Monitor for Photo Processing


I recently went through the process of choosing a monitor specifically for photo post processing – this has taken me over a year of research to find something that was suitable, and inexpensive.
Hopefully sharing my experience may be helpful.

Many know that in LCD technology, the panel to aim for is IPS (in-plane switching) because it is capable of showing more colors/wider color gamut, and have wider viewing angles with consistent and accurate colors.

So wider gamut/more colors is desirable –
an examination of monitor specs show things like 82% or 72% gamut –
but without any indication of what gamut or color space.

Although it would seem more colors or wider gamut is better –
so is 82% better than 72%?
BUT 82% or 72% of what?

That's when I realized those figures do not matter -
what was really important to me was the ability to display 100% of the photographic working color space -
ie: 100% sRGB

Even a gazillion% gamut is absolutely useless, if it cannot display all the sRGB colors ie: 100% sRGB.

OK some may argue that a monitor would be superior if it can display AdobeRGB or NTSC color space(s) -
but only if it is 100% sRGB capable in the first place –
since the displayable end result for the web and most printers is standardized on sRGB.

Doing searches of 100% sRGB IPS – will find monitors, and some surprisingly were not very expensive.

That is when I realized that some of those monitors actually had an sRGB preset that set a factory calibrated 100% sRGB – this was better than expected –
since that virtually may mean separate monitor calibration was not as critical as it used to be.

This discovery was HUGE.

Were there differences in IPS panels? – well of course, only a few months ago there was general opinion that cheap IPS monitors were not really recommended.
3 Reasons Why You Shouldn’t Buy A Cheap IPS Monitor

So the LCD panel technology was important too – not just blanket approval of any generic IPS.

Fortunately we have currently many smartphones with stunning very high pixel density screens -
have some of this new technology made it way to computer monitor screens?

Some of those names were AMOLED (Samsung) and AH-IPS (LG).

As far as I know there are no AMOLED monitors -
BUT – there are AH-IPS monitors now.
and searching on AH-IPS finds that LG claims AH-IPS been certified by Intertek as having accurate colors (this is really important)

Searching for AH-IPS 100% sRGB does find monitors, and in fact some inexpensive ones.

Just to set the scene –
Dell UltraSharp U2713HM – this is a 27” screen, but at $650-700 street price - hardly cheap.

But there were also:

ViewSonic VX2270Smh-LED 22" Frameless LED Display

ViewSonic VX2370S-LED 23" Frameless LED Display

These actually were some of the lowest priced IPS monitors available.
This was like a dream come true – monitors based on the latest AH-IPS, with 100% sRGB factory calibrated preset.

I bought the 22" ViewSonic VX2270Smh-LED since I have limited desk space, and prefer a higher pixel density.

The first thing I did so to set the monitor for 100% sRGB -
which was just a simple set on the OSD to sRGB - and that was it -

Then I went to the various on-line monitor calibration sites to check the monitor -
it passed any and all the tests I could throw at it with ease.

This is a handy reference page that collects together the most useful calibration sites -

That includes the sites that I had found the most useful:
Photo Friday: Monitor Calibration Tool
and
Lagom LCD Monitor Test Pages

Some of this has been discussed in the thread:

starting with Post #37

Hope this was of some help.

Vincent,

Great post. You obviously put a LOT of time into your work and purchases. The other thread you link to bears this out. LOL!

I am on my second Dell Ultrasharp 30" IPS monitor (now: U3011). I researched a lot at the time and liked the first one so much when the latest came out (with sRGB and more color settings) I simply sold the first and upgraded. I like the LARGE monitor so I don't have to use two, and I can edit my common portrait images without a clumsy rotating monitor.

I spent 8 times on this than what you did. But who's counting.... ;)

I think I'll spend some time on those other useful links.

Thanks!

Coop

Coop thanks so much for your kind comments.

You make me envious with your Dell UltraSharp U3011

In the course of my postings many gave me much useful information, including a site that you may already know about:
TFTcentral.co.uk

They have really good and detailed monitor reviews
and in their news I noticed:

Further Dell U3014 Information Available
Dell's new UltraSharp 30" monitor will be called the U3014 and that it should be available in the first quarter of 2013. We now know a few more details about the screen which we will share with our readers. Like the existing U3011 model, the U3014 will be a 30" screen with 2560 x 1600 resolution (16:10 aspect ratio). We also know that like the recently released U2413 and U2713H models the screen will use a GB-LED backlight system offering a wide gamut and coverage of 99% of the Adobe RGB reference space. This equates to ~103% NTSC and covers 100%+ of the sRGB space. Interface wise the U3014 will offer DisplayPort, HDMI and Dual-link DVI (HDCP supported). It will also have a 4 port USB 3.0 hub, full height adjustable stand (tilt, swivel, rotate and height) and an integrated card reader.

While the above information is confirmed, we can also speculate on a few likely features. We expect the screen to be AH-IPS based and using LG.Display's newest LM300WQ6 panel. The spec is therefore likely to have a 6ms G2G response time, 1000:1 contrast ratio (2 million:1 DCR expected), 350 cd/m2 brightness and 178/178 viewing angles. The panel offers a 1.07 billion colour depth and according to the spec sheet for the LM300WQ6 panel this appears to be a 10-bit module without the use of Frame Rate Control.

The U3011 will be replaced by this new model and so is going end of line (EOL) now. The U3014 is still anticipated to be released in February and we will keep you up to date via our Twitter feed as we know more.

So the newly announced U3014 is based on AH-IPS and has close to 100% AdobeRGB and obviously 100% sRGB.

Wider gamut is probably not necessary for me - as I work in sRGB and produce everything in sRGB -
as it is the de-facto and accepted worldwide standard color space.

That's why I was so pleased that I got my monitor that does 100% sRGB on a factory calibrated preset -
so I didn't have to do any calibration (for now)
and it was at a price that's barely above the lowest budget LCD monitor
and actually one of the lowest priced IPS monitors.

On top of all that - it's AH-IPS - that is not only just the latest "hot" technology -
but also had been certified as more accurate in color -
since I wanted a monitor mainly for doing photo processing - that was really important to me.

Thanks,

I need to qualify my post thread from what I have learnt since.

First this really is more about the Budget end of monitors for photo processing -
there are many worthy monitors that are hundreds, if not thousands of $$ more.

I am not, and cannot really address that end of the price range.

The reason why I was so enthusiastic about the ViewSonic VX2270Smh-LED 22" Frameless LED Display -
is mainly because it had 100% sRGB on a factory calibrated preset -
so that setting virtually makes initial calibration redundant.

Acknowledge: calibration especially if optimal accuracy is required, and monitors will drift with age - so making re-calibration necessary

From the very comprehensive and thorough reviews at reputable sites such as:
LCD and TFT Monitor Reviews
PRAD | Review
Reviews of HDTVs and monitors - FlatpanelsHD

On their tests, the factory preset sRGB have been satisfactory.

That's where AH-IPS was important -
LG claims AH-IPS has been certified by Intertek as being color accurate.

This means the panel itself is intrinsically more color accurate - so it is easier to have 100% sRGB -
and unless there is evidence of faster deterioration of the panel itself -
it probably stands to reason that it would maintain its color accuracy better than other IPS panel types.

Hence the importance of AH-IPS, and obviously 100% sRGB on a factory calibrated Preset.

I have heard feedback that 100% sRGB may only refer to the gamut -
however at least on this ViewSonic VX2270Smh-LED the preset seems to disable any other adjustment even brightness and contrast -
so it appears that the preset sets sRGB color space -
again those reviews of other monitors - especially the ones that use AH-IPS seems to show the sRGB preset/emulation are very satisfactory.

Short of having a calibration tool
I can only do my checking by eye - as mentioned already:

A handy reference page that collects together the most useful calibration sites -
5 Online Tools to Help Calibrate Your Monitor

The pages and images I found most useful for checking my monitor:

Black and white levels - I like the Photo Friday: Monitor Calibration Tool
PhotoFriday_zps29942905.jpg

I can easily see the black levels A, B, and C, and white levels I can also see easily X,Y, and Z

In terms of Color - I looked at the tft.Vanity.dk Online Monitor Test - Color Range Multiple
tftVanity_dkMultiColor_zpsb2e77aa4.jpg


and also the Lagom.nl Contrast test
lagon_nl_Contrast_zps836f3185.jpg

I can see each color segment easily.

For continuous tone I used tft.Vanity.dk Online Monitor Test - Trailing Main test
tftVanity_dkTrailing_zps20b382d6.jpg

the tones were continuous.

Like I said, short of actually using a calibration tool - by eye the monitor seems well adjusted on the factory preset for sRGB.
(note: calibration tools are $150-$250 street price - my monitor was only $160!)

But I do take the point, a sRGB preset may not be as accurate as it can be potentially, and once the monitor ages things may shift - but for now it is brand new and things "seem" OK - within reason.
I am not against calibration - just for now I do not have the capability, other than by eye.

I looked at those monitor review sites - in particular the AH-IPS panel monitors, since that is the technology this ViewSonic VX2270Smh-LED is based on - those monitors (eg: Dell U2713H, Dell U2913WM) seem to do pretty well on their sRGB factory preset - seems almost to me to be within experimental errors - or at least someone inexperienced in monitor calibration - like me, for example :o

Having said all that, I am impressed with this budget ViewSonic VX2270Smh-LED monitor -
as it were - straight out of the box with its sRGB preset capability.

Awesome score. I think I'll purchase four of them, and scatter them all over my office. ;) Jeez, at THAT price....! LOL!

I can see the distinction in every scale above. Cool stuff.

Thanks for such an invaluable thread. Really, you did all the work for anyone interested. :thumbup:

Props. Good luck on yours!

Thank you again Coop for your kind words.

I just realized from elsewhere I may have caused some inadvertent confusion by the imprecise use of terminology:

To clarify -
The ViewSonic VX2270Smh-LED is specified as 100% sRGB gamut -
but it also has a sRGB Preset which is supposed to be factory calibrated -
I sometimes may have confused the matter by referring to it as 100% sRGB Preset

No, the monitor is spec'd as 100% sRGB gamut,
and separate from that, it has a preset for sRGB color space/emulation.

I hope that is clearer.

and it is on the sRGB preset that makes the monitor seem well adjusted - "passing" all those on-line monitor calibration images.

My apologies if I caused any confusion.
