The announcement of the new Apple Pro Display XDR was greeted with stunned enthusiasm during the WWDC 2019 keynote in June. But the stunning wasn't done. A few moments later the crowd learned the.

Matt Elliott April 15, 2014 12:17 p.m. Apple's new Pro Display XDR is the first own-brand monitor that the company has produced since it discontinued the 27in Thunderbolt Display back in 2016.

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.
I'm offering these pages for free. In return, I just ask you torespect my copyright. Do not place these images on other websites orweb forums, and don't link directly to the images.
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...
More towards the end of this page series are the inversion test,the response-time test, and the various viewing-angle tests. Thesetests can reveal monitor properties that cannot be changed.

After isolating an issue on your Mac to a possible hardware issue, you can use Apple Diagnostics to help determine which hardware component might be causing the issue. Apple Diagnostics also suggests solutions and helps you contact Apple Support for assistance.
If your Mac was introduced before June 2013, it uses Apple Hardware Test instead.
If you choose to get more information, your Mac starts up from macOS Recovery and displays a web page asking you to choose your country or region.
