How do I get my Dell Inspiron 3030 to display 3840x2160 resolution?

[Atlantis1]

How do I open up the option to allow my Dell Inspiron 3030 to display 3840x2160 resolution? I read that the display port has the capability. I bought a 4K DP to HDMI cable. I updated my graphics driver to UHD Graphics 770. My monitor is a 43in 4K TV. The highest resolution available is only 1920x1080. 

Thanks for the help!

Go into Settings and select System. This should open the Display settings. If not, select Display as well. Maximize the window and then take a screen shot (or photo using smartphone). Attach this picture to a response post.

Please provide the brand and model of the TV.
Can you provide a link to the DisplayPort > HDMI cable?

This is a link to the DP to HDMI cable.

The TV is a Pioneer 43in 4K. Its not the TV because the Inspiron 3030 doesnt allow the option to use 3840x2160 resolution on other TVs. I have multiple PCs that have the 3840x2160 and they can run on the new TV.

From the description of the adapter cable, I gather that it is a "passive" cable, which also seems to fit with the fact that the mode is specified as 3840 x 2160 @ 30 Hz. This corresponds to what dual-mode DisplayPort (DP++) outputs on computers can do. Dual-mode means that the graphics card’s display engine and the connector are capable of outputting a video signal via both the DisplayPort HBR2 protocol and the HDMI protocol using TMDS. With the latter, the TMDS clock frequency would be limited to 297 MHz, which corresponds to 4K @ 30 Hz with CTA-861 video timing.

Dell Inspiron 3030 is a Desktop computer, is this correct?

According to the user manual on page 17, the video ports have the following properties:

In my opinion you can run this computer on a 4K TV, but since there is no mention of dual-mode (DP++) support anywhere, I assume you will need an ACTIVE protocol converter. I would recommend this as it has been proven to work (I use it myself at 4K):

It's not exactly cheap but it's future proof with any PC with DisplayPort 1.4a to HDMI 2.1 FRL up to 4K @ 120 Hz or 8K @ 60 Hz.

Awesome. Thank you. I just overnighted the new cable. I will test it tomorrow. Thanks again.
