DVE Pro - Nice gamma patterns and good sweep patterns. I like AVIA Pro more for grayscale. High Def discs are great for HTPC and WMV, although I also use Display Mate which has been out for a long time. If you have an HTPC for high def and have calibration equipment it would be worth getting. A user could use this as a cheap signal generator, especially with an ISF approved video card. Other than that this isn't worth the price for an average user. |
Hi Bob,
I am a total newbie to advanced calibration, as I just bought a GMB EyeOne Pro spectroradiometer and UMR's i1 Pro software. I will hopefully be profiling my first projector later today and have a few question, if you don't mind.
In reference to your above statement, if I don't own a generator (which I don't), how else would I calibrate an input for HDTV? I do have a few HTPCs here loaded with Nvidia Geforce 6600GT cards, so I think I have the right horsepower and hardware to use the DVE Pro HD patterns. BUT wouldn't any calibrations performed with those discs only be valid for HD material played from the PC? That is, I have a total of 5 HD sources (Dish 6000 - component, Dish 811 - DVI, MyHD - DVI, and 2 HTPCs - either DVI or RGB) and 2 projectors (InFocus 7210 and Optoma H-79), so how would I calibrate:
1. The HD component output of the Dish 6000 (it does not have DVI)?
2. The DVI output of the Dish 811?
Wouldn't the calibration that I perform using the DVE Pro WMV patterns through the PC only be applicable to HD playback through the PC? How would I calibrate the inputs on my projectors that are connected to the 2 Dish units?
Some more newbie questions:
1. I assume that analog inputs need to be calibrated to the individual source components, as they differ from one component to the next. Is this also true of DVI?
2. On any one projector input, does each signal
resolution need to be calibrated individually (like 480i, 480p, 720p, and 1080i from an upscaling DVD player)?
3. I already own the basic versions of Avia and DVE. Do I have enough to get started? (This color issue with Avia has me concerned, as grayscale calibration is why I bought all of this stuff to begin with).
4. What patterns will I need? My assumption is that I will need IRE windows from 0 to 100 in 10 IRE increments, as well as the standard reverse gray ramps and pluge patterns. Any others?
5. I've seen people talking about taking measurements directly from the projector vs. reflected off the screen. Logically it seems to me that I would want to measure off the screen to take into account the effect of the screen, as it is those reflections that my eyes will see. Is this correct?
Sorry about all of the questions, but I figured "While you are here..."
