One would easily agree that input lag constitutes a significant pitfall amongst KVM users, whether for gaming or other tasks that might require high-speed input.
Every pro-gamer can relate to the effects of input lag on their gaming experience and general PC efficiency.
Does a KVM switch cause input lag?
At most, a tiny 1-3 ms lag is expected unless one is using a high refresh rate on their monitors. For instance, running a 120hz or higher refresh rate could increase input lag.
When you have too many components plugged into your PC, the processor might have a hard time handling all the data, and this may slow down the PC’s response time and cause input lag. Using second-rate cables with low-standard KVM switches can also result in a noticeable difference in input lag.
However, input lag should not be mistaken for response time.
Input lag (also known as input latency) refers to the delay between the source of input (keyboard, mouse, or controller) and the display of the image or frame on the monitor.
Also, input lag is measured in milliseconds and can be negligible or minute in amount, but it can make a huge difference to a gamer – because the speed with which the frames refresh improves competitiveness.
If you’re a pro gamer or tech enthusiast looking to run multiple computers with many peripherals on your workstation while minimizing space, then a KVM switch might come in handy.
KVM switches are designed to improve productivity, minimize space and save money by allowing users to operate multiple computers with one set of keyboard, mouse, and any other peripheral input device.

Do KVM switches affect gaming?
How a KVM switch affects your gaming experience depends on the quality of the switch and the bandwidth of the connections between systems, and how they interact.
Technically, a cheap control will work as a regular switch, but when you switch between machines, the first machine may assume the keyboard, mouse, or controller has been unplugged, which might create some complications in your gaming experience.
Some cheap KVMs coupled with low bandwidth might mess up the resolutions. In general, the only possible latency can come from the specialized keyboard port that some KVMs have.
IP-based KVM solutions are not recommended for low-latency gaming applications like CS-GO and Valorant. Local KVM solutions or LAN-based IP implementations are always the way to go for a smooth gaming experience.
In summary, Emulated KMS switches take time to initialize, Semi-DDM ones switch the video instantly but might cause some lag in initializing the peripherals, and lastly, DDM KVM switches have no lag in switching machines.
Do Wireless Keyboards/Mice Work With KVM Switches?
A very few KVM switches on the market actually support wireless keyboard/mouse. KVM Switches with USB Hub and KVM Switches without USB Emulation can support controlling sources with a wireless keyboard and mouse.
Are KVM switches secure?
Many unsecured KVMs lack the comprehensive security features that financial services companies should require.
Is your KVM hiding these vulnerabilities? Not all KVMs are secure.
While it helps to eliminate the clutter by allowing the use of one set of input devices over multiple systems, unsecured KVMs can be at the risk of unwanted security vulnerabilities.
When looking to buy a KVM switch, one should consider buying a NIAP certified secure KVM that is designed to block any path for signals to travel from one system to another and create air-gap isolation.
A secured KVM switch is essential to preventing the security issues that could occur in KVMs.
Does G Sync work through KVM?
G-Sync will work through a KVM as long as the monitors support it; however, we recommend keeping the DisplayPort cable lengths short (under 10 feet) for best results.
Do KVM switches work with consoles?
KVM switches are installed mainly to switch between the connected network devices, but console servers can access the system consoles of network devices to monitor and control their functionalities.
Are KVM switches outdated?
No, KVM switches are not in any way obsolete.
However, software alternatives are currently available that can be used to run multiple computers with one peripheral setup in gaming rigs or workstations.
KVM Switches offer a trade-off with ease of use, and its wired connections help reduce latency within input devices. So, it comes down to what the user is comfortable with using within their systems.
Is it possible to connect two computers to one monitor?
Two computers can be connected to one monitor using different port interfaces.
Most monitors are built with multiple input ports at the back, enabling you to plug in both computers at the various available ports – usually HDMI and VGA.
Switching between computers can easily be done by toggling the monitor input via the control buttons or remote control to select the preferred computer to display.
A better alternative is the use of a KVM switch which offers simplicity and can be used to connect more devices.
Can two monitors connect to one CPU?
Two monitors can also be connected to one computer device using different cables and ports.
One monitor must be connected to the HDMI port, while the other is connected to the VGA port using the respective compatible cables. You can toggle the display on the computer to either extend the display across both monitors or duplicate displays on both monitors.
Are KVM switches worth it?
Using a single keyboard and mouse to control multiple systems will save you both time and money. And who doesn’t want that?
Why does KVM cost so much?
KVM Switches are often seen as expensive amongst users – why?
The KVM technology is a broad area that offers many options and technologies that come with a wide range in price. Functionality plays a huge role in KVMs pricing – the number of CPUs, monitors, peripherals & users supported, the operating systems, technology, and cabling supported will influence the price of a KVM switch.
Basically, before choosing the right KVM suited for your setup, one must determine how many devices are connected and how the devices will interact. There’s a wide variety of options available to accommodate your budget when getting a standard compatible KVM.
