Hi, I just recently got a dell 5520 lapop with integrated Intel HD 630 graphic chipset.
No matter what I try, I can't get it to display 4k@60hz!
Here is the relevant informations:
- Windows 10, 64bits, version 1709 (latest build 16299.19)
- Intel core i7-7820, 32 GB ram
- Intel graphic HD 630, 22.214.171.12464 driver (2017-04-21)
- Monitor: Asus PB287Q (See: https://www.asus.com/us/Commercial-Monitors/PB287Q/ PB287Q | Monitors | ASUS USA )
Since the laptop only has a HDMI 1.4 port, I reverted back to using a USB-C to DisplayPort external adapter
http://www.iczitech.com/product/product/index/id/150 USB Type C to DisplayPort adapter (IZEC-A46) ICZI Which support UHD@60hz on DP
When I add UHD@60 resolution to the Intel Graphic Control Panel, It says "bandwidth exceeded"
Actually the chinglish description of the adapter nowhere says 4K@60Hz- 4K video resolution requires a 4K capable computer video source, DP cable, and output display.
According to https://ark.intel.com/products/97496/Intel-Core-i7-7820HQ-Processor-8M-Cache-up-to-3_90-GHz Intel® Core™ i7-7820HQ Processor (8M Cache, up to 3.90 GHz) Product Specifications you need a straight DP connection.
4K support indicates the product's support of 4K resolution, defined here as minimum 3840 x 2160.
Product description on Amazon as well as some of the comments tells it supports 4k@60.

"Resolution up to 4k x 2k (3840 x 2160) @60Hz & @30Hz; Supports Multi-Stream (MST) for daisy chaining multiple monitors and high precision audio such as LCPM, DTS, and Digital Dolby."
"Works exactly as intended and outputs 4k @ 60hz out of my X1 Carbon 5th gen."
"It works 4k 60hz between xps 9560 and Dell S2817Q."
You need to find the bottleneck.
In best case another video, USB-C or TBT 3 driver will help.
In worst case the monitor or the computer (particularly it's BIOS) is the culprit.
