I already purchased an R9 Nano, but this could be an alternative... although I am not really sure why someone would buy this over the R9 Nano unless they specifically needed 5 to 8 monitors @ 30hz. At first glance, the R9 Nano is shorter, and far more powerful than this card. And same price.
But I couldn't find any benchmarks comparing the two head-to-head.
fwiw, I am in the market for a new monitor (currently using a 2007 era Dell 19" widescreen monitor) and started off doing research on 4K monitors. I came across this ultrawide monitor review where he makes a compelling argument against going 4K due to scaling issues in Windows. The review is a bit dated so there are likely newer improved models, but I have been threatening to order one of these ultrawides. Keeping in mind that the wife is going to be shaking her head that I paid this much for a monitor that will not improve work/trading performance.

Looks ilke a pretty good monitor....
There are no scaling issues with Windows 10. I think since Windows 8.1, it's not an issue. With Windows 7, yes.
If you buy a 40 or 42" 4K monitor I think it's a great fit for trading (and I am using 40's). If you are doing something like a 27" then I think it's a waste for trading. Traders don't need density, we need resolution.
27" monitor is too small to be useful for trading, and 4K is a waste at that size because you'll have to scale everything so large to be able to read it. 40" is the sweet spot, not less.
Hey guys I'm considering upgrading to a 4k 40" monitor I currently have a 17" laptop a 27" and a 24" I'd probably have everything I need on the 4k 40" and my laptop would pretty much become a desktop.
I've narrowed it down to a Samsung 6500 or 6700 series.
MSI Slim GS70 2OD-002US Intel Core i7-4700HQ 16GB Memory 1TB HDD 128GB x 2 SSD Super RAID0 NVIDIA GeForce GTX 765M 2GB 2 x Mini Displayport 1xHMDI Connect up to 3 Monitors 17.3" Gaming Laptop/Notebook Windows 8 Thinner than Razer Blade Pro (Upgraded to Windows 10)
Questions:
Is my system adequate to get 4k at 60hz? 4:4:4? any advantage on the curved 6700 Samsung series over the flat 6500 series?
And wouldn't recommend it as a monitor if:
a) you want auto power on/off like a normal monitor, instead of manual using remote
b) you plan to have more than one of them connected
If neither of the above apply to you, then I would recommend the TV. It's excellent.
I, however, will relegate it to other duties (probably will become my Bloomberg office TV) and plan to replace it with (3) 4k 40" displayport capable monitors.
4:4:4 60hz is not really applicable to trading mind you, so it likely isn't a deal breaker. I wanted 60hz just because I prefer the better refresh rate on my eyes. If you are asking if your GPU can handle 4K for trading, the answer is yes according to the specs I found, it supports 3840x2160.
dont believe anything you hear and only half of what you see
