Club 3DCSV-7200 Multistream Transport Hub DisplayPort 1.4 to HDMI Dual Monitor 4K60Hz M/F Adapters, Black

This product is patheticly designed, it worked for me fine for about 3 months then it would suddenly lose connection to one of the monitors for 1-3 seconds, and then come back. Their support keeps proclaiming that it is either Dell's drivers for video, or my PC cannot handle it. I have proof that their adapter is what causes my displays to drop, the one connection directly to my PC is fine without any drop outs. Don't buy this if intended for more than a few months expecting problems ahead

Does not extend my display. Only duplicates.Does not show additional monitor in display settings.

ある頻度で画面がちらつき、机の前でライターをつけると映像出力されなくなるという謎の現象がおこっていましたが、ケーブルがノイズを拾って不安定になっているのかな？と思い、USBケーブルを他社製（〇GREEN製）のものに変えたところ挙動が安定しました。とりあえずしばらく使います。2023/07/19追記usbバスパワーのusbハブから電源を取るとより安定しました。
