Toshiba Qosmio F755-3D290: Glasses-Free 3D?
by Dustin Sklavos on November 23, 2011 1:10 AM ESTGaming Performance
Without 3D Vision being functional on the Toshiba Qosmio F755, we're reduced to the basics. I elected not to run any of our tests at the notebook's native 1080p resolution because, frankly, the GeForce GT 540M has consistently proven not to be powerful enough to handle it. You'll see it even struggles in our "High" benchmark when we jack up the resolution to 1600x900, high enough that the limited memory bandwidth starts to be a real burden.
In our medium suite, the F755 is able to at least put in a decent showing, with only the Acer TimelineX 3830TG having trouble keeping pace (due to both the i5-2410M and the fact that the notebook throttles the processor pretty heavily). These are really the settings the GT 540M belongs at. Note how rarely the 540M breaks 60fps even at these settings, basically the minimum for a decent 3D Vision experience. Even if Toshiba and NVIDIA do get it working on the F755, it's likely not to be very useful.
Bump the settings up to "High" and things take a turn. Now the GT 540M has a much harder time keeping up, and it's clear it wasn't never meant to run at a resolution this high, let alone the F755's native 1080p. It's just not powerful enough; the GTX 560M is a far better solution and still able to fit into a 15.6" chassis, even though it adds a bit of bulk.

Thinking that's supposed to be a laptop model?

looks like there are some serious bugs with the software stack...but technically this is one of the most advanced glass-free 3D screen out there, and should provide much more natural & comfortable 3D effect on real 3D content, which could easily beat anything on the consumer market, even the professional market.
it's a pity that it isn't functioning properly in the test.

I don't know why anyone feels they need an IPS laptop unless they're doing graphics work that requires full color accuracy. The best TN desktop screens provide very good image quality - much better than what was available 2 years ago, and viewing angles are usually less of an issue with laptops.Some laptop screens are good. The Dell 15" that's currently out has an RGB+ option and it looks amazing. The Alienware screens look good if you're OK with glossy.

Drab washed out screens with a really obvious change of color depending on how you hold it is good image quality?The screen quality is one of the top reasons I just ordered a Thinkpad X220 - IPS screens are just miles above the garbage TN panels everyone is using now (except Apple).
The one thing you use more than anything on a laptop is the screen (more than even the keyboard) so why would you not want a good one?

How does the 3D fair in regards to eye strain? I have an Evo 3D phone and it's horrible to look at in 3D mode. Myself and everyone I've shared it with has said "that's cool looking but, it hurts my eyes" The videos are better than pictures, but I much prefer the way active lense 3D treats my eyes.People talk about being uncomfortable with glasses on for 3D content, in my experience the glasses are much better than the glasses-free version.

the screen on this toshiba laptop shall give much less eye strain than other glass-free 3D screens, and also less than the ones with glasses, if it is functioning.because this screen has an array of adjustable lenticular micro lens on top of the LCD screen, and it will actively adjust the light path to fit with your view point, which is captured by camera in real time.
the down side is it can only be used by one people, since the screen cannot fit with 2 pair of eyes simultaneously. what's why this technology is used on laptop prior than TV
