This is a follow-up to my article on HDTV screen resolution vs a persons ability to perceive any advantage. Before the link to the test pattern, I want to make it clear that the results vary greatly with the content. With an anti-aliased image (i.e. a photograph of a person with many color gradients), it would be much more difficult to detect a single pixel. With a non-anti-aliased image (solid single-color lines), pixels become much more apparent. To allow everyone to conduct a simple test for themselves, I created a sample a page that is half-way in between the scenarios described above. It is aRead More →

There are two different factors to determine how close a viewer should sit to the screen of their home theater (field-of-view and picture resolution). To choose a proper distance, it is necessary to understand the impacts of both, and understand when trade-offs occur. There are multiple ideal seating distances depending on the equipment and the preferences of the viewer. Here the details of these two separate factors: Field-of-View based viewing distances: The THX and SMPTE specifications are based on a field-of-view being a certain width or wider, meaning that all seats must be closer than a certain distance to the screen. In general, the widerRead More →

Recommended Seating Distances and Resolution benefits (small)I’ve read various articles debating the importance of the 1080p. I want to set the record straight once and for all: if you are serious about properly setting-up your viewing room, you will definitely benefit from 1080p (and even 1440p.) Why? Because the 1080p resolution is the first to deliver enough detail to your eyeball when you are seated at the proper distance from the screen. But don’t just take my word for it, read on for the proof.

There are a few obvious factors to being able to detect resolution differences: the resolution of the screen, the size of the screen, and the viewing distance. To be able to detect differences between resolutions, the screen must be large enough and you must sit close enough. So the question becomes “How do I know if need a higher resolution or not?”. Here is your answer.

I just read the The case against 1080p article on cnet by David Carnoy. I think the article offers pretty decent commentary on side-by-side viewing comparisons of 720p and 1080p flat panels. However, the article states that it “isn’t the most scientific test” and that “At larger screen sizes, the differences might become somewhat more apparent, especially if you sit close to the screen.” Kudos to the author for pointing these out; I’ve addressed these issues in this post, which explains when and why 1080p (and 1440p) are important. I’m particularly impressed that the cnet article references the Imaging Science Foundation (ISF), stating the theRead More →
