Bij GamePC is een review geplaatst van de Mitsubishi 2040u, een 21" monitor gebaseerd op de superplatte DiamondTron NF beeldbuis met een .24mm aperture grille pitch. Hieronder een hap uit de review:
We would have to say the 2040u did not just beat its previous predecessor the 2020u, but it slaughtered it. Having a 240 MHz video clock frequency, the 2040u has a maximum resolution of 2048 x 1536 @ 60 Hz. Compared to Hitachi's 814 having a 300 MHz video clock frequency, the 2040u only has a 60 MHz input difference. However, that 60 MHz difference did not hinder the 2040u's performance as you may think. At every selectable resolution provided by the monitor, we saw a prime example of what every monitor's image quality should look like. Color and text from corner to corner was very good, best we have seen yet. But the fact that the monitor possesses that natural flat CRT makes images look so much better. With any 21" monitor supporting a resolution of 2048 x 1536, its basically not the most logical setting to use. True the 2048 x 1536 resolution setting on the 2040u is very usable in terms of image quality, but squinting at your screen all day long is not the most enjoyable thing to do in the world. So with that said, we consider the sweet spot for the 2040u being something of the neighborhood of 1600 x 1200 @ 85 Hz. Keep in mind that a contributing factor to a monitor's image quality also depends on the video card being used. A video card with a high RAMDAC is a must for high-resolution monitors. Otherwise you won't be doing a monitor like the 2040u justice. In our case we used Elsa's GeForce DDR video card which did its job well on the 2040u. All in all, we must say JOB WELL DONE to Mitsubishi on their 2040u monitor. It should pose a definite threat to Sony's F500R and Hitachi's 814.
