I have an Intel UHD 620 Graphics Card on a lenovo flex 5-15 attached to an LG lg 32uk50t-W (new version of 32ud59-b monitor) 4k monitor capable of 4k @ 60hz and I can only get it to display 4k @ 30 hz. How can I fix this?

I have tried man solutions: Install LG Driver, Upgrade Intel UHD 620 Driver, Enable HDMI Ultra Deep Color.

Hello MTom0 Thank you for posting in the Intel Community. Bear in mind that this behavior can be because of a limitation on the graphics bandwidth for the video port on the system. What is the model of the Intel® processor? What video output are you using to connect the external display? Have you confirm with Lenovo if the 4K @60Hz resolution is supported for the external display? Hope this helps. Regards, Leonardo C.

Hello MTom0 Thank you for the information. The Intel® Core™ i7-8550U Processor (https://ark.intel.com/content/www/us/en/ark/products/122589/intel-core-i7-8550u-processor-8m-cache-u...) supports the following resolution 4096x2304@24Hz on Max Resolution (HDMI 1.4), I recommend confining with Lenovo what is the laptop's port capabilities for resolution, bear in mind that the internal design of the motherboard might include video converters from HDMI® to DP. In addition you can review/confirm that the video cable revision supports the video bandwidth for 4K @60Hz. Lenovo support: https://support.lenovo.com/us/en/ Hope this helps. Regards, Leonardo C.
