Displays under System Preferences is it from the OS X built-in UI side. There are third-party utilities like Display Menu that offers additional resolutions. There is also cscreen if you want to do it in Terminal or incorporate it in a script.

You can see the current resolution in the Display system preferences. On a Macbook .. Retina, If you have scaled selected for resolution Hover your mouse over the current scaled selection and the resolution will be shown. If you have default selected for resolution then the resolution is not shown. ( I cannot check my non retina desktop at the moment) ...

I am an iOS developer, so have a bit of an idea what is causing this. Apple measure screen size in points rather than pixels, and depending on whether your screen is a retina display or not, will change the scaling factor between points and physical pixels. In your case, because you have a high-resolution Retina display, OS X is applying a scale factor of ...

This may be good or bad news deepening on how you look at it, but it’s the Dell 4K display, not your Mac. Both Dell model numbers 2715Q and 2815Q are notorious for this kind of flickering when used with MacBooks. If you search around on Amazon and other sites you will find similar complaints. We purchased 4 of the Dell 4K P2715Q monitors where I work, and ...

You may either download the OVA file for use with VirtualBox/VMWare: bio-linux-ova and import it ( File -> Import Appliance...) as a new VM. The ova file itself won't be modified. Before starting increase the video memory in the VM settings to 32 GB - 128 GB. The username/password are manager/manager. Or you download the latest Oracle VM VirtualBox ...

There's a subtle difference in the 2 technologies-- and kind of a misnomer. Apple's remote screen sharing technology is based on VNC -- Virtual Network Computing. You'd think this would be a virtualized technology that would provide you with whatever screen resolution you wanted, right? And Windows RDP -- Remote Desktop Protocol -- it would only give you ...

Very weird and unusual problem, I solved it this way. Open a terminal. Fin your DisplayPrefsKey ioreg -l -x -w0 | grep IODisplayPrefsKey Came out this: "IODisplayPrefsKey" ="IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/IGPU@2/AppleIntelFramebuffer@1/display0/AppleDisplay-756e6b6e-717" The important part is the last, ...

No, what you're asking for doesn't even make sense. If you want the display to be mirrored, then what's on the external display has to be exactly the same as what's on the internal display. What you need is a new external display with a larger physical screen size.

I had exactly the same problem, with the same monitor, Dell U2713 / U2713H / U2713HM / U2713HMt. I had two of them plugged in to my late-2014 Retina Macbook Pro 15" and only one was experiencing the problem. I tried 100s of different solutions (I can say for sure it's definitely not the cable!) and nothing worked. Just like you, I could get landscape ...

According to Apple's MacBook Pro (Retina, 13-inch, Late 2013) - Technical Specifications... So it looks like 1080p is the 60Hz limit.

It depends on which 4K you're referring to; if you're talking about the "actual" 4K (4096 × 2160), then: no (though you can come close). However, if you're talking about the UHD 4K definition (See the link to Wikipedia above), which is 3840 × 2160, you can do it using 3. party utilities such as QuickRes (paid), SwitchResX (paid), or Retina Display Mode ...

The most likely explanation is that your miniDP to VGA adapter is not an original/high-quality one. I've seen it happen before, and as soon as that person bought an original Apple miniDP to VGA adapter the issue is gone and native resolution is recognized without any issue.

Display menu doesnt do 16:9 on a Retina MBP...only 16:10 and 4:3

Not sure if this will help some people, but I figured this out for myself I have a 27" LG WQHD (2560x1440) display connected via HDMI to my 2014 13" Macbook Pro Retina. Enable Mirror Displays On the external monitor, select Optimize for: Built-in Retina Display The final result isn't perfect, but it makes my 27" external display look like a ...

I had the same problem yesterday. I needed to do recording on Windows (a Parallels VM) in 1280x720 (16:9), and Parallels always resets my Windows resolutions to whatever Macbook sees even when I use the config options Parallels say should not mess with that. I wrote this exact command with cscreen: cscreen -x 1280 -y 720 -r 60 Which allowed my Macbook to ...

You can go on settings -> Display -> ALT + Left Click on Scaled -> you will have a larger choice of resolutions. Else, you have some great softs for that, like switchResX : Why hassling with Apple's inbuilt screen settings, when there is so much more to get and much easier, too? With SwitchResX you get back control on your screen – or screens ...

I bought one (the Dell P2415Q) so can offer the results... Scaled options are: 1504x846, 1920x1080, 2304x1296, 2560x1440 and 3008x1692 That is to say, the macbook always outputs 3840x2160, 60Hz as far as the monitor is concerned. It just "looks like" those resolutions in terms of real-estate. 1920x1080 is the default, and other scaled resolutions are ...

Say you have you're screen set to standard (using 15" as an example here), then "it looks like" 1440x900 but it is really 2880 x 1800. Making this example easy, say the app runs in fullscreen, then it would usually load with 2880x1800. If you check the "Open in Low Resolution" it will load in 1440x900, thus being less sharp but in some cases better ...

From personal experience, the resolution has little impact of the 5 aspects listed. However, for me, there's a 6th and this seems to be affected quite a lot. Namely myself. I find that tiny fonts will make my eyes squint and I need to use more brainpower to read StackExchange questions, leaving a little less available to understand some of the remarkable ...

Dell supplied their monitor (at least my U2312HM) with DVI Single Link cable. That's the reason why you have incorrect resolution and frame rate. To get higher resolution you need to buy DVI Dual Link cable (with 9 additional pins) to get support higher resolution and frame rate. I sure that Dell made a mistake to supply the monitor with DVI Single Link ...

If you are looking for something to put into a shell script, you can run something like if [[ $(system_profiler SPDisplaysDataType | grep Resolution | head -1 | tr -d ' ') == 'Resolution:2560x1440' ]]; then # do whatever is needed to do for 2560x1440 end if You could also use a case statement to handle several ...

As an alternative, assuming you know the risks and have a backup, there are some utilities on Cydia which can change fonts that various iOS apps use. However, you have to jailbreak your device to use them. Just bringing this up as an alternative.

Just tried out the solution to reconnect to my TV and go to system Preferences -> Displays and select Built-in Retina Display of the drop-down menu Optimize for : Then take the HDMI cable out. It works!!

LOL you don't have to do all that nonsense. Just hold down the "option" key when you press the radio button for "Scaled" -- then all the options will appear. This is totally non-intuitive but it tells you this if you bother to read the Help screen that comes up when you press the (?) icon in the corner of the Displays preference pane.

OK it seems to have been caused by a plugin called Theme Font & Size Changer. After I removed this plugin, Thunderbird renders properly.

Press and hold the Option-Command-P-R keys immediately after powering on. This will reset the login screen resolution

You shouldn't be setting the resolution of Windows in Parallels. Boot Windows and choose Virtual Machine → Install Parallels Tools and follow the instructions. This sets the resolution automatically according to the window dimensions. If Parallels Tools doesn't set the right resolution in full screen, in Configuration set Full Screen: Scale to fit screen ...
