3d Projector 1080p Resolution Explained
In this 3d Projector 1080p buyers guide you will learn on resolution rates and codes to check before you buy a 3D projector.
What is 1080p Means?
The 1080p, is referred to in marketing materials as “Full HD“, it means the projector is able to accept a 1080p (p=progressive) signal and display it with native resolution of at least 1080 lines. 1080p resolution is currently the digital standard for filming digital motion pictures.
To get an idea of the superiority of this 1080p resolution, consider the older versions of resolutions that are still around. You have the 1280 x 720 pixels (or the 720p) resolution, which is less than half the rate of the 1080p resolution specifications. The 1080p has the capability to upscale lower-resolution material to 1080p.
What Resolution To Look For In 3D Projectors?
Even when you search for 3D projector 1080p resolution, you come up with different results.. You probably are confused by the fact that 3D projectors show two different resolution rates… Native resolution and Compressed or Maximum resolution.
You need to check mostly the native resolution of the projector. This is the the actual, true, physical resolution of the projector. It’s the amount of pixels it has on it’s chips. No matter what they tell you down at the store.. The projector will never be able to display more actual pixels than it has on those panels or chips.
What is then the maximum resolution? This number is the maximum range of signal formats the projector is programed to recognize and display. If the incoming signal has a higher rate than the native resolution, the projector will compress it. If the incoming signal is lower than the native resolution, the projector will stretch it to fit the native resolution. This process is called scaling and in both cases it may affect the sharpness of the picture.
Part of the “image quality” question surrounding resolution rates has to do with your screen size relative to your viewing distance. If you are close to the screen then you will not feel the difference, as the room is larger the effect of the scaling will be more noticed.
For the most sharp images you better off to ignore the projector’s maximum resolution spec, and make sure to set your computer’s or Blu-ray output resolution to match the native resolution of the projector.
What Do The Resolution Codes Stand For?
When you buy a 3D projector you will see resolution codes, these are some time used to ‘confuse’ you up, regarding the real abilities of the projector. Remember to check the native resolution to see the real capabilities f the projector. Here are the main codes used to describe resolutions. (Bookmark this page for further use)
- Super Video Graphics Array – The term SVGA normally refers to a resolution of 800 × 600 pixels.
- Extended Graphics Array – XGA – is the most common appellation of the 1024×768 pixels
- Wide eXtended Graphics Array –WXGA – Is most commonly used to refer to a resolution of 1280×800 pixels
- Super eXtended Graphics Array – SXGA – Is referring to a standard monitor resolution of 1280×1024 pixels
All these resolutions are not HD ! They may have a compressed ability to read HD signals but they will have to scale the picture to their native resolution
The real HD is ATSC – 1080p – 1920 x 1080 progressive pixel scan.
This ATSC is high definition 1920 x 1080 progressive scan video format. Where a complete frame of video is delivered at either 60 or 24 frames per second.
Many 3D projectors with 1080p have lower resolution rates but can scale and compress and project 1080p resolution or even more.
3D Projector 1080p Conclusion
In this review we hope you learned some more on the key features to look for concerning the 3D projector 1080p resolutions. Before you buy a 3D projector, check it has a ‘3D ready’ label, this means the projector is able to decode at least one of the stereoscopic 3D transmission formats used by the the computer or the Blu-ray disk player.
There are at least four stereoscopic 3D transmission formats currently in wide use, called frame sequential, frame packing, side-by-side, and checkerboard. We will not review them here, but it is important you check the projector is supporting the transmission format you have or plan to buy.
