Recommendations for new monitor
- Edited
tfouto @Lauda89
a) TV's can have their own issues with image quality when attempting to use them as a computer monitor (i.e subpixel layout, also chroma subsampling that's used to "fit" more data into a connection of fixed bandwidth)
b) If the only thing different is the components of the computer were changed, while otherwise running the same software I highly doubt changing monitors will do anything to "solve" the issue.
TrantaLocked i think, for the most of us the problem is in the LED backlit. Monitors/TV's which uses LED backlit are more agressive on eyes/brain!
Well since no one here was actually helpful, I ended up rolling the dice with an omen 25i. Decent enough for gaming, and the polarization is horizontal and works decent enough for my eyes. No splitting head ache and can look at it for a decent amount of time. Could there be better monitors out there… perhaps but this was enough for my use case.
Lauda89 Another update: I tried the samsung G8 OLED with the 7900X and with the 1660super but the situation is still the same: dizziness.
Desperate, I decided to change the 7900X and motherboard with a 13700K. Because i can use the Accenture PC with W11 21H2 + i5 1145G7 with the uperfect 17" portable monitor and my old CCFL.
So i changed the MB, the CPU, installed W11 21H2 but nothing change, still sick with every monitor i got.
The iGPU is different to be precise because the 13700K has a UHD 770 while the 1145G7 has the Xe. Maybe this is the reason but I am beginning to think that the motherboard plays a very important role.
The old perfect PC (1700X+RX 480) I "destroyed" it two weeks ago by updating the motherboard bios for the purpose of changing the CPU. Putting the old bios back didn't fix the problem.

Lauda89 NVRAM values. Disconnect the power and pull the CMOS battery connector out and leave it off for an hour to give it a good long time to discharge. When you reconnect it, all the contents will have been blanked and it will load the values in again from the chip that is present. You will know it has happened because you will need to set the time and date again. If there is no connector, then just remove the battery itself, usually a CR2032 coin cell or similar.
The reason this is worth trying is because downgrading doesn't necessarily overwrite a value if it has no reason to if a value is present.
Sunspark Don't know about the motherboard he has, but I'm aware of certain motherboards that store user configuration and other variables in nonvolatile storage and use the lack of power as a cue to potentially clear it, rather than the "old" practice of storing the config in RAM or similarly power backed storage that would be blanked upon removing all power. What is the difference? I've seen evidence the former isn't entirely perfect due to potential firmware bugs.
Practically, not much difference, but flashing a new bios by itself does not reset/clear settings. Manually pressing reset-to-defaults may work, but that is dependent on an understanding of how the function works. What is it doing? Is it just writing in values it knows about and is visible in the user interface, or does it blank the whole thing? The fact that it doesn't reset the clock indicates to me that it doesn't blank everything and maybe it's accessing values that a different bios version set in the memory. So, if he's complaining about his computer being "different" despite a downgrade, there is value in clearing the bios nvram by removing the battery. I've done it plenty of times on my NUC, there is no risk on a modern system, this isn't a glitchy network router from 15 years ago.
Sunspark I wasn't implying a risk, more so the fact modern BIOS's operate using nonvolatile storage that's usually shared with the flashed image and attempting a "reset" by removing the battery does not necessarily guarantee all nonvolatile storage is cleared as a result.
If you want to go further into this you can use an external programmer to read out and manipulate the BIOS flash out of band.
I hadn't considered that he might have a motherboard that doesn't clear any settings at all even without the cmos battery present.
Thankfully mine isn't one of those.
Thanks, guys for the replies!
I have an ASUS crosshair vi hero, there is a specific bottom on the back to do a CMOS but it didn't fix the problem.
Today i want to try to remove the battery and let see if it works.
I didn't think the motherboard bios was related to our problems. I am beginning to think that the image rendering is not the real problem.
Lauda89 With the battery method the time is reset but still dizziness. Well i fucked up my old system, now i know to not upgrade the BIOS for the future.

I can give you a summary:
OLD system:
1700X + RX480 + Alienware monitor was good until W10 1909/2004.
New system november:
7900X + RX480 bad with eveythings i tried:
Old W10, W11, alienware monitor AW2518HF and BENQ CCFL V2400W monitor.
7900X + 1660 Super the same.
7900X + 970 the same.
So i decide to buy an intel CPU and try to use it with the BENQ CCFL monitor like i am doing with the accenture notebook: dell latitude 7420 intel 1145G7 xe ipgu.
New system march:
13700K + 970 + W11 21H2 (like the latitude 7420) is bad with the alienware, BENQ CCFL and also with the portable monitor UPERFECT 17". Maybe the UHD 770 do something different then the Xe igpu or maybe is the motherborard and its bios the problem?! I don't know.
So not a great idea, other 800€ to the bin. I will try the LG OLED monitor 27GR95QE as soon as it will be available in Italy.

JTL Also, are we sure that we can talk about good monitor and bad monitor?
I mean, I have been using the BENQ CCFL since 2006 so I would call it a good monitor but with the two new PCs it becomes a bad monitor (and also with the latitude if I update W11 to the latest updates).
Even the alienware, it was a good monitor with the setup I had but connected to a MAC it was always bad.
What if the monitor has nothing to do with our problem? I mean the type of panel, backlight, refresh rate etc... maybe it is just the signal coming to the monitor that makes it a good monitor or a bad monitor the problem is this signal seems to be impacted by 1000 factors.
