However, I sent without realizing my story left out key points. The click sounds like it normally does when being awakened from sleep mode, except distinctly *louder*. And, I use this CRT with many different video cards, none of which that I can remember switch *loudly* like the rv516 *sometimes* does: mga400, i810, i845, i865, i915, i945, iG31, iG43, nv r11, nv r84, rv200, rv250, rv370, rv380, Cedar, XGI Z7/Z9 & others. The rv516's loud switches are accompanied by a very brief flash of bright white only at the top of the screen. My other cards don't cause that. -- "The wise are known for their understanding, and pleasant words are persuasive." Proverbs 16:21 (New Living Translation) Team OS/2 ** Reg.
