I use a 17" Samsung Flat CRT monitor.. i use it at 85Hz which is the maximum it can support at 1024*768 resolution that i use.. Since a past few months.. i have noticed that the text appearing on the screen at the edges vibrates vigorously.. The text at the center of the screen is absolutely sharp.. the problem is ony with the edges.. like the start written on the start menu vibrates/shakes as it is located on the bottom edge.. The monitor is 4yrs old... Do i need to change my monitor and get a new one ??? |
when new. Sounds like upgrade time to me. 8)

I had a similar problem with fuzzy text and found it was due to a plug in
p/s for another device. Once I'd relocated the p/s the text was normal.

age of the power supply in the monitor. Generally it's not something that is
worth troubleshooting/fixing. If it gets too annoying it's probably new monitor
time. I've had a couple of Trinitrons do that after running 24/7 for a number of
years. Generally the shake will be worse when the monitor is "cold" and it will
improve a small amount as it reaches normal operating temp.
Electrolytic caps dry out over time...which can cause output ripple to increase.
In turn the increased ripple/ripple current can cause the cap to run even warmer
thus increasing the potential of this failure mode I've noticed that they don't
make CRT's quite as well as they used to. From my experience 4 years seems to be
about the max they last these days. I still have some old 15+ year old Commodore
monitors that still work perfectly to this day. I use them for video/sat receiver
monitors next to my computer desks... Kinda crazy.

It is quite likely that there is a bit more ripple on the driver voltage due to age of the power supply in the monitor. Generally it's not something that is worth troubleshooting/fixing.

great, although is losing some brightness. 'Course, it cost $900 -
one can't expect the same quality for $150 or whatever...

Sounds like beating between 60 Hz power magnetic field and the
85 Hz refresh rate.

The 18* monitors were nowhere near as reliable tho.
