BENFEI Active DisplayPort to HDMI Adapter 4K@60Hz, Compatible with PC,Laptops, Desktop, Tablets, or DisplayPort Docking Stations, Supporting Eyefinity for Multi-Screen Gaming

Works well with a KVM switch that supports EDID emulation. I used it with a TESmart dual-HDMI switch, and a graphics card that has one DisplayPort and one HDMI output. This worked well to convert the DP output to HDMI, while not losing the EDID emulation. It does appear to get warm after several hours of operation though; I would not recommend packing it into a cramped or enclosed space.Just be careful that the directionality is what you want -- when using this with a KVM switch, this item is for the **source** side: plug the displayport end into your computer, and the HDMI end should mate with the cable running to the KVM's **input**. This will NOT do anything if you were to plug it into your monitor's DP port.(Unfortunately, the KVM itself was a disaster, so I still ended up returning this as it was no longer needed. But, this item works well on its own.)

Has been running flawlessly on a 2560 x 1440 70Hz monitor for over 4 years day in, day out.

I am always appreciative of a product like this. It's simple, straight forward and it does exactly as it should. I've had no issues at all, instantly worked without any problems. Definitely recommended. There are plenty of other products that I can't sat the same for. This one is great.EditOops so just a week ago this stopped working. No longer transmitted the signal. My PC was off, not asleep but off and I booted it up to a black screen. I checked the typical stuff and while doing so had run my hand along this to find it very hot to the touch. Far hotter that anything like it should be. Mind you this was in about a 1 time period after the PC was powered on. Not comfortable with it, the seller is great and would honor the warranty but I'd prefer not take the risk unfortunately. Live and learn.

Got this to replace a more expensive Club3D adapter that kept getting constant disconnects on every monitor I tried. Worked out of the box as expected, and at a much lower price. No more disconnects and headaches trying to get my set up to work

Great converter no issues

Note: This is for the Active DisplayPort to HDMI (4K@60Hz). I have a couple of Dell monitors I wanted to daisy-chain together. The primary display is a P2423DE with DisplayPort input and output connections, and the other one is a SE2416H with an HDMI input.The setup works well, provided you have a video card that supports it. An NVidia Quadro card will drive it, along with a Dell Latitude 5520 (via the USBC power/video port). Also, the monitor being driven in this manner has to be the last on the chain.A Lenovo T430 with Intel HD graphics will only drive the primary monitor, as the video subsystem doesn't support MST at all.

This worked perfectly to allow me to set up dual monitors (not mirrored- desktop is extended across both monitors). My graphics cards has 1 HDMI output and 3 DisplayPort outputs. I put my main monitor on the HDMI output and a smaller portable monitor I have for traveling in this adapter, plugged it into the first DisplayPort output, and extended the desktop across both monitors. The screen quality looks as good as it did when I had the portable monitor directly on the HDMI output. I'm sure this would work as well if I had two regular monitors instead of one portable monitor. This little adapter is great for the price.

I'm trying to use this with my HP Elitebook 850 G5, an HP UltraSlim Docking Station to go from DP in the dock, and an Acer X34 3440x1440@100hz. My DP port on the monitor is currently used up by my desktop with nvidia GPUs for G sync. Currently, my adapter isn't working from my dock. The DP->HDMI output is detected by the monitor, which will turn the backlight on, so it's now a glowing black screen instead of completely turned off, and then it'll turn back off. Sometimes I get a weird garbled image for a split second and then it turns off again. The whole time, my external monitor is seen by my laptop. No idea why this is acting up. Maybe bad adapter? The HDMI cable that I'm using with this has worked straight from the laptop into the monitor, but at reduced refresh rate. So I know the HDMI cable is functional.Edit: received replacement, still does exact same thing. Pretty disappointing but might be related to my dock, but product didn't work with any HDMI cables, so for some reason it can't handle the signal out of the dock. Shame.
