I’ve just gotten a new Dell UP3216Q (AU$2000) to replace my AOC I2757FH (AUD$390 2 years old) but after plugging it into my Asus laptop’s (Intel HD Graphics 4000) HDMI port and firing it up I noticed that whites aren’t really white but more an off-white with a slight hint of red and yellow.

I plugged my AOC monitor back in to compare and yes to my eyes the AOC displays perfect whites. Also all other colours seem to be over saturated on the Dell, Reds, blues, greens all look really bright.

I loaded up bbc.com to compare and it just doesn’t look right on the Dell the News header looks really red when on all other devices I’ve used it looks more of a brownish red. I’ve fiddled around with menu settings on the monitor to no avail.

My question, is it just that my eyes have gotten used to my AOC or is this new Dell screen just not factory calibrated correctly. Should I send it back?

Also ever since I plugged the Dell into the HDMI port on the laptop the AOC screen now isn’t showing light greys correctly (slight green tint). The VGA port works fine (but i obviously don't want to use this) and a USB>HDMI adapter works fine too. How do I get it back to what it was? I haven’t touched Windows “Color Management” or my screens settings. Has it loaded a different color profile just for the HDMI?

Dell on the left, AOC on the right.

bbc.com Reds not right.

    Color temperature? Can't really call either of them defective. Can achieve both by changing color temperature setting of my monitor. – Tom Yan Mar 18 '16 at 6:33

    What are the available color temperatures on each of them? – Tom Yan Mar 18 '16 at 6:47

    Plugging the new machine into the old machine's display has (seemingly) permanently altered the old machine's display? – Raystafarian Mar 18 '16 at 6:50

    Is the dell factory caliberated? – Journeyman Geek Mar 18 '16 at 7:02

I'd use the dell as a baseline, personally. The yellowish tint is based off a different/'more correct' calibration. most consumer monitors are set somewhat too blue out of the box - The colour technology matters too you'll never get a TN and IPS screen identical.

I had a similar switch from a crappy asus to a P2715Q (and a second UHD monitor). Took me a week or so before my eyes got used to the Dell.

That said, when you have mismatched screens, colours are relative - it might be your eyes. Windows 8 onwards has a nice manual caliberation tool. In my case I used my dell as a baseline, then adjusted my second monitor (a cheap korean UHD thing) to get as close to it as possible. Its not identical but better than nothing.

    Yes, many cheaper LCDs are too blue nowadays, seems to be the case of the older AOC. – Vojtěch Dohnal Mar 18 '16 at 7:28
  • @VojtěchDohnal So then if the general masses have screens that are too blue shouldn't I need one too as I am designing for them. I've looked at all the monitors, laptops, Macbooks, iPads, tablets and phones (mostly top of the range equipment) around the office and at home and none of them show the big difference like the Dell. For instance the blue (#1485EE) in our company logo, on the Dell it's quite a garish blue and nothing like what everything else shows even in print. To match the blue colour(by sight) on the Dell I had to darken it a few shades to #107DE0. – JT... Mar 21 '16 at 3:03
  • My concern is that I would have to over/under compensate on everything I design (mostly web UI). The odd thing is I've been doing this job for 15 years and never seen this much of a difference when upgrading screens which I do every few years. Yes my last screen AOC wasn't the most expensive screen but I never saw any big difference between that and the previous Samsung SyncMaster which wasn't a cheap monitor about 5years ago. – JT...

  • Anyway thanks everyone for your time and comments. I shall give it a couple more days to see if my eyes adjust :) – JT... Mar 21 '16 at 3:23

    Yeah, I think the windows calibration tool might be your best bet. Give it a shot, and you can always switch back to the manufacturer calibration. I have my p2715Q on the defaults (custom colour - with RGB all on full) and the colour profile for my monitor - you can find this under colour management – Journeyman Geek Mar 21 '16 at 3:50
