Samsung 4k TV showing as 1080p only on Win7 machine

[SirSaini]

Here's my set-up
1. Win7 desktop, Intel board - latest drivers.
2. New graphics card, Nvidia GT730 chip - latest driver. It is 4k capable.
3. New samsung 40" 4k tv. Connected via mini-HDMI port on graphics card. The cable is also HDMI 2.0 certified so 4k capable.

the TV shows as 1080p only, I don't see 4k. What am I missing? TV has no driver, I see is as 'generic pnp monitor'. Appreciate the help.

Also I have tried upgrading to win10, same issue. I rolled back to win7, no change.

Menu>Picture>Picture Options> Enable HDMI UHD for the hdmi port your pc is on.

Is this option on TV or on PC?
no such option in TV. I could only find UHD color in TV options which i turned on, no change.

Btw, I notice the driver on Samsung keep showing as Generic pnp monitor from Microsoft dated 2006, I bet this is the problem. I reinstalled driver couple of times, can't get this to change. My guess is this old driver has no support beyond 1080p, hence I don't see 4k option. I am still stuck.

GT750 will only do 4K@60 over displayport. Can't do it over HDMI. Get an Active adapter like this

this card (GT730) has 1 HDMI and 2 DVI ports, there is no DP port. So the adapter won't do much.
I am still stuck with 1080p only, would appreciate help to get 4k,

In that case, there's no choice except a new videocard. You can get a GTX-950 for under $140

The problem could be that your TV is not capable of 4K with full RGB. Try enabling chroma subsampling in nvidia control panel i.e. change colour output to Y'CbCr 4:2:2 or 4:2:0 or 4:1:1... anything other than Y'CbCr 4:4:4 or RGB which is full chroma resolution.
