I recently purchased a Lenovo X1 Carbon off Ebay for a rather good price. Upon arriving, I started to notice something odd about the screen.
For certain Red on Red gradients, and Red on Grey or Black, strange flickering black or pure red 255,0,0 flickering pixels appear.
In addition to this, certain text and other things create an odd penumbra-like 'drop shadow' that is lighter than the surrounding background.
The odd thing about this, is that if I go into the graphics properties, and change the brightness and contrast VERY slightly, the drop shadow issue disappears completely, and the weird flickering pixel issue improves somewhat, and 'shifts' to a different shade of red.
The seller has made me two offers, 1), a full refund, and 2). a partial refund to pay for me to buy a replacement LCD panel.
I'm okay with replacing the LCD panel myself, and had I not gotten the laptop at such a good price, I'd probably just send it back for a full refund however, the seller does not have any more of the specific model that I want (i7, 8gb ram, 180gb ssd), and everything else about the laptop I am giddily happy with. So I'd like to fix it if at all possible.
A few notes: The pixel issue is visible even in the system bios around the red dot atop the "i" in "Thinkpad", so it can't be a driver thing. This issue is one I've not encountered before, so I'm not 100% sure that it's the LCD panel, and not a more sinister issue, like the GPU. The issue reminds me vaguely of older LCD panels connected to PCs via analog VGA cables, with the sync and or pixel clock set incorrectly. Could that apply here?
Is this most likely to be an issue with the LCD panel itself? Or something else? Is it work taking the risk to get a partial refund and buy a replacement LCD panel?
Here are some pictures of the individual issues: https://www.dropbox.com/s/cgbxz5k2z9nd9rg/x1carbon.png
