The switch, 4x DP cables, 2x HDMI cables, 2x USB-A cables, the desk controller, a power adapter and a guide.

That covers both computers to the switch. It does not cover the switch to your monitors. You need three more cables and they aren't included.

Price four decent DP cables and two HDMI cables separately and you're most of the way to this switch's cost, so the bundle is genuinely most of the value here.

Aluminium shell with plastic ends, 6.18 x 2.83 x 1.57 inches, external power brick.

Build quality is the one thing owners are unanimous about. Amazon's own tally is seven mentions of build quality, seven positive, zero negative.

No fan, which matters because the TESmart alternative has one and reviewers call it distracting.

The desk controller is the reason there's no hotkey, and it works. The only complaint we found was that it's overkill.

8K at 60Hz is 7680 x 4320 x 60 x 24 bits, which is 47.78 Gbit/s before blanking.

DisplayPort 1.4 carries 32.4 Gbit/s raw and 25.92 Gbit/s usable after 8b/10b encoding.

The claim needs 1.84 times the entire link. It's only possible with Display Stream Compression, and UGREEN never mentions DSC anywhere on the listing. TESmart and Level1Techs both state it plainly.

Same arithmetic kills the 4K@240Hz claim. Identical 47.78 figure.

One owner reports not reaching 4K@75Hz through it. Treat 8K60 as a best case with short cables and perfect conditions.

EDID is the block of data your monitor sends describing itself. A KVM with emulation keeps showing it to the idle computer, so that PC never notices the monitor left.

This one doesn't. Switch away and the DisplayPort link drops, Windows sees three monitors unplug, and your desktop collapses.

What you'll actually see: windows herded onto one screen, floating windows not coming back, monitor order occasionally swapping, a 3 to 5 second black flash on every switch.

Three screens makes it worse than one. Three links tear down instead of one.

UGREEN's own troubleshooting PDF tells you to expect the flicker.

Windows 11: Settings, System, Display, Multiple Displays. Tick "Remember windows locations based on monitor connection" and untick "Minimize windows when a monitor is disconnected". Free, and the highest-value fix.

Windows 10: PersistentWindows on GitHub. Free, snapshots your layout per display configuration.

macOS: System Settings, Desktop and Dock, Mission Control, untick "Automatically rearrange Spaces based on most recent use".

Hardware EDID dongles work but you need one per display, and Level1Techs sells theirs at 99 dollars. Three of those costs more than the switch.

One practical tip: put the monitor whose layout you care about on the HDMI port. HDMI tolerates a dropped link better than DisplayPort does.

Button or the wired remote. That's it. UGREEN states it in the listing.

Honestly it matters less than enthusiasts assume. The remote puts a button next to your keyboard, which is most of what a hotkey gives you.

Where it does hurt: if the button or the remote cable fails you have no second way to switch, and there's no serial control for automation.

TESmart gives you four methods, hotkey plus button plus IR remote plus mouse wheel. CKL and ATEN both do hotkeys too. If you switch forty times a day, that's forty reaches.

This is a bimodal product, not a mediocre one. 3.9 out of 5 from 371 US ratings, but 63 percent five star and 18 percent one star.

USB is the problem area. Amazon's own tally puts connectivity at two positive and five negative, the only attribute rated net negative. Several owners report USB ports dead out of the box, and one reports a replacement unit failing the same way inside a day.

No firmware update path, so nothing gets fixed in the field. TESmart, CKL and ATEN units are all upgradable.

When it works, owners love it. The risk is whether yours is one of the 18 percent.

CKL DisplayPort dual-monitor KVM, 94.99 dollars: same money, and you get EDID emulation and hotkeys. Two monitors instead of three. Winner if you can live with two screens, and it's the comparison that matters most.

CKL-923HUA-5, 329 new or 246.75 refurbished: cheapest triple-monitor switch with EDID we could find. HDMI only. Winner if the window shuffle would drive you mad.

TESmart DKS203-M24, 429.90 dollars: EDID, hotkeys, four switching methods, and it states the DSC dependency honestly. Has a fan. Winner on everything but price.

Level1Techs triple DP, from 750 dollars: still no EDID emulation, and rates itself at 8K@30. Honest, expensive.

99.99 dollars on Amazon, down from 109.99. In stock, sold by UGREEN, over a thousand bought last month. Used like-new from 95.99.

There is nothing else at this price that drives three monitors. The next cheapest triple-monitor option is a refurbished CKL at 246.75.

So the real question isn't whether this is the best triple-monitor KVM. It isn't. The question is whether 147 dollars is worth EDID emulation and hotkeys to you.

If you switch a few times a day and mostly run full-screen apps, probably not. If you switch constantly with a complex layout, definitely yes.

Do I need three cables I don't have?

Yes. The box covers both PCs to the switch, not the switch to your monitors. Budget three more cables.

What does my PC need?

Both computers need 2x DisplayPort and 1x HDMI outputs, live at the same time. A laptop with one USB-C output can't do this, and UGREEN warns against adapters and docks.

Why do my windows move when I switch?

No EDID emulation. See the fix above, the Windows 11 display settings take two minutes.

How long does switching take?

Three to five seconds, and you'll see a black flash while the monitors re-detect.

Will it really do 8K at 60Hz?

Only with Display Stream Compression, which UGREEN never confirms it supports. One owner couldn't reach 4K@75Hz. Don't buy it for 8K.

What should I actually expect?

Three 4K60 screens comfortably. Three 1440p at 144 to 165Hz comfortably. 4K120 on a port is plausible. Past that, no promises.

Does driving three monitors reduce each one?

Each video path is a separate physical link, so in principle no. UGREEN publishes no block diagram, so we can't confirm it.

Does G-Sync work through it?

UGREEN says yes, VRR, FreeSync and G-Sync. That's rare at this price.

Is there anything cheaper with three monitors?

No. This is the floor. Next cheapest is a refurbished CKL at 246.75.

Should I pay more for EDID emulation?

If you switch often and run a complex window layout, yes. CKL-923HUA-5 refurbished at 246.75 is the cheapest way to get it with three screens.

Can I get EDID at this price?

Only by dropping to two monitors. The CKL DisplayPort dual at 94.99 has EDID and hotkeys.

What's the risk?

18 percent of US buyers left one star, mostly over USB. Buy somewhere with an easy return.
