VRR - Variable refresh rate tj. varijabilno osvježenje je sinkronizacije FPS-a unutar igre sa frekvencijom osvježavanja monitora u realnom vremenu.

FreeSync je AMD-ova VRR tehnologija, koja je besplatna.

G-Sync je Nvidijina VRR tehnologija, koja je skuplja zbog njihovog hardverskog modula kojeg naplacuju monitor vendorima.




G-Sync vs. FreeSync: Adaptive sync gaming monitors explained https://www.pcworld.com/article/2974...er-smooth.html



Nvidija je od 1/2019-te omogucila rad AMD FreeSync monitora na Nvidia GPU karticama od GTX 1000 serije na dalje (i novijim RTX naravno) koji su do tad (do kraja 2018-te godine) radili samo / jedino / iskljucivo na AMD karticama.

AMD nije radio/zahtjevao QC (Quality Check) od proizvođaca monitora u kojima se ugrađivao njihov besplatni FreeSync, te neki su FS monitori imali problema sa prikazom slike u pokretu i treperenjem ekrana.

Nvdija je u svom labosu sa svojom opremom i svojom metodom/kriterijima testiranja, testirala mnoge AMD FreeSync monitore.

AMD FreeSync monitori koji su zadovoljili Nvidijine kriterije, preko noci preimenovani su tj. "postali" su: G-Sync Compatible monitori.

Nvidija je doslovno AMD-u preotela FreeSnyc ime/brending ovim potezom.

G-SYNC Compatible je Nvidijina potrda / žig / certifikat sa kojim Nvidija garantira da je neki AMD FreeSync monitor kvalitetan i da s njim nece biti problema pri VRR-u u u bilo kojim uvjetima.

G-SYNC Compatible testing validates that the monitor does not show blanking, pulsing, flickering, ghosting or other artifacts during VRR gaming.

They also validate that the monitor can operate in VRR at any game frame rate by supporting a VRR range of at least 2.4:1 (e.g. 60Hz-144Hz), and offer the gamer a seamless experience by enabling VRR by default.

What is G Sync compatible mean?

G-Sync Compatible monitors are non-G-Sync displays that support the adaptive sync standard for variable refresh rates while gaming—AMD FreeSync monitors, essentially.
Only models that meet Nvidia's stringent standards achieve the label, and have variable refresh rates automatically unlocked on GeForce GPUs.

Monitor koji nema "G-Sync Compatible" certifikat - validaciju ne znaci da je loš i da na njemu ne radi G-Sync/FreeSync ili da on prikazuje nepoželjne osobine pri VRR-u ali to također ni ne znaci da je dobar.

To znaci da nije zadovoljio Nvidijine kriterije.

Koji su to kriteriji Nvidija nije javno obznanila.

Clanak iz 5/2019 doduše nije ažuriran al svejedno daje sliku o Nvidijinom svrstavanju ali ne i nacinu testiranja monitora: https://www.pcworld.com/article/3398...heres-why.html

Ok kako cu onda znati dal je monitor dobar ?

G-SYNC Compatible Vs Native G-SYNC – What’s The Difference? https://www.displayninja.com/g-sync-...native-g-sync/


Znaci imamo 4 vrste monitora:

G-Sync
G-Sync Compatible (valideted- testirani) = Amd FreeSync + Nvidia
G-Sync non validated (nije još testiran ili nije zadovoljio Nvidijine kriterije)
Obican monitor od 60Hz bez adaptivne sinkronozacije.

koje Nvidija ovako definira u svom Control Panelu: (sliku sam sklepao u paint da vizalno predocim o cemu pricam)



Zapravo ima još 2 tj 6 ukpuno .

Trebao bi naci to na netu i dodati na gornju sliku kad uhvatim vremena.

G-SYNC Ultimate monitors are those that NVIDIA rates as offering “the best experience” when it comes to image quality, color accuracy, variable refresh rate performance and High Dynamic Range with over 1000 nits of brightness

i

FreeSync 2 compared to FreeSnyc has three additional characteristics: High Dynamic Range, Low Framerate Compensation, and Low Latency.

What are FreeSync and FreeSync 2? How are They Different?
https://www.benq.com/en-au/knowledge...freesync2.html

FreeSync (G-Sync Compatible) and HDR work fine, but FreeSync 2 HDR doesn't work on NVIDIA cards. It's a specific feature that requires monitor and game support, as well as an AMD GPU (since it's proprietary, like HDMI FreeSync). You can test this by loading, e.g. Assassin's Creed Odyssey and seeing that FreeSync 2 HDR cannot be enabled.

You can still use FreeSync 2 HDR monitors with NVIDIA and use FreeSync + HDR, but you just won't get the specific low-latency tone mapping feature that is FreeSync 2 HDR.

https://www.reddit.com/r/nvidia/comm...dr_nvidia_gpu/

Q: So if i can get variable refreshrate and im able to avtivate HDR with Nvidia, what advantages would i get from an AMD card running full Freesync2?

A: In general you loose some freesync2 extensions which effect HDR, but they are very very minor. Like auto switching between HDR and SDR (what you do manually), low latency HDR processing blabla. Most of it im pretty sure is just marketing to buy AMD rather than Nvidia...

Razlika između AOC-a 24" i 27" GU2

AOC 24G2U vs AOC 27G2U 6/2020

https://www.tftcentral.co.uk/reviews....htm#aoc_24g2u



Na slici ispod crvenom sam bojom oznacio ono najbitnije na što treba obratiti pažnju te ispod slike napisao komentar vezano za taj oznaceni crveni dio:



Primjetit ce te da 24" model ima visoku minimalu svjetlinu koja se ne može smanjit, dok se na 27" svjetlina može daleko više smanjit.

24-inch version has an annoyingly high minimum brightness, so we don't recommend it for use in the dark - the nearly 90 nits we measure then are too bright for pleasant use.
The 27-inch version can dim significantly further.

https://be.hardware.info/artikel/966...lers-conclusie

27" model ima brži pixel response time (niže vrijednosti G2G tranzicija) tj manje vremena mu treba da pixel promjeni boju, 10 ms u odnosu na 13.8 ms za 24" model

Koliko znam jedino tftcentral.co.uk , rtings.com i YT:Hardware Unboxed imaju specijalan hardwer i softver koji to automatski odradi i detaljno analizira cjeli spektar tranzicija G2G.


Oba rade na 144Hz (refresh rate window) koji iznosi 6.9 ms tj 1000ms/144Hz = 6.9ms

Novi frejm svakih 6.9ms


27" model ima i više obavljenih trazicija piksela 86.7% naspram 80% za 24" model u vremenu refreša monitora pri gorespomenutih 6,9ms.

Upravo zbog toga 27" model ima Nvidijinu potrdu / žig / certifikat da je G-Sync Kompatibilan.


Dok je 24" model koji je za nijansu , neznatno, zanemarivo lošiji toga nema.

24'' mode ima G-Sync (non validated) i radi na G-Force grafickama kao i FreeSync na AMD karticama.

Na 24" modelu radit ce Nvidijina adaptivna sinkronizacija tj zapravo FreeSync , jedino što na njemu nece pisat G-Sync Compatible.

Although the combination of the Full HD resolution and the larger diagonal is not ideal in terms of sharpness, the 27-inch version offers the best experience in our opinion: the negatives are less disturbing and the larger size is great for gaming. (... tj brži.)

GtG versus MPRT: Frequently Asked Questions About Pixel Response On Displays

https://blurbusters.com/gtg-versus-m...ixel-response/

GtG / G2G represents how long it takes for a pixel to change between two colors.

Nisam oznacio crveno ali G2G varira od brzine osvježavanja i postavki overdrajva koju podesimo unutar izbornika monitora.

Pod tablicom Gaming Performanse navedena je optimalna postavka Overdrajva ovisno o frekvenciji osvježavanja monitora te je izmjereno vrijeme G2G tranzicije pri tome.
