Recommendations for Good 1080/1440p 240Hz Monitors (2025)

[thecelicalover]

Currently, I'm using the Dell G2524H and I have had it since February. So far, I've had an okay experience with using it for a few months now, but to be honest, this monitor feels super basic. I really wish this monitor had at least backlight strobing. In my opinion, the panel feels kind of slow. It has an AUO panel inside (M250HAN01.7), which I can confirm because I took apart my monitor. I don't think there was a way to even access the service menu on this monitor. Sadly, I broke the back of my monitor when dissembling it .

The panel is advertised for 280Hz (Overclocked), but it didn't feel truly like 280, it was more like I was playing at 180/200Hz. I ran some Frog Pursuit, and it still had some ghosting at its native refresh rate. I believe it had something to do with VRR, and so I played around with that a little bit. I found out from my experience that having VRR disabled made a difference to motion clarity for this panel. Having the VRR disabled and leaving the OC set at 270Hz + OD set to Super Fast resolved the ghosting problem. It looks better than having VRR enabled at Extreme, though there was a slight faint of inverse ghosting, but it's hard to notice it. The only problem with VRR being disabled is the obvious screen tearing and occasional frame jitter (this happens randomly for some reason). I could use scanline sync to bypass this, of course.

At this point, I might consider the XG2431. Everyone has praised this monitor for having good strobing, but lately, as of last year, there have been some quality-control problems occurring with this monitor. I didn't want to deal with that, which is why I opted to get the G2524H. I know OLED panels are a no-brainer; they're just better than LCDs, but I don't want to spend a lot of cash on getting one. I heard the PG27AQN is the fastest IPS monitor. In the US, it's going for $650 (via Amazon) and yet it's closely within OLED's price range, so what's the point of getting that?

Have you taken any photographs of the disassembly process and/or internals of the display? It would be valuable information.
What's interesting to me is that you mention that your unit came with the M250HAN01.7, which should be much faster than what this review claims

There is still value in LCD displays due to their RGB subpixel layout, ability to use VRR without any light flicker, ability to use backlight strobing with various MPRT values (ranging from 0,3ms to 1ms) and usually higher brightness values.
In terms of raw G2G RT's and contrast ratio, OLED clears LCD.

However, if you are interested in strobing to achieve higher visual clarity in motion, I would avoid getting any KSF/PFS WLED backlight displays such as the PG27AQN due to the extreme red fringing & inability to adjust backlight strobing parameters with the BlurBusters Utility.
FHD displays are still the #1 choice, if backlight strobing is concerned. Displays such as the XG2431, XL2566K, XL2546X+, XL2566X+ should provide a far better backlight strobing experience.
The only other option in the QHD space is the MAG274QRF-QD, which should have far less fringing due to the QD-based WLED backlight and the long-discontinued Dell S2417DG
Both of the aforementioned QHD displays should be <1ms MPRT at 120hz, but I don't have concrete testing data measured with a oscilloscope + probe to back this up.

If you are interested in the cheapest sample & hold performance, then going for 540Hz TN displays such as the AG246FK or XV242F might be a nice option.
Though, at $650, one could also go for a MSI QD-OLED display, provided you are aware of it's cons and willing to adapt to them.

Hope this helps.

So far this is what I have taken. I got more pictures if you wanna see more of them.

These photographs of the dissasembly was done with scrupulous attention to detail, thank you.
It's always interesting to see the internals of different display models.
This LCD display seems to lack shielding of the TCON & scaler units, as it seems to employs plastic instead of aluminium or a stainless steel housing.

Have you taken apart the plastic housing & inspected the TCON, scaler & internal power supply? Curious who manifactures them & what capacitors were used inside.

As a side-note, I apologise for derailing the original intent of your OP

Sadly, I didn't want to take apart the rest of the other components. I'm not much confident when it comes to handling those kind of things. I don't want to take risk of damaging anything of course.

Also if you want to know where I got the source for the teardown and instructions, I got it from Dell main website.

The manual is pretty sparse when it comes to disassembling anyways. I had some trouble trying to pry the back cover out to look at the inside of the monitor. I thought I broke it at first .

Understandable. Regardless, thank you for providing photographs!
Great find! I was also on a journey on researching into internals of displays recently & noticed that Dell seems to provide diassembly guides on their website. A noble feat, in the age where disposable electronics & planned obsolescence are prevalent.

Just as a confirmation, is the middle section (shielding) made out of plastic or metal? I'm somewhat leaning onto the idea that it's plastic, but I cannot say for certain..

As far as I know, I believe the TCON shield is made out of metal. I was touching the surface of the shielding, so I didn't believe it would be plastic. And close inspection of it appears to be metal.
