That’s really unfortunate.
Did you account for the increased brightness of the new panel? The new panel is 498.5 nit vs 436 according to
At 50℅ brightness on the old display, the new one should be set at 43.76% to match, or 87.5% for 100%.
It’s a good point. The new screen is a little brighter. I didn’t adjust the brightness. The difference is small though. I’m not sure the brightness slider has that much fidelity to be able to make them completely even.
I suspect pushing an extra 2 million pixels has more to do with the extra power draw than the extra brightness.
Anyone who is concerned about the rounded corners, I was also concerned about this. It seemed strange to me, but I really wanted a better display so I ordered one. I was afraid it would seem distracting or at least be an OCD issue. I was pleasantly surprised just how small the round over is. I think most people wouldn’t even notice unless it was pointed out to them. On the other hand I just got a Pixel 9 Pro XL and the corners are so rounded it’s ridiculous! The most rounded over corners I have ever seen on anything. The Framework display is just a few missing pixels in the very corner in comparison.

For those who can’t get enough tests, I ran a few tests to see how much of a difference the brightness setting makes.
Test Setup
- AMD 7840 CPU
- 32 GB DDR5-5600 RAM
- 2880x1920 120Hz Screen
- 200% Screen resolution scaling
- 61Wh Battery
- Fedora 40
- Firefox 129.x web browser
- Sound muted
- YouTube 1080p full screen video “Baelin’s Route - An Epic NPC Man Adventure”
I ran the video twice (about 75 minutes) for each test. I set the brightness before each test. In Fedora, there are 21 values between the dimmest setting and the brightest setting. This made it easy to split the brightness levels:
- 0 (dimmest)
- 7 (33%)
- 14 (66%)
- 21 (brightest)
Note: The brightness level I used for all the other tests in this thread was 33% (I described it as 30% in other posts).
I polled the battery every minute.
Here are the results:
| Brightness Level | Average System Power Usage | Battery Life Loss |
|---|---|---|
| Dimmest (0) | 7.79 W | 0 hours |
| 33% (7) | 9.35 W | 1.31 hours |
| 66% (14) | 10.25 W | 1.88 hours |
| Brightest (21) | 10.44 W | 1.99 hours |
There’s about a 2 hour battery life difference between the dimmest and brightest settings. It also appears that the brightness levels are not linear.

i’ve actually noticed WORSE ghosting with the 2.8k display. has anyone else noticed this? currently trying about a replacement for my first 2.8k display due to it.

Wow, this is just fantasy material to me.
On Linux + the “super cool/efficient” AMD 7840U chip, NO WAY I would have 74% juice left after a 4h Netflix stream, LOL
I’d be happy if I’m still above 50% by then.
TBH it’s my first AMD purchase ever, and probably also the last.
And I can’t blame Linux too much, cause my previous DELL with an i7 11th gen had wonderful battery life (on Linux).
Have you enabled vaapi and set power profile to power-saver ? and your linux’s up to date ?
here 7840U is very efficient
Yes, I’ve noticed the ghosting also. If I’m scrolling down a dark webpage with white text it is extremely noticeable. Changing between 60Hz and 120Hz has no effect.
But worse is the terrible color cast on my new 2.8K screen. Mine shifts heavily into the green. I thought I had a bad screen, but I’ve heard other people who’ve upgraded to this screen say theirs is the same. I was able to correct it by calibrating the screen with a Datacolor Spyder. But, I get the feeling these screens are slightly inferior panels.
