Nvidia GeForce 3D Vision vs eDimensional 3D Vision

June 22nd, 2009 · 1 Comment · GeForce 3D Vision


If you remember I’ve written that the shutter glasses designed by Nvidia for the GeForce 3D Vision are way looking much better than previous such products, but here I made some pictures so you can even see that for yourself. In the left of the images you can see the glasses from Nvidia and on the right are eDimensional’s wireless 3D Vision glasses, the difference in design is clearly visible…


Besides being more good-looking Nvidia’s glasses are also more comfortable and adjustable to the needs of different users, not that Edimenstional’s glasses don’t have such ideas embedded, but their design is still not that good. By making shutter glasses you need to design them so that they not only don’t look weird, but also to be comfortable even when wearing them for longer periods of time…


Not that the shutters on eDimensional’s glasses are almost square in form, where as the glasses from Nvidia are wider and this is because of big difference in time when the products were designed and first released on market. eDimensional’s 3D Vision glasses are quite old product, as far as I remember released 5 or even more years ago when the CRT displays with aspect ration of 4:3 or 5:4 were used almost everywhere. But now most of the new displays are widescreen with aspect of 16:10 and 16:9 so having wider shutters is not only good, but is actually a requirement in order to have the wide filed of view needed for the new LCD monitors. Another big difference is that eDimensional’s glasses use 2 lithium batteries for power that are not rechargeable and you have to replace them from time to time, although they last longer than the rechargeable battery available in Nvidia’s glasses. Anyway with up to 40 hours on a single charge and an easy and widely used mini USB connection for recharging there is not much to complain about Nvidia’s 3D Vision glasses.

Here I have not provided pictures of the IR transmitters of the two types of wireless shutter glasses, but you should know that eDimensional’s solution does not rely on USB connection and actually requires you to connect it between your video card’s output and the monitor you are using. And you can already guess that it utilizes an analogue DSUB15 video connector in order to do that and the drivers are supposed to do everything else. Now, when talking about drivers, eDimensional had a bit of an advantage, becuse they used their own drivers that were compatible with both ATI and Nvidia video cards, although the glasses also worked with Nvidia’s old stereo drivers. Currently eDimensional’s drivers are quite out of date and not very usable, and the newer stereo drivers from Nvidia no longer support them (along with many other older devices!). If you own eDimensional 3D Vision glasses or any other shutter glasses you may try to run them with IZ3D’s driver, but the success rate depends on a lot of factors and the results will still not be as good as when using Nvidia’s 3D Vision. Not to mention the fact that if you intend to use the IZ3D driver (besides just quick testing) with something else than their 3D displays you’ll have to buy a license and the shutter glasses support that is currently available is still not very good, so don’t get your hopes too high.

ViewSonic VX2265wm FuHzion Monitor Specifications

June 16th, 2009 · No Comments · GeForce 3D Vision


ViewSonic VX2265wm FuHzion is the 120 Hertz (120 fps) monitor that is being sold as a bundle with the GeForce 3D Vision glasses in the American market and as a standalone LCD display of course. Even if not using it in 3D stereo mode you can still set the monitor at 120 Hz refresh rate and have a better and more responsive LCD display than all other models currently available on the market (probably besides the similar Samsung 2233RZ). But lets get to the technical specifications of the display in order to see what it actually offers in both 2D mode and in 3D when used in conjunction with 3D Vision glasses.

ViewSonic VX2265wm FuHzion is a 22-inch monitor with widescreen aspect ratio of 16:10 (not the recently popular 16:9) and resolution of 1680×1050 (again not Full HD as the new 16:9 22″ displays already available). The display is using a TN panel with maximum brightness level of 300 cd/m2 (very important when used in 3D mode), contrast ratio of 1000:1 (typical) and response time of up to 3-5 milliseconds (3ms for gray-to-gray and 5ms for black-to-white transitions). The viewing angles are quite good at up to 170º horizontal and 150º vertical at contrast ratio of more than 10:1 which you’ll notice when you see the display, and I should note that there is no glossy and mirror-like filter in front of the display, but a matte one which is probably better when used with 3D Vision. The display has only Dual-link DVI-D display port for connection to a PC and you need Dual-link cable in order to provide 120 Hz refresh rate over the DVI interface at 1680×1050 resolution, otherwise you’ll probably be limited to 60 Hz over a single-link cable. One thing that differentiates ViewSonic VX2265wm from Samsung’s solution (I guess they both use Samsung-made panels) is the built-in 2x 2W stereo speakers in this monitor and the support they have for SRS WOW HD sound technology, otherwise the two monitors are almost alike (apart from their external design of course). An when we are talking about external appearance maybe ViewSonic did a bit better job than Samsung in terms of design and also in terms of default height of the display which seems to be a bit higher here.
