VGA to Component with Hauppauge HD PVR

post #1 of 14
Thread Starter 
Hi everyone, I need to know if this will work ... i would like to use a CRT monitor and record my gameplay with my gaming edition HD PVR...




Basically, I would like to use my computer monitor, but it obv. has no component inputs so I was wondering if this would work without ANY LAG:

So I'm not sure if this will work but what I was thinking that may work was:

- VGA to Component cable
- VGA Splitter

So basically, I use an Xbox 360 VGA Cable
- connect the xbox vga cable to the vga cable splitter
- connect a VGA cable from the splitter to the monitor
- connect a VGA to component cable to the splitter, and the component side of the cable goes to the HD PVR....


would this possibly work?

No, it won't work.

A VGA to component cable doesn't give you a converted component signal you need to record on a Hauppauge PVR. Those kinds of cables exist to be able to input a component signal into a display that happens to accept both component video and VGA RGBHV video over a common 15 pin connector, but it does no conversion of one type to the other. RGB in a computer VGA signal is not the same electrically as Y-Pr-Pb component. RGB has separate horizontal and vertical sync signals on two more wires, the H and V leads, and component has sync encoded already into the Y lead. And the voltage levels are different between the two.

So it won't work unless there are some electronics involved to convert RGBHV format to Y-Pb-Pr component. A passive cable can't do that. You need a 'scaler' or 'scan converter' to do the conversion from 15 pin VGA to three wire component.

hi!

thanks for replying... so will I need an ATLONA vga to component converter in order to play with a CRT monitor and record my gameplay?

Please don't spend $300 on that device.

$40? Wow thanks! Just one question, will this device add any input lag, and will this work for sure? (if i'm using a Xbox 360 vga cable)

and also... will this converter work if I'm playing on a different resolution other than 1080p? because the HD PVR records 720p only. I don't want to record in 1080i. I'm using a CRT monitor, and for some reason, the 848x480 resolution seems to work good for my monitor, nothing is stretched out or looks weird.. though the image quality might not be the best... but if i play on 848x480, will this device upscale the picture to 720p?

thanks!!

unfortunately, it seems like you can't play 1080p with that VGA to component converter from monoprice, only the Atlona converter does that .. and it costs $300

On a recording of a video game you will never notice the difference between a recording made at 720p and 1080p. Not worth the money, ever, to buy a converter just to get that 1080p resolution out of it. It's just bragging rights and nobody would know the difference if you didn't tell them. Especially if you're going to post your recording online. Your recorded file size at 720p will be far more reasonable than one made at 1080p.

The only way you'd see true 1080p out of it is if you were putting 1080p into it, and no scaling is being applied to the input signal. Once you need to use the converter's scaling to convert from one input resolution to a different output resolution, all bets are off and the quality will suffer anyway in any conversion. That will be true for a $40 converter and a $300 converter (and also a $3000 converter; I've used a few in my work).

And no, if you're watching the live game play on the converter's VGA monitor loop through output connection, you shouldn't see any time lag on that monitor. That connection is just an amplified repeat of the input signal and there's no digital processing (which causes delay) applied to that output. It's when you have digital signal conversions that you encounter lag. You will definitely notice that what you see on the computer monitor screen you're using to monitor the PC making the the Hauppauge component recording on, that there will be maybe a 1-2 second delay behind what you see on the computer monitor on the VGA monitor loop output. That makes using the Hauppauge's feed completely useless for playing the game; you must use the VGA monitor output on the converter to do that.

Hey what's going on ....

I have all the required cables to set this up as I also want to play on my computer screen and record with my HD PVR.

I can't seem to set it up right though... Any help would be appreciated ...

thanks!

I have the hauppauge as well for the same exact reason, to record gameplay off the xbox and ps3 and it was an extreme pain to setup. I have gone through 3 converters that have been utter garbage so far that would randomly drop signal or cause the colors to be messed up in the game.

So before I get into everything let me tell you the 'quick fix' that might work for you since Im assuming when you say it doesnt work it means you are not getting any picture?

I find that when you reconnect everything to the 'hopper' and you get no video there are a few steps that fix it:

1. make sure all cables are plugged in (of course wink.gif )
2. close out of the PVR software on your pc
3. unplug the usb to the hopper from your pc
4. unplug power to the hopper
5. startup the PVR software
6. plug the hopper back into your pc via usb
7. plug the power to the hopper back in.
After 30 seconds or so you should be golden. (note that the gaming system should be ON this entire time)

Assuming that doesnt work we are going to need more details on how you have each device connected and what it is connected to.

Note - When everything is setup correctly only the video feed to the PVR software will be delayed, you should not see any delays on the TV

Thanks for the reply. I will list the equipment I have and you tell me if it is possible for me to play and record through my computer screen. I may be missing one part or maybe not.


I play my xbox 360 using a vga cable that connects to my computer screen.

I have this vga to component cable...

I also have the pc to tv converter ...

I just recently bought this component to vga audio converter ...

I also own extra vga cables and hdmi cables ....

My desktop computer is hdmi compatible as well.....





So I am missing the Atlona VGA to component/component to vga converter ...
http://www.bestbuy.com/site/Atlona+-+VGA-to-Component/Component-to-VGA+Converter/Scaler/2715072.p;jsessionid=D99CAF24514640835FF794843625F32B.bbolsp-app05-43?id=1218672098802&skuId=2715072&st=VGA%20to%20Component%20(YpbPr)%20Converter&cp=1&lp=2

Is there anyway I can get my setup to work without the Atlona? Should I get the VGA to component Trexid is talking about?

Thanks

I think the issue here is trying to convert off VGA before going through the hopper. The way I do it is using this cable.
http://www.xbox.com/en-US/xbox360/accessories/cablesnetworking/Xbox360ComponentHDCable
I connect the xbox direct to the hauppauge. I then connect the other side of the hauppauge to this
http://www.amazon.com/gp/product/B0016SN49Y/ref=oh_details_o00_s00_i01
This is because my monitor has HDMI input so you would use a component->VGA

But this setup works. However, really read reviews on the converters as the first 3 I tried were utter garbage (some despite the reviews) so it can become trial and error in that stage.

Thanks I will try this out ...

I have another question ...

What is the difference between this (http://www.amazon.com/gp/product/B0016SN49Y/ref=oh_details_o00_s00_i01) and this other piece of equipment I have (http://www.ebay.com/itm/1080P-Component-5-RCA-YPbPr-AV-Video-to-HDMI-Converter-for-Wii-PS2-XBOX360-DVD-/200807661974?pt=US_Video_Cables_Adapters&hash=item2ec111c196)

It is compatible with HDMI cables...

Why can't I just use this to plug my xbox 360 directly to the hd pvr with this cable (http://www.xbox.com/en-US/xbox360/accessories/cablesnetworking/Xbox360ComponentHDCable) and then plugging the hd pvr cable to the converter (http://www.ebay.com/itm/1080P-Component-5-RCA-YPbPr-AV-Video-to-HDMI-Converter-for-Wii-PS2-XBOX360-DVD-/200807661974?pt=US_Video_Cables_Adapters&hash=item2ec111c196) ... Finally plugging the HDMI cable to my computer screen ...

I get an INPUT NOT SUPPORTED message...

How would it work your way Pik4chu??? Isn't that the same direction you are pointing me in?
