Does anyone have the actual tech specs for the screen itself
in reference to the 24" Imac (response time, etc.)
The 24" ALU iMac's display panel is an *LG.Philips LM240WU2-SLB1*.
According to TFTcentral, it's an 8-bit S-IPS panel. For more specs see:
Great specs, but the specs don't say anything about iMac's problems with
uneven backlighting. The white 24" used the LG.Philips LM240WU2-SLA1,
and had a gorgeous display -- as does NEC's professional LCD2490WUXi.
Check the specs, but also check some [24'' ALU iMac screen photos.|http://picasaweb.google.com/TheLooby]
How do you think the screen on the 24" Imac compares to this HP 24" monitor?:
I don't have a mfgr's part number, but it uses a 6-bit TN panel. Faster
than S-IPS, but significantly poorer viewing angles. OTOH, it probably
doesn't have the brightness gradent problems common in ALU iMacs.
For $75 more, HP's LP2465 and Dell's 2407 have superior 8-bit LCD panels,
and much better warranties (3-year & 5-year versus 1-year on the w2408).
I'm sure there are many other good (or better) choices as well, but I haven't
been monitor-shopping lately.
An S-IPS panel is a true 8-bit panel and the physical construction is different from that of the 6-bit TN panel used in the 20" model. It is capable of more precise graphics and displays the full range of colors, whereas a TN panel uses dithering (electronic trickery) to fool the eyes into seeing more than is actually there. If the HP display you indicated uses a TN panel, I would expect you to get better graphics quality from the 24" iMac.
Isn't an IBS panel better than a TN panel? Meaning the Imac screen
is actually better than the HP one I linked?
A good S-IPS display is better than a good TN display, but the best
S-IPS matrix ever manufactured can easily be turned into a POS when
mated to badly designed backlight, diffuser, or inverter components.
[My 24'' ALU iMac|http://picasaweb.google.com/TheLooby] had excellent color and viewing angles, but it also
had an intense hotspot on the left side of the screen. Nothin' wrong
with the LCD matrix -- but Apple managed to FUBAR the backlight.
...kinda like a 12-cylinder Ferrari, with 'only' one broken piston,
I spent a lot of time at Best Buy yesterday comparing both screens I mentioned in my initial post. They both suffer from serious glare issues in the light, but the Imac wins hands down simply for the fact that there is a glass covering on the screen itself. It really makes a difference, at least in my eyes and presentation wise, when comparing the HP and Imac screens.
