Triple monitor setup - Cannot get third monitor to 144hz

[mherrera]

Hey everyone,

So I'm going for an all-out triple monitor setup. I have (3) Asus ROG Swift PG279q monitors, and (2) Asus ROG Strix 1080's (running SLI). These monitors are capable of a 165hz refresh rate and I would like to achieve that for all 3 screens.

Here's my predicament. The card has the following ports: (1) DVI (2) DisplayPort (2) HDMI
I am currently running two monitors with the (2) DisplayPorts, and one monitor with (1) HDMI port. None of these monitors have a DVI port, which leaves me stuck.

I've been doing a lot of research and seem to not be finding any solutions. I've read multiple forums saying I need an "Active Adapter" to run what I need. However, when reading the specs to those adapters, it mentions a limit of only 60hz to 1440p monitors.

My questions are, is there any adapter out there that can help me achieve 1440p 144hz? Is it even possible to get the third monitor to 144hz? Is there a way around this?

I appreciate the help in advance.

What resolutions are you currently achieving? I suspect 144Hz 1440p over DP and 60Hz over HDMI?

DisplayPort should get you 144Hz at 1440p....

HDMI 2.0 should be able to do it too, as far as the output from the card. The monitor itself though, lacks 2.0, so that takes HDMI off the table (at least as an input).

Your options:
DVI-D (Dual) to DisplayPort adapter
HDMI to DisplayPort adapter

I suspect (but can't confirm) that passive DVI-D (dual) adapters should be fine. The DVI-D (dual) signal is capable of 144Hz at 1440p, as is the port on your monitor..... so active *shouldn't* be necessary IMHO - there's nothing to convert.

HDMI 2.0 to DP would be ideal, but Im not even sure those exist...... it's much more common to go DP to HDMI.

You're correct about the monitors. 2 are currently running at 165Hz via DisplayPort. One monitor is at 60Hz via HDMI.

Would something like this work? https://www.newegg.com/Product/Product.aspx?Item=N82E16812400320&cm_re=DVI-D_%28Dual%29_to_DisplayPort_adapter-_-12-400-320-_-Product

Or this? https://www.newegg.com/Product/Product.aspx?Item=N82E16812119558&cm_re=displayport_to_dvi-_-12-119-558-_-Product

I know it's not the exact one to get, but generally that's what we're talking about, correct?

Sorry, I'm still slightly confused about what you said.

Neither of those would work, for a couple of reasons.
1. The first is DP to DVI. They;'re not bi-directional. You'd need DVI to DP.

2. Also reversed, and is DVI single link, so won'y carry the resolutions/refresh rate you're aiming for.

You'll also see an abundance of supposed "DVI-D Dual" adapters for cheap, which are in actual fact DVI-D Single, with the added pins for show only (outright false advertising). Genuine Dual cables are thicker than single, which is the initial giveaway that something isn't right.

The easiest route to go would be HDMI 2.0 to DP, which is a little pricey, but much more straightforward.

It's a little pricier, but it has secondary USB power (required) and Startech are reputable.

Alright, I'll give this a go and see what happens. Thanks for the advice!
