Windows 7: Laptop performing noticeably worse on own screen vs monitor

Laptop performing noticeably worse on own screen vs monitor

So I've seen this thing lately with my Acer laptop. There's difference between plugging in another monitor or using the laptop screen. Every game I play (mostly CS GO, Dota 2) also runs much more smoothly if I use an external monitor; we're talking about 30-50fps on laptop screen compared to 60-90 fps with another monitor, for example LG W2442PE. I know it sounds silly, but is there anything wrong with the laptop (e.g. drivers, software, even hardware)? Is there anything I could do about it?

Sounds to me like it's using the HD Graphics 4000 rather than the 730M when connecting to a monitor. Also is the Laptop and the monitor you are using both 1920x1080?

On a side note I'd look in to cleaning some of that "Drive 1 Size 385.8 GB Free 29.2 GB" at some point

Yes, they are both 1920x1080. So your point is that in normal mode, the 730M is in use? Isn't the gfx card more powerful than the integrated graphics and should perform better on paper than?

Yes. Indeed the 730M is more powerful than the integrated one but it's probably just a matter of going through some settings and manually selecting with GPU to use on which output.

I can't help you in this case as i'm not sure what you'd be looking at but it should be pretty straight forward. If not then Google is your friend

This might not be any help at all, but then again, it might be..

Anyway, in my PC's UEFI BIOS (might be possible on whatever your laptop has, I think some old CMOS machines have it), there's an option called Primary Graphics Adapter (or something similar), try changing this option.

As I said, this may not help you, because it could be a completely different issue, but its worth a look.

Good luck.

Nice find but completely useless as the laptop uses Dual GPU configs, it's called hybrid GPUs and Nvidia have a driver called optimus that deals with the task of switching between them, you have to (like taylorig has mentioned) go to the Nvidia control panel and choose which GPU to run the external monitor on, specifically, I can't tell you the exact setting because I don't have a Notebook with dual GPUs on to test but it shouldn't be that difficult to find.
