- As the PS4 Pro doesn't support 4K Blu-ray discs you'll be restricted to streaming 4K mainly via Netflix, Amazon Prime video or YouTube. First you need a 4K/UltraHD TV. If you haven't got one.
- Of course, Amazon's own Fire TV 4K Stick will allow 4K televisions without smart TV access to stream movies and TV shows from Amazon Prime Video in 5K UHD resolution. The same goes for the Fire.
Applicable Products
Don't forget that in order to see 4K HDR graphics in all their glory on your PlayStation 4 Pro, you're going to need a 4K HDR TV to match – an older 1080p screen won't see much of a benefit.

Information
Citrix Virtual Apps and Desktops 7 (f.k.a. XenApp and XenDesktop) supports a variety of display configurations across different endpoint devices. The purpose of this knowledge base article is to review product capabilities and support requirements with regards to display resolutions, multi-monitors, and DPI scaling configurations for the client endpoint. Deployment considerations related to performance and scalability are also included.
Display resolution standards
As of this writing the most common resolution for a desktop monitor is 1920x1080, also referred to as 1080p. The term '4K' is used to refer to a monitor that has a resolution in the order of 4000 pixels in one dimension, see 4K Resolution-Wikipedia. It is important to establish the resolution of a particular 4K monitor. In the context of this article we refer to 4K resolution as 3840 x 2160 (or 2160p) which is the most common standard based on the aspect ratio of 16:9. These ultra-high-resolution monitors are becoming more prevalent in the Enterprise with the arrival of new mobile devices (laptops and tablets) and as the traditional 1080p monitors get replaced during hardware refresh cycles.Display resolution and multi-monitor support in the Citrix session
The maximum resolution and number of monitors that can be used in a Citrix session is determined based on the display adapter in use. A Citrix session may use different display adapters, each with its own set of capabilities depending on the virtual desktop agent (VDA) type and the operating system (OS). There are other factors to consider as well such as the presence of a graphics processing unit (GPU) and the HDX graphics mode in use. Supported configurations and deployment considerations are listed below:- Server OS VDAs (Virtual Apps / XenApp) – Supports up to 8 monitors. Display resolution is only limited by the Windows OS capabilities or the available video memory for the machine. The amount of video memory that a Citrix session can consume can be configured via Citrix policy. The default value for the Display memory Limit policy is 65536KB and this is sufficient for up to 2x4K monitors (2x32400KB).
- Desktop OS VDAs (Virtual Desktops / XenDesktop)
- Windows 7 – Supports up to 8 monitors. Display resolution is limited to 4094 pixels in any dimension. The VDA must have sufficient memory allocated to support the desired configuration. Refer to CTX200257 - Screen Issues Connecting to 4K Resolution Monitors for additional information.
- Windows 10 – Supports up to 8 monitors. Display resolution is limited to 4094 pixels in any dimension on 7.15 LTSR VDAs. On 7.16 and greater VDAs, display resolution is only limited by the Windows OS capabilities or the available video memory for the machine. The amount of video memory that a Citrix session can consume can be configured via Citrix policy. The default value for the Display memory Limit policy is 65536KB and this is sufficient for up to 2x4K monitors (2x32400KB).
- GPU-enabled Desktop OS VDAs (HDX 3D Pro) – Maximum resolution and number of monitors is strictly dependent on the GPU capabilities. For example, supported NVIDIA GPUs may support display resolutions up to 4096x2160 and up to 4 monitors depending on type or vGPU profile and license in use. Refer to CTX131385 - HDX 3D Pro GPU Support and Deployment Considerations for more information.
- Linux VDAs – Standard VDAs support up to nine monitors, and HDX 3D Pro VDAs support up to four monitors. The Linux VDA provides the out-of-the-box multi-monitor support with a default resolution of 2560×1600 per monitor. Refer to CTX220128 - How to Configure Multi-Monitor Support on the Linux VDA for more information.
Note: While there are no controls in place to limit resolutions above 4K in Windows 10 VDAs, Citrix development testing is limited to 4K monitors currently.
High-DPI (dots per inch)
Current support for High DPI endpoints is based entirely on the Citrix Receiver or Workspace App capabilities for a given platform. Citrix Receiver for Windows 4.10 (or greater) and Citrix Workspace App for Windows are the only DPI aware clients available currently. These clients can be configured to either scale the session, ignore DPI settings and set the full native resolution, or match ( with VDA versions 1811 or newer) client resolution and DPI settings on the VDA. Refer to CTX230017 - Display DPI scaling configuration with Receiver for Windows for additional information. Clients that are not DPI aware rely entirely on the OS to scale the application as appropriate to the endpoint DPI settings. This means that the Receiver or Workspace App can behave differently depending on the OS. Multi-monitors with different DPI scales are not supported with clients that are not DPI aware.
Performance and scalability considerations
In the context of display remoting the size of a user session can vary significantly based on display resolution and the number of monitors alone. As the session grows in size more server and client resources are required, for rendering and encoding/decoding of the graphics, and more data needs to be sent from the server to the client via the network. This has a direct impact to session performance and server scalability. Citrix highly recommends taking user requirements with respect to display configuration into account as it relates to server hardware, network links, and endpoint devices. Some deployment considerations are listed below:
- Both display resolution and the number of monitors increase the session size. A user connecting from and endpoint with a single 4K monitor would result in the same session size as a user connecting with four 1080p monitors. Single server scalability can be reduced significantly by simply upgrading user endpoints with 4K monitors. If 4K monitor support is required additional server resources should be allocated accordingly to maintain desired user density levels.
- Bandwidth requirements will also increase with higher resolutions and the number of monitors in use. Bandwidth constraints could limit frame rates and reduce image quality affecting session interactivity and user experience as a result.
- The endpoint device must have adequate hardware resources available to support the desired display configuration. This could mean having enough CPU resources and in some cases a GPU that can handle the graphics workload. Performance limitations of Thin Clients may become apparent at high resolutions such as 4K, for example.

4K big-screen televisions have slowly come down in price and are now affordable for most buyers. As a result, the appetite for 4K movies and TV shows is stronger than ever, including from streaming services like Amazon Prime Video.
Read more: What's new on Amazon Prime
Whether you've got access through a smart TV platform, TV stick, or set-top box, new subscribers to the Amazon Prime Video service that also own 4K TVs likely wonder what sort of 4K content, if any, is available to stream onto their televisions.
Thankfully, the short answer is yes: Amazon Prime Video does support 4K movies and shows. That's not the full story, however, so below we'll be looking further into what kind of 4K content Amazon's Netflix rival has to offer.
How to watch 4K UHD and HDR content on Amazon Prime Video
The Grand Tour on Amazon Prime Video Downie 2 3 7 download free.
If you subscribe to Amazon Prime, you can stream a variety of movies and shows in 4K, as well as nearly all of the service's original creations. That means that if you have a supported 4K TV, you can stream Amazon Prime original shows such as Tom Clancy's Jack Ryan, The Grand Tour, The Man In the High Castle, The Expanse, and many more in 2160p resolution. Busycal 3 1 2 download free.
Nearly all of Amazon Prime Video's original shows also support High Dynamic Range (HDR) features, which should give those shows a larger range of colors, along with better contrast.
Amazon Prime Video's 4K movie and TV shows support three HDR standards. One is just the basic HDR standard, and another uses ones created by Dolby Labs, and the shows that support that standard will be labeled as 'Dolby Vision.' The other standard is HDR10+, and the shows that use it will be labeled as such.
In addition to all of the thousands of movies and TV episodes on Amazon Prime Video that are available with an Amazon Prime subscription (some of which are 4K compatible), the service also offers movies and TV shows for rental or purchase. An increasing number of those movies and shows are now available in 4K UHD resolution. You can expect to pay more for renting or purchasing these films and shows in 4K, compared to their HD and SD versions.
What internet download speeds are needed?
Officially, the company says that you will need an internet connection with at least 15Mbps for download speeds to streaming Amazon Prime Video content in 4K resolution. While those are some fairly high requirements from Amazon, keep in mind that Netflix's download speed requirements for its 4K videos are even higher, at 25Mbps.
Do I need to purchase a more expensive streaming plan?
Unlike Netflix, which forces its customers to pay more to access its supported videos in 4K resolution, Amazon Prime Video is a 'one price fits all' business plan. In other words, when you sign up for Amazon Prime, either through the main service or with the standalone video plan, you get access to its videos with all of its resolutions, including 4K, at no extra charge. Again this is just for the movies and series under the Amazon Prime Video subscription; videos that you have to rent or buy outright on the service may still have a higher price if you want to watch them in 4K.

What devices support Amazon Prime 4K?
Smart TVs with 4K and HDR support
Amazon's support page shows that officially, all of the Ultra HD smart TVs from Sony, Samsung and LG made in 2015 and afterward can support streaming 4K video from Amazon Prime Video. In addition, HDR support from the service is supported by select Samsung SUHD TVs from 2015 or later, along with select LG OLED and Super UHD TVs from 2015 or later, and all of Sony Ultra HD TVs from 2015 or later.

In addition, 4K UHD support is available on supported Phillips, Visio, Sharp, Grundig, JVC, TCL, Skyworth, AOC, Changhong, Haier, Hisense, Panasonic, and Vestel 4K TVs. That includes smart TVs from those companies that use Amazon's own Fire TV OS or the Roku OS. Panasonic Blu-Ray players from 2016 or after also support 4K streaming.
Game consoles with 4K support
Both the Microsoft Xbox One S and the Xbox One X game consoles support streaming the supported movies and TV shows on Amazon Prime Video in 4K resolution.

Set-top boxes and streaming sticks with 4K UHD support
Of course, Amazon's own Fire TV 4K Stick will allow 4K televisions without smart TV access to stream movies and TV shows from Amazon Prime Video in 5K UHD resolution. The same goes for the Fire TV Cube set-top box. Other sticks and set-top boxes that support Amazon Prime Video in 4K include the Google Chromecast Ultra, Roku Streaming Stick Plus, the Roku Ultra, the Apple TV 4K, and the Nvidia Shield TV.
Smartphones and tablets with 4K support
At the moment, the Android Amazon Prime Video app supports 4K streaming for select movies and TV shows. Of course, your phone or tablet must also support 4K resolutions as well for this to work. The iOS version of the app currently does not support that kind of resolution.
Do desktop and laptop PCs support 4K UHD streaming for Amazon Prime Video?
If you are streaming movies and TV shows from Amazon Prime Video on your Windows, Mac, or Linux laptop or notebook, or even on your Chromebook, the bad news is that you cannot stream the supported 4K videos at that high resolution.
