Calibration is the process of setting the monitor hardware settings (brightness, contrast) to their optimal state unless the monitor allows the hardware sensor (e.g. Nevertheless, I do understand what you are trying to say.įresh GPU LUTs are created after profiling, not calibration. The process of creating/utilising a LUT, whether GPU, or monitor based, is a form of 'calibration' - in just the same way as any manually applied adjustments might also aim to be. You appear to be confusing calibration and profiling. Some monitors (as you say) do indeed have their own LUT - but that is far less common, and certainly isn't a prerequisite to proper calibration using a hardware calibrator. In fact, the OP (IanYorke) is effectively modifying his laptops' GPU LUT, while he is adjusting his display driver utility's settings - in much the same way that a 'Spyder' (etc) would do. So, using a something like a 'Spyder' is perfectly valid, and normal, for almost any PC (as many tens of thousands of users already do). In most cases the LUT (Look-Up Table) produced by hardware/software based calibration is stored in the graphics card/chip within the PC (or laptop). The numbers that other people are using won't help you unless they're using the exact same laptop model.Ĭalibration really requires a hardware device such as Spyder Pro.Ī Spyder will help with profiling, but it won't help much with calibration unless your monitor offers internal LUT calibration. (which you linked) has good images, but don't view them in a browser save them to your local storage and use a color-managed image viewer to look at them.įifth, gamma/contrast/brightness settings are specific to each display. Don't use non-color-managed image viewers to calibrate your monitor. If you're using software that's not color-managed to view the calibration test images, then the software probably isn't using the ICC profile. If the profile isn't for your specific monitor, you shouldn't be using it it's not helping you.įourth, not all image viewing software will use your ICC profile. Third, where are you getting the sRGB ICC profile? A profile is meant to describe the characteristics of your specific monitor. Use the sliders to get the monitor as close as possible to displaying your test images correctly. Second, forget about the numbers the calibration software shows. Also, display uniformity is usually horrible on laptop TN panels. I'm not trying to be a snob, but even you mentioned the problems with tiny changes in viewing angle. What gamma, brightness and contrast do you have set?įirst, you're never going to get a good picture on a TN panel. I should probably just not worry and get on with it, but my curiosity is too interested to let it go.Ĭan anyone shed any light as to why my monitor appears optimally calibrated yet the brightness/gamma/contrast settings are so low (when compared to what I read online should be ideal)? General websurfing and looking at galleries of other photographers, especially on model shoots with dark clothing, appear fine. But pushing up the brightness or gamma only makes the scene noisy, so perhaps those scenes are just not too bright originally. Only some dark clothing in indoor scenes appear to not show the level of bright detail I might normally expect. Watching films and youtube also seems fine. The monitor passed fine except the gradient test revealed packed thin vertical lines of banding (which I haven't seen in photos or video yet), and the gamma test I didn't understand anyway.Īnd looking through my gallery of most-familiar photographs, they all look great: The one I link below seems to be the best one. The calibrations I did were the Windows 8 one (same as in Win 7) and a few online I found. But still, with these settings, and using the ICC sRGB with Hardware Calibration colour profile I was able to match up all my applications: Photoshop (where I'd switch to "use embedded profile" when opening an image), and the default settings on the likes of Firefox, VLC, Fastview, LCD screen of my DSLR etc.only the Windows Image Viewer seems to be a little darker than the rest. TN panels are a pain in the backside when calibrating, as the slightest change in vertical viewing angle messes up the gamma (eventually I'd like a nice Eizo IPS). My monitor is the TN panel from my new Asus G74SX laptop (type LGD02C5) which has a relatively modern Nvidia graphics card.here are the settings I settled on after a few monitor calibrations: And contrast generally around 50%.but not turned right down. I keep hearing that gamma should be 2.2 (or 1.8).but never as low as 0.67. These values sound theoritically too low off the ideal.
