hello, just recieved my L90D+, and here are the results of a comparison with the Sony 21" E500 CRT that it is replacing.
When I unpacked it I plugged it into my laptop (rage mobility soemthing or other) to look for dead pixels. 1 present, wouldn't massage back to life.
Checked it against the banding jpeg from the post above: yes I could see the banding.
Changed to 16 bit (still on laptop): horrific banding - if you are seeing banding this bad you have set up something wrong!
Moved it to the PC (ATI X800 Pro), plugged it straight into the DVI output with the Sony still on the VGA output: a little bit of banding., big improvement over the laptop.
BUT I can see banding on the CRT too!
Switched to 16 bit, same results on both CRT and TFT: very ugly.
back to 32-bit, install the Hyudai drivers (as opposed to plug and play) and the color profile. To do this I have to change to multi monitor, eg the TFT as monitor 1, and the : hmm banding., worse than before, but still no where near 16 bit ugliness.
I tired to roll back the drivers, but now XP and the catalyst drivers are playing tricks, and don't agree with each others settings!
So at the moment my opinion on banding is:
it's dependent on settings for your settings and drivers for both the monitor and graphics cards. SOme people will percieve it more than others. It is present on good quality CRT's if the settings are right (or should that be wrong?)
If you are into digital photography, you may have seen many comments about the right screen 'temperature'. Most people have their screens set incorrectly, too bright being the common fault. Photographers tend to set their screen for 5000K (degrees Kelvin), Videographers often use 6500K, and gamers use the standard (CRT) setting of 9300k (equivalent to flourescent lights). At 9300K the banding in that gradient should be visible on a CRT.
At this time I have no idea how to set the temperature of my TFT, but this
link indicates that the cd/sq m is the measure to use. 110 for photos, maybe 200 for gaming. The L90D+ is capable of 300 apparently: compare this to 80 or 100 cd/sq.m of a CRT.
