HD graphics 530 Max Resolution (HDMI) 4096x2304[NAME] Dell manual is correct.  HDMI is 1.4, not 2.0.  If it were HDMI 2.0, it would support 4k @ 60hz. While HDMI 1.4 was introduced to handle 4K of video, HDMI 2.0 delivers 50 to 60 frames compared to 24 frames from HDMI 1.4. Re: an Optiplex 7050 unit modified to meet HDMI 2.0 standard you would need to add a discrete video card that supports HDMI2.0. Re: I would like to know whether this machine is able to drive a QHD monitor at the resolution of 2560 x 1440 @ 144Hz.   For 144Hz at 1440p, you will need at least HDMI 2.0 or DisplayPort 1.2.
Hello all, I have purchased a refurbished Dell Optiplex 7050 with a sixth generation Intel Core i7-6700T processor, which has an Intel HD 530 graphic processor. Before purchasing a monitor,  I would like to know whether this machine is able to drive a QHD monitor at the resolution of 2560 x 1440 @ 144Hz.    Since the machine has not been delivered yet, at the moment I am unable to provide test data or part numbers that could help in finding an answer. Unfortunately, he documentation on the Intel website at [URL] specifies only a max resolution of 4096x2304[NAME], but says nothing about the achievable refresh rates at lower resolutions. There also seems to be some discrepancy about the standard of the HDMI video output, which is shown as 1.4 in the Dell user manual (and which would not allow the resolution and refresh rate pair of my inquiry) and as 2.0 in the vendor spec sheet (which would). Is it fairly common to come across an Optiplex 7050 unit modified to meetHDMI 2.0 standard, or should I chalk this out as a vendor's inaccuracy? Not a major deal as the 2560 x 1440 @ 144Hz signal can be sent through the displayport 1.2 connector, if the Intel HD 530 is able to generate it. Thanks in advance to all those kind enough to share their knowledge with me
Can the Optiplex 7050 produce a video resolution of 1440P at 144Hz?
