BenQ vs Optoma for Gaming: Input Lag Compared

Input Lag Basics

Input lag is the time between when a frame is sent and when it appears on screen. This delay affects how responsive games feel. Projectors often have more input lag than TVs because they process the signal for scaling, keystone correction, and image enhancement. To minimize this, many projectors include a Game Mode that disables these processes, reducing the delay.

When shopping, look for the projector's input lag specification, usually given in milliseconds. This number varies by model and even by resolution and refresh rate. Generally, lower is better. For fast-paced shooters and fighting games, you want the lowest possible latency. For slower strategy or adventure games, a higher lag is less noticeable. Read our projector input lag guide to understand how to interpret these numbers.

Beyond the projector's processing, the HDMI connection itself can affect response time. The latest HDMI specification, HDMI 2.2, includes features designed to improve gaming, which we will cover next.

HDMI 2.2: Enhanced Gaming Features

The HDMI Forum released the HDMI 2.2 specification, which delivers higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology. More importantly for gamers, it adds enhanced gaming features such as Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM). VRR syncs the projector's refresh rate with the game's frame rate, reducing screen tearing and stuttering. ALLM automatically switches the projector into a low-latency mode when you start a game, saving you from digging through menus. For a deeper look, see our HDMI 2.0 vs 2.1 projectors and VRR gaming on projectors articles.

Not all projectors support HDMI 2.2 yet, but it is becoming more common. When comparing BenQ and Optoma models, check which HDMI version each has. If you play on a modern console or PC, look for at least HDMI 2.0; HDMI 2.2 is ideal for the smoothest experience.

HDR and Gaming: Dolby Vision

High Dynamic Range (HDR) is not just for movies; it enhances games by providing brighter highlights and deeper shadows. Dolby Vision is a specific HDR format that dynamically optimizes picture quality based on your display and the content. According to Dolby, it brings greater brightness, richer color, deeper contrast, and incredible detail. This can make games look more immersive and lifelike.

However, HDR processing can sometimes increase input lag. To mitigate this, some projectors have a game mode that disables HDR or reduces its processing. Check the projector's manual or spec sheet to see if HDR and low latency can work together. For more on HDR, read HDR on projectors and projector HDR formats.

BenQ and Optoma: How to Compare

Both BenQ and Optoma have gaming-oriented lines, but input lag varies from model to model. There is no single brand that is always faster. Instead, you need to compare the spec sheets of individual models. Look for the input lag figure, the HDMI version, and HDR support. Also consider the native resolution: 1080p is sufficient for most gamers, but 4K offers more detail. See our best 1080p projectors and best 4K projectors for top picks.

Beyond gaming features, consider other factors like throw distance, brightness, and smart features. Our dedicated brand guides, best BenQ projectors and best Optoma projectors, provide curated comparisons to help you narrow down your options. Pay close attention to the "Game Mode" setting and whether it works at 60Hz or supports 120Hz if that matters to you.

Connectivity and Industry Standards

A good gaming projector should have the right ports. HDMI is essential, but USB ports are also useful for playing media or updating firmware. The USB Implementers Forum (USB-IF) defines the Universal Serial Bus standard, ensuring compatibility and performance. Check how many USB ports the projector has and whether they support features like power delivery. For a full breakdown, see projector inputs and connectivity.

When comparing projectors from different brands, rely on industry standards. The Consumer Technology Association (CTA) develops standards for consumer electronics, including measurement methods for brightness and resolution. Many manufacturers follow these guidelines, so you can trust the specifications. This is especially important when comparing input lag figures, as there is no single universal test, but CTA-compliant measurements provide a consistent baseline.

What to Pick for Your Use

Questions

Which brand has lower input lag, BenQ or Optoma?

It depends on the specific model. Both brands offer projectors with low input lag, but the exact number can vary widely. Look for the manufacturer's published input lag spec and compare models side by side. HDMI 2.2 support and ALLM make a big difference.

What is Auto Low Latency Mode (ALLM)?

ALLM automatically reduces input lag by disabling unnecessary image processing when it detects gaming content. It is part of the HDMI 2.2 feature set and is designed to give you a smoother, more responsive gaming experience without manual adjustments.

Do I need VRR for a projector?

VRR helps eliminate screen tearing and stutter, especially when frame rates fluctuate. It is beneficial for smooth gameplay, but not all projectors support it. If you play demanding titles on a console or PC, VRR can be a worthwhile feature. See our VRR guide for more.

Can a projector have Dolby Vision?

Yes, some projectors support Dolby Vision, which dynamically adjusts HDR content for better contrast and colors. It is a premium feature, so it adds to the cost. If HDR gaming matters to you, check for this logo on the spec sheet.

What resolution is best for gaming on a projector?

1080p is still the most common for high refresh rates, but 4K offers more detail. The best choice depends on your screen size and viewing distance. For most home setups, 1080p is fine, but 4K gives a sharper image for larger screens.

How do I measure input lag on a projector?

You can use a high-speed camera and a timer, but it's easier to rely on the manufacturer's published figures. There is no standardized test, so compare numbers cautiously. Look for CTA-compliant measurements if available, as they are more consistent across brands.
