Alex,
In order to support two monitors
today, and the addition of a 3rd 4K monitor in the future----you'll need
a video card which supports 3+ video ports and at least one of those
ports must also support 4k output, i.e. 3840x2160 resolution, at a
minimum.
I research/review products, especially all the details in the SPECS, at the
manufacturers webpage, and that's usually after searching/comparing/contrasting similar
products on sites like MicroCenter, NewEgg, Amazon, as well as the
former FRYs Electronics.
The
Radeon RX 560 Richard Shaw suggested, has 3 video-out ports (1xHDMI
2.0b; 1xDisplayPort 1.4; 1xDL-DVI-D) and supports resolutions up to
4096x2160 (check!). Newegg has it for a price within your range. I
suggest reviewing the graphic card power supply requirements versus the
rest of the equipment in your desktop (i.e. total up all the watt's
consumed) and ensure your desktop power supply sufficiently exceeds that
capacity.
I purchased a pair of 4K monitors early last year to use with my new desktop. I choose the Samsung - UJ59. Great 4k resolution at 32" in size, shop around for price as you should be able to secure one for $300-$400.
As for native open source drivers on Radeon equipment I cannot speak to that. My preference is for something out of the nVidia family of products as their drivers for Linux (Fedora, Red Hat, Centos) have just worked whereever I've used them (at work and at home; physical systems and virtual). One card to consider would be the GIGABYTE GeForce GTX 1050 TI N105TOC; it is very close to within your price range, has 3 video ports like the Radeon RX 560 card and outputs resolution up to 7680 x4320.
Thank you.
R,

Hi,
I have about $300 to spend on a new video controller for my desktop.
I'm using f33 with Xwayland and GNOME. I currently have two 27"
monitors and plan to get a third 32" 4K in the coming months. I have
an i7-8700 3.2Ghz on an Asus PRIME Z370-A with 64GB.
I use my desktop for basic photo editing, playing videos, and basic
office/browser work. What recommendations do you have? Here's my
requirements:
- native open source drivers
- supports at least three monitors
- PCIe x16
- support for 4K
- HDMI output
- audio not necessary
What other specs should I consider? I currently have an old Radeon
HD-5770 but I'm starting to find playing video within a browser is
less than fluid.
$ lspci -k | grep -A 2 -E "(VGA|3D)"
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] Juniper XT [Radeon HD 5770]
Subsystem: PC Partner Limited / Sapphire Technology Device e147
Kernel driver in use: radeon
Thanks,
Alex
