Yes, dual monitors can sometimes have extra lag when watching high quality videos or gaming. This is because your computer has to process the pixels of two screens instead of one. The amount of memory you have and the ability to run dual monitors are unrelated. Running a high resolution like p, p and p will not slow your computer down.
The only thing it will affect is memory usage. As others have said, there should be no perceivable degradation in performance so long as the hardware pushing the 4K signal is capable. Second monitors, especially if only used for menial stuff, is basically the same as having stuff open in the background on one monitor.
The only difference is that a bit of usage is offloaded to the GPU. So, the long answer to the question if a second monitor affects gaming performance is that yes. It can decrease the performance of your game, but it will depend on what you are doing on your second monitor, what resolution you are playing at and what graphics card you have.
Some dual screen combinations, especially with high refresh rates, prevent GPUs from clocking down to minimal power state when idling at desktop.
Gaming performance is unaffected at large. Multiple applications can run across all three displays without constant minimization or resizing. Update Graphics Driver: Update the driver to the latest version available. With EyeFinity, the span for specific issues grows making updates more important. Check Monitors: All monitors don't have to be the same brand, type, or size, but all do need to support the same resolution. DisplayPort: If one of the monitors does not have a DisplayPort and you are using a resolution over x, an active powered adapter will be required.
Setup Process Use EyeFinity to set up multiple displays by following the steps below. Connect the displays to the notebook or docking station with the respective cables. EyeFinity Mode is now enabled. You will be prompted to set up individual displays.
Follow the on-screen instructions to complete the setup. Known Issues When looking at several web pages and video, the monitor s may flicker. When using an active display adapter and the high graphics or frame rate occur, the screen will go black. The active display adapter is powered by the computer's USB power. To resolve this black screen issue, unplug the connector from the USB 3.
To resolve this, do not apply pressure. Frequently Asked Questions Q. Can you span Blu-Ray movies across multiple displays? Can you use your notebook's display in addition to the three external displays?
The total number of displays usable at a time is three. You can use your notebook display if you only have two external displays but it is not recommended.
If you have three external displays connected, your notebook display will need to be disabled while in EyeFinity mode. No, as long as you can connect it to the notebook, you will be able to use it. But the overall experience may be affected by the individual specifications of the display. The software and hardware setup process is designed for the advanced PC skills. The current version of the ATI software application interface offers a large number of possible hardware options, and it is difficult to predict and explain every possible step necessary to create an EyeFinity single large surface.
Due to the availability of many hardware options, you may need to be familiar with unique dongles and adapters, different monitors and resolutions, and how to interface all the components together with the bundled ATI software. Because of these challenges, EyeFinity technology is recommended for PC experts looking to take advantage and experiment with the latest and greatest features available.
