Mixed resolution Eyefinity

Blog Post created by samantha.davis on May 12, 2015

While 4K monitors continue to proliferate and, we hope, become more affordable, it’s still hard to beat a multi-monitor setup1. That’s especially true if you already have a monitor or two; combining them and buying one or two HD monitors to make a 3-screen setup can be a more cost effective route to getting way more screen area than a single 4K panel.2


Many gamers have made the leap and gone out to buy two HD monitors to flank the one they already have. Now even more gamers can enjoy the benefits from AMD Eyefinity Technology, and everyone can have access to the wider variety of display possibilities Eyefinity offers.


The new capability in Eyefinity we’re talking about is support for mixed resolutions, and the easiest way to explain it is with a picture:



In the photo above we have an ultra-wide 2560 x 1080 monitor with standard 1080p monitors on either side, giving an expansive, immersive 6.9 megapixels (6400 x 1080) of gaming for about $650 all-in (figuring $150 for an HD monitor and $350 for the wide screen one in the middle of this photo). That’s little more than the cost of one of the cheapest 4K screens. And the upgrade cost can be even lower for gamers who already have one monitor to start with.


Less elegant but equally functional arrangements like this 4480 x 1024 setup are possible using pretty much whatever monitors you have laying around.



As you can see, mixing monitors of different resolutions can work great! And mixing monitors of different sizes isn’t any different.



The diagram on the right shows what happens when you mix and match different sized monitors: you have a choice. You can shrink the game frame so that it fits within the screen area available, leaving a little extra unused screen hanging off the top or bottom.


Alternatively, you can expand the image from edge to edge in every direction, automatically creating ‘hidden’ areas of the picture. The picture’s never stretched or squeezed; it just looks right, thanks to this flexibility. That’s entirely new in the world of mutli-screen PC gaming.


This opens up a whole world of new possibilities to gamers, and probably a new lease on life for many a dusty, discarded screen.


All AMD Radeon™ R7 Series and R9 Series graphics cards support mixed resolutions. To try it out, you first need to download the latest AMD Catalyst™ Driver. Making it work is a simple one-click setup, so give it a try.

But wait, there’s more!


Mixed resolution with AMD Eyefinity Technology isn’t the only thing that’s new in display tech. Also making news is the recent announcement by VESA that Adaptive-Sync will be part of the DisplayPort 1.2a industry standard specification. Close followers know what that means for FreeSync technology developed by AMD.

  1. AMD Eyefinity technology supports multiple monitors on an enabled graphics card. Supported display quantity, type and resolution vary by model and board design; confirm specifications with manufacturer before purchase. To enable more than three displays, or multiple displays from a single output, additional hardware such as DisplayPort™-ready monitors or DisplayPort 1.2 MST-enabled hubs may be required.  A maximum of two active adapters is recommended for consumer systems. See for full details.
  2. The starting price for a 4K monitor is currently USD $600. Source:
