I am using two Dell Ultra Sharp HD Monitors UP2414Q with my Mac Pro (late 2013) single processor quad core running el cap 10.11.1 with AMD vFirePro D300. The have been working seamlessly with Yosemite since plug and play install in April. Last week the Pro. MacBook Pro (Retina, 13-inch, Late 2013) - Technical Specifications. Retina display: 13.3-inch (diagonal) LED-backlit display with IPS technology; 2560-by-1600 resolution at 227 pixels per inch with support for millions of colors. Your MacBook Pro with Retina display comes with 90 days of free telephone support and a one-year. Using a TV with a Mac can also give you a second monitor, making work or gaming more productive and enjoyable. And in many cases, you can even connect two external monitors or TVs at once.

Believing is seeing.

The first 32-inch Retina 6K display ever. Up to 1600 nits of brightness. An astonishing 1,000,000:1 contrast ratio and superwide viewing angle. Over a billion colors presented with exceptional accuracy. And dynamic range that transforms the professional workflow. Introducing Apple Pro Display XDR, the world’s best pro display.

XDR. Dynamic range to the extreme.

The contrast your eyes see between brightness and darkness is very challenging to reproduce in a display, leading to the development of High Dynamic Range (HDR). With breakthrough backlighting technology, Pro Display XDR takes brightness, contrast, and color to a new level. Far beyond HDR, it’s Extreme Dynamic Range (XDR).

A brighter idea.

Typical desktop displays have sustained brightness around 350 nits. Some pro displays exceed this, but most can only sustain it for short periods of time. Pro Display XDR produces an industry-leading 1000 nits of full-screen sustained brightness and 1600 nits at its peak.¹ It gives you the power to maintain extreme brightness without ever dimming. Along with efficient backlight control, this delivers outstanding contrast between the brightest brights and the blackest blacks. The result is an incredible 1,000,000:1 contrast ratio and stunningly real XDR imagery.

Show your truest colors.

Pro Display XDR always gives you the truest representation of your work. A P3 wide color gamut provides a color palette capable of creating the most vibrant imagery. With true 10-bit color, Pro Display XDR can produce more than a billion colors with extreme accuracy. State-of-the-art calibration and a sophisticated algorithm ensure that you get the highest-quality color possible.

LED in a whole new light.

True-to-life imagery requires having extremely bright areas of the screen right next to extremely dark areas. Without precise backlight control, this can cause an unintended glow called blooming. Pro Display XDR is able to dramatically reduce blooming using advanced LED technology, light shaping, and intelligent image processing.

Innovation in every layer.

Every aspect of the light imaging system in Pro Display XDR is crucial to the overall quality of what you see onscreen. Each element builds on top of the last to create a display with unbelievable brightness and contrast.

576 blue LEDs work together.

Typical LCDs are edge-lit by a strip of white LEDs. The 2D backlighting system in Pro Display XDR is unlike any other. It uses a superbright array of 576 blue LEDs that allows for unmatched light control compared with white LEDs. Twelve controllers rapidly modulate each LED so that areas of the screen can be incredibly bright while other areas are incredibly dark. All of this produces an extraordinary contrast that’s the foundation for XDR.

Light is mixed and shaped.

For even greater control of light, each LED is treated with a reflective layer, a highly customized lens, and a geometrically optimized reflector that are all unique to Pro Display XDR. Through a pioneering design, light is reflected, mixed, and shaped between two layers to minimize blooming and provide uniform lighting.

Color is transformed.

Converting blue light to white is a difficult process that requires extremely precise color conversion. It’s why most display makers use white LEDs. Pro Display XDR accomplishes this conversion with an expertly designed color transformation sheet made of hundreds of layers that control the light spectrum passing through them.

Brightness is taken to the edge.

Pro Display XDR extends exceptional image quality to the very edge. To ensure that LEDs along the sides of the display mix well with adjacent ones, a micro-lens array boosts light along the edges. This creates uniform color and brightness across the entire screen.

One chip makes it all possible.

With a massive amount of processing power, the timing controller (TCON) chip utilizes an algorithm specifically created to analyze and reproduce images. It controls LEDs at over 10 times the refresh rate of the LCD itself, reducing latency and blooming. It’s capable of multiple refresh rates for amazingly smooth playback. Managing both the LED array and LCD pixels, the TCON precisely directs light and color to bring your work to life with stunning accuracy.

Superwide viewing angle.

When multiple people review work together on a single screen, it’s critical that everyone sees the same thing. While most pro desktop displays claim a wide viewing angle, in reality, color and image quality become distorted when seen off-axis. With industry-leading polarizer technology, Pro Display XDR achieves a superwide viewing angle that maintains exceptional color and contrast.

Nano-texture glass.

Light scattered to further reduce glare.

Less glare.
And even less glare.

Every Pro Display XDR screen is engineered for extremely low reflectivity. And if you’re in an especially uncontrolled lighting environment, there’s an innovative matte option with nano-texture glass. Typical matte displays have a coating added to their surface that scatters light. However, these coatings lower contrast while producing unwanted haze and sparkle. The nano-texture on Pro Display XDR is actually etched into the glass at the nanometer level. The result is a screen with beautiful image quality that maintains contrast while scattering light to reduce glare to the barest minimum.

Goes with the workflow.

Professionals require a lot from their displays. But each person has different needs. Resolution, reference modes, reliable calibration. Pro Display XDR has everything you need in a modern workflow, bringing a new level of efficiency to every production. It wasn’t just made for the pro workflow. It redefines it.

5K

Retina 6K. Expand your view.

Higher resolution means more than just a better-quality image. With a Retina 6K display, Pro Display XDR gives you nearly 40 percent more screen real estate than a 5K display. While most displays max out at around 150 pixels per inch (ppi), our Retina display has 218 ppi, providing astoundingly sharp and detailed imagery. It’s a massive creative canvas that easily fits 4K content, your tools, and much more all in one screen.

Many creatives. One vision.

Pro video workflows involve a range of professionals with unique setups. What’s always been missing is the ability to see the same image across an entire production. Pro Display XDR allows pros at every point in the process to experience exactly the same groundbreaking picture quality.

On location.

From the start of a shoot, Pro Display XDR reveals the content you’re capturing with incredible accuracy.

Post-production.

Image reproduction remains consistent across every point of your workflow, ensuring that everyone is always on the same page.

Reference modes.

It’s easy to adjust Pro Display XDR to match the requirements of HDR, HD, SD video, digital cinema, and broader uses such as photography, web development, design, and print. Just select a mode, and the display reconfigures itself to match a specified color space, white point, gamma, and brightness. And coming soon, you’ll have the ability to create custom reference modes.

True Tone.

The lighting around you can affect the way you see onscreen colors. True Tone on Pro Display XDR uses a breakthrough dual ambient light sensor design — with a sensor on the front and another on the back — to better gauge your overall lighting environment. This facilitates more exact adjustments to the color and intensity of your display, so you can have accurate viewing in all lighting conditions.

Expertly calibrated.

Pro Display XDR is optimized to more than meet the standards of creative professionals. Every display goes through our state-of-the-art color calibration. Each of the display’s 576 LEDs is also individually calibrated and has its light profile stored. An algorithm then uses this information to determine the exact light intensity at which each LED should be modulated to produce the best possible image.

A beautiful picture is only part of the story.

Pro Display XDR is stunning every way you look at it. Its screen stretches edge to edge with just a 9 mm border, so your work takes center stage. The aluminum enclosure is just an inch thick and features an innovative lattice pattern that reduces weight and increases airflow.

More air than metal.

The lattice pattern machined into the aluminum has many advantages. It more than doubles the surface area exposed to air, facilitating additional airflow and acting as a heat sink. This allows for fast and quiet cooling, enabling Pro Display XDR to sustain an extreme level of brightness indefinitely. Inlet and exhaust vents work through this pattern to draw in cool air and eject hot air away from the system, limiting the potential for hot air to be reingested.

Elevate your work. And rotate it, too.

Every aspect of Pro Display XDR was designed with pros in mind. Pro Stand is no exception. Height, tilt, rotation — it’s completely adjustable. It’s stable without taking up much space. And its ability to rotate to landscape or portrait makes it perfect for any type of work.

Fine-tuned fine‑tuning.

Pro Stand makes every adjustment of your display feel seamless. Precision tilting and 120 mm of height adjustment help Pro Display XDR adapt to any viewing condition. The angle of the display stays true even as you adjust the height. With Pro Stand, you get a display that feels weightless, moves effortlessly where you want it, and stays exactly where you leave it.

Every side is its good side.

Pro Stand gives you the ability to move between landscape and portrait whenever you want. All you have to do is unlock the slider and turn the display. Whether you’re a developer, a photographer, or a composer, you can see more of your work without endless scrolling.

Detach. Move. Attach.

Having the freedom to move between being on set and working in the studio can make a big difference. The magnetic connector on Pro Stand makes it easy to attach and detach from its polar-opposite magnet on the back of Pro Display XDR. These magnets guide the connection while latches automatically engage and securely lock the stand to the display. Detaching it is as simple as unlocking the slider.

Available VESA Mount Adapter.

Many pros have unique mounting setups for their displays. The VESA Mount Adapter attaches to the display in a matter of seconds for quick and easy mounting.

Powerful partnerships.

If you're trying to connect a 4K display or Ultra HD TV with your Mac, make sure your computer meets the requirements for using these external displays.

If your software and firmware are up to date, or if you can't see the image on your screen, try the steps below for your specific issue.

If the display image is blank or unusable

Try these steps if you don't see an image on your display. These steps can also help if the image on your screen repeatedly turns on and off (flickers), if horizontal lines appear (snow), or if the image is distorted (torn or scrambled).

These steps likely won't help if the issue is only happening in one app. If you see similar issues in only one window or app, check with the app's developer for updates or more help.

4k Monitor For Mac Pro 2013

Check connections

Check the connections to your Mac and external displays:

• If you're using an Apple notebook, try connecting its power adapter.
• Make sure the external display's power cable is securely connected and that your display is turned on.
• If you're using a Mac Pro (Late 2013) make sure your displays are connected to the right ports.
• If you're using a display hub, switchbox, or 'KVM,' try connecting your display's video cable directly to your Mac instead.
• Disconnect the video cable where it plugs into your Mac, then plug it back in to reseat the connection.
• If you're using a video adapter, unplug the video adapter from your Mac, then plug it back in to reseat the connection.
• If you're using more than one video adapter to connect your display (the adapters are 'chained' together), try connecting the display using only one adapter if possible. Some video adapters can't be connected together. For example, a mini DisplayPort to DVI adapter can't be connected to a DVI to HDMI adapter.
• If your display has more than one video connection, see if using another connection on the display works. If possible, check to see if using a different display or a different adapter works.
• Try using a different cable that you know is in working order. Check with the display's manufacturer to make sure you're using the cable they recommend.
• Restart the Mac with the display connected.

Detect your display

If you're using an external display, sleep and wake your Mac to make it check for connected displays:

1. Press the power button on your computer to put it to sleep, or choose Apple menu > Sleep.
2. Wait a few moments, then press a key on your keyboard or click your mouse or trackpad to wake your Mac.

If you're using more than one display, and you can see the image on one of the displays, you can also use Displays preferences to check for connected displays.

Adjust video settings

If there's no image on your display, try adjusting your display's brightness or contrast. If there's still no image, or the image appears torn or scrambled, try selecting a different video resolution in System Preferences.

Adjust brightness

• If you're using an Apple Display, press the increase brightness key on your Apple keyboard. To adjust the brightness of a secondary display, press Control-F2.
• If you're using a display that's not made by Apple, check the documentation that came with your display to see if it includes built-in controls for adjusting its brightness or contrast.

Change your display resolution

1. From the Apple menu, choose System Preferences.
2. Click the Displays icon.
3. Click Default for display. If you see more than one resolution listed, choose a resolution and refresh rate. If the display turns off when you change resolutions, press the escape key to undo the change.
   

If you can't change the resolution of your display because you can't see an image, restart your Mac in safe mode to reset the display resolution to defaults.

If starting in safe mode doesn't resolve the issue, reset your Mac's NVRAM and SMC to reset the video ports on your Mac to their defaults.

Check for third-party display software

If your display works only when your Mac is started in safe mode, and you have display-related software installed, check with the software's developer for updates, or try temporarily uninstalling it.

If an image appears fuzzy or blurry

If images or text on your display appear pixelated or blurry, check these things.

Check your display resolution

Make sure your display resolution in System Preferences is set to its default. If you're using a resolution that's scaled, the image might be magnified to fit the display. This can cause the image to look blurry in some apps.

1. From the Apple menu, choose System Preferences.
2. Click the Displays icon.
3. Select Default for display.
   

If you use a monitor or an HDTV connected with an HDMI cable, you might see a difference in video quality if your display is set to television mode. Check your display for a 'monitor mode' setting to get the best video quality.

Retina displays

If an app you're using appears low resolution on your Retina display, check to see if an update to the app is available. Most apps have been updated to use the higher pixel densities of Retina displays.

Lower-resolution images on some web pages might also appear 'softer' when viewed on a Retina display. This is because Retina displays have a higher pixel density and not all websites use Retina-ready images.

For example, the images below look different when viewed on a Retina display, but the same on a non-Retina display. This happens because the Retina-ready image has a higher pixel density:

If you see contrast or color issues

If your entire display image seems too dark or too bright, you can adjust the brightness and contrast from the Displays pane of System Preferences, or by using your display's built-in controls.

Adjust brightness and contrast

To adjust the brightness of your Apple display, press the brightness key or F2 key on your keyboard. You can also use the brightness adjustment for each connected display in System Preferences > Displays.

Displays not made by Apple sometimes have brightness and color adjustments built into the display. Check the documentation for your display to see if it includes built-in controls.

When you connect a display, projector, or HDTV using an HDMI cable, you might see a difference in video quality if your display is set to television mode. Check your device for a 'monitor mode' setting to achieve the best video quality.

You can also calibrate each display from the Color tab of Displays preferences to get the best color and brightness from your display.

If you see bright or dark pixels

If individual pixels on your display seem too bright or too dark, see these articles for more help:

Connecting displays with Thunderbolt 3 (USB-C)

The Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter connects Mac models with Thunderbolt 3 (USB-C) ports to older devices that use Thunderbolt (10Gbps) or Thunderbolt 2 (20Gbps). For example, this is the adapter that you should use to connect your MacBook Pro to an Apple Thunderbolt Display or a third-party Thunderbolt 2 storage device.
