Typically you have to dig through the menu settings on the monitor. Somewhere there’s going to be a set of buttons that let you adjust mode, color, contrast, brightness, etc. Somewhere within that maze of menus you would find the DisplayPort version.

Amazon is a real crapshoot anymore. Lots of deceitful ratings and bait and switch products. It may say certified, but by whom? Intel is the only body that legitimately certifies Thunderbolt. They’ve done a pretty good job at maintaining a list of products and manufacturers - if this company isn’t listed, this adapter might not actually be certified.

I have one for each monitor - I stopped using the Old Dongle to see if connecting each monitor via its own adaptor (i.e. using 3 of the 4 thunderports on the MBP) was more stable.
USB 3.1 gen 1 stuff is really hard to find quality products. I’ve had good luck with a couple different brands (Monoprice and CJ5 from Staples), but have had issues with several different ones from Amazon which I sent back. If you have this setup now is it more stable than the adapter above?

It’s certainly possible, I’m not sure. I have all Dell displays at work and still have this issue. If it’s of any consequence I’ve had less issues with cables (usb type-c male to DisplayPort/HDMI male) than using a dongle (male usb 3.1 or TB3 to female DisplayPort/HDMI) then using a male to male DisplayPort/HDMI cable.
The best way is to try without that display for a couple of days to see if your problems go away.
Just to confirm, I’m assuming the problems you’re having are with the displays flashing on/off or intermittently going blank for a few a seconds then coming back on? If they just aren’t coming on at all, that might be a different issue.
FWIW I just remembered that I tried my “dependable HDMI dongle” with a TCL TV and all it would do is flash a blue screen every 5 or so second. I swapped it for a Pluggable USB-C to HDMI cable and it worked perfectly.
It’s unfortunate that all the alt mode video is such a hassle. Worse is that the alt mode is a feature of USB and that governing body is in a poor state of affairs which doesn’t look to be getting better soon (see USB 3.1 gen 2 to add to confusion). I’m sure there are a high percentage of products using the logos incorrectly and don’t meet certification requirements. This brand new LG display I have touts a USB 3 type a hub, however it clearly identifies to the Mac as a USB 2 hub. Upon some research - the USB chipset used in the display is USB 3 capable - but it’s likely it got wired into a USB 2 configuration for the type A ports (and the used blue ports which mean 3.0) while the single type c port is 3.0, but used for DisplayPort - sigh...
So a couple quick questions - (please keep in mind I am fairly amateur from a knowledgeable standpoint on some of this stuff):
How would I go about setting my Samsungs to the latest DisplayPort version?

I bought a dongle already, but I am willing to try a new one.
