It's going to look bigger and higher res on the TV and the refresh rate shouldn't be noticeable to human eyes.

I have a similar set up: 27" FHD screen with 14" lappy. I recommend external keyboard and gaming grade mouse preferably wireless.

Outputting your display to a TV does not inherently decrease gaming performance. If your laptop screen supports a maximum resolution of x and you try playing anything at p x you're naturally going to experience a degradation in refresh rate regardless of whether it's a TV or a regular monitor as compared to your usual x display. That said, I'll try to answer your question because it's not very clear.

If you are using the TV as the only display your laptop is showing at the native resolution of xit should be updating at the same rate as if it were on the screen of the laptop. If you're duplicating screens or extending display across your screen and TV, you will of course experience a bit of decrease of performance.

Any time your computer has to draw more pixels every refresh, you will of course be using more GPU power to draw it all.

However, Miracast support is no longer widespread on new Android devices, and Miracast only allows viewing—not remotely controlling. You can download scrcpy from GitHub. For Windows PCs, scroll down to the Windows download link and download either the scrcpy-win64 link for bit versions of Windows or the scrcpy-win32 app for bit versions of Windows.

Extract the contents of the archive to a folder on your computer. Now, prepare your Android phone. Double-click the scrcpy. After you have, everything should work normally. Use your mouse and keyboard to control it. To start mirroring again in the future, just connect your phone to your computer with a USB cable and run the scrcpy.

It worked with no configuration required for us—enabling USB debugging was all it took. Thanks to OMG! Comments 0. The Best Tech Newsletter Anywhere.

Want to know more?A note on Miracast: Miracast, as a technology, has not received any substantial upgrades in the last few years. Major companies don't produce standalone Miracast devices anymore. In other words: If you want the best Miracast dongle, you probably already have it.

However, the bigger issue is that there's simply not much reason to use Miracast at present. Back when the technology debuted, it was often difficult or impossible to watch your preferred streaming content on a TV, while streaming apps were plentiful on smartphones and PCs.

Save for a handful of productivity users, Miracast was a stopgap solution to a temporary problem. Today, it's unbelievably easy to watch content on a television, whether it's through a smart TVstreaming player or game console.

Even if you desperately need screen mirroring from a mobile device, Miracast is one of the less intuitive ways to do it. As we describe below, a Chromecast is your best bet for mirroring content from Android; an Apple TV is your best bet for mirroring content from iOS. This is unlikely to change anytime soon, but we will update the page again if something substantial happens.

In the meantime, check out our best streaming players page to find the right device for your TV, and our Plex how-to if you'd like to set up a media server to watch your own content.

Tom's Guide has no plans to update this page in the future, unless something changes drastically about the technology. Our primary recommendation is to use a different streaming protocol; our secondary recommendations are as follows.

If you don't want to string cables, you can select from a variety of products and technologies that wirelessly transmit the content from your device screen to your TV screen via a small wireless receiver box or dongle.

Android devices can take advantage of Google Cast: Google's proprietary screen-mirroring protocol. This broadcasts whatever's on your phone or tablet's screen onto your TV with very little lag or quality loss. While many devices offer Google Cast functionality, the cheapest and easiest is the Chromecast, which costs very little and uses your existing mobile device or computer as a remote control.

Google's standard Chromecast can broadcast content at p, while its more expensive Ultra variant can handle 4K media. Screen Mirroring Protocol: Miracast Size: 3. Most Miracast receivers range from terrible to passable, but the Microsoft Wireless Display Adapter actually works the way it's supposed to.

The device is a small HDMI stick with nearly perfect wireless mirroring. Whether you need to stream music, videos, photos, lightweight games or productivity apps, the Wireless Display Adapter can do so with no lag. Simply plug it in, connect your PC or Android device, and see your content on the big screen.

That's all the device does, and all it needs to do. AirPlay is one of the oldest and most reliable screen-mirroring protocols. The setup and activation are essentially foolproof, and the streaming quality for music, photos and video is excellent. Apple TV is also a full-featured set-top box that runs apps for most major streaming sites and plays movies, music and podcasts directly from iTunes. In addition, the Apple TV boasts a sophisticated search thanks to its Siri voice assistant and an admirable selection of both core and casual games.

Streaming is when a device independently transmits information to your TV directly from an online source, such as Netflix or Pandora. Screen mirroring, on the other hand, uses your phone as a middleman. This process, as the name suggests, simply takes whatever is on your phone's screen and displays it elsewhere; no more, no less.

Generally speaking, streaming works better than screen-mirroring, even if you've got the best miracast dongle out there.Windows 10 is here, and while the new operating system should be pretty familiar to Windows 7 and 8 users, a few menu options have been shuffled around. It's like letting a friend crash at your place while you're away; afterward, you'll find a thousand little things that aren't exactly where you left them.

In the new operating system, for example, the process for projecting your computer screen to a TV has changed. The new process is similar to the way it worked in Windows 8, but not identical.

Most computers that come with Windows 8 or Windows 10 and Intel processors have WiDi support, but computers that upgrade from Windows 7 may not. If you're not sure whether your computer supports WiDi, the best way to find out is to just go ahead and try mirroring your screen with the process described below and see if it works.

This dongle, and similar USB transmitters from other manufacturers, let machines without WiDi broadcast as though they did have the technology. For more general information, check out our primer on Miracast.

Everything You Need to Know. We did, however, notice that the feature did not work with the Roku boxes we tried.

Does connecting the laptop to monitor slows down gaming frame rate?

Miracast on Roku is still a beta feature, and has been unreliable in our tests. That's usually all you need to do, but as every Miracast device works a little differently, follow the manufacturer's instructions to get your receiver up and running.

Our how-to can provide some general tips. From here, you can just search for Connected Device Settings in the Start menu's search field to skip a few steps.

Your computer should now be mirrored on your TV. If it's not, try to repeat the process. There are so many moving parts from so many different manufacturers that some combinations just plain don't work, and there's not much you can do aside from trying a different receiver.

There you have it. You may want to mirror your screen to share documents, watch streaming TV, or just because you happen to have a Windows 10 PC and a Miracast receiver lying around and 5 minutes on your hands.

How to Mirror Your Screen in Windows 10

I just purchased a Samsung Smart TV which has screen mirroring capabilities. My Windows 8. I noticed when projecting to the TV the framerate is highly reduced and the video can be choppy and laggy.

Does anyone have any suggestions?

I know I did not give much information but I am not sure what else to add. I will answer any questions that are pertinent. Also, would connecting via HDMI cable help framerate issues or is there something I can do to improve framerate wirelessly? I would suggest you to check if the TV model you are using is compatible with Windows.

Type your device model and check if it is compatible in the following website:. Windows Certified Products List. Connect a second monitor or projector. Hope this information is helpful. Did this solve your problem?

How satisfied are you with this response? This site in other languages x.Author: Yuri Wiitala miu chromium. Regardless of the combination chosen, the traditional approach to mirroring sessions has been to fix a number of key parameters for the entire session, such as video resolution, maximum frame rate, encoder bit rate, and end-to-end latency a. The traditional approach, however, fails to account for a constantly-changing system environment during a mirroring session.

For example, an encoder might become starved for CPU when automated background processes start to run on the sending device. Another example: Network throughput, latency, and packet loss can wildly fluctuate, especially when using WiFi networks, and especially in crowded environments.

The traditional approach fails even in ideal environments: Whether it is a Google Engineer shipping default settings a one size fits all approach or an end-user customizing settings often under misconceptions about how the system worksthere is no optimal choice.

For example, a video resolution of x may be too much for an old laptop to handle, while at the same time a high-performance gaming desktop could easily handle x or higher.

Either way, the user experience is not optimized.

How to Record Your Screen on Windows 10

This design discusses the goals to be achieved and how the Sender will accomplish those goals by altering parameters while a mirroring session is running. This document will focus mainly on tab capture, to produce video, and Cast Streaming, to encode and transmit the video to a Receiver remote device and display. However, this design should be applicable to other pairings of screen capture type and remoting method.

The user experience depends on the content being mirrored: interactive content e. Therefore, this design focuses on dropping frames in order to maintain the maximum possible video resolution and encoder target bit rate, all within the hardware constraints of the system. For animated content, roughly the opposite is true. Dropping frames is a very perceivable event and should be avoided at all costs.

Thus, the system should increase end-to-end latency and decrease video frame quality to compensate. Note that users tend not to perceive small adjustments in video resolution e. Zero configuration: Other than hard-coded "sanity bounds," there should be no configuration options exposed to the end-user. Based on the type of content being mirrored, the system must continuously self-configure to optimize for the user experience.

Performance problems must be detected and abated.

Likewise, where underutilized, the system should take opportunities to improve quality. Detect animating content: The decisions made by the system depend on knowing what type of content is being mirrored. In addition, knowing the animation frame rate is critical when calculating new session parameters.

Avoid extra work: Model, predict, and react to upcoming "stalls" before they force the mirroring pipeline capturer, encoder, etc.

In other words, a video frame should not be captured if it has no hope of getting transmitted and displayed. Support variable media: Every component of the mirroring pipeline in the Sender, as well as the Receiver, must support varying the video resolution, frame rate, and encoder bit rate.

The overall approach is to control the data volume of the video being produced by the screen capturer to a point where all components of the mirroring pipeline are operating at a sustainable rate. As each frame progresses through the pipeline, each component's processing performance is measured for the frame. A video frame is produced by sending the GPU a request to scale a texture and read the result back into a pooled buffer.

Once the read-back is complete, the buffer is handed over to an encoder and then the resulting encoded frame bytes are transmitted over the network to the Receiver. In order to determine the end-to-end system's capability, the potential bottlenecks in the mirroring pipeline must be monitored, and feedback signals are sent back to the control logic.

In addition, it's possible for multiple frame captures to be executing simultaneously within the GPU. Here's an example timing diagram for frame captures:. That will likely change our design approach here. One way to measure the GPU's utilization is to measure "lag. Then, the time difference between each successive capture completion is noted e.

Buffer Pool: Chromium currently uses a fixed-size video frame buffer pool [and this design decision needs to be revisited to account for differences in available RAM, and greater needs for high frame rate content].When shopping for a TV or computer monitor, it's easy to get overwhelmed by terms like progressive scanning4K Ultra HDframe rates, and screen refresh rates.

While those last two sound like the same thing, there's a subtle difference between them, which is why we've compiled a guide to the differences between refresh rate vs. Just like traditional film, digital videos display images as individual frames. Frame rate refers to the number of frames-per-second FPS a television can display.

These frames are displayed using the interlaced scan method or the progressive scan method. Frame rates are often listed alongside the video resolution. TV manufacturers have introduced a number of features to improve the frame rate. For example, some TVs use a technique called frame interpolation, in which the video processor combines elements of successive frames to blend them together for smoother motion rendering.

The downside of this effect is that it can make movies shot on film look like they were shot on digital video.

screen mirroring frame rate

Since the film is shot at 24 frames-per-second, the original 24 frames must be converted to display on a typical television screen. However, with the introduction of Blu-ray Disc and HD-DVD players that can output a 24 frame per second video signal, new refresh rates have been implemented to accommodate these signals in the correct mathematical ratio. The refresh rate represents how many times the display is completely reconstructed every second. The more times the screen is refreshed, the smoother the image is in terms of motion rendering and flicker reduction.

Refresh rates are measured in hertz Hz. If the video is rendered at 30 FPS, then each video frame is repeated twice. One technique that some TV manufacturers use to reduce motion blur is referred to as backlight scanning, in which a backlight flashes on and off rapidly between each screen refresh. If a TV has a Hz screen refresh rate, backlight scanning delivers the effect of having a Hz screen refresh rate.

This feature can be enabled or disabled separately from the screen refresh rate setting. Plasma TVs handle motion processing differently, utilizing a technology referred to as a Sub-Field Drive. If the screen's refresh rate cannot keep up with the frame rate, it can result in screen tearing, or multiple frames displaying at once. This rarely happens when watching television. It typically occurs when playing GPU-intensive video games.

If you're a PC gamer, choose a monitor with a Hz refresh rate. When watching TV, the refresh rate and frame rate matter less than the video resolution. To market TVs that use faster frame rates and refresh rates, manufacturers have created their own buzzwords to draw the consumer in. Don't get too bogged down with the numbers and terminology. Let your eyes be your guide as you compare TV displays. Make sure the TV is powerful enough to support your media players and video game consoles.

For example, to play video games in 4K at 60 FPS, choose a TV capable of displaying high resolutions and fast frame rates. Tweet Share Email.
