The topic of I switched from HDMI to DisplayPort and fixed PC gaming bottlenecks I didn’t… is currently the subject of lively debate — readers and analysts are keeping a close eye on developments.
This is taking place in a dynamic environment: companies’ decisions and competitors’ reactions can quickly change the picture.
Bottlenecks in PC gaming don’t always occur due to the CPU, GPU, or even the software. Some overlooked elements, such as the cable connecting to the monitor or the display output port, rarely enter the conversation because they are thought to “just work.” That assumption doesn’t really go very far if you are trying to get the most out of your setup.
for example, I spent a long time optimizing my PC for performance, and at one point, I was convinced that there was nothing more that I could do. However, a switch from HDMI to DisplayPort made me see the bottlenecks I didn’t know I had.
There’s a good reason why HDMI dominates in most setups. Monitors and GPUs support it without any friction, and most importantly, nothing about it feels broken. However, the problem is that the “good enough” part of this interface hides the limitations in plain sight.
On paper, my gaming monitor has support for a 180 Hz refresh rate and adaptive sync. However, things were not lining up the way they should. For instance, I was limited to a lower refresh rate, and a quick look at the specs showed that my external display has an HDMI 2.0 port, which maxes out at 144 Hz in 1440p.
Moreover, the variable refresh rate wasn’t working with the HDMI connection. That’s basically where the switch made its impact. I found out that my monitor has a DisplayPort 1.4 port, which allowed the panel to reach the 180 Hz refresh rate. VRR was also working as it should.
VRR allows for a display to adapt to inconsistent frame rates, making it important for gaming.
Newer standards like HDMI 2.1 address many of these limitations on paper, including higher bandwidth and proper VRR support. The catch is that gaming monitors implementing this updated standard tend to be on the premium side. DisplayPort 1.4, on the other hand, has been around for a while now and is widely available across mid-range models.
The LG Ultragear 27GR83Q-B is a QHD gaming monitor with a 240 Hz IPS panel, HDMI 2.1 and DP 1.4 ports, and AMD FreeSync Premium.
In my case, with DisplayPort 1.4, I was able to get a better gaming experience without needing to upgrade my hardware.
While I was able to unlock the full features of my gaming monitor with DisplayPort, it’s not just about specs. Desktop PCs come with a wide range of ports, and modern GPUs support both HDMI and DisplayPort. The case for laptops and mobile devices, however, is different.
Most come with a limited port selection, with many defaulting to a few USB-C ports. To connect an external display to such devices, you would need to rely on a Type-C port with DP Alt Mode. It’s possible to use a USB-C-to-HDMI cable or adapter, but this requires an active converter.
That is, the cable or adapter needs to translate the incoming DisplayPort signal from the USB-C port to HDMI, done through a dedicated chip. This translation can add latency, which matters for competitive gaming. USB-C to DisplayPort, on the other hand, happens without any conversion, preserving full bandwidth and introducing no additional latency.
DisplayPort also brings a key advantage for multi-monitor setups. It comes with features like daisy-chaining, which can be handy for setups where cable clutter needs to be kept to a minimum.
Although DisplayPort may seem like a clear winner, especially for low-end and mid-range monitors, it’s not the right choice for every setup. HDMI can still make more sense in some scenarios. for example, when the gaming PC is connected to a TV instead of a monitor.
Modern TVs don’t really come with a DisplayPort port, and using a DisplayPort to HDMI adapter doesn’t make sense. There’s also the matter of support from the source device. If, for instance, the PC maxes out at DisplayPort 1.2, but has an HDMI 2.0 port, the latter would be a better pick.
Moreover, with newer HDMI standards, such as HDMI 2.2, the gap in terms of bandwidth and feature support has narrowed. So, while I have benefited from the switch, the same won’t stay true for everyone.
