hello mats,
i bought this part about a month ago and i am very satisfied with it.
You can find the contents of the package on the manufacturer's website here: http://www.delock.de/produkte/S_11367/merkmale.html
The KVM switch only has one HDMI output, which means that you can connect it directly to one monitor. To use two monitors, you need an HDMI splitter or an adapter that splits the HDMI signal stream between two monitors. However, such an adapter or splitter is not included with the KVM switch and must be purchased separately.
(Question 1?... Yes, it works) - (Question 2?... Yes, it has two USB 2.0 and two USB 3.0 inputs) - (Question 3?.... 3840x1600 @ 144Hz? (Or only 120Hz as with 4K SDR? I don't know. but it should work as the resolution is automatically recognised.
How did you connect the USB devices to the KVM? Could be a power issue, so potentially using a USB hub with an external power supply could help? Other than that sounds like a hardware defect honestly :/
Unfortunately, no. The description is clear: "An HDMI output is also available, allowing two monitors to be connected, only one of which can be active."
I hardly think this would work. I could not use the switch. This switch cannot cope with a resolution of 2560x1440. So a splitter is probably also out of place.
Hello,
No, this KVM switch has no ethernet connectivity. There is USB 2.0 connectivity (from the PCs to the KVM hub) with a built-in USB sound card (1 jack out and 1 jack in), a DP + HDMI output and DP only inputs (no HDMI).
Mdietsche has actually already summarised it
DP output (switch) to DP input (monitor)
However, the resolution (because DP 1.1a) is limited to 2560 x 1440 @ 60 Hz.
USB see above
Yes, it also works with a wireless mouse. With the switch box, my USB mouse and USB keyboard, for example, are switched with the monitor. So 2 PCs and 1 piece of equipment.
Yes, that is quite possible. Enclosed is the data sheet: https://static.digitecgalaxus.ch/Files/1/0/0/9/5/5/5/9/datenblatt_11367.pdf
For more information on the exact specifications, it is best to contact the manufacturer directly.
The device has two USB-C ports, but these are not used for video transmission, but are USB 5 Gbps ports for peripheral devices. The two HDMI inputs must be used for video signals.
A USB Type-C port is provided for the 5 V power supply, but no charging function is specified for a laptop connected via USB-C as with a docking station. The device therefore does not support laptop charging via USB-C.
To summarise: Video signals come via HDMI, USB-C is only used for USB data and power supply, not for video or laptop charging.
1. if the keyboard and mouse are connected at the front, does it do passtrought? This is important to me because of the special keys. - 2. is there input lag with keyboard and mouse? - 3. at Delock it says: Resolution up to: DisplayPort output: 7680 x 4320 @ 30 Hz / 3840 x 2160 @ 120 Hz (SDR) / 3840 x 2160 @ 60 Hz (HDR) (depending on the system and the connected hardware) - Can the switch also work at 3840x1600 @ 144Hz? (Or only 120Hz as with 4K SDR?) (Or is it not even possible with this resolution?) MFG
After much trial and error, I managed to get the USB peripherals working one evening.
The next day, I boot up my PC -> HDMI still works, but the USB peripherals (keyboard, mouse, webcam, headphones) no longer do.
It's a shame, given that it's a device made exactly for these peripherals.
The PC is up to date, the KVM power cable is plugged in properly and the peripherals work directly on the PC.
What's more, when connected to the KVM, my peripherals are switched on and therefore powered.
In short, I've opened a ticket with supplier support and am waiting to hear back from them.
Any ideas?
I'm sorry, but I don't understand your question.
A hub between the KVM and the MacBook? What kind of hub? A USB-3 hub with a USB-C connection to the notebook?
But what would that be good for - apart from increasing the susceptibility to interference?
Or is your real question whether/how the Delock KVM can be operated with USB-C on the MacBook?
For that I would rather recommend something like this: Satechi USB A - USB C (0.15 m)
However, you have to clarify with Delock whether the Mac has the necessary drivers and whether the KVM can work at all.
The DisplayPort version itself specifies the maximum available bandwidth into which the combination of image resolution, refresh rate, compression and colour space, combined together, must fit. The refresh rate is therefore only one factor of many.
According to https://www.cablematters.com/Blog/DisplayPort/does-displayport-support-144hz, DP v1.4 (which is what this switch offers) can certainly do 1440p at 144Hz, but not quite 4K. 4K is only possibly possible if you restrict the compression (display stream compression (DSC)) and/or the colour space more (chroma subsampling (typically 4:2:2)).
Remember that all cables must also be designed for the desired DisplayPort version so that each component supports the desired bandwidth.
Switching the USB devices (mouse, keyboard, webcam, headphones) works. However, I can't get the picture from the notebook onto the monitor. My notebook only has an HDMI port, the switch only has DP inputs and I have found that an HDMI to DP adapter is not that common... and the adapter I bought is DP to HDMI. Problem No.1 should be solved with the right adapter. Of course, I could also connect the notebook directly to the monitor via HDMI, without detouring via the KVM switch. But my goal was to be able to press a button and switch from PC to PC without having to reconnect cables or change the source on the monitor. Am I making a mistake?
Problem No. 2 concerns the sound. I use a Bose Companion 50, which connects with a 3.5mm jack. However, I don't understand how to connect it to the switch so that either the sound from the PC or notebook is output via Bose.
Thanks a lot
I use a gaming laptop (Acer Predator Orion 3000) together with an Acer Predator X34A monitor. I also use a laptop (Macbook Pro)*, which I need for university, etc. Now I have 2 questions:
1. can this switch handle such a wide monitor? (34", 3440 x 1440 pixels)
2. will the signals from the mouse/keyboard be transmitted to the PC and monitor at the same speed as if I plugged them directly into the monitor, or should I expect an increased reaction time? (This would be particularly relevant for games).
*I am aware that the laptop needs additional adapters to connect it to the switch.
Hello Donbiva,
I have to split your question into 2 answers.
1) Do your two laptops have a DP output? If not, this KVM switch is not recommended. It only works if the DP signal is correct.
If, on the other hand, you only have an HDMI output on at least 1 laptop, then look for an HDMI KVM switch.
2) Surface keyboard and mouse.
These are both Bluetooth devices that can be connected via a dongle. If you didn't get a dongle with the keyboard/mouse it will be difficult.
I don't know of a KVM switch with Bluetooth yet, but it will probably be available. But then it will be far above the price range of this KVM switch.
