For comparison purposes, we ran a combination of CheckScreen and DisplayMate on the Samsung 763MB 17” CDT against the previously reviewed Samsung 955DF CDT. Below is a table with the tests performed and notes we made during testing. Our test machine is composed of an Inno3D GeForce4 4200 using the VGA 15 Pin D-sub cable. We ran all of the tests at 1280x1024 pixels with a refresh rate of 65Hz. Before the final benchmark, we calibrated the monitor as per the instructions included with DisplayMate; any changes to the CDT during the initial calibration run are noted in the observations.

Overall, the only disappointment we had was the amount of glare on the CDT. Compared to the other monitors in the lab, the Samsung 763MB had the most contrast by far. Of course, remember that the flat surface of the 763MB makes it most optimal for direct reflection. Also, since the driving force behind the MagicBright technology is the 330cd/m2 luminance rating, we believe that Samsung cut down on some of their anti-glare coatings. Anti-glare coatings dim the maximum brightness of the monitor considerably.
Another thing we noticed about the CDT was the slight ghosting. Unfortunately, the OEM cable on the monitor was not replaceable. The 955DF that we reviewed several months ago also had this problem. Hopefully, during the next revision of the Samsung CDT, they will implement this change. For the most part, most of the tests produced similar results as the successor to the MagicBright, the DynaFlat.
We were very impressed with the geometric linearity and screen regulation of the CDT. We can directly associate this with the true flatness of the MagicBright tube. Since the screen does not bubble or curve in any direction, the screen image itself is completely unwarped.
