Having issues with the apparent brightness of my Lenovo W500 (suspected Samsung display) in reasonable ambient light levels, I thought I'd try measuring the lux with a tool I found at ->
http://www.tuug.fi/~toni/serendipity/index.php?/archives/12-Luxus-light-meter-desktop-widget-for-N90... -- just for a more objective, albeit uncalibrated view on brightness.
In each case I placed the proximity sensor directly over the panel, so it was around 5cm "in" from the edge & displayed an all-white window.
Here's my rough results
Lenovo W500 (full) R=083 L=063 T=060
Dell 2005fp desktop (normal) R=151 L=155 T=142
old? HP 17" 4:3 (normal) R=157 L=143 T=180
Dell Studio 15 1920 laptop led (in dark room) R=104 L=111 T=110
Dell Studio 15 1920 laptop led (full) R=214 L=212 T=226
Dell Studio 17 laptop led (full) R=300 L=314 T=297
? HP 19" unknown (low lighting) L=098 R=107 T=113
? HP 19" unknown (full) L=138 R=153 T=162
From this "comfortable" is IMO in the region 130-150 - the W500 fals way way below this.
Has anyone else measured?
What's reasonable?
I believe the spec is around 175-180 -- but that's obviously a calibrated test
The dell 2005fp is rated at 300 yet I score 150 above (though this is NOT on max, just normal)
The dell studio 17 is rated around 317 on full -- and the score above shows this as close
I can only conclude therefore my measurements are in the right ball park
The W500 is on full brightness & using the appropriate monitor.inf under win 7
What I should really do is have a proper colorimiter calibration and measurement done.
The "spec" of the W500 panel is 180-200 I believe - it's clearly not fair to use the numbers literally, but something is very very wrong.
Does this suggest my panel is faulty? To be honest I don't think I've seen a "good" W500 but I wonder if it meets the spec?
Anyone else fancy measuring a "current" laptop for comparison -- especially any other W500 owners (some of which have samsung panels, some have LG panels)
