4K 60 Hz on Vizio E43U-D2

[idata]

I am trying to get my laptop to display 4K resolution @ 60Hz. I just bought a new Vizio 43" 4K TV. The specs say it can handle 4K @ 60Hz. See pg. 54 here --> http://cdn.vizio.com/documents/e48ud0/um-e48ud0.pdf http://cdn.vizio.com/documents/e48ud0/um-e48ud0.pdf.

I am running a Dell Latitude E7250 with an i5-5300U cpu and Intel® HD Graphics 5500. The specs from intel say this can support 4K @ 60Hz. http://ark.intel.com/products/85213/Intel-Core-i5-5300U-Processor-3M-Cache-up-to-2_90-GHz http://ark.intel.com/products/85213/Intel-Core-i5-5300U-Processor-3M-Cache-up-to-2_90-GHz

My laptop is docked and connected via DP (I believe it is 1.2) to a DP --> HDMI 2.0 active adapter. http://www.vantecusa.com/en/product/view_detail/716 http://www.vantecusa.com/en/product/view_detail/716

However, in the intel graphics control panel, I do not get an option to select 60Hz when I choose 4K resolution. I get 30Hz, no problem but there is no 60Hz choice.

My question is, where do I look for help. Is this an intel problem, a Dell problem, or a TV problem? I have tried everything I can think of.

Hello Rgaret,

Thank you for joining the Intel communities. You can get 4k at 60Hz with DP but you will need to use straight connection in order to do that, Intel do not recommend any adapters. For better performance straight connection is the best option. If your TV does not have display port, you can try installing the INF file for your TV, you will need to download it from your TV manufacturer website. You can also try uninstalling the old driver and install the generic driver from the Intel website, you can download it here:https://downloadcenter.intel.com/download/26228/Intel-Graphics-Driver-for-Windows-10-and-Windows-7-8-1-15-40-?product=86210 https://downloadcenter.intel.com/download/26228/Intel-Graphics-Driver-for-Windows-10-and-Windows-7-8-1-15-40-?product=86210 Best regards, Ivan

Hi,

I'm just following on this thread to ask you if your issue was resolved or if you need further assistance.Thanks,Ivan

Not yet. I can't get an INF file from the TV manufacturer because they don't have one. I tried to make a custom one using the instructions from Microsoft but that's not working either. Lastly, I have to run an DP to HDMI adapter because the TV doesn't have a displayport of its own. So, for now I am living with the issue because I think it may be a deficiency in the laptop graphics card.

With an active adapter from DP to HDMI you might be able to get better resolution, also I suggest you to contact your laptop manufacturer for them to give better specifications about the laptop as they are more familiar with your component and the parts interact with each other.
