Below is the 2nd batch unit review for the SMD ST1080P and is review by brantlew from MTBS3D forum which u can refer to the link for more detail. Thanks
Alright, alright... here's just a little bit
I don't sense that there are manufacturing defects with my unit, but the fundamental design issues that other have reported are present.
Light bleed on the sides - yes
Focus problems along the top and especially the top corners - yes
Some internal transient lens reflections - yes
Some type of optical artifact on the bottom corners (reported as looking like screen projector on AVS Forums) - yes
Color aberration during high speed eye shifts - yes
But I was prepared for all of that so it did not really disappoint me much. The blurry corner is the thing I dislike the most. 85% of the screen looks fantastic however. Colors are nice. Text is sharp. I actually find that 1080 is too high of a resolution. I am working right now, so I did some coding in Dev Studio for a bit just to see if it could be used as a desktop. I am sensitive to small text, so I bumped my resolution down to 720 and that was more comfortable. The text was clear at 1080 but I personally don't like it that small.
The 3D effect is muted as others have reported but I only played with it for 5 minutes. I popped in SkyRim for 5 minutes as well and it looks great. This is really what this unit is for - immersive gaming. Unlike my other crap HMD that I have to memorize the menu systems because it is so blurry, I had no problem what-so-ever navigating menu systems. An of course in game - stuff like blurry corners and light bleed are a non-issue.
So my initial impressions are pretty good. I'll be doing a lot more testing tonight - plus the thing that I think will matter the most: head tracking.
