<p class="info-desc">To see a more clean and brighter screen, you have to set the resolution to the optimal resolution supported by the monitor.<br/>
If the monitor screen displays the optimal resolution message, then change the resolution and the vertical frequency to the optimal setting.<br/>
To check the optimal resolution for the monitor, you should check the product manual or the homepage with the product information.<br/>
Generally, if connected to the PC, the optimal resolution is automatically selected.
