Belkin Thunderbolt 3 Dock Plus

Up front, Belkin was kind enough to just accept my original and send me a replacement of the same model within a very reasonable timeframe, so good on them. However, the real problem is the display port. The exact same port others have talked about (right one if looking from the front, left from the back). Not only does the port just not work at all, it causes my mouse point to sttuter whenever something is plugged in to it. That's on a 2019 MacBook Pro, 15". It's not the ports on my mac, those work fine if I have an HDMI to USB-C/Thunderbolt 3 adapter on either side (HDMI bus and display link emulation problems), no issues at all. Funny enough, the Thunderbolt port that I could plugin my simple HDMI to Thunderbolt 3 adapter doesn't work when plugged in, even though the HDMI bus isn't in use yet. I'm using two HDMI to display link cables. To test I did the following: Plugged in both monitors using the same display link cables, one works one doesn't, the one plugged in to the problem port Swapped the inputs, same issue Swapped the entire cable, same issue Unplugged one and tried one monitor with both cables on the working port, this works fine. Unplugged that monitor and cable from the working port and plugged in to the non working. Issue returns. Went through all possible combinations of cables and monitors, as well as ports on the 15" of which there are 4, and I ran in to the issue. That's a lot of cases. So, that said, this display link issue has not been fixed, and is a total deal breaker when one of the major selling points of this hub is dual 4k support, and just general dual display link support in general. Even with a single monitor, the issue happens. Belkin, so many people are talking about this issue, why hasn't it been resolved? There are enough 5 star reviews that I had faith in the product, as a lot of times 1 star reviews can be worded poorly and not go in to enough detail, so it just ends up sounding like disgruntled customers. I can say I totally agree with them. Again, this product NEEDS to be fixed before I'll consider it again, however I doubt that'll be true as I don't really have time to wait. I recommend this as a do not buy. Belkin, thank for you for support, however this is a dealbreaker for me.
