X-Star DP2414LED 144Hz 1ms overclockable to 185Hz or more

Post by Q83Ia7ta » 23 Sep 2015, 15:12

I’m sorry for my English.

I got X-Star DP2414LED several days ago just to overclock it and compare with my BenQ XL2411Z.
First of all I don’t like this strobed techs like LightBoost, ULMB, BenQ Blur Reduction and etc and I prefer to play fast twitched FPS. (Input lag is noticeable for me with strobe techs i tried LightBoost & BBR).
I’m also don’t need any Sync techs like FreeSync and G-SYNC. (FPS are 250 or more). Same with panel types. TN is enough for me.
No need to discuss this.
Someday I’ve found information about this monitors (QNIX QX2414LED & X-Star DP2414LED) at Blur Busters Forums and decided to try one of them. They are almost equal. The first one released was QNIX QX2414LED 144Hz 1.5ms with DVI-D only. The pros of DVI-D are may be less input lag and better chances to be overclocked. The next released was X-Star DP2414LED 144Hz 1ms with D-SUB/HDMI/DVI-D inputs and advertised ability to 185Hz overclock.

Overclocked to 185Hz and 200Hz. Got some scanlines at top right side of screen. At 200Hz monitor show white screen after 5-10-15 mins :( so I switched to advertised 185Hz. May be 185Hz because it’s stable.
What I can say for sure is that ghosting at 185Hz is much less than at 144Hz. Overdrive isn’t aggressive if exist :)
I’ve disassembled monitor to view at panel and scaler.
Panel is AUO M240HW01 V8. It’s same as in XL2411Z and in most of 24” 144Hz monitors.
Scaler (processor/main board) is different. May be it’s MST 2403 (MSTAR) - info from EDID.
Default 144Hz timings are:
"1920x1080" 328,890 1920 1968 2000 2080 1080 1084 1089 1098 +hsync +vsync
For XL2411Z timings are:
"1920x1080" 325,080 1920 1944 1976 2056 1080 1083 1088 1098 +hsync +vsync

At 200Hz horizontal scan rate (horizontal frequency) is ~220 kHz and pixel clock is 456 MHz.

I need someone who can read Korean and say for sure is there any options to change overdrive setting in OSD? :) album with manual http://imgur.com/a/J6Dqz
Some photos with packaging, frameskipping test, scanlines, disassembled monitor and etc http://imgur.com/a/Jo496

Not sure
Hard to say is it better or worse than BenQ XL2411Z. Need some more game sessions.

Shipping to Saint Petersburg, Russla from South Korea took 5 days. Well done EMS. Good packaging and speed.
item is http://www.ebay.com/itm/221822303311 and seller called dream-seller.

I wonder if the crashing at 200hz is a heat problem? wonder if you can stick a fan in there to keep it running because that would be cool.

Best I can do there is to to substitute cheap passive radiator to a better one and add holes to case :)

Thanks for idea.

I am too jealous now :(

Can't get higher than 130hz with normal timings on XL2720Z regardless what I try. :(
can't get higher than 145hz with reduced Vblank either. Seems like firmware is locked. Pretty sure its NOT scaler limit because Benq XL2720Z, XL2420Z and XL2411Z can do 2560x1440 via edid override and OSD reports 2560x1440 if you use VT 1497-1502 and reduce HT to 2656.

Sorry to thread hijack.
I assume this is not EDID limit but firmware lock (I know Asus VG248QE can do 150hz also but NOT at 1920x1080, it can do it at 1280x720 and another lower resolution with different timings).

Anyone know bios modification to enable higher refresh rate for benq XL2720Z V4 or (new dump) V5 firmware? Or can EDID edit allow this? You can hex edit raw bin firmware but without knowing how code is....:(

If it was so easy :) I'm also sure it's firware lock.

I have made some shots with Alien Invasion Test with Pursuit Camera Grid at 185Hz:

mirror: https://mega.nz/#!aAcDEJBZ!pF8tvaOf7fm1 ... IN0mJjY-Og

Are there any correct shot?

There is twice less ghosting at 185Hz comparing to 144Hz by eye.

can you do also very high hz with lower resolution ? 1280x720 for example can keep 200hz?

I'm sure it will but I'm gonna replace heat sink (radiator) and holes:

and I hope this will make 200Hz at 1080p stable.

200Hz is stable in games and goes full white screen when picture reaches some off pixels count (to many black at screen) for some short time. At 210Hz unique artifacts and 240Hz another unique artifacts. Funny thing that going back to BenQ XL2411Z at 144Hz makes possible to notice tearing (stable 250fps).
