"Price is no Object" Bring-Your-Algorithm Solution

1. PC as box-in-middle
2. Elgato HDMI capture card (~$500) capable of live view; used by esports streamers
3. Reasonable GPU
4. License to Steam Vint App BFI or CRT simulator (works even with a console plugged into Elgato)
5. Configure Vint, but don't use its interpolation (too laggy for live video capture), enable only CRT simulator
6. Configure NVIDIA to NULL with lowest queue (1 frame latency)
7. Plug console into Elgato
8. Plug computer into Display

Voila! 4K 240Hz capable BFI-or-CRT beam simulator for your 720p or 1080p console.

Costs WAY more than a Retrotink 4K, though. Adds a bit of lag because you have a computer-based video processor in the middle.

Extra Tweaks: Instead of 120Hz, use an ultra-low-lag OLED like esports 240Hz, 360Hz or 480Hz OLEDs, which can quickly compensate partially for Elgato/VSYNC lags. 240Hz undoes about 3/4ths of a 60Hz frame of lag, in the final frame delivery. As an additional bonus, perhaps add RTSS Scanline Sync on top, to remove another refresh cycle of VSYNC lag. If you don't enable interpolation, GPU utilization falls enough that beamraced sync apps such as RTSS Scanline Sync and Special K Latent Sync is able to steer a VSYNC OFF tearline above the top edge of the screen, creating a reduced-lag VSYNC mode.

It works but it's a costly BYOA solution. Hopefully this is all miniaturizable into a HDMI dongle or tiny RT-style box by 2030, helped pushed forward by the Blur Busters Open Source Display Initiative.

Chief, what's the RT4K's maximum output Hz at 1080p for a 1080p60 input?

It sounds like 120Hz with BFI/beam emulation, or 144 without. But isn't 180 just within bandwidth, for an extra black frame or beam step?

To answer my own question, I've been told CRT beam emulation can output 1080p240 with a 720p60 input. Else 1080p120 with a 1080p60 input.

Hopefully there'll be an HDMI 2.1 option in future.

Ok, so i was recently told by RetroRGB(YouTube) That when gaming at 1080p with modern consoles, that TINK4K(With t's BFI or maybe CRT simulation) is compatible at either 120hz, 180hz or 240hz for 60fps titles. Yet not 144hz(S90F) or 165hz(S95F). Meanwhile, 240hz QD-OLED TV's obviously don't exist yet so that option is completely out the window.

Yet for 2026, I've been told that 180hz/or 200hz QD-OLED TV's will be arriving, so combined with the current Tink4K using CRT simulation that should reduce motion blur by about 68%(Using 180hz BFI with 60fps games) unless I'm mistaken, with just a little less latency due to the higher refresh rate. You just wont be able to reduce 58% or 64% of the blur with the current OLED's that have 144hz & 165hz.

For now, it's limited to a 50% blur cut for QD-OLED TV's, with probably around double the latency(20ms) overall when you factor in the TINK4K latency, BFI lag & TV game mode lag. Bit of win/lose situation if you ask me, unless i've got latency numbers wrong. But if 20ms is true, than motion clarity will look 50% better, but games will feel a little responsive and enjoyable to control.

CRT's still are still flawless in terms of latency and have no blur obviously. Hopefully we'll get a return to the glory days by 2030 with future TINK4K scalers and 240hz+ QD-OLED TV's, or whatever the latest and greatest TV tech is, at 1440p+.

Make sure you confirm with Mike (owner of RT4K) first. This isn't officially supported in a dual "high rez input, high rez output" situation, even though some modes may work. The 240Hz+ output feature usually requires low-resolution input.

I simply write this because there can be dissapointed users, as the memory bandwidth of RT4K is being pushed to limits.

Whoops, forgot to throw in '@1080p'. I don't plan on using TINK4K's 240hz BFI, just 120hz, and hopefully 180hz next year if that too runs perfectly at 1080p, for 60fps games. With future TINK4K scalers, I'd consider 240hz for future more capable TINK4K scalers that support at least 1080p @240hz bfi, once 240hz QD-OLED TV's actually become a thing. Which I'm guessing will be before 2030?

But for now, and next year. as long as 120hz & 180hz at 1080p are doable.

Also, you mentioned that TINK4K includes TINK4K BFI and now CRT Simulation. Why chose TINK4K BFI over CRT Simulation?
Doesn't CRT simulation have less BFI flicker, less lag and less brightness loss unless I'm mistaken?

I had no idea that CRT simulation within TINK4K only works at 120hz, 180hz & 240hz when gaming at 60fps. But not 144hz & 165hz. In 2026 Spring, with something like the 180hz Samsung 'S95G' flagship QD-OLED, with TINK4K's CRS we'll be able to get >

2ms - TINK4K
5.5ms - 180hz CRT Simulation when gaming at 60fps
10ms - S95G's Game Mode at 60fps

17.5ms - Total lag, with a 66% motion blur reduction. 66% should beat out ANY plasma, yet 17.5ms while not bad or anything, still isn't on par with CRT.

For now, it's just 50% with TINK4K's 120hz bfi when gaming at 60fps, with around 20ms of lag. We're still in a frustrating spot for console gaming. It's either deal with that awful OLED motion blur at 100% with just 10ms of lag. OR, cut down 50%(TINK4K's 120hz CRS @60fps) but deal with around 20ms of lag(Mild flicker, brightness loss & 1080p limitation as well). You either have to put up with games looking more enjoyable, by 50%, to 'look at' in terms of motion clarity, but with heavier less responsive controls...Or, settle for awful blurry motion clarity at 100% but with lighter 'on the dime' controls that get closer to CRT.

Sigh. We probably won't get 240hz QD-OLED TV's by 2030, or 2029 if we're lucky. They're spoon feeding us the hz on a yearly basis it feels like. Like what? 180hz next year, then 200hz, 220hz(Neither of which support Tink4K) & finally 240hz? I want that 75% blur drop now, with 14ms of lag. lol Ideally, QD-OLED with zero motion blur/1ms motion persistence, and with 5ms of input lag would render CRT obsolete. Once I can get blur-free motion clarity, with very low latency on QD-OLED(Or whatever the latest future tech is), that's when I'll finally jump to 77". Just doesn't make sense to do so now when the motion blur will just look magnified and worse at that size.

Uhm, no. We'll get 240Hz OLED TVs once HDMI 2.2 devices launch, like the RTX 6080 & PlayStation 6, in 2027.

Has that actually been confirmed?
PS6 might not be dropping later on in 2028. One YouTuber in particular made it sound like it's going to be a while until 240hz TV's land, and that instead they're going to continue to drip feed the hz, with 180hz(Or 200hz) being a thing for Samsung's flagship 2026 QD-OLED next spring. 180hz is compatible with TINK4K, which cuts down 66% OLED motion blur. Either way, I hope you're right though! I'm getting sick and tired of OLED motion blur. Once you get to 240hz/4ms persistence, motion clarity finally start to look pretty clear and it rivals even the best plasmas. 100% blur removal is obviously the goal, so we can finally kick CRT to the curb for good.

chef may i ask a off topic question?
does dlp projector handle 30fps game smoother than oled with bfi enabled?
some 30fps 3d ps4 game running at 120hz oled with bfi is still very choppy.

2.any comsumer oled display feature rolling scan that i can buy ? does lg oled c1 feature global bfi?
thank you
