Given the refund on the Asus PB287Q the LG 27UL500-W has been acquired to attempt to have a quality 4K60 panel for the studio. LG makes IPS panels for the entire industry, OEMs may use custom logic boards. The LG panel offers DisplayPort along with HDMI. The LG 27UL500-W is new model for 2019.
The more expensive models offer a better stand. The old Asus VS228 has a basic stand that is similar to the one on the LG 27UL500-W which simply tilts as needed.
The LG 27UL500-W is a ISP panel and it offers HDR 10 so it should work better with Windows 10. The requirements of 3840×2160 60Hz with Deep Color (10-bit) is easily met with this panel.
DisplayPort is 1.4 generally needed to support the extremes of 3840×2160 with HDR10 enabled etc. HDMI 2.0b can do HDR10 as well. With either HDMI or DisplayPort the HDR mode is 59.97 Hz.
The LG 27UL500-W supports about 98% of the sRGB which makes it almost ideal for watching television shows movies and even games. The response time of 5ms is excellent so even fast action will be acceptably good. Hockey is one of the most dynamic of sports so a high 60fps framerate with a fast response rate make the LG 27UL500-W suitable for any type of programming.
The LG 27UL500-W supports HDR10 so this panel should be compatible with the Window display settings. The HDR is a feature of Windows 10 version 1803 and above.
Earlier versions of Windows do support Deep Color but the HDR is a standardized setting. Some call HDR a wide color gamut (WCG) due to the 1 billion possible colors. HDR10 uses about 25% more bandwidth compared to 8-bit color.
VESA has more focus on HDR than what Windows 10 uses with its basic display model. The focus is mostly with DisplayPort capabilities as opposed to HDMI.
Many of the DisplayPort cables I have work with 1920×1080 panels fine but at 3840×2160 is much more demanding and they do not work. All of my HDMI cables generally work so there is much more testing needed.
With HDR enabled in Windows the LG 27UL500-W makes photographs look very good. Modern mobile phones have long supported HDR so having a suitable panel allows users to see the color quality natively.
Early on the HDR was problematic on some users machines but it was fixed quickly after a few posts on various forums and the Windows Feedback. One person said his panel showed a pinkish tint with the HDR enabled.
Windows 1809 and above seem to be problem free with HDR panels. AMD and nVidia both have suitable support for HDR10 with DisplayPort 1.4 capable cards.
By default FreeSync is not enabled. It can be activated in the panel settings. The advanced mode is the best bet with modern video cards,
The old HDMI cable that came with the Asus VS228 panel actually works at 4K60 with the LG 27UL500-W. It seems that HDMI cables have been better with high bandwidth loads which is eye opening. Tho old cable even works with HDR enabled.
The same cannot be said for several DisplayPort cables which generally work at 1920×1080 but fail at 3840×2160. The LG 27UL500-W came with a heavy DisplayPort cable that does work fine. The reason for DisplayPort is to support the richest possible image on the panel.
