Hello all. I am new to this forum so I apologise if my question seems vague. My setup: PE4L with a Gigabyte NVIDIA GTX650 2GB DDR5 PCI-E Graphics Card Lenovo T420 with default system BIOS Intel® core i5-2520M 2.5GHz 6gb ram NO dedicated graphics, but internal is Intel HD Graphics 3000 Windows 7 ultimate 64bit. [h=1]ASUS VE247H 24 inch LED Widescreen Full HD 1080p[/h] My egpu has been functioning from the very beginning, and for games it performs very well. However, if I am watching 1080p videos on youtube or downloaded movies, for example, there eventually comes a point where the entire playback becomes choppy and laggy. Also, all browsers seem to run quite slowly as well, even when switching to low ram usage browsers like opera. Even if I close all other applications the laptop really struggles. However, on my laptop LCD this does not seem to be a problem, only on my external monitor does this lag seem to occur. I have been looking into the 1.x set ups but I am not sure if this is what I need. I tried to disable the igpu through device manager however that didn't seem to work as when I rebooted the laptop, my external monitor was not detected, and the resolution on my laptop was off. I also read somewhere that somebody experiencing similar problems changed the express card speed to generation 1, which I have tried to no improvement. Anyway, if anyone has some tips or suggestions on what I can try please let me know. Thanks!
