I did notice variations in my DVI cables, even though they all had the same logo markings. I tried all the way to 1920 by 1080 successfully without Optimum resolution notice (monitor and GPU only can go to 1280 x 1024 max).

Syncmaster B1940 never displays the optimal resolution notice including when you exceed the max resolution of both the monitor and GPU by creating a custom resolution. This model works with all connector configurations, IE: DVI to DVI, VGA to VGA, HDMI to HDMI, And DVI to VGA Adapter and VGA from adapter to monitor. Syncmaster b2030 only displays optimum resolution notice if you exceed the optimum resolution. The OS, GPU, or HDMI cable are not related to this, except for the HDMI cable which must be a special high speed designation for 4K display or will not do 2160p. With a DVI to DVI or VGA to VGA it only reports Optimum Resolution notice if you exceed the optimum resolution.
SYNCMASTER 226BW HZ PC
Syncmaster 2033 has the problem when using a DVI to VGA adapter on the PC and a VGA cable from adapter to monitor, occurring every time you turn monitor on or bring it out of sleep regardless of what the resolution is set at.

This is an issue with all the Syncmaster models newer than b2030. The workaround solution of hitting the Menu or OCR button on the side or bottom right of the monitor for an instant, shuts the Optimum Resolution message off until the next time you turn it on. I found some partial solutions and or workarounds. I have 5 Syncmaster monitors and I have found this issue very troubling with 3 out of 5.
