Welcome to ZisWorks

ZisWorks is an electronics design company focusing on displays and PC gaming equipment.

Our newest product, the x28 display, is the first avialable 4k@120Hz display. Additionally, it offers 1080p@240Hz, 720p@300Hz, and 540p@480Hz. 28" TN and 39" MVA flavors are avaialble. With an opensource flexible backlight driver with high-frequency pwm, pwm-free, strobe, and scanning modes, it is an experimenter's dream. In true ZWS spirit, all parts are individually purchasable for labratory use :)

Kit Frequenty Asked Questions

4k120Hz diplay FAQ

Can this drive panel X?

If panel X is M280DGJ or V390DK1-LS1 then yes, otherwise no.

What is image quality like?

Image quality in the 4k modes is basically the same as any other monitor using this panel (only one 28" 4k panel was mass-produced)

Image quality in the fast modes is very minorly degraded, but still good overall.

Are lower resolutions fuzzy??

No, integer scaling is used, so the display is always sharp. Subpixel-aware rendering (truetype fonts) do not have the desired visual effect and should be disabled.

Does 10bpc require lower refresh rates?

No, 10bpc is supported without reducing refresh rates, including 4k120Hz.

Are both DP inputs needed?

Both DP inputs are needed for the 4k120Hz mode. 4k60, 1080p240, 720p300, and 540p480 all only require one DP input.

What is the highest resolution 120Hz that one DP can handle

2160*2160@120Hz.

What is the highest refresh rate at 4k that one DP can handle

60Hz.

What's the deal with chroma subsampling and display stream compression?

Neither scheme is used, 30bpp in the RGB colorspace. Chroma subsampling (often labled as 4:2:2 or 4:2:0) does not apply to the RGB colorspace

Can it be overclocked?

Not really, the TCON is already pushing the limits of what the panel can handle.


Backlight driver FAQ

DP2LVDS FAQ

Can this drive panel X?

Check the panel datasheet. If it uses LVDS interface with 2 or 4 channels, then the answer is yes.

Can ZWS provide cables for panel X?

It depends. There are a few common pinouts, so if it is similar to cables that we already have in-stock, then yes. Otherwise, making custom cables is probably more expensive than it is worth.

Read the making-of story making-of story here to see some of the milestones and decisions during development of the x28/x39 electronics. :)

03 September 2017

The LinusTechTips video is now live :)

03 September 2017

All support has been moved to the x28/x39 user group.

20 August 2017

I've been doing an ask-me-anything at reddit.

18 August 2017

The site has been updated with various improvements, with new product listings, renders, and descriptions. The store is now linked ot the main site and downloads section for documentation now exists. Despite the bare website and LTT video not yet being public, sales for the first day have been strong and totaled around $7400. Most interest has been in the 39" upgrade kits.

17 August 2017

In anticipation for the LTT and blurbusters reviews, the store has gone live.
