Dell m6400 RGB LED Refresh Rate

Can anyone tell me what the refresh rate on the RGB LED screens that Dell is putting in their new m6400 precision line? Is it the same 60hz that their screens usually are or is it higher now that they are using LED?

I need to know this answer to decide on if it will work for my application. (viewing stereo images)

Thanks,

From the manual:-

Type (active matrix TFT) 17 inch, WXGA+ LCD,
17 inch, WUXGA, LCD or RGB LED,
RGB LED Edge 2-edge glass
Active area (X/Y) 367.3 X 229.5 mm
Specifications 23
Dimensions:
Height:
WXGA+/WUXGA (CCFL) 245mm (9.64 inches)
WUXGA (LED) 248mm (9.76 inches)
Width (WXGA+/WUXGA) 383mm (15.08 inches)
Diagonal 432mm (17.0 inches)
Maximum resolutions:
WXGA+ (CCFL) 1440 x 900 at 262 K colors
WUXGA (CCFL) 1930 x 1200 at 262 K colors
WUXGA (LED) 1930 x 1200 at 16.7 M colors
Operating angle 0° (closed) to 152°
Refresh rate 60 Hz
Viewing angles:
WXGA+ Horizontal 40/40
WXGA+ Vertical 15/30
WUXGA Horizontal 60/60
WUXGA Vertical 45/45
Pixel pitch:
WXGA+ 0.191 mm
WUXGA 0.225 mm
Typical power consumption (panel
with backlight):
WXGA+ (CCFL) 6.46 W (maximum with no inverter losses)
WUXGA (CCFL) 9.5 W (maximum with no inverter losses)
WUXGA (LED) 15 W (maximum)


Incidentally, the response time is great on these- Perfectly ok for gaming. i've seen no ghosting, although I have seen a slight rainbow effect when looking at white text on black background.

 

Thanks for the info.

I don't know much about screens and refresh rates, but are there currently any laptops out there that have higher refresh rates? Preferably around the 100hz range? In addition are there any any external LCD screens that do 100hz? Right now we use 21" CRT monitors which meet our refresh rate needs.

Thanks for you help.

WUXGA is 1920x1200 not 1930x1200
Pixel pitch has to be turned around
What about the power consumption? LED drains the most power??

 

For external pro stuff with 120Hz refresh rate you can check:

I would be surprised if it couldn't go higher. All LCD screens are coded to latch onto 60Hz, even if the LCD timing itself can handle much more. All that means is that the LCD's EDID info is telling windows to use 60Hz.

I'll try and remember to force mine higher with the nvidia drivers and see if it handles it, but all I'll be able to tell you is whether it rolls with the new setting or blanks out.

I suppose it's possible for the LCD to be able to handle a higher refresh but the data connection not to... I know you need dual-link DVI to go above 1920x1200 on an LCD panel, but I don't know if you need it to go above 1920x1200x60Hz, or if you just need it to go above 1920x1200.

(i.e. I don't know if it's a data rate issue or a pixel dimensions issue.)

 

I am very interested to know the outcome. Currently using dual 21" CRTs for this reason.

 

Thanks. If you know of any others please post.

 

Did you try it? I'm curious to find out how it did.

 

Have you tried RivaTuner? (I think that is what it is called)
