One thing to look at: Alienware systems are notorious for refreshing at 61Hz, instead of 60. If you get a VR920, and the image is flipping, like an old TV with the Vsync out of whack, then you will need to force your refresh rate to 60Hz.<br><br>Thu, 04 Oct 2007 15:34:19 GMTTechSupporthttp://forums.vuzix.com/Topic73-2-1.aspxAny graphics card that can do 1024x768 at 60Hz should work.

I have reviewed the FAQ, and the Nvidia site, and teh VR920 manual, and still don't find a specific answer to my question. <br><br>I have an Alienware laptop. Two Nvidia 7900 512meg video cards in SLI. Windows XP latest. I want to run Hearts of Iron II. The game ONLY runs in 1024x768. It is not a flight sim or shooter. Rather a very engaging realtime WW2 sim. Can I use the VR920 glasses with my laptop to run this game? I don't care about the 3D. I want the ability to simulate a 60+ inch display. Will this work?<br><br>It would also be nice to have a specific list of which video cards are supported. Thank you for taking the time to read this. I do appreciate any replies. <br>Jon MTue, 02 Oct 2007 19:08:03 GMTJonMhttp://forums.vuzix.com/Topic73-2-1.aspx@3D: Hey, no problem. It's assumed that when you are at a website that reviews devices, they've actually seen the device at some point. One of our first customers wrote a great review at his website, which you can find at http://cybereality.com/sections/vr920_review.htm.Thu, 23 Aug 2007 09:10:48 GMTTechSupporthttp://forums.vuzix.com/Topic73-2-1.aspxSorry Vuzix (TechSupport), I did not know this information was wrong and from the reply you posted I think I did read iton the same site you talk about. <br><br>I just thought they knew the product's they review but.....YOU CAN'T BELIEVE EVERYTHING YOU READ...:):D:PWed, 22 Aug 2007 17:51:59 GMT3dhttp://forums.vuzix.com/Topic73-2-1.aspxThanks guys. I'm not really interested in using the VR920 for gaming, but am looking for something to complement a UMPC. Most of the current generation have a native resolution of 800x480 and interpolate up to 1024x768. I have a Z800, but it is too bulky, even if it is 800x600 native.</P><P>If VR920 at 800x600 is good for text then I'll keep it on my wish list, but I really want 1024x768 text. Head tracking is a no-op for me (value add is minimal).Wed, 22 Aug 2007 07:52:43 GMTGen-Mhttp://forums.vuzix.com/Topic73-2-1.aspx@3D:<br><br>Not exactly. I've seen this information before, most namely on a review site that clearly had no clue what it was talking about, since it said that our headtracking moved on the x, y, and z axis, and gave no roll, pitch, or yaw functionality. There were several other mind-blisteringly inaccurate statistics on that site, and one of the things they said was that we drop the color depth. Since it is clear they've never seen a VR920, and that they made up all the information they posted, this is not accurate. However, it sounds good enough, so it has been repeated a few times.<br><br>We don't effect the color depth with our scaling method. While it is true that our color depth is lower than you probably have on your desktop monitor, it stays the same no matter the resolution. Like Adam was saying, we sort of average out pixels in such a way that the larger image fits. It works great on images, not so great on text. If you are going to be doing a text intensive activity, I always recommend doing it at 800x600 for the greatest clarity, since most text at 1024x768 is significantly blurred.Wed, 22 Aug 2007 06:21:30 GMTTechSupporthttp://forums.vuzix.com/Topic73-2-1.aspxI thought I read that when in 1024*768 mode the VR920 used a scaling method that droped color to a lower bit depth like from 24 bit to 16 bit so that it could show more detail or have a sharper picture with just a little loss of color depth . Is this right ?Thu, 16 Aug 2007 17:28:57 GMT3dhttp://forums.vuzix.com/Topic73-2-1.aspxCool! That'll teach me to be a know-it-all about image scaling. ;)Thu, 16 Aug 2007 16:38:47 GMTtentacleshttp://forums.vuzix.com/Topic73-2-1.aspxPS</P><P>I thought I'd add, there are many methods of scaling out there. You can throw away pixels, OR, you can manufacture new pixels that are a function of the old pixels. We prefer the latter method, it creates a superior image when compared with just tossing out data.</P><P>:)</P><P>AdamThu, 16 Aug 2007 14:00:11 GMTATravershttp://forums.vuzix.com/Topic73-2-1.aspxCorrect, we use a scaling engine :)Thu, 16 Aug 2007 13:45:13 GMTATravershttp://forums.vuzix.com/Topic73-2-1.aspxIt just scales it down. I mean, there's only one way to do it, right? There are different methods of interpolation for scaling up, but going the other way you just toss out some of the data and cram it on there.<br><br>It just means that stuff will appear smaller, but there won't be any more detail. For instance, you can use it in a game so that the HUD doesn't take up so much space (since most games are too stupid to allow interface scaling). The downside of course is that something like very small text will be illegible because the resolution simply isn't there to render it in detail. <br><br>If you want to see what it looks like, take a screenshot in 1024x768 and then go into photoshop or something and scale it down to 640x480. That's what the VR920 will be displaying.Thu, 16 Aug 2007 11:30:15 GMTtentacleshttp://forums.vuzix.com/Topic73-2-1.aspxIn this review (<A href="http://www.cybereality.com/trackback.php?section=vr920_review">http://www.cybereality.com/trackback.php?section=vr920_review</A>) he thinks the VR920 does a good job in games at 1024*768and says heuses Windows at800*600 with no problem on the VR920.
