Question about UltraSharp U4021QW - 514368

I have 2 pcs and a notebook on the monitor. I have 2 logitec multidevice keyboard miniusb dongles, so that I can switch the mouse and keyboard (pc2 and monitor each have one of the logitec usb receiver minidongles), i.e. between the notebook and the dongle in the monitor (pc1 and notebook), the monitor switches the mouse/keyboard, and when I use the second pc, I switch the mouse and keyboard on the

logitec multidevice to the pc2 dongle. If you only have 2 devices on the monitor, you don't need a multidevice mouse/keyboard, but with my third device (pc2 - a very old windows xp pc that is rarely used) it is quite practical. I would buy the monitor again. The only criticism is that the on/off button is at the back and you have to contort your hand a bit to get to it from the front. On my 16:9 32" 4k Dell, the on/off switch is still at the bottom of the frame - that's much more practical. The company notebook (hp elite something or other - approx. 3 years old) can fortunately support 5k resolution, but only in 30hz (adjustable in the intel graphics driver) - I hadn't thought about this and had feared that the notebook wouldn't be able to support 5k/2k resolution, as I only found everywhere that the hp notebook can only support 4k (in 60hz). I never want to program in resolutions lower than 5k/2k again. Had the 32 inch 16:9 dell before which was also ok but with the 5k/2k 21:9 40 inch just right for 2 windows side by side and in height enough pixel for more lines of code.

Yes, that is theoretically possible. To do this, you have to install the Dell Display Manager on both Windows devices. You can then define a key combination in the input manager to switch to the other source. The whole thing has a catch: if the other PC is not started or the Dell Display Manager software is not loaded, you still have to switch using the control button on the display.

One PC can be

connected via USB-C, the other via HDMI + normal USB cable (A-B). What's really great is that the monitor has an RJ45 network connection. This means that the PC that is connected via USB-C has a real LAN connection. So there is really only one USB cable to the PC or notebook.

I would buy the monitor again immediately. But it could be even bigger... ;-)
