At last, there should no problem to switch to 16:9 modes on this PJ except in 3D mode. Of course, maybe stepping into 2011, we’ll launch 1080P 3D supported projector soon based on IC provider’s product roadmap accordingly. If we try to search the current 3D contents (up to 720P), you’ll figure out this is indeed a 3D technology limitation as now. Of course, double IC layout can solve this problem but related S/W and other side effects haven’t been solved yet.
Owing to 3D contents will be separated into double frame, the current bandwidth will be limited. Regarding to aspect ratio this issue, we may have a deep thinking on why the native resolution on 3D mode is 1280x720 (16:10) but 1280x800 (16:9) this normal timing instead? As the main chip from TI, the current market scalar IC manufacturer hasn’t developed to 1080P caused by bandwidth limitation. In the Ait control panel, i can enable GPU scaling and set it to centred timing which does enable me to get a 16:9 aspect ratio, but then i am unable to select the 3D 120Hz modes in any resolution. Projector menu only allows switching between 16:10 and 4:3 options, there are no 16:9 options. There is absolutely no way to change it to 16:9 aspect ratios. In the native and advertised 3D mode of 1280x720p at 120Hz, the image is always stretched to fit a 16:10 profile. Hope the customer could understand and usage as a LCD type PJ when in 3D mode, thank you!Ģ. However, this is the current technology limitation on DLP type projector in 3D application from TI. Yes, one of the advantages for DLP type PJ is no need to turn off the indoor light comprising with LCD type PJ. As a result of that, the brightness will be reduced 25% than standard mode. The IC chipset of current DLP link type 3D projector on the market were adopt the same standard spec IC provided from Texas Instrument (TI), and in order to sync the 3D content stream in between graphic and PJ side will been taken along with 90 degree (90/360) of white + cyan colours picking from colour wheel. Technically, there is nothing preventing a brightest possible picture! Why is this? It's certainly not what I expected from a 3000 Lumen projector. 3D glasses always make the image dark as it is, so if anything, the image should be as bright as possible to try and compensate.
DLP Link only sends out small sync pulses in between each frame, it should not have a negative impact on brightness. In S3D modes (at 120Hz), the image is very much darker compared to any other mode. Sorry for the late reply, and please see my feedback for inquiry 1 & 2:ġ. So, I finally receive a reply from the Viewsonic Engineers:
