Dual ASUS VG248QE monitors, only one DVI-D port on my GPU. What other connections support 144Hz?

[andrewdill926]

I have had a ASUS VG248QE monitor for a few years and have been pleased with it. I just got a second one. When I went to hook it up I noticed I only have one DVI-D port on my GPU. I also have a DVI-I and HDMI port. It would be super easy to connect the 2nd monitor if I had another DVI-D port ... but I don't. So of the remaining ports do any of them support 144Hz refresh? Or am I stuck using an HDMI cable and only getting 60Hz?

Thanks

** Edit, I noticed I had a tiny black cover on another port I always assumed was an HDMI port, but it is a displayport ... the ASUS VG248QE monitors have a displayport connection as well, so I assume if I buy a displayport cable that should work for the 2nd monitor.

Actually, the DVI-I port (which has both digital and analog pins/signals) of your GPU is compatible with DVI-D cables (which only transmits has digital signals) due to how the pins are arranged. This configuration means that only the digital signals coming from the DVI-I port will be sent to your DVI-D monitor.

The photo below shows you the male connector of a DVI-D cable (top photo) that can be plugged into a female DVI-I socket (bottom photo):

Your VG248QE monitor does support 144Hz at 1920 x 1080 resolution using DVI or DisplayPort and only 60Hz using the HDMI (see page 3-8 of your manual here: http://dlcdnet.asus.com/pub/ASUS/LCD%20Monitors/VG248/VG248_English.pdf?_ga=2.154983984.907747820.1504953145-643997671.1502818833).

So, before buying a DisplayPort cable, you may want to try with an existing DVI-D cable (but this time plugged into the DVI-I port of your GPU) if 144Hz should work in that configuration. Otherwise, DisplayPort is your next option and should work at 144Hz.

Dvi-i might only be single link, 144hz dvi needs to be dual link which the dvi d in the gpu is. Need to look at the spec sheet of your gpu to find out.

Its a safe bet going displayport.

1920x1080* (DVI/DP) 144Hz
Horizontal 158.11KHz (2D)

You must select one of the “*” timing for enabling 3D or 144Hz feature with a compatible NVIDIA-GPU graphic card via Dual-link DVI cable connection.

That's what manual says. I don't know why it would be limited to "NVIDIA-GPU graphic card via Dual-link DVI cable connection" when the Resolution Frequency has both DVI/DP listed.

The bet solution is to use a display port.

It would be super easy to connect the 2nd monitor if I had another DVI-D port ... but I don't.

DVI-I is just a DVI-D + VGA combo port. It can still do everything a DVI-D port can do.

You are right, use the DVI and DP. Both support 144hz.
