2005 Aquos Models - Technophobes please


Standard Member

Hope the title tweaks somebody's interest.

The new Sharp Aquos models for 2005 replacing the GA3/4's look like being full HDTV devices with a resolution of 1920x1080 as per the LC-45GD1E.

My question is, as this doubles the resolution from 1 to 2 megapixels compared to the GA3/4's and in theory should improve the (still) picture quality, does this also hold true for a TV image, especially a fast moving one?

Doesn't doubling the resolution also double the processing load and in particular, the screen refresh data. If so, is it necessary to speed up the refresh rate which is ok on the Sharp but not brilliant and how does the LC-45GD1E address this problem if it is one?

Is this a case of the advantages of the higher resolution being cancelled out by the greater time to process the additional data?

Looking forward to the technical explanation.



For video, refresh rate is typically 50 or 60Hz irrespective of the panel resolution. Yes the drive electronics has to clock faster - but that's all taken care of in the panel. With careful design a single link DVI interface can take 1920 x 1080p.

SD TV image will look about the same on 1368x768 vs 1920x1080 - since the panel res is already way over SD TV res of 720x576.

IMHO there's no benefit in 1920x1080 for screen sizes below 42" at normal 'living room' viewing distances (6-10ft) - since your eye can't actually resolve the extra detail. However, if you can afford 42"+ then 1080 looks fantastic :smashin:
