15KHZ CRT Monitor: Complete Method Of Uses

If you are seeking 15KHZ CRT Monitor, then you are in the right spot because, in this article, we will learn everything about the 15khz CRT Monitor. 

Using a source that generates 15 kHz natively is the simplest and safest approach to output a 15 kHz signal to a CRT monitor.

 Higher resolutions have now supplanted this format, which was commonly utilized by computers, arcade systems, and video game consoles. Fortunately, connecting your current PC to a CRT monitor is still possible.

How to Use 15KHZ CRT Monitor

240p refers to a frequency of 15 kHz. The Power-on Self-Test is a function that occurs before your operating system starts loading. 

Hyperspin was kept from crashing by using ridiculously broad resolutions. You can use the 15KHZ on the CRT monitor by following the below-mentioned procedures:


The first step is to set your PC’s output to a frequency of 15 kHz. This can be done using either hardware or software, or a combination of both.

On the Windows platform, some strategies have been tried. Although we are certain that they will function with various operating systems, your mileage may vary. The best alternatives are Windows XP or Windows 7.


The most straightforward method is to utilize an ArcadeVGA, a purpose-built GPU that is limited to 15 kHz unless the 25 kHz multi-frequency monitor option is enabled. It’s safe to use from POST2 to gaming, and it’s the best plug-and-play option.

ATOM-15 plus CRT Emudriver:

Another option is to use an older AMD/ATI GPU with CRT Emudriver, a customized version of the Catalyst software (formerly AMD Radeon Software Crimson) that supports magic resolutions3 and super resolutions4 while remaining under the 15 kHz restriction.

You can use ATOM-15 to flash your GPU in addition to CRT Emudriver to heed the warning above.

It’s a modified BIOS firmware that allows you to choose which video modes the GPU can display. Depending on your CRT monitor, you may cap the output at 15, 25, or 31 kHz and POST as if you were using an ArcadeVGA card.

Control Panel for NVIDIA:

If you have an NVIDIA GPU, you may force the output to 15 kHz using the NVIDIA Control Panel. To do so, go to the linked displays list and add a Custom Resolution to your CRT monitor.


Your GPU must be connected to your CRT monitor after it has reached 15 kHz. There are various options for doing so.


You should be able to utilize a VGA to RGBHV BNC connection if your CRT display supports RGBHV5. 

These are an atypical and straightforward method of connecting your GPU to a CRT monitor. If your GPU lacks a VGA connector, you may need to utilize a DVI to VGA adapter.

Interface: RGB

Only RGBS6 is supported by many CRT displays. You could use a sync combiner to combine the sync; however, I like to use an RGB interface. 

S-Video (Y/C):

If both your CRT monitor and GPU support S-Video, this is the most straightforward and cost-effective way to connect them. Although the video quality will not be as excellent as RGB, it may be sufficient for many peoples.


If the CRT monitor you’re connecting to your PC is part of a JAMMA-compliant arcade system, you need to purchase a JPAC. It takes a VGA signal and pipes it as if it were coming from a JAMMA board.


What does a 15kHz CRT stand for?

CRT televisions are the oldest kind of televisions to which older consoles were meant to output. Under NTSC or PAL standards, they usually received transmissions with a 15.7kHz scan rate.

Is Inputlag reduced on CRTs?

Considering the nature of the technologies that do not have the capacity to store visual data before display, display lag is exceptionally minimal for older analog cathode ray tube tech.

Is a 4K CRT even feasible?

CRT couldn’t have handled 4k resolution with the technologies of the late 1990s and early 2000s. Despite advancements in display technology since 2006, there are no 4k CRT displays available.


So that’s all we have to say about 15kHz CRT Monitor. If you can’t output 15 kHz, you might be able to use downscaling to connect the PC (or other devices) to the monitor.

We hope that we have mentioned enough in this post for you that you can easily understand everything there is you need to know about the 15 kHz CRT monitor.
