Hello. When I connect the Type-C cable monitor to a Gti14 mini computer with Thunderbolt 4, the monitor does not show the image (power is supplied to it, but no image is received). If I still connect Type-C Power to second port and I reconnect the connector usb type-c to Thunderbolt 4, then it begins to show the image. Why? If I use the same monitor with another mini pc on Chatreey T9 (Intel N100 CPU), it works with one usb type-c cable. It seems to me there is a problem with Thunderbolt 4 in this GTi14 Ultra. I updated the BIOS from T102 to T105 but it did not solve the problem!

vitasonline Hi there, Does it work if you turn on the PC first and then connect to the Type-C cable monitor ?

support1 No, it doesn’t work that way either, power will be supplied to the screen, but the image signal will not go through. It only works if external power is supplied to the screen and only then connect the tunderbolt cable. Please check it out on your monitor and send me the video.

Hi there, The monitor that requires external power before connecting the Thunderbolt cable might have higher power consumption. The power delivered through the Thunderbolt 4 port on the Gti14 mini computer alone might not be sufficient to power up the monitor and transfer the video signal simultaneously. When you connect an external power source to the monitor first, it ensures that the monitor has enough power to operate properly and then the Thunderbolt cable can handle the data transfer for the image display. When I tried our TYPE C monitor, it works without extra power, it has lower power requirement and can operate within the power limits provided by the Thunderbolt 4 port without the need for an additional power source.

support1 Hello, I checked the power consumption of my monitor and one maximum is 4W, and its specifications indicate that it does not need external power. And this monitor works great with a mini PC chatreey T9 over one type-c cable. Thunderbolt should give out up to 15W of power. Write the monitor model that you tested, or better yet, make a video.

vitasonline Hi there, The TYPE C monitor is INNOCN 13A1F Here is the video https://mega.nz/file/jixxXLZB#BcSzH8CKAKOq2Y4OoK-sb8jJl7Qjfz3gtjS1MnYtjzA

support1 Thank you! I’ll check on another monitor. My video review on Youtube channel -

support1 Hello! I tested both my mini computers via usb type-c tester POWER-Z KM003C о from ChargerLAB. When I connect the monitor to the PC chatrey t9, both power and image are transmitted via one cable, the tester detects the Svid protocol and the image immediately appears on the monitor after pressing the power button on the PC: But when I connect the monitor to the PC Gti14 ultra, only power is transmitted through one cable, the tester does not detect the Svid protocol and there is no image on the monitor after pressing the power button on the PC. If I connect the second type-c cable to power the monitor, the PD protocol changes from 15W to 5W and there is no image. When I reconnect the cable, the image starts to show. You can test POWER-Z KM003C with your INNOCN 13A1F monitor ?

vitasonline ① Reason for no image with single cable connection: Incompatible cable: The cable you are using might not be fully compatible with the power and data transmission requirements for both the PC and the monitor.Ensure that you are using a cable that is specifically designed for connecting your PC and monitor ②Reasons for PD protocol change and no image with second cable connection: Power management issue: The PC might be detecting the second cable connection as a different power source and adjusting the power delivery (PD) protocol in a way that causes issues with the monitor’s operation. Conflict between cables: The simultaneous use of two cables might be causing some kind of conflict or interference that is preventing proper image display. ③Update drivers: Update the graphics card drivers on your PC to the latest version to ensure proper compatibility with your monitor. ④Test different ports and cables: Try connecting the monitor to different ports on the PC and using different cables to see if the problem persists. This can help identify if the issue is with a specific port or cable. ⑤ Sorry, I am not in the office until Oct.8th, so I am unable to test the power-z

support1 Intel N100 cpu TDP 6w
Power adapter 35w

Hi there,
If your type c cable is not a all-in-one cable, then it cannot support video output, maybe it can only support video output,but not power supply. So when you connect another cable to charge it, it can output the video .

vitasonline

support1 I use the same cables with T9 and GTi14 !
But in T9 it works power delivery + display port at the same time, and in GTi14 only power delivery works

vitasonline Hi there,

It might the cable incompatibility issue.
When we use an all- in-one cable , it works with power delivery + display at the same time.

Hi Can you recommend a cable that is compatible?

vitasonline

I tried different cables and bought UGOURD Thunderbolt 4 Black 40G 240W 8K which has a PD chip and is defined in the E-marker cable as 0×315C vendor. But no cable displays an image.😂

support1

vitasonline That is weird.
Could you please try another one , like https://amzn.asia/d/gOfPu20

I have bought this but is doesnt work to my usb c portable monitor and external gpu

support1

narumivtl what is the brand of your monitor ?

vitasonline

I updated thunderbolt chip firmware on my GTi14 155H with T105-BIOS firmware and finally now my monitor Arzopa Z1RC works through one type-c cable!!!

vitasonline Glad to hear that 🍻
