x480@60Hz:
hdmi_drive=2
hdmi_group=2
hdmi_mode=4
config_hdmi_boost=4
overscan_top=-30
overscan_bottom=-30
overscan_left=-30
overscan_right=-30
According to user "Mortimer" -- HDFuryPro HDMI to YPbBr/VGA Converter found on
Amazon -- http://www.amazon.co.uk/Inputs-Component-Video-YPbPr-Converter/dp/
B00797ZZ4S/ -- Works with Raspberry Pi. Tested against a Philips 170B 1280x1024
LCD monitor, producing a full native resolution image. Not tested against a Component
Video TV yet, and audio has yet to be got working. The config.txt settings used are:
hdmi_drive=2
hdmi_group=2
