I have upgraded to LG 27UL850-WB.AUS. I have a NUC8i7HVK1 with HD Graphics 630 and Radeon RX VEG M GH Graphics Hardware. There is a vertical line in the center of the display and offsets at the split. This happens after booting the NUC from cold.

The display is also in standby. If I switch the input between 1 and 2. Then go back to original input for the NUC, issue goes away. This is happening at any resolution. If I connect a different PC to same input I'm unable to duplicate the symptom. If I use the USBC port on NUC to the USBC on Display this is not an issue. This is happening on all HDMI ports on the NUC. I have used multiple HDMI cables.

Can you post a picture of this phenomena? Use the paperclip icon to upload and attach your picture.

If would also be a good idea for you to download and run the Intel System Support Utility for Windows and then attach the log file produced by this utility to your response.

Scott, Thanks for the quick response. I've attached two pictures. Sorry for the quality. A screen grab does not capture this issue. Very odd. Log is attached as well.

I can see that you are on the latest bios. I also see that you are using 7158 for the Intel graphics.

Can you try using 6912 just to test and see if the condition still exists?

P.S. Scott is now on travel.

[JHall8]

Went to 6912. Same issue. See attached screen grab

I wish had more to offer. Perhaps one of the Intel support engineers can assist.

Hello JHall8,

To better assist you with this issue, could you please provide us or help us to confirm the following?

-What happens if you set the resolution and refresh rate to 1920*1080 at 60Hz?

-Which was the order you install the graphics drivers (Intel® and then Radeon™ or vice-versa)?

-You mentioned that you have tried different HDMI® cables, did you use HDMI® 2.0 cables?

-Does the issue got replicated using 30Hz of refresh rate instead of 60Hz?

-What happens if you set the resolution and refresh rate to 1920*1080 at 60Hz?

-Does the issue got replicated using 30Hz of refresh rate instead of 60Hz?

I do not see the issue in 1920 x 1080 60 or 30 Hz. By the way I only see the Radeon RX Vega utility to perform this operation.

-Which was the order you install the graphics drivers (Intel® and then Radeon™ or vice-versa)?

I'll be honest, I'm not sure. I purchased NUC8i7HVK1 July 13th 2018. Installed all the drivers and have been using your "Intel Support Assist"web updater tool to monitor and update all current drivers.

I'm noticing that I no longer see Intel Graphics Setting utility running in task bar under Window 10. There was a new Intel Graphics utility that showed up however since I removed and been reinstalling both the Radeon and Intel graphic drivers, I no longer see this intel utility.

I original had the NUC connected to a conventional Samsung 1080P TV using HDMI with no issues.

-You mentioned that you have tried different HDMI® cables, did you use HDMI® 2.0 cables?

I'm using both the High Speed Cables HDMI that came with the LG 27UL850-WB.AUS. I also had existing HDMI 2.0 cable thinking it may be an HDMI cable issue. Neither cable resolved the issue.

Hello JHall8,

Could you please tell me if you have tried different displays and if the issue got replicated with other displays? or tried to connect this display to another computer? Does the issue got replicated on other computers?

As I had shared a number of weeks ago, I’ve connected my Lenovo Tablet to the new display and did not have the issue. I originally was using a standard Samsung TV with 1080P resolution connected to the NUC. I never saw this issue. So it’s a relationship between the NUC and the new LG Display.

Hello JHall8,

I support NUC and I have been looking into this issue, I am aware of compatibility issues with some LG* Displays in the past but nothing like this and based on the issue description I agree that this looks like something not working on the relationship between the NUC (HDMI) and the LG Display. I am saying HDMI because I don't know if other graphics interface exhibits the same behavior, for example if you use a USB type C to HDMI adapter.

I also brought up this issue to the product support team and we agreed that this may be a compatibility issue that we are not going to be able to fix in the short term, if you cannot use or test any other graphics interface such as USB Type-C or DP and strictly need to use this Monitor in combination with the NUC8i7HVK, I would recommend that you reach out to our Customer Support Service either by phone or chat in order to explore other possible options to resolve this issue.

Here is the contact us information: https://www.intel.com/content/www/us/en/support/contact-support.html#@6 please refer to case # 4353355.

Regards,

Ronnie, The display does support USB-TYPE C. So I’ve been supporting the NUC USB-type-C output to the LG Display input and it works great. I know that many customers move on after the have a work around. It’s unfortunate because manufactures are not receiving proper feedback so that issues like this can get the proper attention they deserve. I wanted to make you aware of this issue so that others will not make a similar discovery. This is a very popular display.

[Ronny_G_Intel]

Hi JHall8,

I agree with you and believe me, I would really like to have a different approach for compatibility issues but it is very difficult to test or validate all possible devices that are out there on the market.

I am keeping this monitor (LG 27UL850-WB) on my radar in case we have the opportunity to test but for now I cant make any promise.

I apologize for the inconvenience.

Regards,

Ronny G
