hi, Im having a problem when i connect my laptop with external display. My laptop is HP tx2(12" display) with windows vista sp2 and my external display is an LCD tv of Onida(Xaria 22") When i connect my laptop to the LCD tv, the connection is ok... display comes properly....resolution is also good... but after some time of using it(either watching videos or even normal browsing) the display flickers and then gets diconnected(with the disconnection sound or tone) and automatically gets connected again. sometimes after auto re-connection the resolution also gets changed....this is really annoying.. Iv used the help section... they asked me to increase the flicker rate to atleast 75 but my laptop has a max freq of 60hz only. iv also applied max resolution to the screen...but the same thing always happens again.. then i also connected the same lcd tv to my another laptop(hp dv6000, 15.4", vista sp2) and the same problem never comes. even the flicker rate of that laptop is max 60 hz. both have same resolutions also iv tried all that i cud.... advise please.....
