The Sharpness control is one of the Basic Video Level settings found in every TV. It is also, alas, one of the settings most commonly abused by manufacturers trying to make their TVs stand out in a wall of competing TVs under garish store lighting! Indeed, TV Factory Default settings with Sharpness set WAY too high are commonplace -- a key facet of the justly-infamous Torch Mode settings foisted on new TV buyers. See my prior post on Extinguishing Torch Mode Settings for the others.
Excess Sharpness, in particular, produces the appearance of "false detail" in the image, which looks attractive on a casual glance (applause from the Marketing guys!). However, the REAL details of whatever you are watching are ACTUALLY being obscured!
In this post we'll discuss what the Sharpness adjustment does to your image, and how to set this control properly in your TV -- using a Calibration Disc.
We'll also discuss the problem of "Edge Enhancement"; damage akin to excess Sharpness ALREADY baked into the content you are watching! Read more
One of the biggest changes in a long time in Home Theater Video has been the recent introduction of High Dynamic Range (HDR) content, and equipment which can display it properly. HDR allows elements in scenes to be much MUCH brighter than with prior home video technologies (in comparison to other portions of the same image) -- excellent for sparks, glints, flashes, direct views of light sources, and details in bright objects such as clouds in bright sunlight. However, there is plenty of Standard Dynamic Range (SDR) content out there which you will still want to look its best. And the foundation for understanding what HDR brings to the table begins with an understanding of the proper rendering of SDR Video.
In my prior post on Blacker Than Black Video, I introduced the concept of the Headroom and Foot Room portions within the video encoding. The "Peak White" pixels found in SDR Video simply reflect the Headroom authored into that video content. Whereas HDR and SDR Video are quite similar in their treatment of Blacker Than Black pixels, they differ dramatically in how they handle these brightest pixels.
In this post we'll focus on setting up your TV to render Peak Whites properly whenever you are viewing SDR Video content: I.e., what you SHOULD see and what you SHOULDN'T see. So break out the sunscreen and get ready for a few Bright ideas! COOLNESS NOTE: Shades are optional. Read more
