I haven't tried the VGA port yet, since I would like to run it digitally, but I can try it tonight. I can run it a 1280x1024 with no issues at 60Hz, and if I switch to 75Hz it does the same thing, on and off. It doesn't stay on for more than 7 or 8 seconds. When I changed the settings to 1680x1050, the screen goes black for a few seconds and then comes back on for a short bit, then goes off again, etc.
I hooked up using a DVI-HDMI adapter and a DVI cable to the HDMI output on the laptop. I have just purchased an HP DV4-1465 and hooked up an Acer P221w monitor. I am hoping there is something similair with the Intel GMA 4500MHD that I am just missing so far.
#DOES INTEL GMA X4500 SUPPORT DUAL MONITORS DRIVERS#
When I had a similar problem with my previous laptop that had the ATI Mobility Fire GL, I had a similair problem which took ages to resolve but it ended up being one of the 'panning' settings on the video drivers which ended up allowing the higher resolution. I have also tried Ultramonand still can't find a way to get the preferred setup. I'veinstalled the latest monitor drivers which don't help and uninstalled and reinstalled the latest video drivers which didn't help. My optimal setup is 1920 x 1200 on the monitor as the primary and 1280 x 800 on the laptop display as the secondary. The max resolution I can get on the monitor is 1280 x 1024 (native resolution is 1920 x 1200) and the max resolution I can get on the laptop is 1680 x 1050 (native resolution is 1280 x 800 which isn't even an option from the Intel drivers). I've got the HP 6730b laptop and a 24"external monitor (HP w2408h) connected via VGA.I'm trying to runin the extended desktop configuration with the monitor as the primary and the laptop as the secondary. I'd also like to know the answer to this question.
