I'm talking four 27'' or two 49'' monitors as a 16:9 curved monitor with a 5120x2880 5k resolution. Perhaps options in both 1000R and 1800R. As a professional trader that's what I would like. It's much more practical than two 49's. Hopefully Samsung can be the first to make it happen!
You should be looking at what the graphics card makers can offer aside from the monitors that would show the results.
A few Google searches for 5k and 8k resolutions reveal a lot of info.
