Lets discuss why this is the case and find out just how big the difference is in a number of different games.. Most laptops these days have Optimus.. This basically means that the lower powered integrated graphics within the processor are used to send display signal to the screen.. This has the advantage of improving battery life as theyre more efficient and require less power to operate. Contudo, the downside is gaming performance kind of sucks when compared to what AMD and Nvidia have on offer.. These higher powered, discrete graphics options basically sit idle when there are no GPU intensive tasks running on the system.. If you start up a game, Embora, the more powerful discrete graphics will be used to render the frames. Contudo, in an Optimus system, the discrete GPU sends this output via the lower powered integrated graphics., Depending on the game and settings. This can result in a bottleneck situation where the integrated graphics reduces gaming performance.. If your laptop only uses the discrete graphics and doesnt have Optimus like the Aorus 15 or allows you the option of disabling Optimus after a reboot like the Lenovo Y540, em seguida, você, probably not going to see a performance difference with an external screen as youre already bypassing Optimus., This also applies for current laptops that have G Sync, as G Sync requires a direct connection between the screen and Nvidia GPU to work. Many laptops that have display output ports such as HDMI or DisplayPort, have them wired directly to the discrete graphics, meaning that by Running an external monitor connected to one of these well be bypassing the Intel, Integrado, graphics and Optimus as a result.

. This same idea should also apply to AMD Vega integrated graphics.. There will be no difference if the port is connected to the integrated graphics, Embora – and this is why Ive started noting if this is the case in my laptop reviews., To demonstrate this Ive tested the Eluktronics MAX 17 gaming laptop with and without an external monitor, connected.. All testing was done with the same Windows updates, Nvidia drivers and with a 1080p resolution. Literalmente. The only difference is that Ive tested either with the laptops screen so Nvidia RTX 2070 pushing frames via the Intel GPU to the laptops display or with the external screen connected to the laptops, Porta HDMI, which skips the Intel GPU and connects straight to the Nvidia. Rtx. 2070., Its important to note that, when using an external screen, youll still get low FPS if the laptop's screen is in use, because the Intel GPU will still be active. To avoid this either close, the lid of the laptop or most laptops have a shortcut key. You can press to select which display to use so use that, and just pick second screen only. You can also just do this through Windows too. This disables, the laptop screen, without the need to close the lid, which is useful, as some laptops require the lid to be open to cool properly., If youre not sure which GPU is in use, you can simply check The task manager performance tab to see which are active with a graphical load running.

De qualquer forma, with all that out of the way lets get into the gaming benchmarks.. These are the results from red dead redemption 2, which was tested with the games benchmark. Ferramenta. Ive got the laptop screen test shown by the purple, bars the external monitor connected over HDMI in the red bars and Ive tested all setting levels. In this particular title. There wasnt too much of a difference, but the external screen was performing. Better. Battlefield V was tested in campaign mode, and this time there was a bit more of a difference between the two, namely at low settings, where the external screen was 13 faster when compared to just using the laptop screen. And this will be a trend well see throughout most games tested where lower settings see a bigger difference. Shadow of the Tomb Raider was tested with the games built in benchmark, and there was a fair 7 increase to FPS with the highest setting preset. Contudo, lowest settings saw the biggest difference with the external screen. Now almost 21 ahead of the laptop screen. O controle foi testado, walking through the same area of the game in both instances. Há, a smaller 4 higher average FPS at high settings with the external screen. And then this is a little closer to a 5 boost at low. Obrigação. Modern Warfare was tested in campaign mode with either maximum or minimum settings as it doesnt have built in setting presets.. This time there was a larger 11 performance improvement to average FPS.

At max settings a nice difference for such a simple change. Apex legends saw basically no difference at minimum settings, como o 144 FPS frame cap was being hit consistently with this hardware in either setup. Contudo, there was a small 4 improvement to average FPS at max settings.. Borderlands 3 was tested with the games benchmark tool as theres no frame cap in this one were back to seeing larger differences at lower settings. Em configurações muito baixas. The external screen was 25 faster compared to using the laptop screen. Contudo, maxed out there was less than a 3 Aumentar. Fortnite was tested using the replay feature with the exact same replay. File used for all testing. High and epic settings saw small differences, but there were much larger changes at lower settings. Low settings, por exemplo,, Foi 38 faster in average FPS with the external screen. Dota 2 was tested playing in the middle lane and there was a fairly large 20 FPS média mais alta, with the ultra setting preset on the external screen.. The external screen was ahead at all. Definindo níveis, but in this test it seems to do better at the higher settings.. The difference between 1 low in this game was much more minimal. Em comparação. Assassinos, Creed Odyssey was tested using the built in benchmark, and this test saw an 8 higher average FPS with the highest setting preset with a much larger 33 improvement at low settings, onde até mesmo o 1 low with the external screen was close to the average.

From the laptops screen., O Witcher 3 saw pretty minimal differences between the two, but this wasnt surprising as Ive tested this one. In the past, Embora, there was more of a difference at the lower setting levels where frame rates are higher, and presumably, where were more CPU bound. Ghost Recon Breakpoint was tested using the built in benchmark and the results were similar at the higher setting levels where there Was minimal change, no entanto, there was a much bigger differences seen at the lower levels.. A Divisão 2 was also tested using the games benchmark tool and once more, there was a much smaller performance difference with the higher setting presets. While the external screen setup was almost 19 faster at low settings., Ive tested CSGO with the ulletical FPS benchmark., This game saw larger differences compared to the other titles tested.. It seems like the higher your frame rate, the more the Intel integrated graphics is bottlenecked. So for games like this, there are huge gains to be had with an external monitor.. Overwatch was tested in the practice range so, while not quite the same as actual gameplay, it allows me to perform the same test pass more accurately, which is ideal for comparison purposes.. As a game that hits very high frame rates, larger differences were seen between the two tests between low and ultra settings, especially in terms of 1 low performance., Far Cry New Dawn was tested. With the games benchmark tool., There was a fair improvement to both average FPS and 1 low performance with the external screen, with almost a 10 boost to average frame rate at ultra and slightly smaller 9 melhoria para 1 Baixo.

Em média, sobre estes 16 games with the Highest setting preset available, we can see that using an external screen was around 6.6 faster than the laptop screen.. The results, of course vary wildly based on the game and even the specific settings so lets also check out the differences. If we look at minimum settings. With minimum settings, the external screen is now averaging a 16.9 maior taxa média de quadros, so its doing much better compared to max settings. As discussed along the way. This is because the processors integrated graphics seems to become a larger bottleneck as we hit higher frame rates, which is what we typically see at lower settings that are more CPU bound.. A part of it could also be that the iGPU now also doesnt need to waste system resources. Its possible that, for the same reason, we could see less of a difference between laptop and external screen with lower specced machines.. Lower specs would give us lower frame rates. So the bottleneck may be a little less pronounced with lower tier hardware.. I had a quick look at temperatures and didnt see a noteworthy difference in either configuration.. Então, para concluir, if your laptop has Optimus and youre not able to disable it, which is the case for most gaming laptops, Testado ive, you can get a decent performance increase in most games simply by connecting an external monitor.. This is especially true. The lower settings you use, but even higher settings did see a benefit it just wasnt, quite as big.

. Ele vai, claro, depend on the laptop, Embora, if the external display outputs are wired to the Intel graphics, then youre out of luck.. É claro, Im not suggesting you take an external screen with you to get this performance boost. But if you also use your laptop at home, you could easily dock it to an external screen and get a better gaming experience, not only in terms of a larger, melhor, looking screen, but also higher frame rates, as weve seen throughout this testing.. So now that youre, aware of this, is it going to change how you game on your laptop? Let me know if youre going to get or are already using an external monitor down in the comments and, if youre new to the channel consider getting subscribed for future laptop content and tech.
