I would recommend first measure Vcc-WP resistance - that's because some vendors don't tie WP to Vcc directly, but via some pull-up resistance (to enable, for example, pulldown controlled via some GPIO). In that case it's perfectly sufficient to temporarily bridge WP to Vdd (GND), without any serious soldering/cutting.I haven't done any hardware mods, so if you have a better guide, I can link to it. I saw someone mention connecting the write-protect pin to ground, but I don't know if that's safe. I saw another site mention soldering a resistor: https://www.imsolidstate.com/archives/879 In the case of the ASUS VG248QE, it's possible to disable write protection for DVI by enabling "BURNIN" mode in the service menu (press and hold the menu button down while powering on the monitor, and then press the menu button to open the service menu). On many monitors, the service menu can be enabled by holding down one or two buttons while powering on the monitor. I've also been looking for ways to bypass the GPU because NVIDIA GPUs will not recognize a monitor with a bad EDID. AMD GPUs are fine as you've noticed. Do you know of any USB to I2C devices that can be programmed with C or C++? |
