beezow Posted March 8, 2014 Share Posted March 8, 2014 Finally took the plunge and bought a an Asus VG248QE. Loving it so far for the 144Hz, colors are a bit meh especially coming from a 90% gamut screen. One issue I've noticed though is that the LCD does not receive any signal (or at least it says "DisplayPort No Signal" before the Win7 login screen (currently connected via Thunderbolt/mini-DP to DP cable). The entire POST + boot sequence can only be seen on the laptop screen, but not on the external. Did a bit of digging around and apparently this is an inherent feature of the Thunderbolt/mini-DP connection (what???). Anybody have any ideas? I mean the external works fine once the laptop has finished booting, and the signal starts at the Win7 login screen. But it's kinda annoying that I can't tweak any BIOS settings unless I'm on the laptop itself. Quote Link to comment Share on other sites More sharing options...
Slovedon Posted March 9, 2014 Share Posted March 9, 2014 All of my laptops, including my current P150EM, have done this with external monitors, no matter what connection type (HDMI/DP/DVI). Quote Link to comment Share on other sites More sharing options...

beezow Posted March 10, 2014 Author Share Posted March 10, 2014 ^by that, do you mean disconnect the LVDS connector from the mobo so the laptop's LCD no longer works? I guess I could give it a whirl sometime. Quote Link to comment Share on other sites More sharing options...

Disconnected from the motherboard entirely? I'm just referring to the same situation the OP is talking about, with the external monitor connected to the laptop and internal LCD connected normally. I'm not saying it's impossible, but just speaking from my experience, my laptops have always shown the boot process on the LCD screen and then switched to the external monitor at log in.

Moderator BAKED Posted March 10, 2014 Moderator Share Posted March 10, 2014 Is the mini display port routed through the dGPU or iGPU? Quote Link to comment Share on other sites More sharing options...
beezow Posted March 10, 2014 Author Share Posted March 10, 2014 Since I'm running a P370SM, it's through the dGPU as all SLI capable laptops have the iGPU cutoff from the hardware front (unless it has a MUX). Quote Link to comment Share on other sites More sharing options...
