Dell cannot issue an exchange without proof of the fault. You are in rights to simply return it for refund. You have to do this inside of the initial 30 days from the invoice date.
What is the 20 digit serial number and A0x revision? Run the P2417H Built-in Diagnostics (page 55) and then take pictures of the screen showing us the issue. Post the pictures on this thread.
Thanks for the answer, I'll run the test when I get home on weekend. However, it may be tricky to actually take a picture, I already tried to with my phone's camera (8 MP) but the dots are too small and faint to be visible or cannot be distinguished from the dust . I'll try to use a better camera this time.
I've run the built-in diagnostics, all pixels are perfect. Actually, I already checked this last week with a self-made HTML page, I even simulated bright pixels to compare them with the dots -- that's how I determined those dots are way smaller, something like 1/10 of a subpixel.
Unfortunately, I cannot shot sharp enough photo with my 14 MP camera, the dots are not visible on any of them.
