Mixing Refresh Rates: Can You Connect A 60Hz And 144Hz Monitor?

It is possible to connect a 60Hz monitor to a 144Hz monitor. A user on Tom's Hardware Forum confirmed that they use a 1440p, 144Hz monitor as their primary monitor, connected with DP, and a 1080p, 60Hz secondary monitor connected with HDMI, with no issues. Another user on the same forum stated that they have a GeForce GTX 1060 Windforce OC edition, which has two DVI-D Dual Link ports, one HDMI port, and one DisplayPort. They plan to use the DisplayPort on the 144Hz and the HDMI on the 60Hz monitor, which should work without any problems.

Dual-screen setup

A dual-screen setup with a 60Hz monitor and a 144Hz monitor is possible. However, there are some limitations to be aware of.

Firstly, ensure that both monitors are connected to your graphics card and not your motherboard. The 60Hz monitor should be connected using an HDMI cable, while the 144Hz monitor should use a DisplayPort cable. This setup will allow both monitors to operate at their respective refresh rates. If you attempt to run anything involving fullscreen graphics on the 60Hz monitor, it will cap the 144Hz monitor to 60Hz as well. This is due to the limitations of the graphics card, which can only handle a certain amount of data at once.

Additionally, it is important to configure the monitors independently rather than cloning the main monitor. This means that the settings for each monitor, such as resolution, colour depth, and refresh rate, can be customised separately.

By following these steps, you can successfully set up a dual-screen configuration with a 60Hz and a 144Hz monitor, ensuring that each monitor performs to its full potential without impacting the other.

Refresh rates

It is possible to connect a 60Hz monitor to a 144Hz laptop. The 144Hz monitor will be able to run at 60Hz, and you can adjust the refresh rate to any value under 144Hz. However, it is important to note that you may experience tearing when running at 100Hz on a 144Hz monitor without using V-sync.

Additionally, when using a dual-monitor setup with a 144Hz and a 60Hz monitor, there is no need to decrease the refresh rate of the 144Hz monitor to 120Hz to fix lag issues. You can use different cables for each monitor without any problems.

Furthermore, when connecting a 60Hz laptop to a 144Hz monitor, it is technically possible, but the laptop's graphics card may not be able to deliver the desired frame rates for certain games. You may need to lower the game settings or resolution to achieve higher frame rates.

V-sync

However, V-sync can introduce input lag, especially in fast-paced games like first-person shooters. This is because V-sync forces the GPU to wait for the display to refresh before rendering the next frame. On a 60Hz monitor, this can result in up to 16ms of latency between when a frame is rendered and when it is displayed.

When using a high refresh rate monitor, such as a 144Hz monitor, screen tearing is less noticeable due to the faster refresh rate. As a result, some gamers prefer to keep V-sync disabled to minimize input lag, especially in competitive multiplayer games.

Additionally, V-sync can cause stuttering if your FPS drops below the monitor's refresh rate. This is because the GPU may not be able to maintain a stable frame rate, leading to fluctuations in performance.

To summarize, V-sync is a useful feature to prevent screen tearing, but it can introduce input lag and stuttering in certain scenarios. The decision to use V-sync depends on your personal preference, the type of game being played, and the performance of your hardware.

G-sync

When using G-Sync with a 60Hz monitor, the technology ensures that each frame is displayed as soon as it is rendered, reducing the input lag typically associated with V-sync at 60Hz. This results in a more responsive gaming experience, even at lower frame rates.

However, when pairing a G-Sync monitor with a non-G-Sync monitor, such as a 144Hz monitor, issues can arise. In a dual-monitor setup, users have reported stuttering and performance problems, especially when running hardware-accelerated apps on the non-G-Sync monitor. This is due to driver issues with Nvidia cards, where the different refresh rates cause stuttering in any hardware-accelerated applications.

To resolve these issues, some users suggest plugging the secondary monitor into the motherboard, utilising integrated graphics if available. This approach may not work for everyone, and in some cases, users have had to resort to purchasing an additional 144Hz monitor to eliminate the stuttering problems.

It is important to note that G-Sync is not supported over HDMI, and certain laptop models may lack the necessary DisplayPort connector or USB-C port with DisplayPort Alternate Mode support. As such, it is essential to consider the specific hardware configurations and limitations when attempting to use G-Sync with a 60Hz or 144Hz monitor.

DisplayPort

When it comes to refresh rates, DisplayPort is capable of supporting up to 144Hz. However, there are a few things to keep in mind. First, the DisplayPort version and cable quality can impact the maximum refresh rate. For example, DisplayPort 1.1 has a bandwidth limitation that may prevent achieving 120Hz or 144Hz. Second, the device being connected must also support the desired refresh rate. For instance, some laptops may only support up to 60Hz over DisplayPort, even if the monitor and cable support higher rates. Finally, the graphics card and graphics driver can also play a role in achieving higher refresh rates.

If you are having trouble achieving 144Hz with a DisplayPort connection, there are a few troubleshooting steps you can try. These include:

• Checking the DisplayPort version and cable quality.
• Ensuring that the device being connected supports the desired refresh rate.
• Updating the graphics driver.
• Adjusting the refresh rate settings in the display settings or graphics control panel.
