A display filter tries to change an image so that it looks like it's on a display created with different technology.
PC Monitor Filters
Four scanlines are overlaid on top of each pixel horizontally and 2 vertically. The intensity of the shading is adjustable.
Filter with a very slight blur similar to CRT monitors at 60Hz and below.
Display FX for Custom Display Filters
Custom display filters can be created by stretching the input with a scaling filter and then applying display FX filters overtop of it.
Below is a list of the display FX filters provided by Sclender.
Blurs the image horizontally, vertically, and diagonally to increase color depth and anti-alias. Can also be applied automatically to the output prior to presentation.
Blurs the image horizontally, vertically, and diagonally to increase color depth and anti-alias. The output is less artificial and usually clearer than bilinear, but requires more power.
Attempts to replicates the interaction of excited phosphors by brightening pixels relative to the brightness of their neighbors.
Horizontally blurs the image, increasing its color depth while decreasing jaggedness at cost of sharpness.
Like Blur Left, but is adjustable. The ability to adjust comes at cost of speed.
Vertically blurs the image, increasing its color depth while decreasing jaggedness at cost of sharpness.
Attempts to replicate the behavior of by aggressively blurring of the image horizontally... the effect is similar to putting the sharpness setting as low as it can go on a SD television. Substantially increases color depth and anti-aliases lines and edges, but at cost of sharpness. Can be difficult on the eyes after a while.
Attempts to replicate the physics of a cathode ray striking the inside of a glass tube. Higher fidelity than horizontal/vertical blurring alone, but requires more power.
Shades every other row of pixels in the image. Appropriate for simulating television picture of the 60s, 70s, and early 80s, and some handheld LCD displays and arcade cabinet displays.
Shades every other column of pixels in the image. Appropriate for simulating television picture of the 90s, and some handheld LCD displays and arcade cabinet displays.
Increases the contrast between brighter and darker colors to refine edges and increase color depth.
