Review on High-Quality DP to HDMI Adapter [3-Pack], CableCreation 1080P Gold Plated Displayport to HDMI Converter Male to Female 1.3V Black by Jeremy Tang

I bought two new Samsung monitors that support resolutions up to 2560x1440. There is already an HDMI cable connected to the monitors via a stand, so I connected the first monitor to the HDMI connection on my graphics card (NVIDIA GeForce GTX 970). Since I only had one other DP port, I decided to use an adapter to connect the supplied HDMI cable to the DP port on my graphics card. Unfortunately, it could only display 1920 x 1080. After a few minutes of troubleshooting I opened up the stand and plugged in the DP cable and there it is, both monitors are now 2560 x 1440.
