Hello,
I have a GTX 1050 SC (02G-P4-6152-KR) and would like to run a 4K TV over HDMI with it. I have tried two TVs and three different HDMI cables that are supposed to support 4K @ 60Hz, but the driver only shows 30Hz. Trying to force a custom setting results in an image the TV won't sync to. I can't find anywhere which says if this card supports  over HDMI, but I assumed it would since the chipset does. Can anyone confirm if they have this combo working at 60Hz?
 
I am running it on an older i5-2400, so it is in a PCIe x16 Gen 2 slot. Could this be the issue?
 
Thanks.

Hello,
 
as HeavyHemi said above, the card is capable of running 3840x2160 @60hz via HDMI.
 
Can you please let us know the displays/tv's you are trying to connect to?
 
How long are the cables you are using?
 
In the Nvidia control panel, are you picking a "UHD, HD, SD" resolution or a "PC" resolution?
 
Let us know these few details and we will have better ways to assist.

I have tried two 6' cables and one 15' cable. The only other system I have which supports 4K is a MacBook Pro, but it is limited to 30Hz over HDMI, so cables are a possibility, as I cannot confirm these cables do work at 60Hz. TV details in previous reply.
I chose a UHD resolution - 3840x2160, and only saw 24-30Hz as the available refresh rates. I believe the PC resolutions topped out at 1920x1080. The TV is back in the box now as there were enough other things I didn't like about it so I will return it. I just want to see something work at 60Hz so I know for when the right display comes along. I did check for firmware updates on the TV (it has online updates) but there were none.
 
Thanks.

Welcome to the forum. The gen slot doesn't matter.  The GPU has HDMI 2.0b,() so it is capable of doing 4K at 60hz. I need to know which specific 'TVs' you tried to use. They must support HDMI 2.0.

Thanks for the quick reply. One of the TVs was a Seiki SE48UXC4t, which had 3 HDMI ports all labelled 4K 60Hz. The other was an RCA 49" 4K, but it did not state 4K 60Hz in the specs or on the ports. I may just have to borrow a known working TV or monitor just to confirm I can get the combo working at home before I try any more TVs, as unboxing & boxing TVs is a major pain. I am looking for a 40-49" TV for photo editing, as they are currently lower cost (<$400 CDN) than a 28" 4K monitor, and I find 28" still a bit small for 4K.
 
Thanks

it is very possible that both displays you listed will only support UHD @60hz while using ycbcr color (4:2:2 or 4:2:0 Chroma)
 
I do not think either of the displays you were testing support UHD @60hz on 32 bit RGB color.

Ok, that makes sense, and I cannot reduce the colour bit depth in the driver - it is set to 32bit - so this would explain it.
I guess I need to keep searching for an affordable 4K TV that also supports 4:4:4 at 60Hz, or break down and get a 28" 4K monitor like the Asus. However, I don't find 28" that much bigger than the 24" 1080 and and 21" 1600x1200 that I currently use - (the 21" offers about 1" more vertical) Getting a 40"+ TV will allow me to go with a single monitor for photo work.

Actually, you can adjust the color output from the driver control panel but its not worth it if you are going to be using this display as a PC monitor.
 
RGB 32 bit color is a must in my opinion if you are using a tv as a monitor, especially reading text.
 
with more and more 4k tv's and monitors becoming available the prices have decreased substantially and continue to drop. Im sure you'll find something.
