Using SwitchResX, as suggested in the related H-IPS thread, i found my WHITE 24" C2D, purchased 27 Jun 2007 from an Apple Store, has the coveted LG Philips H-IPS panel rather than S-PVA seen in earlier editions!! Here is the SwitchResX data: EDID Version........1.3 Manufacturer........APP Product Code........26012 (659C) (9C65) Serial Number.......168xxxx Manufactured........Week 0 of year 2006 Max H Size..........52 cm Max V Size..........32 cm Gamma...............2.20 DPMS Supported Features: ------------------------ Display type: ------------- RGB color display Input signal & sync: -------------------- Digital Color info: ------------ Red x = 0.640 Green x = 0.290 Blue x = 0.146 White x = 0.313 Red y = 0.340 Green y = 0.616 Blue y = 0.069 White y = 0.328 Established Timings: -------------------- Manufacturer Reserved Timings: ------------------------------ Unknown timing 3 Standard Timing Identification: ------------------------------- Monitor Description blocks: --------------------------- Descriptor #0 is Timing definition: Mode = 1920 x 1200 @ 60Hz Pixel Clock.............156.00 MHz Non-Interlaced Horizontal Vertical Active..................1920 pixels 1200 lines Front Porch............. 48 pixels 3 lines Sync Width.............. 32 pixels 6 lines Back Porch.............. 80 pixels 36 lines Blanking................ 160 pixels 45 lines Total...................2080 pixels 1245 lines Scan Rate............... 75.00 kHz 60.24 Hz Image Size.............. 470 mm 300 mm Border.................. 0 pixels 0 lines Sync: Digital separate with * Positive vertical polarity * Positive horizontal polarity Descriptor #1 is Manufacturer specific data (not interpreted here) Descriptor #2 is ASCII data: LM240wu2-sLA1 Descriptor #3 is Monitor name: Color LCD
Awesome! Now, someone needs to run this program on a 20". I guess I can do it when I go home after work, if someone doesnt beat me to it.
That would be great (because information is useful!), especially if people do it for other recent monitors: new-20, and also white-20 and new-24. But where in the info-readout does it say "LG Philips H-IPS"? Does this require extra knowledge and interpretation, as when you say "Manufacturer specific data (not interpreted here)" near the end? Craig
Descriptor #2 says LM240wu2 which is the model number of the LG Philips display, the same used in the new iMac 24".
Not being sarcastic but could someone please tell why is knowing about the LCD design so important? What is an H-IPS panel anyway and why should anyone care? I'm currently waiting for my iMac 24 to ship and just want to know is this H-IPS panel something I need to be concerned about on my iMac?
These panels are considered best for those who do critical photographic work because their projection angles are such that you do not have perceptual fading at the top and bottom. The larger a panel is, the more of a problem with fading.
I've had my 24" iMac for about 6 months now...build to order at the time. I just pulled the data using SwitchResX and it would appear that my iMac also has the panel in question... It doesn't mean a lot to me but I find it delightful none the less. Cheers, ... Data below.

How do you know that "LM240wu2 = LG Philips = H-IPS"? googling "LM240wu2" brings up info about Philips (mainly from forums, which say it's H-IPS) but how do they know? Is there a database with information about the types of displays used in various models of Philips (and Dell, Samsung,...) or is it available on manufacturers' websites? Or is it from "various sketchy sources" as in #31-36 and 41 of http://forums.macrumors.com/showthread.php?t=344204&page=2 ? Six days ago, prs86 said "someone needs to run this program on a 20. I guess I can do it when I go home after work, if someone doesnt beat me to it." It would be useful if someone with each monitor (aluminum and white) used SwitchResX (shareware with 10-day free trial period, http://www.madrau.com/html/SRX/About.html) to get data that can be decoded. (but is it obvious "what to do" after downloading the program? a "read me" user manual is available, but it's long) I would especially like to know what the white-20" is. Craig
This is interesting. Does anyone know if this particular lcd panel would be in all the last revision white 24" iMacs ? So, if I bought a 24" today from the last stocks in my local big box retail computer store, I should probably get one with that panel?
24" iMac AL uses LG/Philips Model LM240WU2 (SL/B1) 24" iMac White uses LG/Philips Model LM240WU2 (SL/A1)
My white 20" iMac C2D seems to be using an LG/Philips S-IPS panel. SwitchResX reports the info as "LM201W01-SLA3."
It looks like my IMac 20" has TN Display: DDC block report generated by SwitchResX for display Color LCD 0 1 2 3 4 5 6 7 8 9 A B C D E F ----------------------------------------------------- 0 | 00 FF FF FF FF FF FF 00 06 10 6A 9C 01 01 01 01 1 | 00 10 01 03 80 2B 1B 78 0A CF 74 A2 57 4A 9C 25 2 | 11 50 54 00 00 10 01 01 01 01 01 01 01 01 01 01 3 | 01 01 01 01 01 01 7C 2E 90 A0 60 1A 1E 40 30 20 4 | 36 00 B1 0E 11 00 00 1C 00 00 00 01 00 06 10 30 5 | 11 08 00 00 00 00 00 00 0A 20 00 00 00 FE 00 4C 6 | 4D 32 30 31 57 45 33 2D 54 4C 46 31 00 00 00 FC 7 | 00 43 6F 6C 6F 72 20 4C 43 44 0A 20 20 20 00 2B ----------------------------------------------------- Valid DDC block: checksum passed EDID Version........1.3 Manufacturer........APP Product Code........27292 (6A9C) (9C6A) Serial Number.......16843009 Manufactured........Week 0 of year 2006 Max H Size..........43 cm Max V Size..........27 cm Gamma...............2.20 DPMS Supported Features: ------------------------ Display type: ------------- RGB color display Input signal & sync: -------------------- Digital Color info: ------------ Red x = 0.636 Green x = 0.292 Blue x = 0.146 White x = 0.313 Red y = 0.340 Green y = 0.612 Blue y = 0.069 White y = 0.328 Established Timings: -------------------- Manufacturer Reserved Timings: ------------------------------ Unknown timing 3 Standard Timing Identification: ------------------------------- Monitor Description blocks: --------------------------- Descriptor #0 is Timing definition: Mode = 1680 x 1050 @ 60Hz Pixel Clock.............119.00 MHz Non-Interlaced Horizontal Vertical Active..................1680 pixels 1050 lines Front Porch............. 48 pixels 3 lines Sync Width.............. 32 pixels 6 lines Back Porch.............. 80 pixels 21 lines Blanking................ 160 pixels 30 lines Total...................1840 pixels 1080 lines Scan Rate............... 64.67 kHz 59.88 Hz Image Size.............. 433 mm 270 mm Border.................. 0 pixels 0 lines Sync: Digital separate with * Positive vertical polarity * Negative horizontal polarity Descriptor #1 is Manufacturer specific data (not interpreted here) Descriptor #2 is ASCII data: LM201WE3-TLF1 Descriptor #3 is Monitor name: Color LCD
OK, I have an iMac with a cracked LCD, but I don't need the H-IPS. Can I replae it with the cheaper one? If yes, where can I fine it?
