that IS the highest setting, with the PSP plugged in.Viewtiful Darkness said:That really isn't a fair comparison. The only way you can get full brightness on the PSP is to use the AC adapter to plug it into an outlet. When you use the battery only, no matter if it is fully charged or not, you wont' ever get the full brightness. PSP is designed to get full brightness only when you use the AC adapter and plug it into an outlet. It would have been more fair to compare the PSP's full brightness while it was plugged up with the AC adapter to the Nintendo DS Lite's highest brightness setting. The PSP screen would most likely be brighter.
