Custom Resolution Utility (CRU)

[mathiok1]

Hi, I'm new in overvclocking my monitor/tv. I have a 2D HD LG Tv with a native resolution of 1366x768, and I'd like to know how much Hz can I get without crash my TV o something worse. Thank you![/size][/font]

Is there any chance to overclock my old TV samsung UE40es5500w?

hi everyone, i have a few questions i hope i can get answers because i will be very happy if i succeed. My system is notebook but I connect it to the monitor and use it. My main monitor is ASUS VS247 1920x1080 60hz monitor. I use the internal screen of the notebook as the second screen, and it is 144hz. I wanted to watch some youtube videos and increase the hz value of my main monitor, but no matter what I did, it didn't work. For example, I never had the "Automatic LCD Standard" option. I already tried to change the speed from the nvidia resolution change settings, but the result was that the screen went black. Don't worry, I know that the main monitor works with the notebook's external video card, I'm sure of it. can you please help me? can i increase my hz?
System:

Hi Toasty,

I bought a Sonos Arc which I hooked up to my TV's arc hdmi port. From my tests it will not pass through 5.1 audio. The Sonos app shows only Stereo. So I was trying to use CRU to add 5.1 to the EDID, but so far without success.

I don't even know whether what I'm trying to do is possible.

My tv is a Panasonic TC-P50VT25. I just bought a mini pc to go on the back - it's a Beelink SEI 12 - an Intel device running Windows 11.

Any advice would be much appreciated.

Many thanks.

Hi Toasty, and all community.
Thank you for your work and efforts.

I got new ThinkPad T14s intel (21BR00DURA - Intel i7-1260P with Intel Iris Xe Graphics) with a BOE display panel. The laptop is awesome.

The big problem is that my eyes are highly sensitive to displays with 60hz (I have a headache and some dizziness from 60hz).

I tried to set any refresh rate higher than 60hz in CRU but after applying the new refresh rate in advanced settings display got black for 10-15 settings and reverted to the original 60hz.



Please help, how is it possible to increase the refresh rate on ThinkPad T14s intel?

However in windows with CRU I can only increase the pixel clock up 216MHz. Anything higher than this, the refresh rate doesn’t show for me in Windows.

Is there anyway for me to raise the pixelclock to 286.5 using Windows?

216 MHz is the limit for 4-lane DisplayPort in Reduced Bit Rate (RBR) mode with 8 bpc color, so you're probably getting 6 bpc color in Linux, which would allow up to 288 MHz. You'll have to change the color depth to 6 bpc using your GPU's control panel.

Thank you Toasty for the help. Looks like the only option for my display in my GPU control panel is 8 bpc color. But now i know the reason why I could get a higher pixel clock in Linux than Windows.

Really appreciate you taking your time to help me out.

How can 60 Hz on an LCD panel possibly cause headaches and dizziness? If you want a higher refresh rate laptop, get a higher refresh rate laptop.

Did you configure the speakers for 5.1 in the Windows sound control panel?

What exactly did you try? What refresh rates did you try? How is the monitor connected?

1. I recommend adjusting the release notes to indicate there are latency benefits for certain laggy-buffering displays like certain OLED and DLPs. It also even reduces non-strobed LCD latency too with certain sync technologies, especially if you're using Scanline Sync with the tearline adjusted to near bottom of VBI so it's a "end-of-VBI Present()" replacing VSYNC ON's "beginning-of-VBI Present()".

2. I recommend renaming "Vertical Total Calculator" to "Vertical Total Calculator (QFT)" to make sure QFT is part of it. Ideally it should have said "Quick Frame Transport" because it is universal, not just for strobing, but I'd settle for just appending "(QFT)" to make sure users get that assocation. Instead of something obscure like "Vertical Total Calculator".

Searching Google, "Quick Frame Transport" is widely the dominant name for this, especially outside engineer circles, with the most Google search results, and it would be good to keep it in sync with existing Internet information.

Update!

One fantastic thing about ToastyX' new "Vertical Total Calculator (QFT)" feature is that it's a method of creating custom fixed-Hz modes for a VRR panel from a non-VRR GPU (e.g. older GPUs, Intel GPUs, etc)

For example, for a 120Hz VRR display, ToastyX can create a 96Hz fixed-Hz mode that looks exactly like a permanent 96fps framerate cap on a 120Hz FreeSync VRR signal.

The topology of both signals is actually identical, and the display will usually sync to a fixed-Hz signal created via Vertical Total Calculator on the working VRRmax.

It's almost like an EDID-based frame rate cap on a VRR signal -- except it's a fixed-Hz signal that can work from any non-VRR GPU. Quite useful for special applications, like connecting laptops and HTPCs to some VRR TVs.

Instructions.

1. Enable VRR setting on your television.
2. Make sure a picture is displayed at max Hz
3. Use ToastyX to create the non-VRR fixed-Hz mode
......Start from your working max-Hz mode.
......Select the setting "Vertical Total Calculator (QFT)"
......Modify the refresh rate to any refresh rate within the VRR range of your TV
......Save and test!

This will usually work (even on non-VRR GPUs, such as Intel), provided the television is correctly VESA Adaptive Sync (resizeable back porch, the same method as Vertical Total Calculator), allowing you to do custom fixed-Hz refresh rates on your TV where it would otherwise never support! The topology of a fixed-Hz QFT signal is surprisingly similar to a perfectly framerate-capped VRR signal. Most scalers/tcons treat this fine, which is also a major scientific explanation why QFT more often successfully works on VRR-compatible panels!

Several useful purposes: Useful for 48fps HFR videos, 50fps emulator, 100fps emulator, 57.1Hz arcade, 96fps double-strobe BFI simulating 35mm projector, nonstandard software frame rates, synchronization with virtual reality mirroring (e.g. 90fps 90Hz chromecast-style mirroring from headset to TV) etc.

Several hundred of fans (through different channels) absolutely adore the new Vertical Total Calculator. One of us achieved a 13ms latency reduction on a non-strobed display. Thank you!

Zodios is correct.

Many of us have the problem, which is part of why Blur Busters exists, from the motion blur headaches of sample-and-hold 60Hz.

Many of us have motion blur headaches from the motion blur of 60Hz.

It's not all about flicker, but also from motion blur and/or sensitivity to 60Hz stutter (on OLED, 60Hz can still "stutter", since stutter is directly tied to flicker fusion threshold.
- Sensitivity to display motion blur; and/or
- Sensitivity to stutter of 60Hz

Remember, stutter and persistence blur is exactly the same thing (sample and hold effect) -- see variable speed animation demo http://www.testufo.com/eyetracking#speed=-1 and stare the 2nd UFO for at least 30 seconds.

View the 2nd UFO of this TestUFO animation for 30 seconds on both 120Hz+ LCD and 120Hz+ OLED
- On LCD, the stutter blends to blur at about 50fps
- On OLED, the stutter blends to blur at about 75fps.

Scientifically it is the same principle as a vibrating music string.
Slow music string = visibly vibrates
Fast music string = blends to blur

Same for edge-flicker of low frame rate stutter stutter.
Slow sample and hold = visible stutter (edge flicker)
Fast sample and hold = blends to blur (edge blur)

Slow GtG pixel response will soften stutter, adjusting the framerate threshold where stutter blends to blur. Once GtG is zeroed out, your regular-stutter-blends-to-blur threshold is roughly equal to your flicker fusion threshold.

Regardless of whether your headache/nausea/eyestrain/motionsickness (or all) is caused by stutter or blur, 60Hz is a major ergonomic problem for SOME of us.
