Feeding a 4K monitor - new motherboard or graphic card?

kennethsross · 10 Mar 2015 at 11:01

Really looking for some advice here. Thanks for any help.

Under my desk, I have a box of PC components - a 4770K, 16GB of DDR3 and an MSI z-87 G43 motherboard. Just needing to get round to building them into a case.

I recently bought an AOC 28" 4K monitor. MSI board claims to deliver 4K video (well, ultra-HD really) over HDMI.

Will this work fine with the onboard graphics on the 4770K / motherboard? I'm not into gaming; just mainly office apps, image editing and a bit of audio / video editing. Would also want to watch blu-ray videos.

So I'm wondering - do I build up what I've got, and then buy a GTX750ti if the board doesn't come up to scratch?

Or do I sell that unused motherboard on eBay and buy a Z97 m/b with DisplayPort (which is where I understand the monitor likes to get its signal from)

Appreciate any thoughts. Should add, OS will be 8.1 64bit

TIA

4k hdmi is 30Hz, display port is 60, as your not gaming your first option of getting a gtx if your mb driven output isn't snappy enough is the way to go.

if you really want display port the cheapest gfx is this:
YOUR BASKET
1 x Sapphire Radeon R7 250X 1024MB GDDR5 PCI-Express Graphics Card £65.99
Total : £75.59 (includes shipping : £8.00).

But if you are just office I can't see the 30hz being an issue over hdmi.

Thanks, Pooker.

I'll need to research that. Some reviews of the monitor suggested an issue with ATI drivers, but it may well be sorted. That card certainly looks cheaper than a 750 from Nvidia.

Thanks, Lude and Pooker for your comments. So I guess i'll build it with the board I have, see how I get on with HDMI and go down the new graphics card route if I'm not happy.

From the manual of your mobo:

1x HDMI® port, supporting a maximum resolution of
4096x2160@24Hz, 24bpp/ 2560x1600@60Hz, 24bpp/
1920x1080@60Hz, 36bpp

I'd be tempted to build it and see how it goes. If you're not happy with it, grab one of the cards above, and I'm sure you'll be fine.

*edit* Didn't see your last post there, derp.
