There are several threads on this now that should get consolodated into to
one FAQ:
Depending on the monitor the highlight of the selected cells in Excell 2007
can be very light. There are a couple of easy options to try to address this
(short of MS adding a user option to adjust the highlight percentage):
1) Try adjusting the contrast of your monitor - either up or down. I have a
desktop monitor with a laptop docking station so have a 2-monitor setup. With
the Excel window on the desktop monitor I could barely see the selected cells
but when I dragged the window to the laptop the highlight was fine. The
contrast on the monitor was in the 70-80% range and when I adjusted it to
40-50% the highlight was much more visible.
2) If adjusting the monitor doesn't work you can try changing the window
background color. Right click on the desktop and select properties. Click on
the appearance tab. Click on advanced (oooh...). Select window from the item
drop down list. Click on color one and click on other... at the bottom. On
the upper right drag the black triangle down until you see the color box
darken a little, I adjusted from Red=Green=Blue=255 to 230 for my original
monitor settings. The downside of this is the background can look pretty
dingy - especially if you then adjust the contrast down.
1) is preferred if it works.
