ATEN CS1922 Mini DisplayPort KVM Switch

The Only Mini DisplayPort KVM Worth Considering - If Your Setup Even Has mDP

At ₹13,999–14,499, the ATEN CS1922 is a niche product solving a niche problem. If you have two Mini DisplayPort workstations - think a MacBook Pro docked to a desk, a Surface Pro, or an older ThinkPad - and you need to share one monitor and keyboard between them without re-plugging cables every time, this is one of the very few KVMs built specifically for that. It supports Multi-Stream Transport, which means a single DisplayPort connection can drive two monitors simultaneously. In India, you are paying import duty on top of ATEN's already-premium pricing, so this is not a casual purchase.

What Works

The MST feature is the reason this KVM exists. If you are running two monitors off a single Mini DP output using a daisy-chain or hub setup, the CS1922 respects that topology when you switch. Most cheap KVMs break MST configurations on switch - you end up with one monitor going dark and having to unplug and replug. ATEN handles this properly.

Build quality is where ATEN earns its premium. The shell is solid metal, the port connections are tight, and hotkey switching (Scroll Lock twice) is reliable and fast - under a second for input switching. The wired remote port selector is a practical addition if your KVM lives behind a monitor or under a desk, which it often does in Indian WFH setups where desk space is limited.

USB 3.0 hub support means your peripherals - mouse, keyboard, USB drives - switch alongside the video signal. That matters when you are alternating between a work machine and a personal machine on the same desk.

What Doesn't

4K at 30Hz is the ceiling on the video side. In 2026, a ₹14,000+ KVM delivering only 30Hz at 4K is a real limitation for anyone doing video editing or motion graphics where a smooth, high-refresh display matters. If your monitors are 4K and you want 60Hz, the CS1922 cannot deliver that.

The bigger India-specific issue: ATEN has no official distributor network in India. What you are buying from Amazon India third-party sellers is a grey-market import. The price at ₹13,999–14,499 already includes 10–15% import duty absorbed into the seller margin. If the unit fails after 30 days, warranty claims go through the seller, not ATEN India - because there is no ATEN India service centre. This is a real risk at this price point.

Audio passthrough is absent. Not unusual for a KVM at this tier, but worth noting.

India Pricing and Where to Buy

Current range is ₹13,999–14,499. Available via Amazon India (third-party sellers - check seller ratings carefully before buying) and occasionally MDComputers. Flipkart stock is inconsistent. The import duty situation means prices can shift by a few hundred rupees depending on the seller's last import batch. Do not expect price stability.

No official ATEN India storefront exists. MDComputers is generally the more reliable vendor if they have stock, since they tend to carry enterprise networking and KVM gear for their corporate clientele.

Who Should Buy This

You have two Mini DisplayPort machines sharing a single desk. At least one of them uses MST for a dual-monitor setup. You have already confirmed your monitors and cables support daisy-chaining via mDP. You understand the warranty situation and have accepted it. For the Indian WFH dual-PC setup where both machines happen to use mDP docks - a Surface Pro paired with a MacBook Pro workstation, for instance - this is the only KVM that won't break your multi-monitor configuration.

Who Should Skip This

Anyone with HDMI or full-size DisplayPort machines. Do not buy a Mini DP KVM adapter chain when a proper HDMI or DP KVM exists at similar or lower prices. Anyone who needs 4K at 60Hz. Anyone who would be relying on the ATEN warranty for peace of mind - the grey-market import situation in India makes that warranty largely nominal. Anyone who is not 100% certain their cables and monitors support mDP MST; the setup can get finicky.
