Question about ViewSonic VA1912wb Monitor
Starting a few days ago, I noticed that my monitor was flickering when dark colors were displayed. I reseated the HDMI and power cables, but the only solution I found was to increase the brightness of the monitor to 100%. This is very hard on the eyes (I'm used to about 70%). Does anyone have other suggestions? The monitor was purchased in 2005, but I wouldn't expect it to fail already.
Try monitor menu select Memory Recall and press that, should clear right up

I also had flickering (except at full brightness) even after changing the capacitors. Finally treated the various connectors with silicone oil, and all was fixed.

I just finished repairing 2 of these monitors. There are 4 capacitors (CapXon brand, cheap) on the backlight power supply board that are going bad and are probably bulging and leaking already. This monitor isn't terribly hard to get apart, and somebody with basic soldering skills can do the repair in a few hours for around $5 in parts from DigiKey.
I used replacement capacitors from DigiKey (Panasonic FM brand/model). I replaced ALL capacitors on the power supply board because it is clear the ViewSonic uses bottom barrel parts.
If you don't repair the problem, at some point in the future the monitors won't power up at all unless you power cycle for 20 minutes, then eventually, not at all.

Afraid that doesn't solve the problem; I recently got this problem as well - flickering occurs when dark colors are present. Sometimes I don't get the flickering at all after start up, other times such as now I do.
I've also found that changing the refresh rate depends greatly on what resolution you are running. only 1024x768 can achieve a higher refresh rate. Anything higher than that resolution and it seems, at least for this monitor, you can only operate at 60 Hertz

Go to your Windows display settings and hit the Advance button and try changing the refresh rate on the monitor.
See if that helps.
