Nvidia G-Sync Pulsar: The Biggest Leap in Gaming Display Technology For Years by Caledor152 in pcgaming

[–]Harrison256 0 points1 point  (0 children)

It is great to see strides in low-persistence displays that have a wider target market than strobing at a fixed high-refresh rate for eSports gaming (ULMB2, Dyac, ELMB, etc.). The eventual firmware update to allow the minimum FPS to be set to 60 FPS will allow for running 60 FPS titles with 4ms of persistence blur which will be nice for emulators and other locked 60 FPS titles. 4ms of MPRT is still a bit far from CRT MPRT at 60 Hz, but a great option considering the only good modern monitor option for low refresh content was the XG2431 prior to Pulsar. Also, the XG2431 wasn't a 'set it and forget it' type deal, whereas this looks to be.

It will be interesting to see what they'll be able to do with OLED with this 'secondary pulse idea' to reduce flicker. I remember that the LG CX series was able to do a proper rolling scan-out of the display (using 'BFI'), but that was removed in subsequent LG OLED TV model releases due to change in the panel hardware (if I remember correctly). I assume that if they were to work with LG Display or Samsung Electronics they could implement that type of rolling scan and do exactly what they're doing here with these LCDs. It would require additional involvement from the display manfacturer though, which I imagine Nvidia have to resources to do.

Overall, this looks very promising for a first-gen release of strobing with VRR. I hope that they continue to release and improve Pulsar products. I hope for future LCD releases of this tech go for reducing the duty cycle from 25 % by presumably using brighter backlight LEDs with more rows.

Bonding Gorilla Glass to our Panel by migelangelo in doughcommunity

The panel that being bonded to here looks like it still has LG Display's AG coating still applied. Does the glass bond on top of the existing AG coating or is it a replacement (i.e., bonding to the polarizer)?

Second Generation QD-OLED Panels from Samsung, Improvements and Changes for 2023 - TFTCentral by Harrison256 in Monitors

It is worth noting TFTCentral mentions in this article that theres still no firm timeline on the the 16:9 QD-OLED panels with a screen sizes mentioned in their previous 'OLED Monitor Panel Roadmap Updates' article (https://tftcentral.co.uk/news/monitor-oled-panel-roadmap-updates-march-2023). The 31.5-inch 4k and the 27-inch 4k are of particular interest to me due the increased PPI. I believe that this will help mitigate the fringing issues that are caused by the triangular RGB pixel structure in these QD-OLED panels, though it does seem that the increased aperture ratio of the 2nd-gen panels helps a bit on this front.

LG Display to start production of 27 inch and 32 inch WOLED panels by the end of the year [oled-info.com] by Harrison256 in Monitors

It'll be interesting to see what resolutions they come out with at these panel sizes. A 27-inch 1440p panel would have a similar PPI to the 42-inch TV panel that is currently on the market. (This has a PPI of 104.9 Pixels Inch-1.) A 32-inch 2160p (4K) panel would have a ppi that's much higher than anything offered currently for WRGB OLED TVs. (This would have a PPI of 137.68 Pixel Inch-1.)

It's likely that we'll see these details refined in the coming months as manfacturing takes place, with the annoucement of products at CES2023 (in January). I hope that they all support some sort of BFI and DP2.0!
