Xbox V1.6 Possible Video Output

1. I don't think you can on a 1.6. You need a VGA BIOS, and I don't think there's a 1.6 VGA BIOS. Someone else might be able to confirm or deny this........
2. No. You can have component video output at up to 1080i, but not native HDMI.

However, you can buy external adapters for both, although judging by some of the reviews the quality seems to be a bit variable.

No 1.6 VGA bios, there's no documentation for the xcalibur video encoder.

OK guys, yesterday sealing around I found this topic
http://forum.console-tribe.com/tutorial/t-...vga-129173.html
I know it's in italian, but in few words, the guy over there claim to have a v1.6 and with that hard mod. he adds a vga output on a xbox v1.6. Do you think it could work or not ?

Yes, if your monitor supports sync on green ........ BUT your picture will have a serious green tint. You need a VGA BIOS to change the output from the Xbox so that it is RGB rather than component (YPbPr), and there is no 1.6 VGA BIOS.

Anything is possible, and they already exist (its part of what is in the x2vga) I saw a post about a guy looking to do this cos he didnt want to have to run a separate bios for vga, his plan was to build the YPrPb to RGB converter and contain  it in the xbox and then connect it to a VGA jack, therefor giving him a VGA and component output with correct colors without have to have a VGA bios running. A quick google turned up this which looks like a basic circuit diagram for converting YPrPb to RGB. If you monitor doesnt support sync on green then you will also need to build the separate sync separator circuit too.

VGA is very tricky in Xbox ver 1.6. The M$ guys just changed a lot to the Xbox in this version and one of those things is the Video Encoder thing.

The only suggestion I would have is get yourself a Component Cable and buy a Component to VGA Adapter. This way (depending on you monitor/tv) you can play most Xbox games in 720p and use most homebrews with 1080i.  I think this is way easier and cheaper than building your own VGA RGB converter thingy.

That wont work, since the 1.6 will only be outputting color signals on the Blue and Red connectors (Pb&Pr) cos that is how component works, (color on red Pr and blue Pb wires and sync & luminance on green Y). The earlier versions have a bios available to make the xbox output the green color on the Y cable so you get:
Sync and green on Y (green cable), Red on Pr (red cable) and Blue on Pb (blue cable). So your two choices for a 1.6 is to build a separate YPrPb to RGB converter to get the green color from the PrPb channels  and put it on the Y channel (like I already suggested), or play games with the missing green color signal, i.e. green tint.

Emmm, I didn't meant to make a cable with a VGA end and a Component end. I said that he needs one is these little boxes...

Like in Here

Then all he need to do is connect the Xbox with Component or a HD pack to the box and use a VGA monitor like THIS.

I'm pretty sure this is gonna work for what the guy needs. Connecting a Monitor to his Xbox. If he's lucky his monitor might support 720p and play some games that way.
