Thanks in Advance
You willl be happy to know you are no alone. I have experimented with the SEIKI 4K monitor and a few cards. Here are my findings :-
1. Radeon R5 230 (ASUS 1GB Fanless)
- Does not work on Windows 7 (I believe issue is Catalyst Control Panel - 4k resolution not showing up). R5 230 SL-1GD3-L
2. MSI Radeon HD 5450 (MSI 650Mhz Fanless)
- Works on Windows XP but NOT in Windows 7 PC (with APU)
3. MSI Radeon R7 260X
- Did not work on Windows XP (but Catalyst Controller drivers were ready for XP. There are updates now)
4. MSI Radeon R7 240 (with fan low profile 2GB DDR3)
- Works in Windows 7
5. XFX Radeon R7 240
- Works on Windows XP - but had to return due to fault.
Radeon HD 5450
Those who say you need a high-end card for 4K, would be surprised to learn a MSI Radeon HD 5450 supports 4k under Windows XP. Been using it for months, works brilliant.
However, when I took the same Radeon HD 5450 Graphic card and put it into a Windows 7 PC, it did not work in 4k mode. The difference was the Catalyst Control Center software. In Windows XP it is a different Catalyst Control Panel compared to the Windows 7 edition. In Win 7, it did not give me the option of selecting the 3840 x 2160 resolution. So the limitation is the software not the hardware!
So the MSI Radeon 5450 hardware is
capable of 4k support. (Exact card: MD1GD3H/LP)
AMD Radeon R5 230
R5 230 is supposed to support 4k
AMD Web spec says "4K Resolution Support? " Yes (4K60 SST or MST).
However, there is a footnote which says " Supported resolution varies by GPU model and board design; confirm specifications with manufacturer before purchase.
Radeon R7 240
The safest choice is the R7 240 range.
For those experimenting. You need to do 'Detect Displays' (so the card knows the TV can support 3840 x 2160 resolution). (select 30Khz).
