12/19/2023 0 Comments Switchresx 4k scaled to 1080p![]() ![]() ![]() This is the Haswell refresh of the rMBP15, and it remains the only portable Mac capable of driving a 4K panel at 60Hz over either of its two miniDP ports (HDMI is limited to 30Hz). By some I mean one: the 15-inch MacBook Pro with Retina Display from late 2013. Apple's Hi-DPI scaling and seamless integration across the ecosystem continues to be awesome.Īlong with expanded display support, some new Macs also get the ability to drive 4K panels at 60Hz. Note how little space the screenshot occupies. The screenshot open in Preview (screenshot within the screenshot) is a 2880 x 1800 screenshot, open at full size. ![]() At the highest scaled resolution setting the frame buffer is now over 20 megapixels (excluding the 5MP primary Retina Display), which is just insane. The full untouched PNG weighs in at 19.8MB from OS X and is a 6016 x 3384 image. For example, the screenshot below was taken with the UP2414Q set to its highest scaled resolution (3008 x 1692). The table above shows the frame buffer resolution in paratheses. The 24" 4K panel gains a new intermediate scaled mode of 2304 x 1296. This is similar to what happens on the rMBPs where text/UI elements appear as they would on a 1080p display, while images, videos and other similar objects appear as they would on a 3840 x 2160 display. There is no native 3840 x 2160 resolution exposed on the UP2414Q and by default OS X appears to want to run the panel in a 1080p Hi-DPI mode. Apple appears to have manually added a profile for the UP2414Q as its scaled resolutions are somewhat different from the 30" Sharp/ASUS 4K panels. The Dell UP2414Q, a 24" 3840 x 2160 display, is now properly supported by OS X and Macs that can drive it at its native resolution. ![]() With 10.9.3 Apple has not only broadly increased support for 4K displays, but also enabled 60Hz output to 4K displays on more systems. In the case of the 3200x1800 setting this means that the display is rendered offscreen at 6400x3600 which may cause performance issues when being driven with the Intel Iris graphics of a Macbook Pro with Retina Display or the entry level 21.5” iMac. All of these are handled the same way as on the Macbook Pro with Retina Display where the display is rendered offscreen at twice the selected vertical and horizontal resolution and then scaled down to the panel. Apple now gives the user options for display scaling which includes settings for a workspace that looks like 3200x1800, 2560x1440, 1920x1080, or 1280x720. In 10.9.3 Apple has greatly expanded the list of compatible 4K displays and has introduced scaling modes for those who prefer sharper UI elements over display real estate.Īnand took a look at the changes to 4K support in the first beta of 10.9.3. This made for poor usability on monitors like the Dell UP2414Q which is only 24” and has extremely small UI elements when running unscaled at its native resolution. Only a small group of monitors from ASUS and Sharp were supported for running at 3840x2160 with a 60Hz refresh rate, and the scaled display options that Apple introduced with the original Macbook Pro with Retina Display were unavailable. Prior to 10.9.3 the support for 4K displays on OS X was lacking. The most major improvement of the update is the improved 4K (3840x2160) display support on OS X. One of the most interesting things about the update is not in its content but in how Apple opened up their beta seed program to all users when it was traditionally reserved for those who are part of Apple’s developer program. The update comes after nine weeks of beta testing, each week with a new release. It would seem that the hardware is not an issue since it works after a reboot and works with my Dell Windows laptop.Today Apple released the long awaited OS X 10.9.3 update. However I know it is, as all that is needed is a reboot. I have tried Switchresx but hasn't helped since the Mac must be detecting that it is not possible. Wondering if there is anyway to force 60Hz since it has issues recognizing it. When I connect my Windows laptop to it, I don't have the same issue. It is random which of the monitors will revert to 30 Hz. After a little bit, with the mac going to sleep, one of the two monitors will revert to 30 Hz and cannot be set back to 60 Hz. My issue is that the refresh rate on one of the monitors will max out at 30 Hz. I have two 4k monitors connected via Display Port. Hello, I have an Intel MacBook pro connected to a Thunderbolt 4 docking station. ![]()
