The title may not clarify my request/issue and I may opened in the wrong section. But from my understanding the display outs are directly connected to the Discrete Graphics and cannot be changed.
You can check if the display out ports are directly connected to the Discrete gpu or wired to the MUX switch by just turning it on and off and then see in the nvidia control panel. You can change the MUX switch in the Vantage Software. This means the laptop monitor can be run of the inegrated graphics allowing the optimus technology to be used, or it can be directly connected to the discrete graphics allowing for a performance gain.

A bios mod will not fix this, this is part of the design of the laptop. You can see what ports are connected to the Discrete GPU or the Integrated Graphics. You can see this for yourself, go into the nvidia control panel, and look under the PhysX tab. This means the Discrete GPU is always on when an external display is connected, and all the applications will run on the Discrete GPU. This is with pretty much most gaming laptops. This is because the all of the display out ports (hdmi, type c) is directly wired to the Discrete GPU. The machine is a AMD-NVIDIA configuration and it has Insyde BIOS. Is it possible to mod the BIOS for this case? I would like to get back Optimus functionality too when external display is connected. It looks like a restriction or a misbehaviour. It is not clear why but this is not a hardware failure cause I have two of this machine and both acts the same with any displays via any connectors. It should behave like when no external monitor. That means that the integrated GPU utilised by default for most non resource hungry processes and if a heavy application starts the system will fire up the discrete GPU.īut Optimus fails when an external monitor is connected and it force to use only the discrete GPU for basically any applications which makes no sense. The machine acts normal when no external display connected and the system utilise the predefined GPU for the applications when needed. Optimus "handles" which GPU should be utilised for a process/application. My machine looks okay on hardware side but Optimus functionality breaks when an internal monitor is connected via any connectors.

Could there be another reason why my brightness gets set at 100%? I have MSI Afterburner, custom refresh rates, and two displays just to name a couple of things that may cause an issue (but didn't cause an issue for the first 5 months).Lenovo IdeaPad Z570 (45CNxxWW). I have the latest drivers, intel drivers, and even the latest bios. I started noticing it after June, I think.
HYBRID MODE LENOVO VANTAGE HOW TO
I do not know how to solve this recent problem. I also hook my laptop up to an additional monitor, but I have done this in the past with this laptop and no problems. This problem is pretty recent, however, and the 60Hz option and adjusting the brightness worked when Hybrid Mode was turned on for the first 5 months of owning this laptop. I created a custom refresh rate of 60Hz which is available as an option when Hybrid Mode is turned off. When checked, the stated refresh rate is 64Hz but it feels like it is at 144hz which is the default refresh rate. The monitor name switches from Generic PnP monitor to Microsoft Basic Display Adapter and says that the refresh rate is at "1.000Hz". Additionally, the battery life doesn't seem to increase. When I turn on Hybrid Mode, I cannot change my brightness whatsoever and the screen gets stuck at 100% brightness.
