Hi

A New problem ..... (sigh)

My Dell Monitor u2312HM keeps "blanking On/Off" whenever our LG 47" LED TV is switched on

My PC is connected to the TV via HDMI & Monitor is connected via DVI-D - from the motherboard (no discrete GPU as yet). This problem was not so glaring earlier as it used to blank on/off just once..... Now however it keep's blanking over 10-12 times........ until I either switch off the TV or pull the HDMI cable from my PC.....(it's around 12 days since I connected my PC to TV.

It also stop's once I select the HDMI (PC) output on my TV. However, if we wish to watch just the TV - then the Dell keeps blanking.

Monitor is at 60Hz & 1980 x 1200 & TV is set on Auto (full 1920 x 1080).
Will try connecting my Dell throught the Display port cable tonight

Note: My RIG (listed below is less than 5 weeks young) & everything is brand new (including the Dell).

Thanks

Terry
