LCD QUESTIONS

I have supposedly one good screen for editing and one not so good. My good screen is an IPS made by LG, my not so good screen is a TN from Dell. I have listed the model numbers and links to the specs below. I shoot tethered, the image looks so much better on the cheaper screen, image quality, color, and brightness than the better IPS screen made by LG. Color, clarity and brightness beat the IPS screen all day. I want to be as accurate as possible with my images. Could anyone maybe explain why out of the screens I have, the cheaper one is better in viewing quality than the more expensive one?


If I would invest in newer screens what would you suggest that would not break the bank that is around 25" or larger?

Thank you!

That is odd, but I will point out that the resolution on the LG is very low for a 27: monitor,. like really low. I don't think that should have any bearing on your question though.

But, Jake, both monitors are 1920 x 1080 Resolution.

Since the same pixel count is spread across a 27" monitor vs across a 21" monitor, the eye could be perceiving the bigger pixels of the 27" IPS and interpretating that is 'not better'.

Also, OP, have you adjusted Brightness and Contrast to NOT FACTORY settings, which are set up to look good in a bright light retail store setting where so many do their monitor choice. Maybe that is biasing your appreciation of the 21" TF monitor.

I did adjust the brightness to see if I could match the Dell screen, What I ended up with was a blown out screen, way to white and bright.

Just perhaps it is the DELL that is wrongly adjusted, and it should be dialed BACK to not be so contrasty and bright?!

The LG is super cheap very low quality consumer monitor, it's IPS only because LG make IPS panels, but this is about as bad and nasty as an IPS panel can get.
The Dell on the other hand is an expensive and high quality business grade monitor, it might be a TN panel, but it's about as good as TN panel can get.
But the biggest difference is the Dell has a backlight capable of producing the full sRGB colour space while the LG has very pour quality backlight and can only produce about 72% of the sRGB colour space. Basically it's rubbish.


A good replacement for the LG would be a Dell 2412, it's about as a good a monitor can get while still being affordable.
Beyond that you have to start looking at dedicated monitors for photography and design use, BenQ offer excellent value for money, or find a gaming monitor that also has a good reviews for image quality.

SCREEN 1
LG 27MP67HQ
Color Gamut sRGB 72%

SCREEN 2
DELL P2212HB
gamut of 82%
with a footnote that reads "Color gamut (typical) is based on CIE1976 (84%, 82%, 82%) and CIE1931 (72%) test standards on the P2312H, P2212H and P2012Hmonitors respectively"

Another relevant point would be to calibrate your monitor...I am NOT the color space expert, but I would shoot for a monitor with a higher color gamut, and then calibrate it. Color gamuts in terms of the relative range of color from narrowest to widest would be CIE 1976 < sRGB < AdobeRGB.

I'm inclined to agree with you Moppie. I am amazed at the quality of picture between the Dell and LG I am experiencing now. If I had known how crappy the LG was, I would not have purchased it.

I believe a 27in screen needs to be 4k resolution, then add the other quality goodies like color gamut and back lighting and the image becomes amazing.

It doesn't need to be any particular resolution, but traditionally the best 27in monitors have been 2560x1440 and newer ones are usually 4k.

However, a 27in at 2560x1440 has roughly the same pixels per inch as a 4k 40in TV.
