Occasional Brief Flicker - CRT Monitor - Dell P990 Trinitron
Recently I've started noticing a monitor 'flicker' that is a brief shrinkage of the screen display on my monitor, perhaps by ~5%. It is hard to define when it happens and exactly describe what happens. It always catches me unawares.
The Dell Ultrascan P990 came with a machine I purchased in 1999, so it has given me good service. My Sapphire Radeon HD 3870 PCIe 512 Mb graphics card came with a machine I had built for me in 2008 (see my specs)
I'm currently running Win7 Pro x64.
Could this flicker be a sign that the CRT or other monitor circuitry is failing?
My son gave me a hand-me-down Samsung S24A450BW LED monitor. I've not switched to it because photo forums I've checked suggest that the CRT monitor should give a superior image.
Can anyone offer any insights?
thanks
