I bought this to use with a Raspberry Pi and an old, but still good, LG Flatron L1510S LCD monitor. I imagine many Pi would like to make use of a similar old VGA panel and for £15 this converter is a cost effective solution. Using the Pi I have a very sharp display at 1024*768 60Hz, which I think is the maximum my VGA monitor can support. It took quite a long time to get the display to work but the problems were not really to do with the converter. Firstly, I found the HDMI plug on the converter a very snug fit in the HDMI socket of the Raspberry Pi (which is good), but initially I did not have it pushed fully home which meant of course that the monitor received no signal. Having worked that problem out I had to create a config.txt for the Pi. I found the following settings worked with my monitor:
# Settings for Flatron VGA monitor
# 1024 * 768
# Force HDMI signal even if monitor not detected
hdmi_drive=2
hdmi_group=2
hdmi_mode=16
hdmi_force_hotplug=1
disable_overscan=0
hdmi_mode=16 is the display resolution at 1024 * 768. Full information is at[...].
Having discovered the correct config.txt settings the only further issue was that the screen kept blanking and the Ethernet controller kept going down. I found that the solution to these problems was to power the Pi from my laptop rather than the wallwart USB power supply I was using. The converter draws a significant amount of current from the HDMI port and in my case this appeared to exceed what could be obtained from my power supply. Powering from the laptop's USB cured the problem.
