CKLau4Kx2K@60Hz 2 Port KVM HDMI Switch with Audio and Cable, Dual Port KVM Switch HDMI for 2 Computers Sharing Keyboard Mouse Monitor and USB 2.0 Peripheral Support Hotkey Switching, EDID

I had tried a couple of different KVMs without success as I'm using a Microsoft wireless keyboard and mouse (small USB dongle plugged into the KVM. This KVM was easy to install and the wireless keyboard and mouse worked without a problem. I did notice I had mark the top of the USB going into one of the computers as that computer let the USB to be installed upside down (making it non-functional). This is an issue with the computer and not the KVM. I did run into an issue in which the push button selector stopped working. Of course, it was 3 days after my authorized return date with Amazon. I reached out to the manufacturer (website listed in another review or Q&A) and the responded promptly with some troubleshooting options. When that didn't work, they mailed me a replacement part at no charge. I really appreciate the company stood behind the product and did it without any hassle or issues. I would definitely buy this brand again!

I'm using this to switch between my home computer and my work laptop using a single monitor, keyboard and mouse. It was easy to set up and works perfectly. The included cables are nicely bundled to minimize clutter, the hotkeys to switch between computers work fast and every time, and the buttons on the device work perfectly with a nice tactile feel (you can feel the click). The option to turn off the beep is nice as the beep is quite loud.

I have had this for a little over 3 months now. Does what I need it to do, and I've only needed to fiddle with it twice so far. I'll come back and update this review if it does break on me, but so far so good.The Good:- Simple to set up, labeled ports are straightforward- Everything works, swapping back and forth is snappy- The wired remote is handy, I've had no problems hiding away the box and only using the remote.The Less than Good:- The audio jack introduces static noise to your speakers. Not noticeable when you have media playing (unless you're volume is way up on your speakers) but extremely noticeable otherwise.- HDMI connection is the most fussy part. When I originally set it up, I needed to fiddle with the cables and restart the device a few times to get the HDMI working. Same thing about a month ago.- Tried the hotkeys once and they just didn't work.

Worked perfect for 2 months and 7 days - Then it stopped only displays low graphics now. Well I saw the comments but I took a chance and it FAILED!!! 30 plus years as IT master, many OS databases etc... but I broke my own rule, "buy cheap, get cheap"Too their credit it worked perfect for 2 month and 7 days, then while working, first the mouse stopped, then the keyboard input stopped soon the video stopped. After a power cycle, only display low output graphics, no longer high modern graphics output and the mouse still does not work. So I removed the KVM, and everything works great, now I just need to get a new KVM. Be Warned!!! you get what you pay for.

So I will start by saying that this item comes from Hong Kong. However, I ordered it on Friday and it arrived by Monday, From Hong Kong. I was happily surprised that it moved in the DHL system that quickly. I installed it and am using it for my Dell XPS (Gaming PC) and HP ProDesk (Everyday Use). I did have some obstacles in my way. My Dell has an advances graphics card and the HP is your standard factory graphics card. I was not able to get the HP to play well. After rebooting a few times and resetting the cables I got both of the PCs to play nice. The Audio was an issue for me as well. I really wanted to use one headset for both systems (Hence one of the reasons that you purchase a KVM). I hear a humming noise on my headphones through the KVM switch. I would list the drivers for my audio but that isn't necessary. It is a KVM switch and all options should work well. I will use 2 headsets for each PC to assure good HD audio. My trackball...I love my trackball and it is my preferred method for mousing. It is acting weird and the cursor is not responding as it should. I tried calibrating and adjusting but it is still not responding as it should. The wired remote...It doesn't work. I tried to install and reinstall after every reboot and i got no response from it. Hot Key button off or on the wired remote would not work. There may be some hidden instructions on how to activate it in poorly written 3 page instructional pamphlet. I just gave up and threw the remote in the box because the KVM is at a arms reach (Thank god for that). I can say this...the switch is small but well built. It has a metal casing and does not feel flimsy or cheap. The cabling is well made and is of a good gauge. At some point I may decypher the instructions and get things to work right but I doubt it whereas I am an IT professional and it doesn't look promising.Pro's:Lightning Fast ShippingNot flimsy for a small device.Cables feel solid.Con's:Instructions are sadHumming sound in headphonesWired Remote won't workTrack ball mouse is not working

I got this KVM when the pandemic started, so I can connect the work laptop to my monitor/keyboard/mouse, and it worked out great.Easy to setup, has some configs to tweak, some neat shortcuts.The only thing I don't like is the beep - it can be turned off for switching between the channels, but the 'on/off' beep is still there, and it is a quite loud one.Update: After 2+ years of use it started misbehaving and I couldn't find the remedy, so I contacted the seller and they were kind enough to send me a replacement, even though the warranty expired.The communication with the support was easy, straight to the point, they tried to help with the issue, but when all else failed, sent a replacement. In 2-3 days I was back to normal.Very much appreciated!

KB、マウスのみならず、マイク・スピーカーも共有出来るKVMスイッチは、AMAZON 等のEコマースでも、秋葉原の実店舗・オンライン店舗でも探しましたが、少なくともこの価格帯では他に見つかりませんでした。ただ、画面・KB・マウスとも、切り替え時の動作が時々不安定で、KVMスイッチ側のHDMIポートを抜いて差しなおすと復旧します。恐らく本体パネル上の「ホットキー」ボタンが関係していると思われますが、他の対策はよくわかりません。価格以上の価値は、間違いなくあると思います。

商品画像では通常のACアダプタが同梱物に入っていますが、実際はUSB電源アダプタ+ケーブルです。これを繋がなくてもPCとケーブルを接続する事で本体側のインジケータランプ自体は点灯する為、バスパワー動作するのと勘違いしてしまいました。マニュアルは全部英語なので、苦手な人はちょっと面倒かも。初期状態設定だと切り替え時のビープ音がかなりうるさいので消した方が良いです。※本体のHotkeyON/OFFスイッチランプの点灯を確認してから、「右のCtrl」キー2回押しの後「B」キー押して「Enter」キーを押す。またWin/Macの混在環境の場合で、キーボードはAppleキーボードを使う場合はホットキーによる設定変更ができないので、一旦Windows用キーボードを繋ぎ設定変更を行った後にAppleキーボードに差し替えるのが確実です。（この辺は国内メーカーのKVMスイッチでも似たような物ですが）

普通に動作しました。WindowsでもMacでも問題なく動作します。切り替えは3秒くらいです。ただし、オーディオ出力にはノイズが混ざっています。

２PC,2画面、１マウス、１キーボード、１スピーカーで使いたくて巡り合えました。PC側のHDMIのみ使わずに、マウス、キーボード、スピーカーを切り替えて使ってます。反応も普通に良く、今のPC環境で必須ですね。
