Over these few weeks, thanks to my Lenovo Yoga died on me (mentioned here), I have to buy a new set of external adaptors. Since the Lenovo Yoga has two USB-C ports but no regular USB port, I have to purchase external adaptor that is built for USB-C. It has its advantage for sure since I just need to use one single port for connection to my 4K HD monitor with ports for networking and other USB devices all in one compact device.
Now that I am using Microsoft Surface Pro 6, all these gadgets no longer work. Trust me. I tried. I even found a USB-C convertor to plug into the Surface USB 3.0 port and no luck. The USB ports on the adaptor kind of work but not the networking port. Definitely no output to the monitor either.
So I have to give them all up and buy myself a new all-in-one adaptor which I found on Amazon.
It works … except that the HDMI port does not produce the 4K resolution on my 4K HD monitor. I tried everything including direct changes to the resolution settings. It just cannot get my 4K monitor to display 4K.
So, I tried this on my 4K TV. And it worked. Damn, that’s annoying.
So I ordered a simple display port to HDMI adaptor hoping that it may solve the problem this time.
And nope. It has exactly the same problem. They just cannot sync with my 4K monitor.
Some people asking exactly the same question why the adaptors are not working. The vendors and some other “smart” users blame the problem on the HDMI cable saying that a low quality one will not work. Well, I am using exactly the same cable that used to connect my Lenovo Yoga to the same monitor. I also use this same cable for the connection to TV which works. Don’t tell me it is its low quality causing the problem.
The search goes on. I eventually bought this adaptor.
And it works! I finally found one that works with my 4K monitor giving me 4K resolution.
I don’t blame the other 2 adaptors for not being able to output 4K resolution on my monitor. After all they both can produce 4K output on my TV. My guess is that the 4K specification can be very tricky so a better adaptor may be able to handle more types of monitors.
