Hello, I bought a LG 32MP58HQ-P IPS LED Monitor.

http://www.lg.com/ca_en/desktop-monitors/lg-32MP58HQ-P

It supports a native resolution of 1920 × 1080.

When I moved the lovely macrumors browser to that screen, the white background became yellowish. How come? I tried different picture mode, color temp and gamma. There is no improvement. Also, now I can see big ugly pixels forming each letter. Is it because of the relatively small resolution at 32" screen?

1920x1080 on a 32 inch monitor is a low resolution. We have some cheap 23 inch monitors in the office with the same resolution.

Also the yellowish display you described could be correct, and your other screen is blueish!

The only way to know for sure is to measure and set it using a calibration device like a Colormunki.
 
Not to be captain obvious but is nightshift on?

There is no inherent yellow tint to the technology but accuracy varies and calibration can matter.

What’s the target whotepoinr for ColorSync? Should be 65k
 
Under Picture->Color Adjust, thre is a SixColor list with lots of options. Is this the place to adjust?

Can't find ColorSync option on the monitor.

Things like Nightshift is even worse.

Have used several monitors with my MBP 2010 17" before. This is the most yellowish one. Haven't seen anything like that before. The Asus I got yesterday and the LG 38" bought few months ago did not have such issue.
 
I had a terminal (in black background) on this screen. When I moved it, I found that the screen area where I had the terminal app turned black. It was like half of the screen got toasted. Have used many monitors for 20+ years. Never seen anything like that. Are IPS LED monitors subject to burn-in?

Just to get something straight - IPS LCD with LED backlight. This is not an LED based display, as that would not need the in-plan switching (IPS) technology, which is an LCD related technology.

Regarding your colour issue as the original post was about, the monitor claims to have this feature:
Protect Your Eyes and View in Comfort

Flicker Safe and Reader Mode help maximize visual comfort by protecting your eyes from harmful blue light and reducing the flicker level to almost zero.




Reducing blue light sounds a lot like your issue.

Regarding burn-ins; LCDs generally don't burn in. LED panels can. But as stated, this is an LCD with an LED backlight

I have the product page in the original post. It is: IPS LED monitor.
 
Is it recommended to
Yes, i read that. But unlike what you may have been led to believe, it's an LCD. IPS in an LCD technology. LED refers to the backlight

So LCD with LED backlight monitors may have burn in issue?
 
Sorry I meant is it recommended to use monitors that have Flicker Safe and Reader Mode?

About the yellow tint issue. After using it for two days, it does not seem to be that yellow. When I first turned it on, it was like a mango.

Perhaps I got a lemon that has burn in issue. The unit is supposed to have a white case but when I opened the box, it is black!

Your eyes have got used to it! That's why we can't trust our eyes for judging colour!
A monitor will always take awhile to warm up. Typical up to 30 minutes.

As a general principle, I stay away from marketing slurs like that. Flicker safe I would assume just means that the power delivery in it is stable - reader mode just sounds like it is basically Night Shift, and to have that but into the display is neither a plus n'or a negative. I'd just keep it turned off myself.

Right. It could be that the panel just needed to settle in.

Can you return it and get a refund/new unit? Sounds like yours may be defective

Thanks. With all these issues, I will return it to get a refund.
 
If you just bought this monitor, it seems like it's defective. I would call the place you got it from and get it exchanged.

One check you can do is System Preferences - Display - Color tab. Make sure the right profile is selected. There is also an option to Calibrate. As noted above you won't be able to calibrate with precision, but you can get it close-for-comfort.

I have Dell and LG IPS monitors, and there hasn't been any issues with them, including burn-in and or (reasonable) fidelity.
 
Thanks. Just tried it. It is under 32inch LG FHD. I did a calibration as you instructed. No noticeable difference.
 
As others have said, sounds like it's defective and/or poorly calibrated, and that's a big physical display size for only HD (1920x1080).

I'd recommend - given that you're sensitive to the pixel density - you at least look at QHD (2560x1440) and drop the size down to a 27". I'm actually running QHD in 25" for the even better PPI (and 2X Dell Ultrasharp 2518s which have outstanding calibration OOTB, they even include a calibration spec sheet for each display).

Of course you can also step up to 4K, but that's a notable price jump for larger sizes (if it's a good quality display), and then you also have to consider what's driving it).

Thanks for the recommendation. I do both programming, writing and CAD design. It has been calculated by another forum user that I would feel comfortable with the text size at 4K on a 40-43" display. I am interested in the LG 43":

http://www.lg.com/us/monitors/lg-43UD79-B-4k-uhd-led-monitor

I am waiting for Apple to update the MacBook Pro 2018 as my current MBP 2010 cannot drive 4K display. I read that two new displays from LG will be released this month (one 4K and one 5K) but the screen size is about 32-34". It would be nice if LG could update the 43" to HDR and perhaps at higher refresh rate for possible gaming. However, there is no sign about it. My productivity has been limited with only the screen on my MBP.
 
Yeah, I can image the PITA-ness of doing code and/or anything graphic on just the internal display - my MBP stays "docked" 98% of the time.

If you're interested, you can use a DPI/PPI calculator like this:

https://www.sven.de/dpi/

That one has a bunch of pre-defined calcs as well. From there you can see the retina MBP 15" is ~220, and a the display you were working with was a low ~69 PPI. I've noticed that over 100 it starts looking a bit better, and over 120, while not "retina" PPI, it gets much better - especially if combined with a generally high quality display with solid calibration, good display tech, high refresh, good color reproduction, etc.
