If the TV displays it without converting it to checkerboard then you will get a benefit. Even though checkerboard accepts 1/2R input it does and excellent job of upscaling the contetn to full HD for each eye for display.
Here's what my tv's 3D menu says for the 640 is divided into features:
a. “Source Format” is the controls of the internal 3D adapter.
i. OFF is for no 3D even when you have a 3D signal.
ii. AUTOMATIC is for a 3D signal that matches the HDMI 1.4a standards for the Mandatory 3D signals.
iii. SIDE BY SIDE is for s-b-s 3D signals in 720p, 1080i, 1080p/24Hz, 1080p/30Hz, 1080p/60Hz signals that do not perfectly match the HDMI standards but are still available from cable boxes, satellite receivers and other sources. This is a manual setting. Also any 3D signal that would trigger the AUTOMATIC will override this setting.
iv. TOP/BOTTOM is for t-b signals in 720p or 1080p/24Hz that do not perfectly match the HDMI standards but may still be available from cable boxes, sat receivers, and other devices. This is a manual setting. Also any 3D signal that would trigger the AUTOMATIC will override this setting.
v. CHECKERBOARD is for 1080p/60Hz checkerboard 3D signals from external devices such as the external 3D adapter and several computer graphics cards/3D programs. This is a manual setting. Also any 3D signal that would trigger the AUTOMATIC will override this setting.
vi. 2D + DEPTH is to a 2D-to-3D converter of sorts. Gives standard 2D signals a 3D or depth quality and does require the glasses.
Here's what I could find about the resolution of 3d DLP's:
The 3D pixel count is half per eye in a DLP. But DLP is always 1920 x 1080 lines of resolution, 2D and 3D.
The checkerboard 3D format uses half of the pixels for the left eye view, and the remaining half of the pixels for the right eye view. Imagine a checkerboard. The red squares would contain the image for the left eye, and the black squares would contain the image for the right eye. Only the appropriate squares (red or black, not both) are flashed for each eye, leaving "holes" in the picture where the other colored squares would be.
Imagine a checkerboard with 1920 columns and 1080 rows. If you remove all the black squares or all the red squares, it still has the same amount of rows and columns. It's just that those rows and columns have holes at every other pixel location, as those pixels are used for the other eye's view.
Checkerboard maintains the 1920 x 1080 lines. It's not 1920 x 540 nor 960 x 1080. It is still 1920 x 1080. It just has 1920 x 1080 dotted lines. This is why it appears to be more than half resolution, and can compete with other formats.
Because each pixel is produced by a micro-mirror, and the mirrors change the image much faster than Plasma or LCD pixels, no ghosting occurs.
Given that information, would I be getting a better quality image with full SBS?
Also it sounds like full SBS takes more processing power than a regular 3D Blu-ray disc?
