Detailed screen specs

Are there any programs that tells you the detailed specs of your screen? Like brightness, contrast ratio and color gamut.

 

Try something like a Spyder Elite 3 software/hardware combination.

 

To add to what tilleroftheearth said, there's nothing that can do this for free because you need a piece of hardware to make the measurement. The cheapest (and least accurate) option is a Spyder 3 Express, which you can find for about $70.

 

Ah that sucks ;< I was more thinking about something simple like gpu-z. Hwinfo32 shows pretty much everything other than brightness, contrast ratio and color gamut, weird.

 

You need a calibrated 'hardware' component because even though a video card may output the proper voltage/current for a specific colour/shade of gray it doesn't mean that the monitor's electronics won't interpret/mangle that information to something else. Not to mention the vast variability of the actual LCD panel(s) themselves.

No software solution will ever give what you ask for. Ever.

At least, not what comes off the actual monitor (vs. what's 'fed' to it).

 

The Spyder Express won't tell you a lot - it will pretty much only calibrate the screen.

Even a Spyder 3 Professional doesn't tell you a lot -> so tilleroftheearth is right that you need a Spyder Elite - on this note, version 4 is out.

 

I see, but all I wanted to know is the screen's(and the screen only) brightness, contrast ratio and color gamut given by its manufacture, they should be a set value. I'm wondering why they have infos like manufacture date and even physical size of the screen, but not brightness, contrast ratio and color gamut??

 

The problem is, these are, to some extent, useless values.
-> Look at screen brightness - the brightness of your surroundings will influence how bright you need your screen. (The Spyder 3 has a brightness sensor)
Further, these specs will ever so slightly change with time.

Next point: GPU, colour profile - this is how your screen is controlled when using a Spyder, the colour profile for the screen is adapted to make it accurate.
-> whatever you set in your GPU will therefore influence how your screen looks, this can be changes by something like a driver update.
-> Look at the SZ's screen - it looks lovely and bright - calibrate it and it turns yellow. Well, nowadays I say uncallibrated it is blue.
This hits the next issue - our eyes can tell us different colour tones are white -> this is colour temperature.

So what good is a manufacturer specification?

 

What if I'm deciding between two screens and I don't have either one on hand? ;p It may not be absolute but the one with higher values will most likely look better when put onto the same system.

I'm not into the professional area but that were interesting to read

 

In this case the best thing to do is to actually head out an look at it

Another point you need to remember is that manufacturer specs are generally "over the top".

 

Even though you have a valid point that contrast and brightness on a specific screen are set values just like the screen size (if we don't count for the minor differences between different batches), these values are just not stored in the LCD's firmware. So your best bet is to check the net for reviews and specifications, or if possible have a look at the screens side by side and decide which looks best for you.

 

There's a tool that'll tell you just about everything about your monitor and it's free.

EnTech Taiwan | Utilities | Monitor Asset Manager

There's also another tool (also free) that is able to edit the info stored about your monitor or HDTV. Usually this will fix issues like "no sound over HDMI" when using the newer nvidia desktop cards.

 

There is one workaround. Run Lavasys Everest Ultimate. Find out what panel you have. Search for your panel on sites like Notebookcheck and Notebookjournal. They have done many measurements.

In your case you seem to already know what panel it is. In that case you could search for reviews of the Dell XPS 14 with the same panel.
