Nec 60" TV Plasma

[Anonymous]

This week I am going to calibrate Nec 60″ Plasma TV 720p it is friend of mine and the Co-Producer of The Chronicles of Narnia to check that on the AccuPel DVG-5000 well I set it 720p or 1080i for video test patters?

because this is the first time to calibrate 720p display

it is actually 758 or 768 not 720p. I would calibrate for 1080i.

check to make sure that 480i 480p 720p and 1080i all use the same white balance controls.

What you have is a wide XGA display. Such resolution comes from the computer industry, rather than the video industry. Large format WXGA displays are fundamentally targeted toward the digital signage and large computer/graphics monitor market. Most likely the resolution is 1024 x 768 (stretched wide with non-square pixels- usually smaller display sizes), 1280 x 768, or, hopefully, 1366 x 768. In case of the latter resolution, you would theoretically preserve more resolution from a 1080i video signal than a 720p video signal. Most critical in displaying actual picture information best, will be the quality of the scaling in the display itself. Only trial and error, with comparing native 720p versus 1080i resolution patterns, would reveal by eye which signal would be best to feed the display. Some scaling processors might handle a native progressive signal better than an interlaced signal, resulting in less digital scaling artifacts, especially with motion. You would have to determine what the best case scenario is for that particular display.

yes its 1366 x 768 and support 1080i patters but the problem that I did not have to access the service menu for the Color Management
the only to adjust is the CMS and I send email to NEC but no reply at all so I adjust what I have in the menu.

I have the report but the problem I can’t attach it saying error in this page but other way the client that is the Co-Producer he saw the different
the picture much sharper and better color then was before.

I try attach the report because the green was out of way!!

there is no color management. All controls (front panel and white balance) are available in the user menus.

(there “maybe” a CMS in the user menu, but it there is dont bother using it).

The more I consider this, the more surprised and unsettled I am about a movie producer using such a display! Perhaps you know more about the situation, but he should be paying for calibration on a decent monitor. My suggestion is a similarly sized Panasonic Premium Professional 1080p plasma monitor, with an outboard processor for scaling and color management.

I check with NEC and they told me this :

Unfortunately NEC do not release service information. All settings on the unit which are accessible to the end user are detailed in the User Manual. Do you require a copy of the User Manual?

What they send me is the manual but can’t see color management that I can adjust.

[Gregg Loewen]

there is nothing to access in the SM of this display. Access the gray scale controls by hitting enter after selection the white balance preset.

Do not use the color management options on NEC.
