    LCD panel information

    I found this stickied on [H]ardOCP. Far too informative not to share. Thank you "wonkman" for the compilation.

    TFT Technology Breakdown and Model/Panel Index

    --------------------------------------------------------------------------------

    LCD Panel Technology Type and Characteristics

    TN film (Twisted Nematic)
    - low manufacturing/retail costs
    - restrictive viewing angles
    - fast pixel response times
    - dead pixels display white. Stuck pixels display RGB colors
    - lower contrast levels means blacks are not as dark as VA based panels
    - lower color reproduction

    IPS (In Plane Switching)
    - improved viewing angles over TN
    - very good color reproduction
    - slower pixel response times than TN
    - dead pixels display black
    - lower contrast levels means blacks are not as dark as VA based panels

    Super-IPS (S-IPS)
    - same as IPS except ...
    - likely best color reproduction of all TFT
    - less expensive to produce than IPS
    - improved pixel response

    VA (Vertical Alignment) Technologies

    MVA (Multidomain Vertical Alignment)
    - compromise between TN and IPS technologies
    - superior color reproduction over TN but not as good as IPS
    - very good viewing angles but less than IPS
    - higher contrast than TN or S-IPS means very good blacks
    - dead pixels are black
    - slower pixel response than TN or IPS
    - details can be lost when directly viewing dark areas

    Premium-MVA (P-MVA)
    - same as MVA except ...
    - "overdrive" technology increases pixel response but still slower than TN
    - may have slightly degraded color reproduction due to "overdrive" process
    PVA (Patterned VA)
    - same as MVA except ...
    - larger viewing angles
    - higher contrast levels means darkest blacks
    Super-PVA (S-PVA)
    - same as PVA except ...
    - “Magic Speed” (the Samsung equivalent to Overdrive) improves pixel response
    - slightly improved color reproduction
    - slightly improved viewing angles


    Purchasing Considerations

    TN Gamers
    Considered a "gamers" panel due to it's fast pixel response times which reduces trailing images know as "ghosting". However, this advantage has been reduced by new technologies to accelerate pixel response times in other panel types. Colors and contrast tend to be weak and blacks are not truly dark. Viewing angles are significantly limited. However, monitors based on this technology tend to be inexpensive.

    IPS / S-IPS Graphics Work or Web Browsing
    Considered to have the best color reproduction of all panel types, these panels are well suited for graphics work or web browsing. Pixel response time is also good but slower than the TN "gamers" panel. Contast and blacks are also less dark than VA panels but viewing angles are excellent.

    MVA / P-MVA / PVA / S-PVA Compromise for All-Around Use
    These panels are a compromise between the fast pixel response times of the TN panel and the excellent color reproduction of the IPS panels. Contrast and blacks are best of all the panel types. Viewing angles are similar but slightly inferior to IPS.

    Uh...yeah, 9 years later most computer technology has advanced while coming down in price. (notice date of original post...the year 2006)...
