4K and 5K Display Buyer's Guide for Macs

4K displays are becoming increasingly popular as they come down in prices, and even some 5K displays have been released over the past year, but there are lots of variables to consider before purchasing one for your Mac. This buyer's guide will help you determine the ideal 4K or 5K display for your MacBook, MacBook Air, MacBook Pro, iMac, Mac Pro or Mac mini, based on compatibility, price, display technologies and

DisplayPort 1.4 to Use 'Lossless' Compression for Higher-Quality 8K Video Over USB-C

The Video Electronics Standards Association yesterday formally announced its new DisplayPort 1.4 standard, setting the stage for improved video quality and color for external display connections over both DisplayPort and USB-C connectors. Rather than an increase in actual bandwidth, the improvements in DisplayPort 1.4 come due to improved compression, taking advantage of VESA's new Display Stream Compression 1.2 standard to support High Dynamic Range (HDR) video up to either 8K resolution at 60 Hz or 4K resolution at 120 Hz.DSC version 1.2 transport enables up to 3:1 compression ratio and has been deemed, through VESA membership testing, to be visually lossless. Together with other new capabilities, this makes the latest version of DP ideally suited for implementation in high-end electronic products demanding premier sound and image quality. In addition to video-related improvements, DisplayPort 1.4 also expands audio capabilities with support for 32 channels, 1536kHz sample rates, and broader support for "all known" audio formats. The approval of DisplayPort 1.4 comes even though consumers are still awaiting the arrival of devices supporting the previous DisplayPort 1.3 standard. Intel had been expected to support DisplayPort 1.3 in its current Skylake generation of chips, but the company instead opted to offer dual DisplayPort 1.2 support. As we detailed earlier this year, the lack of DisplayPort 1.3 support in Skylake could lead Apple to hold off on releasing a new 5K Thunderbolt Display until next year when chips supporting the standard become available.

DisplayPort Standard with 8K Support for Notebooks and All-in-Ones Heading for Mid-2016 Launch

The Video Electronics Standards Association (VESA) yesterday announced that it has officially published the Embedded DisplayPort (eDP) Standard version 1.4b, which brings the previous 1.4a iteration into the final stages of production-ready status for future notebook and all-in-one desktop displays. This final revision of the eDP 1.4 standard includes a few "key protocol refinements and clarifications" to ensure ease-of-integration for partners supporting it and an overall lower bill of materials costs to its implementation. The eDP 1.4 standard was announced two years ago, with an improved eDP 1.4a standard arriving earlier this year setting the stage for future 8K support on notebooks and all-in-one desktop computers. The association promises that GPUs and CPUs that run the DisplayPort 1.3 standard for external display connectivity with 5K support will also be able to eDP 1.4b for internal uses. DisplayPort 1.3 support is, however, still only in the early stages, with Intel's latest Skylake chips not including it. According to Bill Lempesis, executive director at VESA, “Since its introduction in 2008, eDP has become a central system element within the mobile computing market space. The standard has continued to retain its lead in display performance, supporting embedded panels with resolutions as high as 8K. We look forward to seeing systems incorporating the finalized standard come to fruition next year, broadening the number of consumers receiving clear, crisp visual information delivered by eDP 1.4 on their laptops, tablets, all-in-one PCs and possibly even

2015 MacBook Air Can Drive 4K Displays at 60Hz

The recently refreshed 2015 MacBook Air can drive 4K external displays at a refresh rate of 60Hz, as confirmed by Ars Technica. The report claims that Intel's new Broadwell processors with integrated Intel HD Graphics 6000 support 4K output at 60Hz using a DisplayPort 1.2 cable, whereas previous-generation notebooks with Haswell processors were limited to lower resolutions at 30Hz. Apple's tech specs page for the new MacBook Air lists the notebook as capable of supporting one external display at up to 2,560×1,600 pixels, which clearly is not the case. Apple may be electing not to advertise 4K support for the new MacBook Air on purpose, however, as performance can still be somewhat laggy or jerky and the company has a shortlist of supported displays and configurations."Given that the Air is using one of Intel’s integrated GPUs, general OS X user interface performance isn’t too bad while driving the Air’s internal display alongside the 4K display. Dropped frames are clearly visible when entering into Full Screen mode or using Mission Control, and of course you’ll never want to try playing games or doing heavy 3D work at native resolution. But things are more than smooth enough for desktop use."The new Thunderbolt 2 port included on the refreshed MacBook Air and MacBook Pro is compatible with the DisplayPort 1.2 spec, meaning that Single-Stream Transport is possible using one cable. Meanwhile, 4K over HDMI remains restricted to a 24Hz refresh rate due to the limitations of the current 1.4 spec. Multi-Stream Transport should also be possible using DisplayPort 1.2,

New DisplayPort 1.4a Standard Points to 8K Notebook and All-in-One Desktop Displays in 2016

The Video Electronics Standard Association (VESA) yesterday announced a new Embedded DisplayPort Standard, version 1.4a, that the association claims "enables a higher video data transfer rate for increased panel resolution, greater color depth and higher refresh rates." Along with other upgrades, the new standard will be able to take advantage of more advanced GPU video performance and display technologies, meaning a wider range of computing devices - laptops and all-in-one PCs like the iMac in particular - will be able to produce 8K content sometime next year. The new standard is for "embedded" panels with the ability to produce up to 8K quality display images, meaning eDP 1.4a won't work with external displays. The current DisplayPort standard is 1.2a, with VESA having announced the next-generation 1.3 standard with 5K support last September. Full support of DisplayPort 1.3 will, however, need to wait until Intel releases its next-generation Skylake chips late this year or early next year. Apple's current 5K Retina iMac uses a custom solution to manage its 5120 x 2880 display, and 8K displays supported under the future 1.4a standard would come in at 7680 x 4320 pixels. These higher-resolution displays at 8K should result in a more power-hungry machine, but VESA claims its new Multi-SST Operation will support a Segmented Panel Display feature, bringing lighter, lower-cost display architecture to the new eDP standard. According to Vice President Bong-Hyun You of Samsung Display Co., Ltd., this new strategy can "reduce panel thickness, reduce power draw, and
