Cable Matters HDMI to DisplayPort Adapter (HDMI to DP Adapter) with 4K Video Resolution Support

I have two PCs hooked up to a new, 2K monitor. This is one of the cheapest 2560x1440 monitors you can buy... the BenQ gw2765ht. The monitor works best with DisplayPort connections. I tried using HDMI with my Windows PCs and it works, but the brightness and contrast are wacky. Light greys on white (as in menu highlights) are absolutely invisible. So what I'm saying is that my monitor demands a DisplayPort connection.So I bought a KVM switch that uses DisplayPort exclusively. My gaming PC has a DisplayPort connection, so that's fine. But my desktop does not because it is a tiny micro form factor Alienware machine. It only has HDMI in the back. The answer was this beauty of a cable.It turns an HDMI port into a DisplayPort and it works flawlessly. I plugged it into my Alienware and then plugged my KVM DisplayPort cable into it and BOOM... it works absolutely perfectly. The image on the monitor is crystal clear and pixel perfect. There is no indication that any sort of signal translation is occurring or anything like that. It just works.It is quite expensive as a small little cable, but dang it works exactly as I was hoping.

I run with two KVM's to support 4 Monitors. I have a work laptop and I am using multiple USB to DVI to HDMI adapters along with the HDMI port on the laptop. My PC has 3 Display ports and 1 HDMI connection.Previously everything was running through HDMI KVM's, but the best frame rate I could get was 75 since that was the limitation of the KVM's. I bought a new Display port KVM to get the frame rates my video card could produce and I couldn't get it to work with my laptops connections. Turns out that HDMI to Display Port cables are unidirectional and would not work. I bought two of these adapters to (hopefully) run my two primary monitors that I am using through fast display port for my home PC and they worked...mostly.My 27 inch monitor worked perfectly once I gave these adapters enough USB power. Without strong power, I was getting blackouts and strange blue lines. Connecting it to a strong USB power source fixed that. I have a 35 inch display that natively is at 3440x1440. My home PC that is display port through all connections works fine. My laptop when running through the other adapter cannot display that resolution properly. It shows that as 2560x1440 and has dead space on the top and bottom of the display. Good enough. It is working and I can live with that one being a little bit off since I have full display port to these two Monitors on my home PC. Overall these worked great with this KVM and I am back to working with all of my displays.

No issues converting HDMI output from my laptop to DP port on my monitor. The adapter has a USB cable that must be connected to power (either a usb port on your computer or a charger plugged into the wall)

This review is for the HDMI to Displayport adapter. This thing is awesome!! Keep in mind I've only had it for like 2 days. Surprisingly it works for a 1080p 144Hz monitor and allows it to run at 144Hz with 4:4:4 color. I believe this means the HDMI input is actually an HDMI 2.0 I tested and it IS HDCP compliant. I have not had any trouble with it so far. Literally connect and go. It is completely independent of the software, so you could use this to connect an HDMI Blu-ray player to a Displayport monitor. It does require 5V power from a USB port or wall adapter (not included). Tempted to buy another in case this one goes out or I need another somewhere else. Highly recommend!!!UPDATE: For my computer the adapter runs on the HDMI power alone, no need to connect to a USB port, but ymmv. I've been using this in conjunction with an HDMI switch for a week or two and sometimes when switching back an forth between PCs, I'll have to power cycle the monitor to get a picture back. This may be an issue with the one specific Windows 10 PC, since it only happens with that one computer. Also, it does not work with the Monoprice 2x1 Displayport switch. I'm guessing it is an issue with this converter, but not sure as each product works when used by itself, just not together.

Did exactly as advertised connecting my home office computer to DisplayPort Monitor.

This was used to connect a nice old Samsung SyncMaster S27A850D 27" 1440p monitor to a new computer with integrated graphics. The old monitor had display port and DVI but no HDMI. The new computer motherboard had only HDMI.I first tried an HDMI to DVI adapter. Unfortunately, they all seem to be limited to 1080p. My wife was not happy because she likes running her games at 1440p.The solution was this adapter. I also had to buy a 6' display port cable.I first made sure the bios was set to start with integrated graphics. Then I shut the computer down. I plugged the adapter's HDMI plug and USB power plug into the computer. I ran the display port cable to the computer. I started the computer, and voila, everything worked.Graphics quality is excellent, just as nice as with a discrete video card. 1440p is crystal clear.Also, this adapter is small, lightweight and not bulky. It easily fits behind the computer.It's a little expensive, but much cheaper than buying a new monitor.

I had to get this since my graphics card only had 3 displayport slots and a hdmi port. I had just gotten the valve index and it needed a display port but then I couldn't use the 144hz on my monitor since it's only supported through display port. So I looked around and found this. Works great with the usb plugged in I get the full 144hz and haven't had many problems. I only had one recently where I ran VRMark and the program crashed so hard that the display this was connected to was just black. It was still receiving signal but it wasn't displaying anything. After a restart it fixed it so I don't know why that happened.
