Digital Cameras Photo Reviews of 12ftVGA to 3 RCA component video cable (HD15 - 3-RCA)Customer Review: Works with AppleTV and older projector Summary: 5 Stars
I purchased this cable to attempt to connect my AppleTV to a Philips LC6131 projector. This projector is now 10 years old (it was only sold in Europe), but supports NTSC and claims to be "HD Ready" supporting 720p and up to 1080i. However, it has a native resolution of 800x600 so I was skeptical how well it would work. Also the projector does not have an HDMI input, but does have the ability to accept Component video via it's "data" (VGA style) port.
As an aside, I've been enjoying playing videos from my MacBook Pro via a DVI to VGA adapter. That works really well.
When this cable arrived (it took about a week from when I ordered it), it took me about an hour to figure out how to make it work properly.
Here's a rundown of the issues I had to resolve.
1. At first the colors were all green, only a partial image appeared and I had a lot of flickering and ghosting.
Solution: The AppleTV defaulted to 480i resolution. It turns out this projector doesn't like any "interlaced" format. 576p, 480p and 720p seemed to do better.
Note: The AppleTV's maximum resolution is 720p. While it supports 1080i and 1080p output, that output would be upscaled by the AppleTV.
2. When I would change video formats on the AppleTV, I would occasionally (but not always) lose the display on the projector. Even plugging my MacBook Pro (via above configuration) would no longer display.
Solution: Buggy projector. Power cycling the projector resolved the issue.
3. Final image on the projector had a very strong blue tint to it.
Solution: Burried in the menus on my projector is a setting to change the format of the input for the "Data" port. Options were "Computer" (where I had it), "RGB", and "Component". At first changing it to "Component" did not produce an image. However, when I took problem #2 into account, rebooting the projector solved the issue and I got an image.
Note: The projector supports both YCbCr and YPbPr modes. Though the first scan was for YCbCr and the AppleTV prefers YPbPr. After some going back and fourth and rebooting the projector again, it finally shows YPbPr on the screen when it finds the image.
4. The image would occasionally be out of alignment at the 720p setting.
Solution: Change the AppleTV's output ot 576p and it displays perfectly. Since the naitive resolution of the projector is only 600 lines anyway, it's the closest fit.
In all it took me an hour to get here and now that it's working I'm very happy.
One side benefit is at this setting my projector no longer "overscans" my 16:9 screen. Previously it would produce a 4:3 projection, even if the actual image was 16:9, thereby lighting up parts of the wall above my screen. With these new settings it only lights up the actual 16:9 screen. A subtle but worthwhile difference.
