I recently got a 4K 60Hz monitor for my 13" MacBook Pro Late 2013. It supports both HDMI and DisplayPort, but since the included cable is a full-sized DisplayPort cable, I'm currently using HDMI. Back when the rMBP Late 2013 came out,  wrote about how it could support 4K@60Hz, but only on Windows because of a driver issue. I was wondering if that issue has since been fixed, and if it is possible for me to run my monitor at 60Hz.  I also tried to run it at 1440p@60Hz, using both System Preferences and cscreen, but neither of them worked. If it is impossible for me to use 4K@60Hz but it is with 1440p@60Hz, could you please let me know how? I am willing to purchase a MiniDP to DP cable if necessary.  Thanks in advance!

How do I find out the number, type, resolution &amp; refresh rate of additional monitors I can attach to my MacBook or MacBook Pro?  This is an attempt at a canonical QA, as per the Meta QA -   to try prevent the myriad "same but different" questions we get on every possible combination of computers, cable &amp; monitors There are perfectly good resources out there that Ask Different should not have to duplicate the efforts of.

I wanted to use a mini display-port cable then use "target display mode" to make the iMac an external display, but I just read that early 2009 iMac's don't have target display mode as a feature.  Anybody knows of a solution?

MacBook Pro (15-inch, 2016) with 2 USB-C to HDMI adapters. The setup works great if I start up in that configuration.   If I connect the adapters while the machine is running or simply sleeping, one of the monitors will never get a signal and stay in low power mode. The OS sees the monitor, it shows in the display arrangement settings and I can move the mouse into it, but until I restart, I can't see anything on it.  Once I have restarted I can let the machine sleep or whatever, and the display still works unless I disconnect the adapter. As soon as I do that a restart is required to use it again.   Using MacOS Sierra (10.12.4)  Using this adapter:

I've got a PC video card that I'd like to get boot screen support for on my Mac Pro. In particular, it is a Gigabyte R9 270X. The card is supported on the Mac once it boots, but I would like to get boot screen back since my old 8800GT has been baked in the oven a few too many times by now :-)  I've seen numerous guides on the internet about flashing the BIOS on the video cards and also ones that speak about adding the EFI BIOS, but in the haphazard forum approach, it isn't clear how this all works. To some degree, I've recently come away with the notion that you don't get rid of the existing BIOS, but rather add an EFI partition to it that the Mac would recognize. If that assumption is correct, then it would lead me to believe that adding an EFI BIOS that works on a similar card (R9 280X or 7950 which are both close but not quite) should work since I'm assuming that the existing BIOS would be similar enough to hook in. Failing that, I'm not clear how you would get a card-specific EFI BIOS for boot screen support.  Anyone an expert on this? I'm just really having a hard time trying to sift through all this and hoping to get a more direct answer!

I have a new , resolution of 2560 x 1080, connected via DisplayPort to my 2012 MacBook Air 13" via a  that reportedly does have pin 20 wired correctly. I had previously tried connecting via HDMI, but as the manual for the display indicates, Macs are apparently unable to use the full native resolution when connected via HDMI.  A negative experience I'm having is that, when the MBA goes to sleep, the display appears to disconnect. This is noticeable only when waking it: the extra screen blanking of the display automatically reconnecting is almost imperceptible, and would otherwise be of negligible consequence, except for the result that all of my windows that were on that display are resized to fit on the MBA's built-in screen's resolution.  So, I find myself having to constantly re-maximize or rearrange windows whenever I walk away long enough for the screensaver to turn on and/or the computer goes to sleep. This is really aggravating, as I do arrange my windows quite particularly.  My options are seemingly thus:   Replace cable - maybe this is a manifestation of the pin 20 problem, but the display does awaken, just dis/re-connects annoyingly. Replace monitor - maybe something is wrong with this unit or this model?   I don't have another DisplayPort monitor easily accessible, but I might be able to borrow one or at least find one I can use in a store just to demonstrate that it's a DisplayPort or OS X problem and not a unit/model problem.  Tweak something in OS X - maybe there's a setting that I can alter that will disable this behavior, without having to disable screensaver or sleep. Suggestions welcome! Replace MBA - I'm already planning to pick up a new Macbook Pro this month, but I don't know if I'll get it in time to be within the display's return period, should I decide to return the display. I have a feeling this is not a reliable solution, because it's unlikely that the new machine wouldn't exhibit this behavior unless the behavior would change between Thunderbolt and Thunderbolt 2. ??? - this is where you ingenious answerers come in.

What's the best way of connecting two Dell P2415Q 4k displays to the MacBook Pro 2016 with TouchBar and TouchID?  I have the monitors connected to an older MacBook Pro currently with two mini-DisplayPort cables. Can I somehow reuse those cables or do I need new ones?  Apple's support page  lets me know that:  "Note that although it uses a Mini DisplayPort connector, the Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter doesn't support connections to Mini DisplayPort displays."  So I guess reusing the cables is not the way to go?

I have the Late 2013 Macbook Pro, which has two USB 3.0 ports and two Thunderbolt 2 ports. I currently use both USB 3.0 ports and one TB2 port. I want to connect a third USB 3.0 device to the machine, but I don't want to use a USB splitter on one USB port as I'm concerned the devices would draw too much power from the bus. I have no current use for the second TB2 port and I would love to be able to use it for this purpose.   Browsing extensively online, I've found numerous docks, such as , that connect via a Thunderbolt cable. This would work, but it's an expensive, 'bulkier' solution (and not the one I'm looking for).   I'm aware that a USB 3.0 device wouldn't be able to take advantage of Thunderbolt's I/O speeds, but it's certainly compatible, which is all I'd need. After all, Apple even sells a . I also know that Thunderbolt is not only used for digital video purposes (along with the TB > Firewire option, there exists ).   There are almost no Thunderbolt to USB 3.0 cables/adapters on the market. I'd think this hardware would be more prevalent given the prominence of USB devices out there. What adapters are available for OS X?

Currently the MacBook's display works as primary, so every application I open gets open on the 13" and I have to drag it to the 24". I also don't have access to the dock on my 24".  Is is possible to turn off the MacBook screen and use only the one attached via DVI?  (I've just connected my 24" HP LP2475w via Mini DisplayPort to DVI to my MacBook Pro 13", which works great except for this one thing.)

I want to buy a Mac Mini and I want to use it with my laptop monitor. My laptop is Lenovo Y510P. I searched some documents for using Mac Mini with laptop monitor and I only found a solution to using with an Apple laptop unfortunately.  My laptop doesn't have a video input but can I use the Mac Mini via an external video capture devices etc? Or is there a way to use Mac Mini with laptop monitor?

I want to connect my laptop (Inspiron 15 5000 Series) to a 4k display. When I read online about this it seems that HDMI 2.0 is a necessaity to handle the large resolutions / refresh rates involved to get full benefits of a 4k display.  Use case: I'm not going to use this to play games. Most of my use-case is editing documents, emails, spreadsheets and some engineering drawings and video (watching not editing).   The goal behind going 4k is to boost productivity by having more things open at once to read side by side.   I looked into the Dell specs and they only mention an HDMI without going into the details of what type or whether it will support HDMI 2.0 / 4K TV.     How do I tell whether my Dell Inspiron Laptop (i7 7500 U processor) supports this?  I looked under the Display Adapters and can see that I have an "Intel HD Graphics 620"  listed.   Will this suffice to tell me if this display adapter will support HDMI 2.0 / 4k display?   Or should I be checking out some other settings?  Thanks!

I have a laptop with a 4K (3860×2160) display, but there are a lot of problems. A lot of virtualization programs aren't compatible with 4K resolution.  VMware Workstation and VirtualBox don't support 4K display in the list of the display's resolution. How I can set the resolution of the display in a virtual machine to 4K?

I just bought a new HP Pavilion dv7t Quad Edition laptop that has HDMI out. I already have a couple of monitors that are VGA and I'd like to hook up one of these to dual monitors.  I've read some sketchy reviews of products that try to convert directly from HDMI (digital) to  VGA (analog), so I was wondering if someone has a good recommendation on how to hook these two together.

I'm thinking about buying the new MacBook Pro with 4 USB-C ports.  I want to attach two screens, mouse and keyboard and ethernet to the MacBook Pro while using the fewest number of USB-C ports possible.  So what I need is an adaptor with:   two DP or HDMI ports (or one DP port with daisy chaining support) two or more USB ports an ethernet port   Best case would be a hub to which all devices are connected with a single connection to the MacBook Pro, including power supply. Worst case if attaching the MacBook Pro to the devices would require me to use all four of USB-C ports.  Given the answers up to far, I can tell that:   Daisy chaining might or might not work with the MacBook Pro (since it requires DP1.2 which is supported by the graphics chipset, but it's uncertain if it's supported by the MacBook Pro itself) I can attach the monitors with two cables as a last resort, leaving me with two ports for the remaining peripherals.   What I still don't know:   Would daisy chaining work with a hub or does it require the first monitor to be directly attached to the MacBook Pro? Does some kind of hub exist supporting attachment of all listed devices with a single upstream connection to the MacBook Pro?

I own an early 2013 15'' MacBook Pro (MacBookPro10,1), and I've been running every macOS update till Mojave, included. The mac has two GPUs, which get selected automatically depending on the running apps:   Intel HD Graphics 4000 (integrated) NVIDIA GeForce GT 650M (discrete)   Recently I've been reading about the fact that macOS Mojave has dropped any support for Nvidia GPUs, and digging further I've found out that users have been reporting issues with my model specifically. Apparently, since High Sierra there have been issues with the GeForce GT 650M and macOS, with GUI slow downs and crashes. I've found plenty of posts of people complaining about the lack of support and drivers from Apple.  Personally I have not observed any of these issues, but now I wonder. I know for sure that I've been using the discrete GPU often (I track my energy usage), but maybe I've just not noticed the slowdowns.  I've inspected the version of the Nvidia drivers (system report > software > extensions), and it says:  GeForce:    Version:          12.0.24   Last Modified:    12/10/2018, 05:10   Bundle ID:        com.apple.GeForce   Notarised:        Yes   Loaded:           Yes   Get Info String:  GeForce 12.0.24 355.11.10.50.10.103   Obtained from:    Apple   Kind:             Intel   Architectures:    x86_64   64-Bit (Intel):   Yes   Location:         /System/Library/Extensions/GeForce.kext   Kext Version:     12.0.0   Load Address:     18446743521870100000   Loadable:         Yes   Dependencies:     Satisfied   Signed by:        Software Signing, Apple Code Signing Certification Authority, Apple Root CA   They seem to have been updated one year ago (with Mojave?), but that doesn't fit with what I've been reading about the total lack of support.  Does anyone know what's the current state of the game for my MacBook Pro model?

I have a 2017 MacBook Pro. It has 2 USB-C ports on the left side and I use an Aukey hub to provide more ports (4 USB, 1 HDMI, 1 USB-C) and always to connect two monitors.   I connect one monitor through the hub with the HDMI port and another directly to the MBP with a USB-C adapter. Sometimes when I connect the hub to the Mac and the 2nd monitor to the Mac, it works as it should with no problem...but more than half the time I have to connect, disconnect, jiggle, jangle, switch ports, reconnect HDMI, etc. and hopefully they will both work. OFTEN, I can only get one monitor to fire up.  Is there any kind of software fix or reset that might solve this issue? Any other thoughts welcome. Thanks.
