[NAME]  Ok, we probably need to clarify a couple of things. First, I don’t see an Inspiron “7890” on Dell’s website. If that model number was accurate, it would have an 18” built-in display, and I don’t think Dell has any current laptops with 18” displays. So please recheck that model so that it’s clear what system we’re talking about. Or perhaps even better, please check the power adapter that came with your system and reply with its wattage output, which will probably be something like 130W or 180W. Although if it’s one of those numbers, you probably won’t find any display that will provide that much power over USB-C, and in fact your system might not even support being charged over USB-C at all. I’ve seen several Inspiron systems that are designed for 130W power sources but don’t support being charged over USB-C. That 130W number itself is above the 100W max of the USB PD spec that existed when current systems were designed. Dell did something proprietary on SOME of their systems and docking stations to stretch that out to run 130W over USB-C, but you won’t find that implemented on third-party products, and I haven’t seen any Dell displays support providing 130W. And even if they did, again I don’t think your system will support receiving it. I’ve only seen 130W over USB-C supported on Precision and XPS models.
Hi there, I have Inspiron 7890 with external GPU NVIDIA GeForce GTX 1650 and Thunderbolt 3 support. Which 32" monitor should I buy to be also able to play games in 4K 60Hz resolution with external GPU and charge the laptop at the same time? Is it feasible using Thunderbolt 3 or even USB-C hub monitor e.g. EW3280U  (USB-C One-Cable Connectivity) or PD3220U (Thunderbolt 3 connectivity) etc. Dell 32 4K USB-C Hub Monitor - P3222QE or Dell UltraSharp 32 4K USB-C Monitor: U3219Q. However I need one monitor for home use, entertainment and want to have very good monitor, don't need professional colors though. I have read a lot, but I don't know what will work. Thanks for reply.
Which 4K monitor is capable to use Inspiron 7890 external GPU GTX 1650 and 
charge laptop?
