Re: HDMI-VGA Adapter with chip GBP 12, free shipping

Maybe just bad luck and you have one of the monitors which is incompatible with this device? Seems to be working OK for most people. :?:

Not so. It's the RPi that's the problem.

I tested the cable from the HDMI output on my Windows laptop to that VGA monitor to ensure it wasn't the cable that was faulty. It isn't - I got a picture with no problems at all.

It's all to do with the RPi and config.

My only hope is that the HDMI to DVI conversion isn't as painful. I live in hope....

No, it's the combo of monitor, Pi, adaptor and settings that's the problem. I'm glad your neewer adaptor is working. If you had another type of VGA monitor handy it would be interesting to see if it worked out of the box, like most of the rest of us experienced (more or less). I think you're the first person to report a total failure with this adaptor on here.

My Neewer HDMI to VGA adaptor arrived today from Amazon http://www.amazon.co.uk/gp/product/B007KEIRNG
Connected it to an AG-Neovo F419, initally as expected got a rather horrible pink screen skewed to the left, then set Config.txt to
  • hdmi_drive=2
    hdmi_group=2
    hdmi_mode=36
    disable_overscan=1
and perfection resulted. I understand the reasons for using a TV but it doesn't half cheese you off in no time, this is much more like it.

I came across the same adaptor. I've tested it at 1920x1200 and it works pretty well. The picture quality is not amazing, but it's acceptable. I made a video demonstrating it here:

My config.txt is:

hdmi_group=2
hdmi_mode=68
disable_overscan=1

Hi - first post here and hope of some help. I tried a passive lead HDMI-VGA lead with no success of course (should have researched a bit more!), the Neewer one from Amazon states 7-23 days lead time so bought a 'Cable Matters' one which turned up next day and works fine

regards and look forward to contributing more!

I have one of these, but have failed to get it working so far. I have fiddled around with a config file, but with no success, any ideas?

Power issue? Seems to draw some power, so if you have a soso adapter that lowers the voltage when under load that might be a problem.

A (neweer) adapter that doesn't have its own power supply, tries to draw some 400mA from the R-Pi, not only does that mean that your PSU will probably be overloaded, but it also means that a diode between 5V and the HDMI wire the neweer adapter tries to draw the 400mA can be damaged, as its only rated 200mA, for such adapter to work:
1) The adapter needs to supply an additional 400mA
and
2) The BAT54 diode (D1) must be bridged, or replaced by a diode that can conduct at least 400mA, and has a low drop of 0.2 Volt or so. (and has the same SOT23 package) The PMEG2010AET is such a diode.

Handles audio also at just $59.  I'm thinking it may be a good fit for giving presentations/training at locations where you don't know if the venue will support HDMI.  This plus an RPi is still cheaper than an AppleTV, and the RPi can support AirPlay (a chief excuse for getting an AppleTV) which is great for presentations.
Jesus, I could get a new HDMI monitor for almost that!
