Hey everyone, I am new to the forums and I have an issue with my current mac and monitor. I own the following: Macbook - Processor: 2/16 GHz Intel Core 2 Duo - Memory: 2 GB 667 MHz DDR2 SDRAM - Graphics Card: GMA 950 Monitor - Brand New - Samsung SyncMaster 2253lw - Online Retailer said it was Windows/Mac compatible - Startup disc with drivers is windows only, dont know if I need any of that I hooked everything up and used the mini-dvi to dvi connector, and it works grand. The problem I have is that I can only I use my laptop monitor and the display in dual mode to have my samsung run at full 1680x1050 resolution. If I mirror it, (my goal is to not use the LCD on the macbook) the Samsung runs only at my macs highest end of graphics which is 1280x800. I would appreciate any help from someone that could help me finish my setup or let me know anything I am doing wrong. I just want to use my external Samsung monitor as my screen and have the resolution be max for the monitor. Thanks!
