Question Why doesn't my GTX460SE support 4K output?

[zijin_cheng]

My friend gave me his old computer with a GTX460 SE, which I'm setting up as a mediacenter for my 50" 4K TV.

The video card is connected to the TV via DVI to HDMI adapter, however it only outputs 1080p maximum. How do I get it to output 4K?

Latest drivers installed, CPU is a Phenom II X4 955 with 8GB RAM and an SSD.

That card is ancient! GTX 460SE can do up to 2560x1600. I would get a cheaper newer card like a 1030.

As said its an old card. Look for the cheapest 1030 or RX550 / RX560 card you can find. Those are the newer lower end cards and can do 4k video fine. Not 4k gaming of course.

And I think that's only over DVI-D DL connections, I don't think that using a DVI-D to HDMI converter (only one TMDS, not both) will do much over 1920x1200, even that's iffy with NVidia GTX 460 cards, if you want audio too over the HDMI. (I have experience with that personally.)

A used GT630 (Kepler) or GT730 (Kepler) will do 4K UHD resolution, at reduced color-depth.

Otherwise, you'll want a card with a true HDMI 2.0 output, which starts at NV Maxwell V2 GPUs, as well as AMD Polaris. So, get a GT1030, or an RX 550/560.

You need HDMI 1.4 for 4k, but it only supports 30Hz at that res, you will need HDMI 2.0 for 60Hz 4k.

GTX 460 supports neither, and is limited to 2560 x 1600

Not true, my Zotac "Zone" GT630 (Kepler, 384CC) 1GB DDR3 GPU(s), will do 4K UHD @ 60Hz (as verified by my display), over HDMI 1.4. They won't do it at 4:4:4, you do need HDMI 2.0 bandwidth for that. But strictly 4K60 can be done over HDMI 1.4.
