I use a 39″ 4K monitor for my computer display because I appreciate a large work surface. Meanwhile, I also like to step away from my desk and use Chrome Remote Desktop on a small 14″ Chromebook to continue my work on the road. So I find myself frequently flipping resolutions, which on Windows 10 is not a simple one-click operation. What I really wanted was the ability to switch resolutions with a single keystroke, and AutoHotkey came to the rescue!

ATEM Television Studio Pro HD has all of the same features but the switcher is fully integrated into a professional control panel so you can work much faster on larger complex live productions. The new ATEM Television Studio 4K model now adds Ultra HD and 12G-SDI technology for HD and Ultra HD formats up to 2160p60. HVS-490 switcher inherits key technology of HVS-2000 and HVS-390HS while opening the door to even more affordable 4K production. Exclusive MELite™ technology extends the switcher’s 2 M/Es to offer 6 M/E performance.1 Expand your switching capabilities even more by assigning FLEXaKEY™ or feature rich 2.5D DVE, for compositing with up to. However it does not allow learner to switch the resolution of videos. Currently we are uploading 240p, 360p resolution videos. How can we implement the resolution switcher.

AutoHotkey is an open-source tool for Windows that allows you to automate tasks through text scripts, and map them to any Windows key (as well as joystick and mouse events). The following script maps CTRL‑6 through CTRL‑9 to different screen resolutions (and refresh rates). To use the script, install AutoHotkey, save the following script to a file with an “.ahk” extension, and then double-click the file. It will execute the script (with an icon in the system tray that you can use to shut it off). You can add the .ahk file to your Startup folder if you want the script to automatically start when you boot:

To customize this script, you can change the hot keys (“^6” for example means CTRL‑6), and change the different resolutions. The parameters to ChangeResolution are:

  • color_depth — The number of bits per pixel for color (leave at 32 for most purposes)
  • width — width of the screen in pixels
  • height — height of the screen in pixels
  • refresh rate — the screen frequency (typically 60Hz, but for some monitors like the Seiki, the 4K resolution is at 30Hz)

Uctox help. I hope this helps you save time!

Our newest production switcher, leveraging the creative power of the HANABI series.

HVS-490 switcher inherits key technology of HVS-2000 and HVS-390HS while opening the door to even more affordable 4K production. Exclusive MELite™ technology extends the switcher’s 2 M/Es to offer 6 M/E performance.*1 Expand your switching capabilities even more by assigning FLEXaKEY™ or feature rich 2.5D DVE, for compositing with up to 12 keyers. Take advantage of this truly broad range of switching in live production.

  • 1 Using an optional HVS-49IO card. In 4K mode, 1 M/E + 1 MELite is available.

HVS-490 Introduction


Switch Resolution Output

MELite expands the capabilities of AUX transitions. With an AUX bus, able to preview transitions before executing them, and enjoy the same control over AUX output as for PGM or PST. Two MELites are provided, and an optional HVS-49IO card brings the total to four. Assigning FLEXaKEY to an MELite expands the system adding the equivalent of two M/E buses to the standard two Full ME’s, brings the total available to four. 4–6 M/E performance is possible in a 2 M/E switcher.

  • Preview output from an AUX bus when applying transitions (cut, mix, or wipe) or keying. This background breaking technology makes sure your production is ready for virtually any request.
  • For greater impact and more sophisticated switching, MELite can be assigned before M/E buses.
  • Any ME can be assigned to multiple on stage monitors for independent background transitions and graphics transitions all from the same control panel.


Special FLEXaKEY keyers are designed for flexible reassignment. The four FLEXaKEYs provided operate separately from standard keyers of the full M/E buses. Easy keying of four different FLEXaKEYs in any AUX bus is another highlight enabling impressive performances beyond the reach of conventional switchers.

  • Quad FLEXaKEY system can be freely assigned to M/E or AUX buses. Combine up to eight keyers for an M/E bus (4 keyers + 4 FLEXaKEYs).
  • P-in-P display is possible using an AUX bus, and assigning FLEXaKEY to an MELite enables use as an upstream key.
  • FLEXaKEY can also be applied to create a multi-monitor video wall with a single HVS-490.


Choose from cut, mix, or wipe transitions. In addition to 100 wipe patterns, the switcher offers 16 useful 2.5D DVE wipes such as rotate, perspective and reposition. Also rich effects including mosaic, posterization, pseudo color and defocus are also provided.

Extensive input/output

16 video inputs are provided, expandable to 40, along with 9 video outputs (including 1 HDMI port) that are expandable to 22 (including 2 HDMI ports). For 4K*2, 8 to 10 inputs and 6 to 7 (including 2 HDMI ports) outputs (expandable to 7) are provided. See “Options” for details on expansion cards.

  • 2 HVS-49IO and HVS-49EXP4K are required for supporting 4K.

Standard multi viewer output

Resolution Switcher Software

HVS-490 provides three displays of multi viewer output, each supporting up to 16-split display. More than 10 screen layouts each are available. This provides an optimal monitoring environment for both the main operator and other users. 4K output is supported via HDMI 2.0 Level B. Via HDMI outputs, monitor four images on one screen. Using 3 multi viewer outputs and PGM output, up to 49 windows are displayed.

Switch Screen Resolution

AES digital audio I/O (optional*3)

Supports 4 AES (8 channels) of balanced or unbalanced audio input and output. Able to demultiplex AES audio from video/clip input and multiplex AES audio into video output. Use an internal sampling rate converter to sync audio input to the system.

  • 3 With HVS-49AES expansion card

2SI/SQD 4K mode (optional*4)

Ready for 1080/59.94p/50p/29.97p/25p formats, the switcher processes 4K video from the quad 3G-SDI output of 4K cameras in 2SI (2-sample interleave) or SQD (square division) format.

  • 4 With HVS-49EXP4K software and HVS-49IO card

Example of 4K system configuration

The HVS-490 was designed with future 4K upgrading in mind. By adding optional expansion cards provides up to 10 4K inputs and 7 outputs. What’s more, unique use of AUX buses enables a 4K switcher to have the equivalent of 1–1.5 M/E features.

Live staging


Resolution Switcher App

The HVS-490 has an incredibly powerful feature set making it ideal for live staging and event applications where systems must be set up quickly and temporarily. Event memory and macro functions make it easier to prepare for performances. MELite eliminates the need to have several switchers ready for multi-monitor staging, greatly reducing the equipment required. It’s essential to keep production simple and easy, preventing mistakes and helping operators focus on staging.

Mobile OB and Up-Link production trucks

The HVS-490 with its robust feature set is perfect for small mobile video production or Up-Link in which space is limited. The HVS-490 switcher offers a rich feature set perfect for live or recorded production. With integrated frame synchronizers and multi viewer, the HVS-490 can reduce the amount of equipment required in the truck. Using multiple control FOR-A control panels, the system can also provide an environment for several operators each in charge of separate tasks for example one for the main event and a second for a web cut of the same event.
