Help needed with R9 280X - dual monitor connections

post #1 of 13
Thread Starter 
Hey guys, I've been looking for a GFX card to upgrade my HD6870. I've already decided to go with an AMD R9 280X, I just don't know which specific brand to buy yet.

Right now, the MSI 280X seems like the best option to me as it comes out best in comparison tests and is one of the cheapest cards. But I use 2 monitors and the MSI 280X only has these connections:
Dual-link DVI-I x 1
HDMI (version 1.4a) x 1
Mini DisplayPort x 2

The monitors I use are a BenQ XL2411T (144hz) and a NEC LCD22WV (old).
The BenQ has: D-sub / DVI-DL / HDMI x 1
The NEC has: VGA 15 pin D-sub x 1

Would I be able to use my NEC screen with the MSI 280X and use my BenQ at the same time, with 144hz refresh rate? I read somewhere that a newer type of HDMI supports at least 120hz, though I couldn't find a clear answer to that. I am willing to purchase converters if needed.

Thanks!

280x is a great card if you can find one without an inflated price. The bitcoin miners have descended on the 7xxx cards, and the pricing has become ridiculous.

@Bombastinator, Thanks for the reply but my question was about the compatibilty with the MSI card and my 2 monitors, I'm 100% sure that I'm gonna get the 280X but just not which brand yet. I edited the OP for clarity.

I can get them for these prices btw:
Sapphire Dual-X: €261,-
Club3D: €267,-
MSI: €270,-
Gigabyte (+BF4): €271,-
Sapphire Vapor-X: €276,-
Asus: €278,-

I don't mind paying a small premium for a better brand.

ok. 280x usually has 1 dvi, 1 hdmi and a coupel display ports. you can get a hdmi-dvi or hdmi-vga cable without a lot of trouble, so you should be able to connect your monitors.

Alright, correct me if I'm wrong, I could buy a 1.4 HDMI cable that supports 120hz (not 144hz?) for my BenQ and then connect my NEC with a Dual-Link DVI-I to VGA converter?

I am almost certain that HDMI will NOT allow for 144hz. You must use the Dual Link DVI for that. I would connect the BenQ via: Dual Link DVI and purchase an adapter....VGA to HDMI or VGA to mini display port. Good Luck.

That should work, but as you said the BenQ will be limited to HDMI 1.4 Specifications.

i doubt it will support 120hz. probably only 60hz. might though. d sub could be anything from 9 pin serial on up. All "d sub" means is it's got a D shaped ground shield and is less than about an inch long. Even miniusb is arguably d sub. vga is as well. What port is it exactly?

As for the disply ports you can get vga-displayport if you want. it's not a question of 'can you hook them up' it's a question of how much you want to spend on cables.

Thanks a lot for the quick replies guys smile.gif

I've found multiple sources that say 1.4 supports 120hz (not 144hz), of which the official website: http://www.hdmi.org/manufacturer/specification.aspx
1920x1080p @ 119.88/120Hz (Side-by-Side(Half), Top-and-Bottom

All the converters for VGA that I've found on the internet are pretty expensive (around €30,-). So I'd rather not have to purchase one of those; I've already got a DVI-I to VGA converter.
So the config I mentioned in my last post would be my best option right? biggrin.gif I would only have to purchase a HDMI 1.4 cable.

@Bombastinator, the D-Sub is a VGA.

heh. i guess it comes to the definition of 'old' my 'old' monitors with dsub connections are suns. Good chance they're older than most of the people who post here.
