My assumption was just based on the (poor) visual performances and the "Unknown" tag (shown on the System Info) that I mistakenly associated to the graphic card. I didn't think that the display could have been a factor on the performances but, as you say, the system couldn't identify the exact model of the monitor then probably the troubles are coming from there. So you're right, "[RS690M] Wrong monitor identified in EDID" is a more accurate description.
