Hi All:

I just got the Xbox HD VGA cable and am connecting it to my Ruby's Input-A VGA. I was using the component cable before but need that input on the Ruby for my STB so i thought i would connect the Xbox to the VGA input to make use of that input (and i thought to get better resolution than the component input could handle). When i go into the Xbox display settings, i can only get up to 720 resolution. When i try to select the 1080 resolution in Xbox, it does not display correctly on the Ruby and defaults to 1024x768 or something.

Am i missing something or barking up the wrong tree trying to get 1080i or 1080p to my Ruby using the VGA cable? Should i stick with swapping out the component cables instead? I use the Xbox and Ruby for HD Dvd's also.

Anyone? Cheers!

Umm, I believe the ONLY way to get 1080P is HDMI?

Well i dont know why it is not working. I used the VGA input with my Cable STB and that works fine (1080i) but i cannot get my Xbox to send 1080 via the VGA input.
Anyone?

Fairly common with the Xbox VGA. Not that I have any answer for you on it.

Can anyone provide me some tips to get 1080p from my Xbox with a VGA out to the Ruby?

VGA cannot do 1080i, but it can do 1080p. If your projector cannot do 1080p it will not work. If your projector is 1080p, maybe you can't accept 1080p over VGA on that model.

Does your projector accept 1080p over component? If so, just go that route if you've already proven it works.


Otherwise... Guess you're stuck with 1080i over component.

Can it do 720p??? With other devices have been able to do 1080i via the VGA connector is this an Xbox360 thing or what?

The package and Microsoft website may say that the 360 HD VGA cable supports 1080i, but sadly, it has been confirmed a misprint.

There's an issue on Sony units with 1080p via VGA. For some reason it locks to the wrong signal and displays everything in a boxed window. I've tried this with the Ruby and the KDS 70", no luck. Other projectors like the Sim2 HT5000 work like a charm with the signal, so it's not the source. Not sure if MS could fix this with an update, a PC would provide the possibilities of tweaking, the 360 doesn't of course. Didn't dig into this any further.

1080 with a VGA? That isn't possible. You can pick up a HDMI on amazon for like $5 now.

Huh? 1080-what? Obviously there's an issue with the 360 VGA output that won't work at 1080i. Besides that, VGA can carry pretty much any resolution, be it 1080i, 1080p or whatever. At some point you'll run into bandwidth problems, but that's another story. What exactly is "a HDMI" for $5? A cable? Not all 360s have a HDMI output.

Stephan: I think you are correct. I spent a few hours screwing around with the VGA input on the Ruby using the Xbox360 VGA cable. When i try to set the resolution on the Xbox to 1920x1080, the Sony reverts to a boxed resolution (1280x1024 or something). I can get the 720 resolution to work with the VGA cable but not 1080. I can get 1080i using the component cable but wanted to make use of the unused VGA input on the Ruby and i wanted to watch movies in 1080P.

So basically i need to buy new Xbox 360 HDMI version (which i am not going to do) to be able to watch HDDVD movies at 1080p. What a shame. I have a PS3 also and watching 1080P movies with the PS3 is sublime....I have reverted to using a component switch instead of the VGA cable. By the way, i have no problem using the VGA input on the Ruby connected to my Scientific Atlanta STB using a VGA-Component gender changer. And the Ruby received the cable signal fine as a 1080i signal. So the Xbox problem MUST be something to do with the Xbox and not the Ruby or cabling.

But that's 1080i, not 1080p. 1080i works, 1080p doesn't.
If this is just for watching movies via the HD DVD add-on, it's probably not as bad as you think. I'm not sure how the add-on handles 1080p, but alot of players have to fall back to 1080i from 1080p24, and then de-interlace to 1080p again to output 1080p60. So depending if the add-on handles it this way as well and the de-interlacer used in the 360, 1080i to the Ruby may give you the same or even better results.

I've done some testing with the PS3, an external videoprocessor and the Ruby on this. Outputting 1080i from the PS3 into the videoprocessor, let that do the de-interlacing and outputting 1080p from there to the Ruby gives noticeably more details than feeding 1080p directly into the Ruby. So either the PS3 has some bandwidth issues or the de-interlacing is just bad when it falls back to 1080i (if it does). The de-interlacing from the processor is better than the internal de-interlacing from the Ruby. It's been a while since I tested this, maybe Sony has fixed it with a firmware update.

In general, between 1080i properly de-interlaced to 1080p and native 1080p, there's no difference in quality. If there is a difference, it's the fault of the de-interlacer used.

Stephan:
Very interesting stuff. I have not tried updating the firmware on the Ruby. It has 400 hours. Maybe i will see if there is new firmware available and try the VGA again.
IMHO watching 1080p movies via HDMI from the PS3 to the Ruby is better quality than 1080i HDDVD movies via component from the Xbox360 to the Ruby. I have not done extensive side by side comparison, its just my informal observation.

Sean,

sorry, I meant the PS3 firmware update, not the Ruby. Sony is releasing update after update for the PS3, so they may very well have changed the processing in the PS3.

It makes sense what you say about 1080i from the 360 add-on vs. 1080p from the PS3... I bet you'll also notice a difference between 1080p from the add-on vs. 1080p from the PS3. The major difference is not the resolution, but that one is using a digital connection while the other is using an analogue connection. As soon as you go analogue, there's a conversion involved which also means there's a loss of quality. Unfortunatelly there's no way around it when analogue connections are used.
