Because some older Seiki units exposed EDID incorrectly, I considered using a custom EDID override. I downloaded a small EDID utility (there are several community tools) and read forum threads where users exported an EDID from a working monitor and applied it to the TV. That process can force Windows to recognize native resolution/refresh precisely, but it carries risk: a bad EDID can cause display issues or make certain formats inaccessible. I decided against flashing anything permanent for now and instead tried a low-risk method: use a custom-resolution override in my graphics driver rather than changing EDID. Creating a custom 1280x720 profile with exact timing matched what the TV accepted and produced the cleanest result so far.
