Thumbs down Seiki SE39UY04 39-Inch 4K-- But it will display 1920x1080 max! NO 4K

I am using a Radeon R5 230. Loaded the latest stable drivers. Have tried 3 different cables and 2 different HDMI ports. Called XFX they said the card should work try a different cable which I have already done. They said call Seiki.
Called Seiki no answer. Do I need to up date the firmware? Anyone got this combo to work?


Thanks in Advance

Have you tried locking the refresh on the computer to 30hz? Your tv can only handle 30 at that resolution but your card can put out 60.

Well that video card your referenced in your original post looks like it might only do 2560x1600, so you're never going to 4K with it.

There's no reason to think that video card will support 4K. I bought one of these and can only get 1920 x 1080 from the video card on my main PC, an XFX card that cost $30 and uses a Radeon 5450 processor

I have another computer with a built-in GPU that uses something like an AMD 8750. That should be able to output 4k but only though the DisplayPort with a DisplayPort-to-HDMI adapter. I wasn't able to get 4k with that but I only spent about 5 minutes trying, so that's not surprising.

I got the adapter at MicroCenter and asked the sales rep about what kind of card I would need to get 4k video directly from the card. He confirmed that video cards capable of 4k would start at around $100. You will probably need at least a 7 series, possibly minimum 8 series GPU to get 4k.

Only the latest and greatest cards can do 4K over HDMI. That means high-end/mid-range cards from the past six months or so. Nvidia's Maxwell and AMD's latest with DisplayPort or HDMI. Those start at $150 and go up from there.

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.

Secret
For those experimenting. You need to do 'Detect Displays' (so the card knows the TV can support 3840 x 2160 resolution). (select 30Khz).
