Will using custom resolution utility work for me?

cns00 · 08 Apr 2023

My laptop screen is 60 hz. I connected my laptop to my tv by using an hdmi cable. My tv is Sony Bravia kdl-43w660f and its refresh rate is 60 hz.

I discovered a program called custom resolution utility and you can use it to overclock the refresh rate of your screens. I want to overclock my refresh rate from 60 hz to 75 hz. I ran the program. https://i.imgur.com/8dxc0sR.jpg is what I see for the laptop screen and https://i.imgur.com/hKXPCvs.jpg is what I see for the tv. What should I do next?

I think I have to click the add under detailed resolution and I create a new line which is 1920 x 1080 75 hz and then I move that line to the top and I have to do that for both the laptop screen and the tv. Am I correct?

After that I have to close the program and I run restart.exe and restart64.exe to restart the graphics driver or I can restart the pc.

I have some concerns and they are:-

1) If I set both the laptop screen and the tv to 75 hz then will I actually get 75 hz on the tv? Is there any way I can convert 60 hz refresh rate to 120hz? - Quora says that you can't change the refresh rate of the tv from 60 hz to 120 hz because the tv panel is 60 hz so I am unsure if the tv can get overclocked to 75 hz.

2) I am worried that things can screw up and I get a black screen. How do I undo the changes that I did if I have problems? I run reset-all.exe while the laptop is in safe mode and I delete the new rows that I created and then I delete the program and then I restart the laptop?

3) Will my games run ok on 75 hz and the graphics won't get distorted? Some games only support 60 fps and I will be running them on 75 fps.

4) My laptop has an Intel graphics card and an Nvidia graphics card. Will overclocking the refresh rate happen under the Intel graphics card or under the Nvidia graphics card? If it happens under the Intel graphics card then can I run games on 75 fps on the Nvidia graphics card?

I would never monkey around with the refresh rate. It's just fictitious and has the potential to mess things up but good. How do you restore? Use the program then uninstall the program.

The Specs say 30,50,60 Hz

So, no support for anything higher.
EDID info should be sent back from the TV thus you will not have the choice of anything higher.

This EDID info is so that you cannot set your graphics to some odd frequency or resolution that it cannot display.

Your image I assume just shows the spec in the top panel and in the lower panel a couple of ones within the possible range. Not detailed by Sony but they are in the allowable range.

I have 2 Sony TVs so I know. All are still 60 Hz.

It is a pointless increase anyway, and you might damage/lock up the TV.

Ok thanks. Thus you can easily overclock laptop screens and external monitors but overclocking tvs is risky?

I have been gaming for 20 years+ on 60 fps. People are telling me that gaming on 120 fps is awesome because 120 fps is smoother than 60 fps. That's why I am considering overclocking from 60 hz to 75 hz.

However, I am not sure that this is necessary. Please see What Is A Good FPS For Gaming? [2023 Answer] - GPU Mag. It says 120 fps is needed if you played fast paced games and multiplayer games. Also it says that if you play slow paced single player games then 60 fps is perfect and the game already runs smoothly on 60 fps. I play single player games which are action\turn based jrpg games, 2d scrolling games and point and click adventure games on 60 fps and it is already smooth and I don't know if extra smoothness is needed. What do you think?

It is not overclocking, it is operating out of the specified range of the screen.
Just to repeat, it is pointless increase anyway.

Did you know the European or UK TV format for PAL was some 25 frames? Here in th U.S. for the old NTSC it was 30 (29.97). You know why? Because your eye can't tell the difference...

Sure, anything at 60 and above in a video game makes things smoother, but your monitor has to support it...

You can't overclock a display over its threshold, as others pointed out your monitor only goes up to 60hz.

You are also basically asking the difference between hz and FPS, is that they are directly in relation to each other. hz is how fast the display can be updated so the faster the better and FPS is how many frames that your GPU can process and store while it waits for the display to catch up and update the image on the screen.

in both metrics depending on game the faster the better so if you are playing a competitive fighting game for example then a high unlocked frame rate and high refresh rate is good because essentially you are trying to receive visual information faster than your opponents and in many cases it can lead to winning games you'd be surprised because lots of games are frame based with things like animations especially fighting games.

Many games don't require optimal latency so you can just lock the FPS to the monitors refresh rate for optimal image quality and lower the stress on the GPU and monitor and computer in general at the same time.

Also you don't need to use external software to overclock a monitor you can do this natively inside windows in the advanced display settings should you ever need to do this in the future and your GPU control panel can also do it.

Take this example

Around 0:56 timestamp as the forum is not excepting timestamp. Sorry cleaned up this post a bit to be more coherent as i was a bit sleepy before but now have a second wind.

60hz is refreshing the monitor 60 times a second in turn 120hz is 120 times a second and so on.

Look at the guns muzzle flash clearly the 240hz gun flash starts before all the rest of them so that player is essentially receiving visual information faster and is able to make input decisions quicker based off his visual perception.
if these were people fighting he is slightly ahead of the curve with an advantage and can win games because of this advantage.

This also means 240hz player also potentially knows they shot their gun and also their opponent before the rest of the players even realize.

240hz's muzzle flash diminishes first and then the rest go in order from bottom to top that is because as the refresh rate gets faster the lower refresh rates are literally not getting that same information because it halves the slower the refresh rate gets almost like simulated dropping frames in sense because they only really get half the information and it halves each time the lower it gets.

You cannot discern that you are playing a game at 60hz vs 120hz unless you test it by playing both those refresh rates what i mean is that you don't know that you are losing information like Unconscious incompetence of understanding. This goes for anyone because we only see and process what is in front of us but if we look at side by side comparison then we can see the difference.
Four stages of competence - Wikipedia

Players on high refresh rates do notice the smoothness though and that is literally because they are receiving more information of the image and faster.

Frame time is also important because its the metric that tells you if you are sending the frames at the speed of you monitors refresh rate so

1/60 x 1000 = 16.6ms or 60hz
1/144 x 1000 = 6.9ms or 144hz.

etc.

Thus as I said it depends on the games that you play. If you play fast paced games and multiplayer games then high refresh rate is useful because the game is smoother and the input latency is less so you can react faster.

If however you play slow paced games like a jrpg that has a lot of dialogue and no fast response is needed on 60 fps and the game already is quite smooth and nice then I think that there is no point in playing the game on a higher refresh rate screen. The game could be more smoother but you gain nothing from it. Also playing games on 60 fps is ok because a lot of games only support 60 fps. You should play a game on a higher refresh rate only if you benefit from it.

Anyway, please go to Singleplayer games at 120 fps or at 60 fps but better visuals? :: Hardware and Operating Systems and see what Schrute_Farms_B&B said. He said "but one have to keep in mind that 60FPS on a 60hz monitor feel completely different than 60FPS on a 100/120/144/240hz monitor. Therefore its really hard to make a final judgement. Ive recently played on a 60hz panel and it felt more like 30-40FPS on a 144hz display."

What did he mean by completely different when he said 60FPS on a 60hz monitor feel completely different than 60FPS on a 100/120/144/240hz monitor? Is 60 fps on a 60 hz screen nicer and smoother than 60 fps on a higher refresh rate screen? Also why did he say that using 60 hz feels like 30 to 40 fps on a 144 hz screen? 30 to 40 fps can look choppy. 60 fps is less choppy and it's smoother.

Basically they are just saying the discrepancy between refresh rates and frame time because they understand how it works i think.

60 FPS on a 144hz monitor would be 60 fps over 6.9ms you are getting those 60 frames faster than a 60hz monitor but its still only 60 frames which means information loss still that also means you are not just halving the information displayed once you are halving it twice when your monitor can update three times faster than that.

I don't understand. Please explain it better. Is 60 fps on a 60 hz screen better or worse than 60 fps on a higher refresh rate screen?
