Correctly said, you need to use a Sharpness Pattern to prevent edge enhancement (halo/ringing effect) or soft contouring (blurring of the image details).
Wrong Sharpness setting can hide the natural details from being displayed correctly.
You can check using a Sharpness Pattern some display settings like: Digital Reality Creation, Noise Reduction, MPEG Noise Reduction, Dot Noise Reduction, Noise Filtering, Detail Enhancer, Edge Enhancer, Super Resolution, Digital Clear View to see how they are affecting your image resolution.
You can see also how the Sony's Digital Reality Creation Manual Setting is interacting to the high frequency resolution lines and to find your best performance setting after trying some DCR's different values, and watch how many artifacts a wrong setting of your sharpness is introducing.

You may find interesting to test your display with this Advanced Sharpness Pattern that is available inside the Ted's LightSpace CMS Calibration Blu-Ray Disk
among with other 150 Color Reproduction Patterns
This Sharpness Pattern is not limited to typical Black/Gray/White Background that all current calibration disks are using but at 4-Step (25%, 50%, 75%,100%) of 7-Color Amplitude (Gray, Red, Green, Blue, Cyan, Magenta, Yellow) Background...
Better View - Part of the Advanced Sharpness Pattern
This Advanced Sharpness pattern is a real challenge for any display, it's will uncloak problems of you current sharpness control setting or from other enabled enhancements that were not visible before.
You can use it to verify your current sharpness setting value that you have set using a pattern generator or other calibration disk pattern since all other sharpness patterns available are based at grayscale lines/backgrounds only.
These multicolored backgrounds and shapes/lines combination will require to tweak your current setting to a different that is different setting from that you have already set based on other classic grayscale based sharpness pattern.
