Android HDMI Out - General Topics

Hi My Seniors. Is there any way to adjust android HDMI output to Monitor refresh rate to 90fps or 120hz. I got 165hz monitor , tab s7(120Hz), Red magic (120Hz). But when i connect to monitor, only get maximum 60 Hz. Can someone advise is there any way to change to 90hz or 120hz. Root is no issue for me. or is android limited 60hz HDMI out ? Thanks

It's a imitation of your cable / colorspace.
When connecting to my monitor my Rog3 will output up to 160hz no problem which uses the NV12 color space, however once you connect something like a capture card it will limit to 60hz because it switches to RGB color space.

Auto refresh rate manual over-ride?

Hi all,
I was just wondering if there is a way to force certain apps to run at 120 Hz when my phone is set to the ‘Auto Select’ refresh rate. I have had this on since i bought the phone but the Microsoft Launcher will only run at 60fps unless i force the phone to remain at 120 Hz universally, something i don’t wish to have enabled for battery reasons.
Many thanks!
I got this problem too , 120Hz is not real

App for changing refresh rate (max = 60hz)?

Is there an app for older devices (before the use of 90hz and above in today's phones) that can change the refresh rate from 1hz to 60hz or something like set options like 30hz/45hz/60hz?

Refresh rate, measured in Hertz (Hz), is how quickly a display can refresh an image. Wondering why you want to narrow down phone's default refresh rate?

Main reason is battery saving. I have also read that upcoming (or already released) oppo phones will have adaptive refresh rate ranging from 1hz to 120hz so I was wondering if there's a way to do that in older devices with root?

Screen sizing issue on my monitor

I have a RCA 1080p monitor connected to MSI GTX 550 ti through HDMI. My native and recommended resolution is 1360x768 but when I increase size, it shows image zoomed and too blur. I tried resize screen which made my resolution lower as it thought my monitor is low resolution, but there was a black ribbon on left of monitor. But then main issue is blur content and screen issue. Issue is resolved when I use HDMI on my led but issue remains in monitor. Kindly help me out

Hello, sound's like a driver issue. Whether the graphics card or the monitor isn't recognized with it's correct available resolutions. I would reinstall the drivers.
It sounds like you may be running into a resolution issue. The resolution of 1360x768 is not supported by your MSI GTX 550 ti when connected to an HDMI monitor. The highest resolution supported on a 1080p HDMI monitor is 1920x1080. You can try setting the resolution of your monitor to 1920x1080 in the display settings of your graphics card. This should resolve the blurriness and black ribbon issue. If you are still having trouble, you may need to update your graphics driver to the latest version. If none of these solutions work, you may need to get a new graphics card that supports higher resolutions when connected to an HDMI monitor.

Refresh Rate & Touch Sampling Rate VS FPS

WHAT IS REFRESH RATE?
The number of times the screen refreshes its image each second is measured as the refresh rate. It is determined in Hertz (Hz). Most entry-level smartphones have a 60Hz refresh rate, whereas mid-range smartphones have a 90Hz or 120Hz refresh rate, and premium smartphones have a 120Hz, 144Hz or 165Hz refresh rate. Although most phone brands are introducing adaptive refresh rate it's a brand new feature for smartphones — a device display with an adaptive refresh rate is able to change the refresh rate to match your actions on the screen depending on the range of the Refresh rate e.g a device with 120hz will adaptively switch between 60 - 120Hz. While the frequency at which the display on your phone interprets your input is known as the touch sampling rate (also known as the response rate). In other words, it refers to the quantity of times your touch is registered by the display. The display becomes more sensitive the faster the touch sampling rate is.
By minimising gaps in its interpretation of your touch input, the screen can respond more precisely and provide a smoother experience. Since a delay of a few milliseconds might occasionally mean the difference between winning and losing, this is very helpful for mobile gaming. The Redmagic 7 Series(960Hz), IQOO Neo5 & Realme GT Neo3 150W and other smartphones have the highest touch sampling rate available at the moment, which is 1000Hz. To explain better; Refresh rate refers to how quickly the screen displays the shifting pixels, whereas touch sampling rate refers to how quickly the screen reads your input. The former deals with sensitivity, whereas the latter deals with motion simulation. The animations on the screen seem more fluidly as the refresh rate increases.
A smartphone with 90 Hz refresh rate and 240 - 300 Hz touch sampling rate, in my opinion, is ideal for an all-around experience.
WHAT IS FPS?
Most of the time, people mistake FPS for refresh rate. The quantity of frames displayed on your screen each second is measured in FPS (FRAMES PER SECOND). This always relates to everything you do while watching a movie or playing a game on your screen.
WHICH IS MORE IMPORTANT?
Refresh rate and FPS must be high for a fluid performance when used for gaming. This is due to the visual experience being confined to the weakest connection in the end. The refresh rate of the display must at least match the highest FPS that the GPU is capable of producing in order to operate at peak efficiency. As a consequence, there won't be any delays, clutter, or motion blur during the performance.

Change refresh rate for certain apps

Hello,
I have flashed a custom ROM (LineageOS) for my Motorola Edge 20 Pro phone. The only feature I miss from stock is the ability to set refresh rate for games to 120 or 140hz sometimes, otherwise I like my phone to be at 60hz for power savings. I turn off all animations anyway.
I tried to flash the Moto games apk which did this but sadly I get an error: "Package com.motorola.gamemode requires unavailable shared library moto-core_services; failing!"
I had a look on the play store and I couldn't find much. What options do I have if any?
Thank you
AFAIK a screen's refresh rate ( measured in Hz ) typically is fixed, unless device has a variable refresh rate ( VRR ) feature, e.g. 60-144 Hz.
With the moto app when games are detected it would up the refresh rate automatically.
I can set it to 120hz which is semi variable, if the screen brightness is high enough, but I don't really want 120hz etc for anything apart from games, I'd rather take the extra battery life!
