Intel (and basically any AMD or Nvidia) GPUs can support frame-compatible 3D formats (side-by-side, interleaved, etc.) without much problem. However with Intel their GPUs are usually pretty weak (in comparison) so they don't run 3D games all the well. However Intel does have a brand called "InTru 3D" which basically means the chip (primarily 2nd-gen or newer CPUs with integrated graphics) can output over HDMI 1.4a. As far as I know, this is *only* for 3D Blu-Ray playback ( http://3dvision-blog.com/tag/intel-intru-3d/
), so for gaming you are still going to want to go with Nvidia or AMD.
With AMD (on the cheap end), you may want to look at their A8 Vision APU line, as that is listed as having HD3D support (meaning HDMI 1.4a frame-packing) [ http://www.amd.com/us/products/notebook ... eam.aspx#5
]. Though those are *not* high-end laptops, so you will still probably have trouble playing any newer games in 3D. If you want a gaming rig, look for something with an AMD 7XXXM series GPU. They mostly seem to support HD3D from what I can tell. Just go here: http://www.amd.com/us/products/notebook ... 7000m.aspx
and click on a specific GPU on the left, then hit specification in the middle. It will list AMD HD3D as a feature. If you have the money, something like the HP ENVY 17-3290NR looks pretty nice: http://www.newegg.com/Product/Product.a ... 6834158588
. You can also see a somewhat out-of-date list of other supports GPUs here: http://www.amd.com/US/PRODUCTS/TECHNOLO ... phics.aspx
With AMD you will have to rely on 3rd party software, but it works pretty well for the most part. So for gaming this means the DDD TriDef driver, which is nice (also cheap for AMD users). For 3D Blu-ray and videos you have lots of options, Stereoscopic Player, PowerDVD, etc. Some games have native 3D support like Deus Ex. So software is no problem.
With Nvidia they seem to have more options, but I would watch out. Officially they claim the following laptops and GPUs are supported: http://www.nvidia.com/object/3d-vision- ... ments.html
. However I bought a laptop on that list (Lenovo Y570) and it does not work AT ALL in 3D. One of the problems I have is that the Optimus technology messes up the 3D compatibility so I cannot output to a 3D screen. In fact, I can't even play 2D games very well on an external screen because the Nvidia card doesn't interface with the HDMI port (WTF!!!). It only works with the integrated Intel graphics, but that is so crappy anyway you can't even play games good. So watch out! If you do want to go with Nvidia, this seems like a nice choice and I was considering buying myself: TOSHIBA Satellite P755-3DV20 ( http://www.newegg.com/Product/Product.a ... 6834214410
). Otherwise you can look at the support laptop GPUs and just get a laptop up to spec but STAY AWAY from anything with integrated Intel (Optimus) as 3D doesn't work.
If you get a 3D laptop (w. a 3D screen) it should come with the software for free. If its an Nvidia laptop you should be able to use the 3DTV Play software for free. If it doesn't come with glasses (ie its just a normal laptop) then you are on your own to buy the software. Its pretty cheap though, so its not a huge deal.
If you have any specific models you are looking at please post a link and I can try to advice further.
