Hi

I decided to open another topic and to start discussion from the beginning. 

I am having some problems to choose a monitor for MSFS.

I had a lot of statements and it is getting really confused until now. HDR, HRR, VRR, G-Sync, G-Sync adapt, G-Sync compatible... and endless discussions which makes this process very confusing...

 

First, the specs and the needs:

1. I have i9-10900K with Asus ROG Strix RTX 3090 OC 24GB

2. I would like to run MSFS in a 2K resolution (2560x1440).

 

I would like to know if the following options are good for MSFS, and if not, why:

https://www.asus.com/Displays-Desktops/Monitors/TUF-Gaming/TUF-GAMING-VG27AQ1A/

https://www.asus.com/Displays-Desktops/Monitors/TUF-Gaming/TUF-Gaming-VG27AQL1A/

https://www.asus.com/Displays-Desktops/Monitors/TUF-Gaming/TUF-Gaming-VG27AQ/

https://www.amazon.com/LG-27GL850-B-Ultragear-Compatible-Monitor/dp/B07TD94TQF

 

I would like to keep it simple, like a "yes/no" answer and a short answer if the opinion is negative, and just for these four monitors, not for BenQ, AOC or other personal preferences. Those ones are not expensive at this moment so I should try to buy one of them if they can do the right function. I am trying to choose something and if I keep discussions for 3 months, it is impossible to buy something.

 

Thanks for all the other inputs.

 While they are all not bad, they are all simply G-Sync compatible which means that effectively G-Sync won't work below the lowest refresh rate of the monitor which with these monitors is 48-50hz (meaning that you essentially need to maintain a minimum of 48-50fps in the sim for G-Sync to work). Personally, I wouldn't get any of them as I don't think I could go back to a non G-Sync display.

 You have built yourself a very kick-word not allowed pc, don't skimp now on the display.

What means "G-Sync won't work"? I am still trying to understand this issue...

However, I have another one that I was looking for. It is the MSI Optix MAG274QRF-QD 27" LED IPS WQHD 165Hz G-Sync Compatible. This one goes from 30 to 165 Hz. 

I don't understand how it works but if you mean that the first number (30, 40 or 48) has to start on 1 (something like 1-120 Hz or 1-165 Hz)  then I will not find any monitor except the expensive ones... 

Is this MSI monitor a better solution? It costs around 450 euros...

NOTE:

After writing this post I was looking for NVidia list, concerning G-Sync Ultimate, G-Sync and G-Sync compatible. If I stick to Asus, LG and MSI, 2K monitors are quite few and very expensive... So, with the first number starting on 1, being Asus/LG/MSI (or even Acer), being 2K, and being not so expensive and also being available in my country, this choice seems to be almost impossible. So, I have to try the best solution from all the others...

If it's a true G-Sync monitor (which means it has the nVidia G-Sync chip and not a third-party emulation in the display's firmware), it can sync the frame rate all the way down to 1 Hz...the "compatible" monitors can sync the display only if the frame rate remains above the lowest hardware refresh rate supported by the LCD panel (usually 30 fps).  The beauty of a true G-Sync display with a sim is the ability to avoid stuttering when the frame rate drops below that base panel refresh rate.

And yes, you'll find that the true G-Sync displays are somewhat more expensive.

I already understood... It will come in some time because I already spent a lot of money in the computer. Maximum budget for monitor at the moment is 400-450 euros. 😞

By the way, even if I would like to have a true G-Sync monitor, I cannot find any of them in my country, at least the ones from the NVidia list (Asus, LG, MSI or even Acer).

 

But one question that I still didn't understand: 

Suppose If I go to the MSI monitor which RR from 30 to 165 Hz, the minimum I can go except for the ones starting from 1 like 1-120 Hz or 1-165 Hz. 

If I fly between 30 a 60 fps, I understood that nothing special will happen.

So, what happens if I fly around London or New York and frames are going down, let's say between 20 and 30? The monitor stops? I get tearing? I get stutters? Something different?

Generally you'll start to see some stuttering when the frame rate drops below the min sync rate.

But how is possible to see stuttering with for example 28 frames when I don't see any stuttering with FSX and 23 frames with my actual specs?

Just to understand the process...

 

Now I really get more confused... Activated range (48-165) and Signal Frequency (30-165)...

NOTE:

It is very strange all the G-Sync monitors mentioned in https://www.nvidia.com/en-us/geforce/products/g-sync-monitors/specs/ don't exist at all or are unavailable... I just see some variations like Asus VG27AQ instead of Asus PG27AQ.

Assuming you use VSync to prevent screen tearing, in FSX there are stutters when the frame rate drops below the VSync frequency.  In FSX, if you use full-screen mode and VSync, the frame rate will drop to the next integer-quotient value (e.g. with a 60Hz hardware refresh rate, VSync will lock at 60-30-20-15-12-10 fps (60 divided by 1-2-3-4-5).  So if you produce frames at 35 fps, VSync locks at 30...at 28 it locks at 20, at 18 it locks at 15 etc.  Without VSync, the screen will be partially refreshed with whatever video buffer data has been rendered each refresh cycle, so having a frame rate - refresh rate mismatch won't cause stutters, but will cause screen tearing with panning or other motion.

Complicated to understand for now... I will read more about it. Someone explained that those monitors can work with "multiples". I don't know how to make those calculations but it should not be very difficult.

Anyway I will have to solve the issue, concerning that I will not have a monitor with refresh rate starting at 1... They are not available in my country except one or two which are really expensive.
