Latitue 5400, 16GB RAM, i7-8665U (8th Gen). Connected to a Dell WD19 Thunderbolt hub via the only USB-C connector on the laptop, utilizing the i7 integrated graphics. I realize it is only 3-display capable.
Three external monitors, all 1080p. Two using DP and one HDMI. The laptop will output to two @ 1080p plus its built-in monitor @ 1080p. If you try the three externals, it will lower the resolution to one. If you try some trickery in Intel Graphics Command Center, I have got all three to 1080p once, but the video quality was awful on one of the monitors.
It is not anything external of the laptop. Taking the same USB-C (Thunderbolt) connection and plugging it into my Surface Pro 7 (10th Gen i5), all three externals work perfectly. I've also tried it with all three monitor connections directly to the WD19 and running all three to a single DP port via a DP 1.4 MTB hub (which is my main use case, as I move the single display port connector over to my iRacing desktop with a GTX 1060 that has no issues pushing triple 1080p through it).
I'm running out of ideas. The Dell has all Windows 10 updates and the latest drivers. I just can't figure out why it can't push triple 1080p externally but yet can process two external and one internal just fine.
