all Alienware screens definition & resolution comparison

Alienware laptops are known by their high resolution which is amazing but can lead to a difficult reading experience.


This is a table comparing the screen definition, aka resolution by inch, of all Alienware laptops and a 24.1" 1920x1200 desktop monitor:

Notice the bigger the resolution, the smoother the images. But at the same time, the smaller letters so take this in consideration.


Some conclussions:

• M14x (768p) - M15x (900p) and M18x have similar definitions
• M11x - M14x(900p) - M17x have similar definitions (about +15% compared to above models)
• M15x (1080p) gets the highest definition
• They all are considerably smoother than regular desktop LCDs, so even a 1366x768 M14x or a 1600x900 M15x are not "crappy screens"

Now lets talk about distances and reading easily. You probably want to perceive letters at a same size than you are used to on your previous laptop or desktop system.

Just note your horizontal resolution (for example 1920 if its 1920x1080) and how width is your current screen. Divide these and write down the result (pixels/inch). Compare it to the numbers in the table above.

But wait, distance is the other factor. Take your regular usage distance from eyes to your screen, and the distance you will/need to use with your new laptop (which should be smaller). Make a rule of three and try both of them to be as close as possible, considering this works as an exact inverse proportion. Twice the distance, half the definition should be. For example, 1meter 70pixels per inch equals to 0.50meters 140pixels per inch.

Cross-multiplication - Wikipedia, the free encyclopedia


Of course this works on both ways: you may want to buy your desired Alienware laptop and just guess to know what the perfect usage distance would be

Enjoy.

 

I had done a bit of this myself for a couple of displays, the comparison to a desktop 19x12 monitor is something I didn't think of though. Very informative!

 

Umm, I don't see my Alienware M17x screen resolution in your chart. It needs to be updated please.

 

Or you could take the two seconds and do it yourself. It's probably going to be almost identical to the 14" 16x9.

 

Alienware m17x R2 with 1920 x 1200 screen:

17" 1920 x 1200 133.1856 ~41.76%

Dp = sqrt(Hp^2 + Vp^2)

PPI = Dp / Di

Dp = Diagonal pixels
Hp = Horizontal pixels
Vp = Vertical pixels
Di = Diagonal inches

Quick and dirty calculation via wikipedia.

 

What about reaction time?? Does anyone have those for the AW screens? 2ms?? 10ms??

 

^^^^^^ THIS was missing from the chart. Please update it. Same rez as your 24" EXTERNAL monitor.

 

Only problem is there is more to a quality screen than resolution. The Color Gamut is only 45% on the M14x and M11x... While 60% on the M17x R3. The M15x with the RGB screen is 95%...

 

The M15x is Wled not RGBled. The M17x R2 was RGBLed.
I believe the only 2 that were RGB were the M17x R2 and the Precision M6500. That option has gone away for AW and Dell will no longer use RGB in the M6600.

 

M15x has had an RGB screen.

 

NO, the 17" panel 1920*1200 was the only RGB alienware has offered. I spent too much time researching this panel. Unless someone can show me data i missed that makes me eat crow!

 

jpg needs to be updated to show "M17x 1900x1200 RGB LED 17.3 inches" etc...please fix, thx.
