You will need to go into.... CONTROL PANEL >> Display >> SETTINGS tab. There you will see a pull down menu to select 1 of 2 monitors. You have to choose to have them both on all the time (multiple monitors) Use IDENTIFY to bring up the display # onscreen. Please accept this answer to remove it from the work queue. :D

HP Compaq 2710p: External monitor does not display anything


Hi, The display properties indicate the hardware is working, so it's likely just a setting. On HP/Compaq models you will see a picture, usually on the F4 key that looks like a screen with two lines beside it. You need to hold down the Fn key(bottom left) and then push the F4 key at the same time to cycle between LCD, external or both. If it is a newer model, a menu will pop up when you do this asking if you want to duplicate the LCD on the external, switch to the external or extend the desktop onto the external. Select the appropriate setting or continue holding down Fn while pressing F4 to cycle between the settings to the one you want. If you have re-installed the computer at some point with anything other than the factory recovery set this may not work and I will have to give you a longer set of instructions. If this works please rate this as fixed, if not reply back and indicate what version of windows you're using and I will post the instructions for the "long" way. Chris

Sounds like one of two things. Either your connection wire from the screen to the hard drive is lose most of the time you can go on the product sites enter the info on the underside of the computer enter that info on the products site and get your info from the help self section or the repair diagram. Number 2 is your screen has a bad wire and it needs to be replace you can find them new on ebay and most of the time it is easy to fix yourself. I hope some of this info helps you.

I have a gotab gtd9-x with jellybean 4.2.2, it's stuck on the system restore page and even when rebooted or turned off, it returns to that same page. Suggestions?


When powering the unit up be sure NOT to press volume Up or Down as this will enable SDK mode (what your currently getting) if your not touching these keys as you power up it may be that the volume key is stuck on in which case it will need looking at by a trained engineer

Tc1100 Blank Screen


You have identified your problem/fault by plugging in an external monitor and the image is OK. This proves the video card is OK and the fault could be the inverter or most likely the CCFL lamp. The flickering screen indicated the CCFL lamp is faulty, it is a mini fluro tube which provides the back-light to the LCD. The inverter supplies high voltage to the CCFL lamp. It could be faulty and it is easier to replace. For service, parts and DIY info check out LCD Parts - use this link to their WEB site : - www.lcdparts.net
