For now use one of the THX modes.
Download the free AVS HD 709 calibration disc or better still Ted's calibration disc.
Even using only a calibration disk needs some basic knowledge of the display controls etc. and the purpose of using them.
Can we say that by using a calibration disk only that a display is calibrated? No, this requires meter/software/knowledge, but can improve a lot the factory default settings and it’s better solution from copying display settings from web.
We can say that using a calibration disk without having meter/software you can do plenty of things, for example using Ted's LightSpace CMS Calibration Disk
1. Display a Brightness Pattern to set the Black Level (Brightness Control) of the Display; to prevent crushing of shadow details or raised black levels.
2. Display a Contrast Pattern to set the White Level (Contrast Control) of the Display; to prevent color detail clipping up to peak white levels and above reference white level color shifts/discoloration. The limitation to this is that you don’t know you peak output without a meter/software to measure the 100% White patch.
3. Use Sharpness Pattern to prevent edge enhancement (halo/ringing effect) or soft contouring (blurring of the image details).
You can check using that Sharpness Pattern some display settings like: Reality Creation, Noise Reduction, MPEG Noise Reduction, Dot Noise Reduction, Noise Filtering, Detail Enhancer, Edge Enhancer, Super Resolution, Digital Clear View to see how they are affecting your image resolution.
4. Use Color Clipping Pattern to prevent clipping of each color channel (RGB), this sometimes can be fixed be removing some clicks from the contrast control also.
You can check display settings like Live Color, Dynamic Color or Color Enhancer etc.
5. Display a Grayscale Ramp Pattern and find by swapping thru the available color temperature modes (normal/warm1/warm2 etc) of your display; which looks more neutral to your eyes. (It's guessing by the user selection), but Don’t try to fix the RGB Balance based to your eyes and tweak the RGB-High/Low Controls without meter/software.
6. Display a Grayscale Full Step Pattern and check your various enhancements controls of your display; Advance Contrast, Black Tone, Black Correction, Advanced Contrast Enhancer, Auto Light Limiter, Clear White, Dynamic Contrast, Cinema Black, Smooth Gradationetc. to have a better view of the problems they introducing and to realize why you need to leave them untouched to prevent new problems. (no smooth color graduations, distortions, discoloration, clipping, banding, posterization, crushed shadow details, raised black levels etc.)
7. Display a convergence pattern to find which mode of your TV provides you the 1:1 Pixel Mapping, to be able to view the correct full 1920x1080 pixel resolution of your display.
We can say that by using only a calibration disk we can’t meet the REC.709 standards, this requires meter/software, but it will be a good improvement for a small amount of money or by downloading a free one from web.
Also is an introduction to what a display calibration can do, the user maybe be interested to buy meter/software to do DIY or hire a pro for this job.
But by using only a Calibration Disk you can't set your peak light output, perform RGB Balance of your grayscale, calibrate your Primary/Secondary Colors (Hue/Saturation/Lightness), fix your gamma levels etc. for REC.709 without a meter/software...... but for sure you can improve your image in case you do the above steps with the correct way.
There available a lot of videos online to help for the first steps any newcomer to calibration world.
For a starters it's better idea to get the free AVSHD with the video examples or the Disney WOW where it features a lot of video examples too before moving to a more complex/advanced disk like Spears & Munsil or Ted's LightSpace CMS Calibration Disk.
I recommend Ted's LightSpace CMS Calibration Disk to enthusiasts or those who are coming from other calibration disks. Experienced users will understand better the value of that disk and the the purpose and what to look for by viewing the 152 Color Reproduction Patterns
, to evaluate visually any 1D/3D LUT display/projector.
For a starters it's better idea to get the free AVSHD with the video examples or the Disney WOW where it features a lot of video examples too.
But you can find some basic patterns to pre-calibrate your display by free downloading theTed's LightSpace CMS Calibration Disk (Free Version)
which is a 'lite' version of the Full Version. This required a black Blu-Ray Disk to burn it). by downloading the Free and popular AVSHD Disk
you can burn it using blank DVD disk at AVCHD format which is compatible with blu-ray players.
