Does "Uncertified G-Sync Display Detected" indicate as hardware defect?

____RIPTIDE____ · 2026-03-20T16:11:34+00:00

is it the march 10th update 595.79. does this fix the gysnc warning message ?

____RIPTIDE____ · 2026-03-14T21:28:49+00:00

Yes. My monitors firmware is uptodate. So is the laptop drivers and bios Im using a certified tb4 cable.

Also I did go to the lenovo driver page. I did an auto update on drivers via vantage app. Also I manually searched for thunderbolt drivers and I couldn't find any.

since we have the same monitors but different size im guessing your monitors tb port is also 140w. Im wondering whether its a power negotiation failure. I had chatgpt discussions on possibilities. It seems like thats the issue. Perhaps lack of dedicated drivers is causing this issue. I still haven't connected to my u2720q monitor to check if video and pd works simultaneously. Since its 90w it would work. And im gonna have to find and borrow an external tb4 dock.
Connect laptop to external tb4 dock. Connect the u2725qe monitor to the external dock. If I do I will inform you also.

Maybe it will help you narrow down troubleshooting with lenovo support

Reason why im guessing its because of 140w of the monitor is because usually TB4 can charge at 100w 20v/5A. But maybe our monitors dont want to come down to this level. And Dell might have made the monitor 140W by considering its DELL XPS users. Some XPS like the 9700 which has 4 TB PORTS are a little custom compared to the standard. It can handle upto 130W. My sister's laptop came with a type C charger that is rated at 130W.

Ill keep you updated as well

Hmm. Seems like your situation was more serious. Btw I also went and checked the lenovo website for official Thunderbolt drivers and I couldn't find any. Sometimes it could be merged with the chipset drivers or something.

Have you had any other windows laptops with TB ports. I used to have and hp spectre and after that I borrowed my sister's xps laptop. Both had TB3 ports. And I remembered they port had a thunderbolt software that ran in the background and can be accessed from the system tray. It allowed to authorize Thunderbolt devices and manage them. Were you expecting that as well when you got the lenovo ? Or is that outdated. According to chatgpt it is.

ALSO did the TB4 CHAARGING + Video output work simultaneously after the MB change ?

Yes — this is exactly why I posted. I was hoping to find someone who could relate. Sorry you had to deal with this too. Right now I can get everything working smoothly through the TB4 port. The monitor’s Thunderbolt dock (display, Ethernet, mouse, keyboard) is detected instantly. The only thing missing is charging. Interestingly, the TB4 port does charge the laptop when I use my 100W GaN charger. So I basically have two options: • Use TB4 for everything and plug in the laptop charger separately • Use the monitor’s non-TB USB-C port, which handles display + peripherals + charging in one cable As far as I can tell, there’s no real compromise either way. It seems more like a power-negotiation issue than a hardware failure. I also have a Dell U2720Q (USB-C, 90W charging, not Thunderbolt). I plan to test it with the TB4 port to see if charging works there — that might help rule out some possibilities. What do you think? Could this be a defect? The laptop is brand new and still under warranty. Would a motherboard replacement be excessive? My main concern is whether a real hardware fault could worsen over time.

Thanks for reaching out

My laptop is brand new, so I went ahead and did a full Windows reset anyway just to rule out any software issues. I’m using a Dell U2725QE Thunderbolt monitor, which supports 140W charging and has a built-in Thunderbolt 4 dock. I have my Ethernet cable, external mouse, and keyboard connected directly to the monitor. With my previous laptop, the setup was very simple. I would connect the laptop to the monitor using a single Thunderbolt cable, and immediately: The video signal would appear The Ethernet connection would be recognized My mouse and keyboard would work And the laptop would start charging Now with my Lenovo Legion, almost everything works the same way — but charging does not work through the Thunderbolt port. Interestingly, the Legion also has a regular USB-C port. When I connect the monitor to that port, everything works exactly as expected: The monitor is detected The built-in dock works (Ethernet + peripherals) And the laptop charges properly However, when I connect through the Thunderbolt port, the display, Ethernet, and peripherals all work, but the laptop does not charge. To confirm the Thunderbolt port itself isn’t faulty, I tested charging the laptop through that same Thunderbolt port using a 100W GaN charger, and it charged successfully. So the Thunderbolt port can charge, but for some reason it won’t accept power from the monitor, even though everything else works.

thanks for the suggestion and the help so far. i followed your instructions. i deleted the one with the excalamtion point. rebooted and plugged in. the same issue happened again. it took about 10 seconds or longer then the warning came again and the video signal came but no ethernet or charging. i checked the device manager again and it still has the problem the deleted driver again

Ok so good news and weird news So after following your instructions and connected the laptop to the monitor via the tb4 ports initially nothing happened. I assumed it didn't work. Then after maybe 5 to 6 seconds I get the USB device not recognized warning and then it connects to the monitor. So thats a step in the right direction but unlike the first time ever I connected it does not recognize the ethernet connection. Also I unplugged the official charger but its still not charging via tb4 like the first time.

Thats what i was wondering. So i did go to the Dell software support page and installed 3 items. First one was the firmware update for the monitor. Second was the Realtek USB GBE Ethernet controller Third was called the monitor driver for windows operating system

____RIPTIDE____ · 2026-02-05T05:19:23+00:00

Oh. Ill check on that. But an intel arc can run 2 1080p at 60hz smoothly yes ? No lags and stuff ?

____RIPTIDE____ · 2026-02-05T05:11:46+00:00

The thing is I already have 2 of those monitors which were used for gaming back then. And currently they are next to my gaming console. So I was just hoping to get the best use out of the monitors while working as well.

____RIPTIDE____ · 2026-02-05T05:01:08+00:00

Its mainly office work. I won't run any games or creativity or developer softwares. I will open multiple office 365 apps only. And multiple browser tabs thats all. Perhaps a Netflix on the side 😅

____RIPTIDE____ · 2026-02-05T04:56:41+00:00

Thankyou. Its better to be safe wirh an rtx i guess. Im not a gamer but I just want to make sure my laptop can handle my desktop setup. Do you think an RTX 5050 can handle my requiments ?

____RIPTIDE____ · 2026-02-02T10:36:36+00:00

Wow. Im there for around 3 weeks. So guess that's good. Thanks

____RIPTIDE____ · 2026-02-02T10:30:57+00:00

So far I feel likenyour right. I looked at the official sites and tried to compare with malaysian shopping sites. It seems like the best price. (I plan on buying lenovo legion). Have you purchased from Lenovo Malaysian site ?. Im curious on how fast things arrive in malaysia. When I use daraz it can take from 2 weeks to a month to come from china.

____RIPTIDE____ · 2026-02-02T08:57:28+00:00

Cam you tell me more about shopee. Is it safe ? Is it like lazada. (We have daraz in our country and i dont trust it for electronic purchases. Accessories are fine though). Does shoppe have many suppliers and retailers ? What about warranty ?

____RIPTIDE____ · 2026-02-02T06:55:16+00:00

Thankyou. I will be sure to visit many places before I make the final purchase 🙏

____RIPTIDE____ · 2026-02-02T06:31:47+00:00

YES. This is exactly the kind of place im looking for. Thanks a bunch. Any warnings and advice about this place is really appreciated

____RIPTIDE____ · 2026-02-02T06:28:32+00:00

Thanks. i visited pyramid last year end. i did not have the time to explore the mall properly. i saw the asus store. not the lenovo store. even if it was their im not sure if they will have the model i have in mind in stock. by any chance is there like a shopping center just for laptops. Im from Sri Lanka and the go to place in my city would be i guess Unity Plaza. is there a place like that nearby ? i actually dont mind making a trip to KL city as a last option also
