ATEN CS1944DP 4-Port 4K DisplayPort KVM

The Only 4-Port KVM That Does Not Lie About 4K

Most KVM switches that advertise 4K deliver 4K@30Hz - which is technically true and practically painful to use. The ATEN CS1944DP does 4K@60Hz across all four ports, and that single specification separates it from every cheaper alternative in the Indian market.

At ₹24,999–26,999, you are paying a premium. Part of that premium is ATEN's Taiwanese build quality. Part of it is import duty and retail margin - ATEN products are not manufactured in India and carry import costs that show up directly in the price. But the core reason for the price is that four-port 4K@60Hz DisplayPort KVM hardware is simply expensive to build correctly, and there is no cheaper path to this specification in India.

What Works

True 4K@60Hz via DisplayPort 1.2 is the headline and it delivers. For a video editor or 3D artist switching between a render workstation and a primary editing machine, or a finance workstation user running multiple trading terminals across different computers, 60Hz at 4K resolution is what makes the experience feel normal rather than sluggish.

USB 3.1 hub means peripheral sharing actually works for modern devices - USB 3.1 speeds matter when you are plugging in an SSD enclosure or a high-bandwidth device at the shared port. This is a meaningful upgrade over the USB 2.0 on cheaper KVMs.

Audio switching is included. When you switch machines, audio output follows. For WFH setups with a single speaker system and multiple computers, this eliminates managing audio output separately per machine.

Hotkey switching and the remote port selector both work reliably. The build quality - buttons, chassis, cable connectors - is noticeably better than TESmart or generic Chinese KVMs.

What Doesn't

Import duty is baked into the price. ATEN products arrive in India as imports, and the ₹24,999–26,999 range reflects that cost structure. You are not getting a fair comparison with a hypothetically India-manufactured product at this price - about ₹4,000–6,000 of what you are paying is the cost of getting it here.

Warranty is the genuinely uncomfortable part. ATEN does not have an official India service center. If the unit fails outside the seller return window, you are navigating a grey area: some MDComputers and Amazon India third-party sellers handle warranty exchanges directly, some do not. Verify the warranty terms with the specific seller before purchasing.

DisplayPort cables are not included. At this price, that is a legitimate complaint. Budget another ₹800–1,500 for four quality DP cables.

India Pricing and Where to Buy

Available at MDComputers and Amazon India through third-party sellers at ₹24,999–26,999. Pricing varies between sellers - MDComputers tends to be more consistent. Check both before ordering.

This is an imported product. The price includes the import cost, GST, and seller margin. There is no official ATEN India distributor storefront where you would get a better price.

Who Should Buy This

Video editors, 3D artists, architects, or finance workstation users running 4 machines who cannot compromise on display quality. WFH power users with a dual-PC setup plus a test machine or server who have a 4K DisplayPort monitor as their primary display. Anyone who has tried a cheaper 4K KVM, hit the 30Hz limitation, and wants to actually solve the problem.

Who Should Skip This

If you have 2 machines, buy the ATEN CS1922 instead - it is roughly half the price for 2-port 4K@60Hz DP switching. If your monitor is HDMI-only, the CS1944DP is not compatible - you need a DisplayPort monitor. If budget is the primary constraint and you can accept 4K@30Hz or 1080p@60Hz, the TESmart 4-port DP KVM at ₹14,999–15,999 does the job for less. And if warranty and official India service matter to you at this price point, ATEN's India support situation will frustrate you.
