Problem with HDMI to RCA converter

[alien91]

Hello, I register to this forum in hope to find an answer to a problem I'm having.
My friend wanted a converter not too expensive to send casually from his PC (through HDMI) to his old CTR 32" so I searched a little and saw on YT some little converters for less than 15 bucks http://www.cafr.ebay.ca/itm/MINI-HDMI-to-3RCA-CVBS-Composite-Video-AV-Converter-Adapte...item46395fc31f so I gave it a try and unfortunately, it's not working at all with any resolution on the computer.
The switch on the converter is set to NTSC, I tried with different HDMI cables (1.4) and two different RCA components and always get the same result (see pic).
Any help would be welcome.

What resolution are you trying to use?

The converter won't change the resolution, and a CRT TV isn't likely to support a very large resolution. Start at 640x480 and increase it until the image is lost.

On a side note, I've not seen any cheap converters that work/work well.

I started with the lowest resolution on the laptop (800x600) and always had the same result. I wish I could try 600x480 but it seems I can't get this low.

The converter should be able to convert any of the supported incoming HDMI resolutions to a standard definition analog NTSC signal that any old NTSC TV with a composite input can display.

Try to set 720x480p(i) 60 if possible - this is usually not available directly and usually settable trough advanced options (graphic card advanced properties - HDTV video modes) - such simple converters may expect TV resolution at input. Set also converter in NTSC position.

Are you providing power to the device via the USB input? A user review of a similar (same?) device at Amazon claims USB power was required.

It looks like it uses a mini USB connector so an adapter like this should work:

Or use the correct cable to connect to a USB port on your computer:

Another reviewer said the NTSC/PAL switch was labeled incorrectly. So try switching that.

Thanks to all for your suggestions I appreciate it. I tried the resolutions from the advanced properties panel and I've been able to see some very distorted images through it (doubled vertically) at 60hz on the lowest resolutions such as 640x480 but anything above this look alike the pic from the first post. Switching to PAL just made the screen goes black and white and the NTSC gives a few greenish bars at the bottom and not much else. I didn't had any resolution options below 59hz and I suppose you meant 30hz by interlaced (I'm very noob with this)? I'll try later with another video card and give news if there's anything worthy, thanks again guys.
