As amazing as the services is there are some bugs and annoyances you may occasionally come across.

How to Optimize Your Netflix Experience. 

Netflix is by far the biggest and best streaming service on the market, its original content list is staggering and has massive growth forecast for the coming years, with 700 new tv shows and movies planned. For any users accessing Netflix content from Windows-based PCs, particularly from browsers, like Firefox and Chrome, you may occasionally experience video and audio sync issues. In most cases these sync problems can be fixed with a browser or system restart, however, if they persist after doing both, you may need to make some changes to your system.

Note: If you are watching Netflix from a laptop running on battery and are having sync issues, the quickest and easiest fix is to connect your computer to mains power. Nine times out of ten this will fix this issue. If you can’t connect to power or don’t want to, continue with the steps below.

You should also make sure that the browser you are using is fully up to date, if you are running an older version of Chrome, Firefox, Edge, Opera, etc, Netflix may encounter problems.

How to Fix Netflix Audio and Video Sync Problems. Audio Faster Than Video. (Option 1: Adjust Playback Preferences)

The most common reason for audio and video sync issues is the overall power of your system. If your computer or laptop isn’t powerful enough it will sometimes struggle to play content correctly, especially HD and UHD content. So if your device is a little dated, you may need to adjust the quality settings Netflix is playing content in. To do this, sign into your account, select your user, go to Account, then click on Playback Settings.

Here you will see a list of options Automatic, Low, Average, High. By default, it should be set to Automatic, which will play content in the best possible format for your Internet connection. If your Internet connection is capable of playing content in HD or UHD Netflix will automatically do so. This is where problems arise, if your computer can’t handle HD or UHD, sync issues occur. So to prevent this try manually changing your quality options, start from the highest and work your way down until you find a perfect fit for your device. (if you have data limits, keep this in mind also)

On this page click Advanced Settings, change to the Advanced tab in the window that appears, then click Settings. Here stay on the Visual Effects tab and choose one of the four options. The first option, Let Windows Choose is the best option, however, if this is already set, you will need to try something else. Best Appearance will give you the best quality but use more resources, Best Performance will give you the best performance, but Windows will look pretty basic. The best option is to use Custom with all tick boxes disabled, then slowly enable boxes as you check video and audio sync on Netflix.

If none of the above options have fixed your Netflix audio and video sync issues, you can try reducing the refresh rate of your monitor to 60hz. At first, this may sound like a far-fetched fix, however, there are quite a lot of users who are reporting that this works on their machines, so it is certainly worth trying. How you do this on your system will vary so you will have to check the specifics for your setup, however, it will more than likely be done from your graphics control software.

On Dell laptops running integrated graphics right-click your desktop and select Graphics Properties. Next stay on the may General Settings page and make sure the refresh rate is set to 60hz. Once done, save the changes and check to see if the issue has been resolved.

If none of the solutions above have worked for you, you can try adjusting your Windows sound quality settings. Generally, this will be set to 24 bit, 48,000 Hz (Studio Quality) as standard but can be adjusted up or down considerably. For the best results try changing this setting to 16 bit, 192000 Hz (Studio Quality). This should fix Netflix sync on all platforms, Firefox, Chrome, and the Netflix app. Although I'm not using any high-end speakers, I haven't noticed any sound quality issues since making the change from 24 bit to 16 bit.

If you aren't sure how to change sound quality settings for playback devices on Windows 10, open the Control Panel select Sound, select your sound device, then click Properties. In the new window that appears, change to the Advanced tab and use the drop-down menu below Default Format to adjust the quality. Once you have made the change click Apply, then Ok.
