Discussion on this is muddy, but the issue seems to somehow be related to the fact that the integrated graphics uses system RAM for graphics, whereas dedicated graphics cards have their own VRAM (as much as 2G of it, and perhaps more).
The tooltips issue is just a tip of the iceberg symptom. Lightroom does work and works fine as near as I can tell. Photoshop also works, and only the tooltips have failed to work so far. But I shelled out $130 for an MSI "GeForce GT 1030 card with 2G of video ram. I insist on having a video card with no fan for both reliability and low noise.Just for the record, my monitor is a Dell model U2413. It runs at 1920 by 1200 resolution.
Reading some online resources, they indicate that I should uninstall any video drivers before installing the new card, so back we go to the old setup for that. Being lazy, I first try just moving the HDMI cable back to the motherboard connector, but that does not work at all, we get a black screen all day long. So the new video card needs to come back out. Now we get the blue windows symbol in the middle and the spinning progress thing. Of course there was no way to do a clean shutdown, so it may have a bit of a mess to tidy up. It manages to bring the system up and is asking for my password.
My system (nearly 8 years old, but doing just fine thanks) has an Intel i7-3770K processor. This chip includes the GMA-HD 4000 graphics that has been running this system for most of those 8 years. Quite possibly I have Intel graphics drivers to get rid of. I got to Settings, Apps, and find "Intel HD Graphics driver" and click the Uninstall button. I promise to restart the system and shut it down. Back in goes the 1030 card, I move the HDMI cable, and power back up. We get the windows symbol and spinning progress gadget again. And voila! Windows 10 comes back up on the new graphics card.
I am up on some seriously degraded resolution and the system is very sluggish. And it won't offer me a login prompt (I do get the gadget that offers me a shutdown or restart menu). I select restart based on one tip. I get a blue screen saying "please wait" along with a spinning gizmo that is busy a lot longer than last time. The trick was patience. After about 20 minutes, I get offered a normal windows session albeit at wretched resolution.
Now we want to get the Nvidia drivers for this card. I launch Chrome. I search for Nvidia 1030 drivers, get the product page. I select "Drivers" and get a form to fill out. I enter Geforce, 10 series, 1030, and it figures out I have Windows 10, 64 bit. That is the "manual search" mode and is apparently buggy, so I download the "GeForce Experience" thing instead. I close Chrome and run the EXE it downloads. After I agree to terms, it installs 3.23.0.74 of the Experience app. Finishing the install seems to be taking forever. Now it wants me to create an account, this is turning into a real pain in the ass. The second try worked, with the usual email verification.
Now it is busy loading a "Game Ready" driver (831 Mb) version 496.49. After it downloads, I select "Express Installation" and give my admin password. Now it is creeping along installing the driver. In the midst of it my graphics resolution changes to something nice! Incredibly, it did not want to reboot my machine.
I launch Photoshop and now I do get the animated tooltips, so apparently this was a success, but it was a 2-3 hour struggle on a Sunday afternoon.
Checking the resolution setting is easy enough. I right click on a blank area of the screen and select "display settings" in the menu that appears.
