RX 480 - Dell U3011 - Newbie Looking for Full Resolution

[robkellysound]

Hello,

I have a HP Omen 870-214na. It has a Radeon RX480 and I think it ha Intel Iris Plus Graphics 640; I can only use one of those at a time.

Neither can give me 2560x1600 that the Dell U3011 runs at.

As I am just not in the know; can this graphics cards run this resolution using a HDMI 2.0 cable? The RX480 also has a Display Port slot, but I do not have a cable to test it.

Thanks!

You can get 2560x1600 with an HDMI 2 cable as long as both graphics card and monitor support HDMI 2. I think the card does support HDMI 2. Not sure about the monitor.

If you increase resolution above FUll HD you have to lower refresh rate I think.


A DVI-D Dual Link cable will work just like a DisplayPort except it has no audio on it.

According to this review of the monitor:

https://www.anandtech.com/show/4070/dell-u3011-review-dells-new-30-inch-flagship

It has a HDMI 1.3 which is capable of 2560 × 1440 at 60 Hz and not a version 2.0 or higher HDMI.

The monitor has two DVI-D dual link ports, some Rx 480s don't have DVI-D ports, if it does have one you can use a dual link DVI-D cable for that resolution without audio. If not go for a DP cable.


The specs I found here says HP Omen 870-214na has Radeon RX 580R (4 GB):

Maybe your revision has RX 480.

Dang it, I never checked if the screen itself was HDMI 2.0; good shout there, thanks!

My card is an RX480 according to Device Manager and it has three of the larger display port sockets along with one HDMI.

The RX contributes some unwanted fan noise into the room; I am a sound engineer and need it as quiet as possible.

Would a HDMI to DVI-D Dual Link adapter, if there is such a thing, work? That would be off the basis that the internal Intel GPU can do it. the second screen I run is just at 1920x1200 and I have a HDMI to VGA adapter for when I use that card.

As far as sound goes you might look into Arctic Coolings GPU coolers. They use a large slow turning fan, and huge heatsinks.Sometimes this creates a 3 slot wide GPU though.
Sound specs are at their website. For some cards they offer no fan coolers also. There are also passive CPU coolers. the Thermalright Macho, and Macho 120 are often used without fans for normal computing. I think Silverstone has some too.

With that port configuration I think it is basically a reference RX 480 and I think those have a single fan which in order to lower temps has to spin at higher speeds than cards with say larger heat sink and/or two fans.

If you want a quieter card I think you can think about maybe swapping it (if an option) with a RX 480 from 3rd party manufacturers which usually tend to run more quietly than the reference model. I think the quietest one is MSI RX 480 Gaming X which runs at 31dB under load:

However this card requires an 8-pin PCIE power connector from the PSU. That may be an issue.

There are passive and active adapter but I don't really know a good one that would work to suggest. Here's one:

But I really don't know about their build and signal transfer quality.

After all I think the easiest and maybe the cheapest (without the hassle of adapters not doing what they should) is getting a DisplayPort cable at around $10 if indeed the monitor has that DisplayPort it's supposed to have and I saw in that AnandTech review I linked.
