ASUS VE248H (Black Level Settings Permanent? EEPROM?))
Posted: 30 Sep 2017, 17:27
I got a VE248H which is a fantastic monitor for a standard LCD monitor, probably best standard 24" I ever had. (It does NOT have the dreaded ghosting. Monitor was made in August 2012)
However, it has a *minor* issue, that is that the black levels have a slight hue towards brownish regardless of the standard RGB settings. Now I found that using tools for DDC/CI like SoftMCCS or EasyMCC, in addition for standard RGB gain etc. the monitor also exposes Red, Green, Blue "Video Black Level" settings which is *exactly* what I need. A quick tweak there, and the blacks are PERFECT.
Unfortunately, these settings are not in the OSD of the monitor, and they are not kept when I set them via a DDC/CI tool, the black level settings always reset to 50,50,50 when the monitor is off or when the display mode changes.
Obviously I also checked the service menu of this monitor, and there too are settings for
RGB gain, and RGB offset.
Whereas RGB gain is, well, exactly that and the "offset" as I understand it would be exactly what I need, since this would be the bias/black level for this monitor.
However, changing any of these values in the service menu DOES NOTHING. I don't see any change in the RGB levels of the display whatsoever when I change either a gain value or a offset value, say Green Gain from 112 to 20, I don't see any change in the display.
Anyone an idea why?
What other way would be to somehow change black level settings and make them permanent?
(Can the EEPROM of this monitor be programmed in software? Maybe this would be some way)
