Gta V Display Calibration
Nikita Desjardins
Welcome to the Lagom LCD monitor test pages. With the test imageson these pages, you can easily adjust the settings of your monitor toget the best possible picture quality. Additionally, there are anumber of test images that can help you to judge the image quality ofa monitor. You can check the images on this webpage or put them on ausb stick and try them in the computer store like I did when I createdthese test patterns. These test images are much more revealingregarding monitor shortcomings than ordinary photographs.
With the first few test images, you can calibrate your monitor by adjustingthe brightness, contrast, clock/phase, sharpness, and gamma settings of themonitor. I recommend to go through them in the order they are presented. Ifyou use this page in a shop, don't assume that the contrast and othersettings are at reasonable values before making a judgement. The images arebest viewed in a dim or dark environment and in full-screen mode. In mostbrowsers, F11 switches to full-screen mode. If switching off the lights isnot possible, try using a piece of cardboard to shield environmental light.
If you have any kind of color management system active in your operating system or video-card driver, then disable that first. First make adjustmentsto the monitor settings to let it behave as close to the ideal as possible,and only after that you can use the color management to compensate for anysmall deviations that remain.
Actually, calibration is not really the correct term. Calibratinga monitor would mean that you measure the response of the monitor and thencompensate for non-ideal behavior elsewhere, for example in the video-carddriver. Here, you are supposed to change the properties of the monitoritself to let it approach the ideal better. But then, who cares whether youcall it monitor adjustment or monitor calibration...

If you would like to support the development of, technical assistance with, and continued availability of DisplayCAL and ArgyllCMS, please consider a financial contribution.As DisplayCAL wouldn't be useful without ArgyllCMS, all contributions received for DisplayCAL will be split between both projects.
For light personal non-commercial use, a one-time contribution may be appropriate.If you're using DisplayCAL professionally, an annual or monthly contribution would make a great deal of difference in ensuring that both projects continue to be available.
If you have decided to contribute (many thanks!), but you'd like to give to ArgyllCMS directly on your own behalf (visit argyllcms.com and scroll down a bit to get to its contribution links), please leave a message on your DisplayCAL contribution if contributing to both projects. Please note that if your contribution should be put towards adding a certain feature in ArgyllCMS, like support for a specific instrument, it will be more appropriate and efficient to contribute to ArgyllCMS only, and directly.
If you'd like to measure color on the go, you may also be interested in ArgyllPRO ColorMeter by Graeme Gill, author of ArgyllCMS. Available for Android from the Google Play store. Check out the 2 Minute Overview + Guided Tour Video.
DisplayCAL (formerly known as dispcalGUI) is a display calibration and profiling solution with a focus on accuracy and versatility (in fact, the author is of the honest opinion it may be the most accurate and versatile ICC compatible display profiling solution available anywhere). At its core it relies on ArgyllCMS, an advanced open source color management system, to take measurements, create calibrations and profiles, and for a variety of other advanced color related tasks.
Calibrate and characterize your display devices using one of many supported measurement instruments, with support for multi-display setups and a variety of available options for advanced users, such as verification and reporting functionality to evaluate ICC profiles and display devices, creating video 3D LUTs, as well as optional CIECAM02 gamut mapping to take into account varying viewing conditions. Other features include:

DisplayCAL is written in Python and uses the 3rd-party packages NumPy, wxPython (GUI[4] toolkit), Certifi, PyGObject or dbus-python for Linux (required for Wayland support with colord), as well as Python extensions for Windows, comtypes and the Python WMI module to provide Windows-specific functionality. Other minor dependencies include faulthandler, psutil, PyChromecast and pyglet (macOS/Windows) or libSDL2 (Linux). It makes extensive use of and depends on functionality provided by ArgyllCMS. The build system to create standalone executables additionally uses py2app on Mac OS X or py2exe on Windows. All of these software packages are by their respective authors.
Packages made for older distributions may work on newer distributions as long as nothing substantial has changed (i.e. Python version). Also there are several distributions out there that are based on one in the above list (e.g. Linux Mint which is based on Ubuntu). This means that packages for that base distribution should also work on derivatives, you just need to know which version the derivative is based upon and pick your download accordingly.
If you want to verify the integrity of the downloaded file, compare its SHA-256 checksum to that of the respective entry in the SHA-256 checksum list. To obtain the checksum of the downloaded file, run the following command in Terminal: shasum -a 256 /Users/Your Username/Downloads/DisplayCAL-3.8.9.3.pkg
If you want to verify the integrity of the downloaded file, compare its SHA-256 checksum to that of the respective entry in the SHA-256 checksum list (case does not matter). To obtain the checksum of the downloaded file, run the following command in a Windows PowerShell command prompt: get-filehash -a sha256 C:\Users\Your Username\Downloads\DisplayCAL-3.8.9.3-[Setup.exewin32.zip]
Alternatively, if you don't mind trying out development code, browse the SVN[8] repository of the latest development version (or do a full checkout using svn checkout svn://svn.code.sf.net/p/dispcalgui/code/trunk displaycal). But please note that the development code might contain bugs or not run at all, or only on some platform(s). Use at your own risk.
Also there are currently (2014-05-20) five instruments (or rather, packages) under the ColorMunki brand, two of which are spectrometers, and three are colorimeters (not all of them being recent offerings, but you should be able to find them used in case they are no longer sold new):
After satisfying all additional requirements for using the source code, you can simply run any of the included .pyw files from a terminal, e.g. python2 DisplayCAL.pyw, or install the software so you can access it via your desktop's application menu with python2 setup.py install. Run python2 setup.py --help to view available options.
If the pre-compiled extension module that is included in the sources does not work for you (in that case you'll notice that the movable measurement window's size does not closely match the size of the borderless window generated by ArgyllCMS during display measurements) or you want to re-build it unconditionally, run python2 setup.py build_ext -i to re-build it from scratch (you need to satisfy the requirements for compiling the C extension module first).
If you are using Windows 8, 8.1, or 10, you need to disable driver signature enforcement before you can install the driver.If Secure Boot is enabled in the UEFI[12] setup, you need to disable it first. Refer to your mainboard or firmware manual how to go about this. Usually entering the firmware setup requires holding the DEL key when the system starts booting.
A lot of distributions allow easy installation of packages via the graphical desktop, i.e. by double-clicking the package file's icon. Please consult your distribution's documentation if you are unsure how to install packages.
Starting with DisplayCAL 0.2.5b, you can use standard distutils/setuptools commands with setup.py to build, install, and create packages. sudo python setup.py install will compile the extension modules and do a standard installation. Run python setup.py --help or python setup.py --help-commands for more information. A few additional commands and options which are not part of distutils or setuptools (and thus do not appear in the help) are also available:
If your measurement device is a i1 Display 2, i1 Display Pro, ColorMunki Display, DTP94, Spyder2/3/4/5, you'll want to import the colorimeter corrections that are part of the vendor software packages, which can be used to better match the instrument to a particular type of display. Note: The full range of measurement modes for the Spyder4/5 are also only available if they are imported from the Spyder4/5 software.
These instruments greatly reduce the amount of work needed to match them to a display because they contain the spectral sensitivities of their filters in hardware, so only a spectrometer reading of the display is needed to create the correction (in contrast to matching other colorimeters to a display, which needs two readings: One with a spectrometer and one with the colorimeter).
That means anyone with a particular screen and a spectrometer can create a special Colorimeter Calibration Spectral Set (.ccss) file of that screen for use with those colorimeters, without needing to actually have access to the colorimeter itself.
