on the blink

In very sad news, my monitor is developing an issue. The right side of my display has this little flicker, identical to what you would expect to see if my refresh rate was say, 60Hz. However, the flicker is only on the ~3 inches to the very right edge of my monitor, and my refresh rate is set at 100Hz. There’s another monitor sitting near there, but it’s powered down and I can’t figure out why else it would be doing it unless it’s on the verge of failing. I guess this is my wakeup call that I need to get the 21″ GDM-F500R FD Trinitron repaired and get this tiny 19″ Dell/Sony Trinitron P991 off my desk as my primary display.
