today my new T480 arrived. And as I started it and set up the brightness to maximum I was a little bit disappointened. It is too dark?
My model is the 20L5000GE with WQHD display. (300 ntis??)
I don't know if this is normal or what can I do? Do I have to use the drivers from the lenovo Hompage (I alrady did updated with windows 10 normal update)
Should I return it?
I really love this laptop.
It is so sad that such a perfect laptop or Lenovo in general does not have good display with high brightness?
Solved! Go to Solution.

"Too dark" is subjective. I cannot comment without seeing the screen. When I have an issue like yours, I prefer to physically take the machine a warranty servicer or dealer. I can then turn the machine on and we can discuss it while we are both present. If you return it, you don't have a good way to know if your screen is normal or defective.

I don't feel that this are the promised 300 ntis? I use an very old acer laptop with a relatively dimm display and if I compare this to the new thinkpad, the thinkpad is dimmer? Could this be a driver issue? Can you tell me what I can test or change before goiing to support?
How can I make you see the screen? ;-)
I read many test and I read everytime 300 ntis are a very high brighntess. But now as I see it, it doesn't feel very bright?

It could be the driver. If you run the program "moninfo" (freeware), you can determine if you have the correct panel. It should tell you the model name in the panel's configuration chip.

I was looking for the model of the panel. On the Acer, it is B133XTN01.3, but I cannot find a datasheet so I don't have more information on that one. As far as the driver, I would install Lenovo Vantage (Microsoft store) and use that tool to install the latest drivers.

So, what do you suggest? Should I return? Give it to diagnostics?
Is a WQHD actaully dimmer? Becauce my acer should have 220 ntis and as I said if I put the lenovo beside it, the WQHD display appears darker

My suggestion is in my ffirst response:
"I prefer to physically take the machine a warranty servicer or dealer. I can then turn the machine on and we can discuss it while we are both present. If you return it, you don't have a good way to know if your screen is normal or defective."

Hi, I've got the T480 with the FHD IPS screen, so only 250nits and I had the same issue as you had.. Screen brigthess turned to max was too dark to use if I had the window blinds open.
What fixed it for me: I went to Device Manager, expanded the Monitors section, right clicked my current monitor (which for me is Wide viewing angle & High density FlexView Display 1920x1080) and selected Update Driver and then clicked Search Automatically...
Windows found a new driver and updated it.
This drastically increased the brightness to the point that now I can even use the laptop outside.
Hope this helps

One other thing to check: there's an automatic brightness option. Used to be in Vantage, now seems to be in Windows Settings. Turning it on leaves brightness still user-adjustable but on my laptops it severely reduces the max brightness - at least in my light environment.
