You're going to convert from Component to HDMI? That's not just an adapter then, that's a converter and could potentially add some lag to your game. Do you only play on a PC monitor, or do you play on an HDTV as well?

In my mind the best middle ground between cost and quality would be a Tuner card that could capture component HD that you just split and also run to a HDTV via component. A better option (but more expensive) would be an HDMI duplicator and run one HDMI to a TV and the other to a HDMI capture card (these are expensive).

Yeah it is a powered HD converter that changes the component HD cable into HDMI format. I saw a vid on youtube of a guy testing it and well see for yourself. He had no lag:



my pc monitor is optimal for gaming as well and isn't like a plasma tv that gets insane amount of input lag for HD.

Nice, so you'll feed the component input into the PVR and then HDMI into your monitor?

Early plasmas did a lot of image processing that caused "input lag" but newer ones have reduced the amount of image processing and many have a 'game mode' that disables the image processing altogether to eliminate the input lag.

I'll be feeding the xbox HD component cord to the PVR as I am supposed to, then the output components for the pvr will be converted to my pc monitor. In a way all that is happening is the HD cord is changing from component to digital HDMI and since the devices i am using to change the signal are powered it wont bog it down at all.

I figure is this many people do this exact setup to play games on a pc monitor with the PVR connected and no complaints about any HD lag then I am assuming it will run well. I've seen a lot of competitive gameplay where fast actions are required while they were using a setup like this and it seemed their movements were not delayed at all.

I dunno, converting from component (an analog connection) to HDMI (a digital connection) will almost certainly introduce some lag but it may be minimal. I'm still not completely certain that I understand your plan for connecting it all up - maybe you could throw up a vid of your setup after it gets done.

Actually, re-reading your other post make me think I do understand what you are planning to do. You are going to plug the component input into the PVR and then the PVR will feed into your computer and you will be able to see what is captured on your monitor...

If that is the case you will almost certainly see some noticeable input lag. Even with the video being hardware encoded by the PVR before entering your PC, that process takes time (we're talking milliseconds here) that compounded with the time it will take your PC to display the video feed out to your monitor (very little time) my guess would be that you would end up with something like a 200-400 millisecond lag (up to half a second).

My suggestion would be to simply split your component output from the xbox and run one to the TV and the other into the PVR. I would bet you $20 that you would see slight lag on the monitor.

Well my setup is going to be the exact same as the youtube video and it appeared he didn't have any lag so i think I'll be alright =)

More power to ya! I'd still love to see a video of the setup once you've got it running!
