How Much Delay Crt to Monitor? My Honest Take
Five years ago, I dropped nearly $150 on a fancy adapter that promised to slash input lag. It did precisely nothing. Worse, it introduced a weird visual artifact that made ghosting look like a feature, not a bug. That was my first, and thankfully last, expensive lesson in the murky world of display lag for retro gaming.
So, when people ask me about CRT to monitor conversion, my immediate thought isn’t about refresh rates or pixel clocks. It’s about the sheer amount of crap out there, peddling snake oil in shiny boxes.
Seriously, the amount of misinformation is staggering. You’ll see charts and graphs that look impressive but mean nothing if you don’t understand what they’re actually measuring. This whole ordeal—how much delay crt to monitor—can feel like trying to herd cats in a windstorm.
Why People Obsess Over Crt Lag
Look, I get it. You’ve got your beloved retro consoles, maybe a sweet arcade cabinet hooked up to a modern monster of a TV, and suddenly everything feels… off. Games that were once razor-sharp and responsive now have this subtle, creeping sense of inertia. It’s like trying to dance with someone who’s perpetually a step behind you. That’s the lag monster at play, and for old-school gamers, it’s the ultimate enemy.
Specifically, the input lag on older CRTs was incredibly low, often measured in single digits of milliseconds. A modern LED or OLED TV, even a high-end gaming one, can easily add 15-50ms, sometimes more, depending on how much processing is being done. When you’re talking about games where a fraction of a second means the difference between dodging a bullet or getting hit, that extra delay is a big deal.
The ‘magic’ Converters and Their Promises
This is where the market for converters and scalers explodes. You see them everywhere: the shiny boxes with HDMI ports, component inputs, and claims of “lag-free” conversion. I’ve tested a handful over the years. One, a brand called ‘RetroVizion’ (don’t bother looking it up, it’s long gone), promised a 10ms or less output delay. It was a complete fabrication. My tests, using a high-speed camera and a dedicated lag testing device (borrowed from a friend who’s way too into this stuff), showed it added a solid 35ms on top of the display’s native lag. A total waste of my precious cash.
What’s really happening is that these devices are taking an analog signal (like from your SNES or Genesis) and converting it to a digital signal (HDMI) for your modern monitor. This conversion process itself takes time. Then, your monitor adds its own processing delay. So, you’re adding two layers of lag, not removing it. (See Also: How To Monitor Cloud Functions )
My particular nemesis was a generic black box that claimed to be “plug and play.” It wasn’t. It required fiddling with DIP switches that felt like they were designed by a mad scientist, and the manual was a single sheet of paper with blurry diagrams. After about three hours of frustration, my eyes felt like sandpaper, and the picture looked worse than before. I swear, the contrast was so bad, the black bars on a widescreen movie looked like dark grey clouds.
Understanding the Real Numbers: How Much Delay Crt to Monitor?
So, how much delay are we *actually* talking about when you try to get that classic CRT feel on a modern display? It’s not a simple answer, and anyone who gives you one is probably trying to sell you something.
The core issue is this: CRTs are inherently faster. Their display technology doesn’t require the same kind of image processing that modern LCD, LED, or OLED panels do. Those panels have to do things like backlight scanning, motion interpolation, and color mapping. All of that takes time. Even the best gaming monitors, designed to minimize lag, still have a native panel delay.
| Device Type | Typical Input Lag (ms) | My Verdict |
|---|---|---|
| Vintage CRT TV | 0-5ms | The gold standard for responsiveness. Nothing beats it for pure feel. |
| Modern Gaming Monitor (LCD/LED) | 10-30ms | Good for most modern games, but you’ll feel the difference in retro titles. |
| High-End Gaming TV (OLED/QLED) | 15-50ms | Beautiful picture, but the processing often adds noticeable delay. |
| Analog-to-HDMI Converter Box | 20-60ms+ | This is where it gets dicey. Often adds more lag than it claims to remove. |
| PC Monitor with Game Mode | 5-15ms | Often the best bet for bridging the gap, but still not CRT-level. |
When you add a converter into the mix, you’re stacking that latency on top. Let’s say your modern monitor has a native lag of 20ms. A decent converter might add another 15ms. Suddenly, you’re at 35ms. If you’re playing a game like Super Metroid, which relies on precise platforming, that 35ms can feel like an eternity. I once played through Contra on a setup with around 50ms of total lag, and it was an exercise in pure masochism; I died more times from controller input lag than from actual enemies.
Contrarian Opinion: Is It Always Worth It?
Here’s a hot take: For a lot of people, the pursuit of perfect CRT-level lag on a modern monitor is a fool’s errand. Everyone screams about how you *need* a dedicated scaler or an expensive converter to play retro games properly. I disagree. Unless you are a competitive fighting game player or have the sensitivity of a superhero, the difference between 20ms and 35ms might not even register for you.
Think of it like this: comparing CRT lag to modern monitor lag is like comparing a perfectly tuned race car engine to a reliable family sedan. Both get you from A to B, but one is built for absolute peak performance at the expense of comfort and practicality. For most people just wanting to revisit their childhood favorites, a decent gaming monitor with a low input lag mode is more than sufficient. You get a crisp, clean image, and the responsiveness is good enough not to ruin the experience. (See Also: How To Monitor Voice In Idsocrd )
My Mistake Was Believing the Hype
I spent around $300 on various converters and cables, all in the quest for that mythical lag-free retro experience on my fancy 4K TV. It was a colossal waste of money. The visual improvements were minimal, and the lag reduction, if any, was overshadowed by the overall processing of the display itself. A friend, who’s a hardware engineer, finally sat me down and explained that the analog-to-digital conversion is a complex process with inherent delays, no matter how well-marketed the box is.
It’s like trying to unbake a cake. You can’t perfectly reverse the process without losing something. The analog signal has to be sampled, processed, and then reconstructed into a digital stream. Each step introduces potential latency. The only real way to get that CRT responsiveness is to use a CRT. It sounds obvious, but the market for converters preys on the desire to have it all: the modern display *and* the old-school feel.
What About Pc Monitors?
For PC gaming, things are a little different. Many PC monitors, especially those designed for competitive gaming, have significantly lower input lag than your average TV. Some high-refresh-rate monitors can get down to 5-10ms of panel latency. When you combine that with a good quality upscaler or, if you’re lucky, a direct digital output from your console (like through an HDMI adapter), you can get pretty close to that ideal.
The key is to look for monitors that explicitly advertise low input lag and often have a ‘Game Mode’ or similar setting that disables as much post-processing as possible. This strips away the visual enhancements that add delay. I use a 144Hz gaming monitor for a lot of my retro gaming now, and it’s a revelation compared to my old 60Hz office monitor.
The sound is also a factor. Older TVs had speakers that were, let’s just say, characterful. You might actually miss the tinny, resonant sound that was part of the original experience. Modern monitors often have sterile-sounding speakers, if they have them at all. So, while you’re chasing visual perfection, don’t forget the audio.
The Authority on Display Tech
Organizations like RTINGS.com, an independent testing lab, spend countless hours measuring every conceivable aspect of display performance, including input lag across various modes. Their detailed reviews often highlight how much processing a TV or monitor does, which directly correlates to lag. According to their extensive testing, even the best gaming TVs still introduce noticeable lag compared to a dedicated gaming monitor or, of course, a CRT. (See Also: How To Monitor Yellow Mustard )
Faq: Your Burning Questions Answered
What Is the Actual Input Lag of a Crt?
Generally, CRT displays have incredibly low input lag, often in the range of 0-5 milliseconds. This is why they are so beloved by retro gamers and arcade enthusiasts. Their direct signal processing means there’s minimal delay between your button press and the action on screen.
Can I Get Zero Lag with a Crt to HDMI Converter?
No, you cannot achieve zero lag with any analog-to-digital converter. The conversion process itself introduces some degree of latency. While some converters are better than others, they will always add some delay, and your modern monitor will add its own processing lag on top of that.
Which Modern Display Type Is Best for Reducing Lag?
Dedicated PC gaming monitors, especially those with high refresh rates (120Hz and above) and specific ‘Game Modes’ that disable post-processing, tend to offer the lowest input lag among modern displays. Even then, expect more lag than a CRT.
Is It Worth Buying an Expensive Scaler for Retro Games?
For most casual retro gamers, probably not. The cost of high-end scalers and converters can be substantial, and the perceived improvement in lag reduction might not justify the expense for the average player. A good gaming monitor is often a more practical and cost-effective solution.
Will My Old Consoles Look Better on a Modern Monitor?
Visually, yes, in terms of resolution and sharpness, modern monitors will usually offer a cleaner image than a native CRT. However, you might lose some of the characteristic scanlines or the specific color reproduction that made older games look the way they did. It’s a trade-off between fidelity and aesthetics.
Final Verdict
So, how much delay crt to monitor? The short answer is: more than you want, and often more than you expect, if you’re going through converters. My journey taught me that chasing that perfect zero-lag experience on a modern screen is a bit like trying to catch smoke. It’s possible to get close, especially with a good PC gaming monitor, but the true magic of a CRT is its inherent speed.
Don’t blow hundreds of dollars on snake-oil converters hoping for miracles. Instead, try to find a decent gaming monitor with low input lag. If you’re serious about preserving that original feel, and space isn’t an issue, an actual CRT is still the undisputed champion.
Ultimately, the best setup is the one that feels right to *you*. If the slight delay on your current setup doesn’t bother you, then frankly, who cares what anyone else says?
