Question about Compaq Presario CQ50-215NR Notebook
Try to see if it is not a issue caused by using a wrong resolution ..In this case if you use one with a small size height ..may cause a black band on the bottom ...so ..open the display settings ...and under the resolution ...choose one by one ...untill you get to one which fits your screen and such ..If this seam not to work ... it may be a corrupted driver..In this case download and reinstall the driver for the video card ..This will fix it if there is something wrong with the driver..If after reinstalling the driver and choosing different resolutions will not make it right again ..you should consider the display being permanently damage d ..and look for a replacement for i t..
to check if it is a display damage ...try to hook up the external monitor ...(secondary monitor ..vga out ) ..Just plug another monitor you may have around in the vga port ..and enable it from the driver ..If that black band appears again ..it means there is nothing wrong with the display ..but it something from the video card ..or operation system ..First try to reinstall it ..and than look for video card replacement ..or in case it is a built in video card ..and can not be replaced..and also has no slot for other card to be installed...you may consider to get a external card on fire-wire or usb ..for to be able to use it proper ..(will be tricky to make the wiring for the monitor ..but will work with an external one .
lets hope it is nothing that serious and will work ..
