Today I finally got around to swap my dim T60 SXGA+ panel for the UXGA panel I bought. I carried out some other small projects when the laptop was opened up anyway, like change the Ultranav pad and buttons, and install a WWAN antenna in the lid. Right after boot up with the new panel, the screen flickered for a split second and went right into *crazy* resolution, ie. 1600 x 1200. And it was bright.. Wow.
To make a little follow up on this thread, I decided to do a before and after comparison. The way I ended up doing this was to actually borrow my wife's Dell Latitude D820 and do a photo session. This is not scientifically correct, and it might not give an exact comparison, but it gives a slight clue about the amazing difference my new UXGA panel made. My wife changed the panel in her Dell (herself..!) a year ago, so hers is still bright, and to be a non-IPS panel, it's a decent panel, with good viewing angles and colors. I don't know what brand it is.
The way I did this experiment, was to put both laptops side by side in a totally dark room, and opened a full screen Notepad window on both. The 3 first pictures are taken before I changed the T60 panel. The T60's BIOS Display setting is High, so this is the brightest it ever got. The camera is in Auto mode, so it adjusts the exposure according to the brightest panel. So the different pictures can not be compared to each other.
Above: Both laptops at full brightness. This shows how much brighter the Dell is at this point.
Above: The T60 is at full brightness, while I adjusted the Dell's brightness down to a level where it matched the T60s. That was level 4 out of 8 on the Dell.
This is the same photo displayed on both laptops, you can clearly see that the T60 panel has a distinct yellow tone compared to the Dell. The Dell is still down to 4/8 here.
The next pictures are taken after I changed the T60 panel.
Above: The Dell is still at level 4, while the T60 is at full brightness. Notice the amazing difference.. Due to the camera in Auto, the Dell screen gets really dim here.
The last picture shows both panels at full blast. The T60 is now brighter than the Dell.
