Hey, everyone, I'm still relatively new to the tech-interest field, but I'm doing my best to gain knowledge while not annoying people too much with stupid questions, so please, bare with me. Monitor issue: I have a Samsung SyncMaster PX2370 LED monitor. However, my computer's display refuses to fill the entire monitor. There is a black border around my computer display which appears between where the display ends and the edge of the physical screen. I'm sure there is some simple solution to fixing this, but if anyone can give any advice, I'd really appreciate it. Video Card upgrade question: My pc runs two ATI Radeon HD 4850 video cards. If I wish to upgrade the graphics, can I switch out one at a time for newer, better cards, or do I have to change both at the same time? I just purchased an XFX ATI Radeon HD 5770 card. Can I swap out just one of the cards for the new card and wait to replace the other until I can afford it, or should I just wait until I can afford another one and then replace them both? Also, if my pc opperates these dual graphics cards, will it be problematic if I run different graphics cards (i.e. one 4800 series, one 5700)? Or will there even be a visible difference? Again, any help would be greatly appreciated. Thanks so much.
