In the "Default" setting four of the 4K video pixels at 5K resolution are used to generate a single display pixel with the 4K video then being scaled to a 2.5K display resolution with no discernible space between pixels. The only difference is in the resolution mode. VLC and other video players also play full res video.ĤK videos play the same in VLC and QTX on my system. However, the video is supposed to play full 4K (assuming you have a 4K or better screen). In retina resolution it reports the current "retina" simulated resolution instead of the full-screen video res. It seems that the bug is actually the "current size" display of quicktime player on Mac OS. On the other hand, you could request an enhancement to Retina program routines allowing the user to operate in either the current "Default" Retina mode or to default to 5K (or 4K resolution depending on the system) the way you think it is supposed to work at each user's discretion. Unfortunately, I believe Apple will claim there is no bug because the software is currently performing as it is programmed to work using four 5K resolution pixels to create a single 2.5K resolution pixel with HDR shading and not as you think it should on a 1:1 pixel resolution basis. Then you should file a "Bug" report regarding this issue. Limiting the video to “simulated” UI resolution is a bug. However, if it has this capability, then I would assume that it automatically resets the Retina screen from the "Default" 2.5K resolution to 5K resolution and then applies doubling to all non-image/non-video display elements/objects-i.e., the opposite of what Apple currently does. As to apps, not being a an Adobe Lightroom user, I cannot confirm nor refute your claim. I admit I'm not an expert but I have yet to come across a display card that can simultaneously set up multiple arbitrary areas of different resolutions which seems to be a prerequisite for what you want. I am sure there are apps that do it correctly, e.g. I thought the idea behind hi-dpi UI resolutions was to make UI text and icons big enough, but keep full res for media, like photos and videos. (I.e., if you check the "View" menu, you should find the "Fit to Screen" the only available viewing option while most third-party apps function in a similar manner whether or not other options are greyed out.) Thus, you must make the choice of seeing all screen objects in the 5K resolution mode with text and icons too small to really read/see or use the Retina/HiDPI (half-resolution) "Default" mode which scales the video to fit the available screen display area. Since Apple apps tend to be context adaptive, apps like QTX limit the player window to the "effective" resolution of your video display or, in your case, a 2560x1440 display area. Text in particular benefits from Retina-it looks smoother, with the curves on characters looking like curves instead of jagged steps.) ![]() ( I.e., the effect of a Retina display is to make everything look crisper. To compensate for this, Apple created what it calls the "HiDPI" mode, where each interface element is doubled in size vertically and horizontally (i.e., displays at 0.5X its resolution) and so appears at the same size as it would on a non-Retina display-thus halving the 5K screen to an effective 2.5K display as you also noted. User interface elements like menus and icons would look tiny (as you complained). If it did that and nothing else then there would be a problem. The choice is yours.īACKGROUND: Basically, Apple's "Default" resolution option converts a device's display to "Retina" by doubling the number of pixels vertically and horizontally, meaning it has 4 times as many pixels as a non-Retina counterpart. ![]() Either you view the media content at a screen resolution capable of supporting the native resolution of the video or you view the content using the "Default" setting. You can't have true 4K (or 5K) resolution using the "Default" mode setting. ![]() ![]() Can anyone suggest a player that can handle the full res 4K video from the default Mac OS High Sierra's "Default for Display" resolution?
