My package just arrived this morning. First impressions(i'm at work right now so i will use my new custom built box(inside is a photodiode and a bunch of soldered wires and latency measuring hardware which connects BOTH to my oscilloscope and conmpyuter). The accuracy of my oscilloscope goes to the hundedths of 0.01
First impressions of the VG259qm
this is badly tuned because i was comparing my UFO tests with the vg279qm.
1.
at 80 OD, the VG279qm looks SHARPER than the 60 OD of the VG259QM @240hz via UFO test. i got 3.7ms g2g on the vg279qm, i'm guessing @240hz, it's 4-4.2ms g2g at 60 OD @240 for the 25" version. The 60 OD on the vg279qm is SLOWER than the 60 OD on the vg259qm however. then again, why would someone who owns the 27" version of the monitor use OD 60 when OD 80 literally has little to no overshoot?
2. OD 80 is playable at 240hz but the occasional glowing blue artefacts to me is distracting, so OD 60 is FOR SURE the setting to use at 240hz. Also, when i'm going in super sonic speeds, the rocket league ground occasionally glows(it turns white) but no inverse ghosting artefacts. This reminds me of "advanced" setting on the viewsonic elite xg270qg, where the overshoot is SLIGHTLY too high to be playable but it wont' cause any artefacts to show, but u will see a delay in color transition if you go super fast. I'm OCD and if i see any distracting artefacts, to me it's not playable.
3. OD 80 is playable at 280hz and in practice I saw NO artefacts and or delayed color changes(tested this when i was goign in super sonic speed in rocket league) playing only two games of rocket league. I also moved my camera super fast to make sure and i didn't see any artefacts and i didn't. I also didn't see any black level smearing at OD 60 but i can tell when the ball is moving VERY fast, it wasn't as sharp compared to when i'm on OD 80.
so yes, my initial assertion at 280hz. OD 80 HAS to be used @280hz refresh so by default, it's the fastest monitor in the world on its optimal refresh rate oef 280hz. The overshoot just by looking at the UFO test is literally at the
border of what i consider playable at 240hz and above (15%). Anything higher than 15% overshoot, to me it's too distracting
this is one of the mainm reasons why the LG 38gl850-b the 38" ultra wide monitor didn't even break my top 12 because those reviewers claim it has a fast g2g average but the overshoot is above 10%(which at 165hz and below is VERY VERY noticeable). At 240hz, i'm giving a 15% inverse ghosting error rate leeway since overshoot dissipates way faster and the added motion clarity(MPRT) is more powerful as well.
tldr;
this will come down to the overshoot error rate at 280hz. if i find that it's above 15%, this is an instant return.
so from 240hz and below, this monitor is SLOWER than the VG279qm bcuz of how badly tuned the settings are. However, at 280hz, it's faster than the VG279qm because 80 OD is sharper on the 25" version than the 27" version but with more inverse ghosting based off the UFO tests.
this all comes down to the ERROR % measurements of at 280hz on OD 80 .
If it's above 15%, it's unplayable and this would be the worst 240/280hz IPS monitor in my opinion. But if it's at the 13-15%, that is totally acceptable and in practice u probably won't see it(then again, everyone is different). Only IF the FPS is consistently near 280hz or higher.
good news, the input lag at 60hz is snappy. This is just as good as the MSI MAG251rx and the alienware aw2521hf. So the input lag penalty for the 25" version does NOT apply at 60hz fixed refresh compared to its 27" version where input lag at 60hz is horrendous.
will report hard numbers and do rigorus rise time tests once i get home.
