A year ago I calibrated my new TV with the PS3 as a source. Once I figure out the HTDV should be set to Limited range (as does the PS3), everything went smooth.
I decided to connect my Desktop PC to the same HDTV, as I want to be able to play Games and watch movies directly from my PC.
Here's the setup:
- ATI Readon 4850HD Card
- On Catalyst I set "4:4:4:4 Limited RGB" instead of "4:4:4:4 Full RGB" when the Desktop is connected to the HDTV
- The video card only have DVI, so I'm using DVI to HDMI adapter
- I'm using AVSHD Calibration tool
Calibrating Brightness was easy enough. The issues started on the 3rd pattern (White Clipping). Using "Windows Media Player" and "Windows Media Player Classic" I'm only able to barely see 230 to 232. Change the Contrast on TV does nothing to the Flashing bars, but instead changes how "Strong" the white color is.
I tried VLC, and I got different results - with VLC I was able to see 230 to 234, but again - changing the Contrast on TV did nothing to the Bars.
I noticed another strange thing that happens. On the First Pattern (Black Clipping) I set the brightness so I can only see 17 and above. But when I'm checking the Brightness with the second pattern (APL Clipping), no bars are being shown at all. I have to play again with the brightness to make them visible, and that ofcourse breaking the First pattern (I can now see bars all the way to 4-5).
Clearly, I'm missing something Important here that clipping the whites.
I'm guessing the Video Players have different settings, and maybe that explains the delta between the results (which makes it all more complex because I can't really be sure that Calibrate the screen on VLC, will have decent results while playing a GAME for example).
