I have one of those, and can personally confirm that it won't run at OP's specs.
This is a better option that can handle a much higher pixel clock. I've used it up to 2048x1536 without issue.
Just got my StarTech DP2VGAHD20 yesterday, it's capable of 375Mhz. It would run your 1920x1440@75Hz perfectly and does not cost as much as a DPU3000 or other synaptics based adapter, considering that wavy effect is not the monitors fault.
I figured I'd hit both of your responses in one go since I just got out of a meeting:
For PC CRTs, CRU auto-populates everything perfectly for every CRT I've given it. It's only TVs where I've had to mess around with it to get things right (but even that's unnecessary when Arcade OSD does things much easier and with instant results).
I have a few AMD cards in a few different systems, but my main desktop has an R9 270X, and that's been my best purchase so far. For anything I would ever want to use it for that I somehow someway can't get my 2080 Super to do the heavy lifting, the 270X can handle without a care in the world.
Worth noting, the R9 only powers my 15kHz CRTs. My PC CRTs are handled directly by my 2080 Super, care of a StarTech DisplayPort to VGA adapter. It says it only handles up to 1920x1080 over VGA, but it lies; I've pushed it as high as 2048x1536. It's rock solid.
Those are good for HDMI consoles and lower end monitors but can't handle enough bandwidth to run higher specced monitors at their full resolution/refresh rate potential.
Better to go with a good DP to VGA converter for that. I recommend the StarTech DP2VGAHD20.
While it's a DisplayPort adapter and not HDMI, this is the best I've found so far. I've fed it 120 Hz 2560x240, 75 Hz 1920x1440, and 60 Hz 2048x1536 without issue. Any other adapter I've tried has failed at handling at least the latter two, if not all three.
You’ll come to find that resolution and refresh options are a mess with adapters. Especially the cheap ones. To avoid that problem I got a more expensive adapter.
As well I think you’re looking for a displayport to vga if you’re using a modern gpu. This is the one that I and others use: adapter
There are cheaper options but you’ll have to go digging.
StarTech makes one on amazon that I think is DP to HDMI and VGA. It’s super good and supports lots of resolutions @ different refresh rates. Amazon has easy returns so it may be worth checking out
I don't know if proper conversion at that framerate from HDMI to VGA is possible. I use this, which is a DisplayPort to VGA adapter. It handles my 120hz output just fine, though the lowest res I've tested it at is 800x600 since that's the lowest my monitor can scan.
That monitor can do better than that - should be able to push at least 80hz at 1440p. You just need a good Displayport to VGA adapter, then you can set up whatever resolution you want with the Nvidia control panel.
Get one of these Startech adapters - it's rated pretty close to your monitor's max specs:
startech displayport to vga that I use
people sell their crts not too expensive on ebay, $100-200 maybe, i got 1024x768 vga one in that range
stick with 4:3, see if your gpu has any displayport outputs, i used this adapter and keep in mind youre getting them for the different look from led screens which also means the frame might be dispositioned/misshapen or weirdly colored. the tube should have some buttons to tweak the shape, position and color+brightness
It does for my purposes! My dell p780 works great at 640x480@120 and . If you need more bandwidth than that, I like the startech displayport to vga adapter here. The tendak hdmi is nice to have since it works with consoles, even though you need to mess around with screen size for 16:9 games.
My PVM is a 1271Q (which accepts RGB input but NOT component input, which probably would have made this easier)
My setup is:
nVidia GTX 1080 (I believe later nVidia cards don't work)
-> Displayport to VGA adapter (this Startech one)
-> Extron RGB109 Unit
-> component cables (using the R,G,B and a fourth one for sync)
-> the PVM itself.
I use the nVidia Control Panel to push 240p or 224p signal at 15khz horizontal refresh. It works great once the pains of figuring it out are over!
This one should serve you well. It's a popular recommendation on here and can handle plenty of bandwidth for high res/refresh. I'm using it right now with my 1070, works great.
That post you're referring to with the Tendak is bizarre. I definitely did not expect that cheap little adapter to be able to handle that kind of resolution since generally HDMI to VGA converters can't handle as much juice as DP to VGA. And also someone else commented saying theirs fried itself when they tried to run high res, lol. So who knows what the deal with that is.
I've been using this one. It doesn't completely max out the monitor's specs, but it works well enough. I can run 2048x1536 at 80hz, 1600x1200 at 100hz, and 1440x1080 at 120hz. Black levels look good. It's displayport rather than HDMI but it should be fine with your video card.

I also have a Walmart brand HDMI converter that's not quite as good as the Startech but much better than I thought it would be. It runs 1600x1200x85hz no problem, although YMMV since I don't know how consistent Walmart is with their products.
delock 62967 will let you max out at 2048x1536 @ 75hz. So will this Star Tech adapter will do the job its available at a bunch of places online if you dont want to buy from amazon https://www.amazon.com/StarTech-com-DisplayPort-HDMI-VGA-Adapter/dp/B0849FTBXQ?pd_rd_w=Ues0t&pf_rd_p=f8048a1b-0abf-4d1a-a91b-cb558d45ad96&pf_rd_r=4KZ3PTMY4PNY82JGMZB6&pd_rd_r=3b14f96e-18bb-4340-832d-8f9c03fcbede&pd_rd_wg=RxGEs&...
That's gonna look epic. What's your GPU, though? If it's new it's probably got DVI-D not DVI-I, which means you will need an active DAC. If that's the case then this is the one I recommend. It can handle high resolutions/refresh rates.
Allows full range on my Viewsonic p95f+. Can do 1280x1024 @ 100Hz, 1024x768 @ 133Hz, 800x600@160Hz and then go all the way up to 2048 x 1536 at 68 Hz. The respective resolutions/refresh rates are all dependent on the horizontal refresh rate of the monitor. It didn't have issues pushing my 110kHz horizontal refresh rate maximums.
DisplayPort to VGA converter. Specifically, this one.
Slight copy paste here, but:
Delock 62967 : https://www.reichelt.com/de/en/adapter-displayport-1-2-male-vga-female-black-delock-62967-p211925.html?r=1

The 62967 tends to cap out between 330 and 340mhz, the Startech at ~375, and the 87685 has been shown to repeatedly manage 500+ (540 being the usually cited point where it gives up).
As to the current issue of freezing up, have you attempted to plug it in before powering your PC up, and/or do you have another PC with DP out that you can test it with?
Yeah, lots of us have them. Myself and others have gotten ours here.
Another good option is the StarTech DP2VGAHD20 which can allegedly handle up to 375MHz. I've got one of those on the way right now actually.
Would be the goto DACs I would suggest for if you want higher refresh/resolution output to a PC CRT. HDMI is nice if you don't have high requirements, but they're only rated for ~165mhz and while they will go past this, will rarely get much higher than 200. The DP adapters above will all do 300+ if you need that, with each getting progressively higher. The 62967 tends to cap out between 330 and 340mhz, the Startech at ~375, and the 87685 has been shown to repeatedly manage 500+ (540 being the usually cited point where it gives up).
Of course, each gets progressively more expensive, with the last one being a full on MST rather than just a DAC. What best suits your use case is the one you should go with, all will offer the same level of quality in terms of picture output, and all are lagless.
To get an idea of what your actual requirements will be, here's a calculator: https://tomverbeure.github.io/video_timings_calculator
Toss in which ever resolution and refresh combos you think you'd want to make use of, and be sure to pay attention to 2 numbers:
Pixel clock, for at what point the above adapters can support, and H Freq, for at what point your monitor can no longer support a given combo. In the case of your P275, that's going to be 130khz, and you're going to be wanting to look at the CVT column rather than either of the RB ones.
And of course feel free to look around for a place to buy that may be preferable to your location.
If you want a DP-VGA adapter that can do 1920 x 1440, you can get one from Amazon here:
I can use it at 2048 x 1536 @ 75 Hz no problem.
The Delock 87685 is functionally identical to the Sunix. You can buy it here.
You only really need one of those if you want to push a super top-of-the-line 130+kHz monitor to the limit, though. For a cheaper option I recommend the StarTech DP2VGAHD20, it can handle up to around 375MHz pixel clock which is plenty for most monitors.
I've got a StarTech DP2VGAHD20 and Delock 62967. They're both good options. But the displayport connector on the Delock is a little too short and some people have problems getting a good connection.
Not quite up to the mark, but I was able to get 2048x1536@82Hz out of a StarTech DP2VGAHD20, but it didn't seem to go above that, even though my monitor can through DVI-I -> VGA.
I commented a little while ago about it here
Just another data point here for anyone who stumbles across this thread:
I ordered a StarTech DP2VGAHD20 from their Amazon store on July 29th, got it today and popped it open, and can confirm that it has the ITE IT6564FN.
In terms of performance, it seems to be able to do up to 2048x1536@82Hz. I couldn't get it higher than that, even though my monitor can do 2048x1536@85Hz directly from the DVI-I port on my GTX 970. This might be because I'm just using standard CRU resolutions, and I need to fiddle with the advanced resolution settings to get 85Hz. I can, however, also get 1920x1440@90Hz to work fine, which means it should be capable of supporting the max resolutions for most other monitors.
I'll also note that connecting the monitor to the adapter before connecting the adapter to the GPU's DP causes Windows 10 to identify the monitor correctly as a GDM-F520, and provides a bunch of high resolutions by default. Connecting the adapter to the GPU and then connecting the monitor causes Windows 10 to recognise the display as the adapter itself (or something) instead.
Had the same monitor with the same problem. If you have a DP port, get a DP to VGA converter instead. (this one is good)
If you need to use an HDMI to VGA adapter you can remove one of the EDID pins from a VGA extension cable, or port saver. I removed Pin 12 and it fixed the issue. Here is a pic.
Maybe a different HDMI to VGA would work fine. But not sure.
A good component to VGA transcoder is going to cost 60$ minimum unfortunately. I actually play N64 games on my VGA monitor sometimes and I just emulate from my pc and play at the max resolution of the monitor. I use this startech displayport to vga converter
I also actually have a RGB modded n64 with a built in line doubler so I've tried connecting the N64 to the VGA monitor with a good component to VGA converter but it doesn't look anywhere near as good as emulation, 240p is too low a resolution to look good on such a sharp VGA monitor. So generally unless you are planning on doing something where you want the absolute most minimal amount of input lag like Super Mario 64 speedrunning or competitive N64 Super Smash Bros I would just say emulate if you want to use your VGA monitor.
Looks like there is one left in stock on Amazon UK right now:
CRU is Custom Resolution Utility.
The StarTech DP2VGAHD20 will serve you well:
StarTech DP2VGAHD20 is the one to get.
Letting you know I just had this arrive and it appears to have resolved the issue so far
It's showing $27.69USD for me with Prime shipping.
The dongle would be your limiting factor on resolution there, Startech DP2VGAHD20 is the current coolness https://www.amazon.com/StarTech-com-DisplayPort-HDMI-VGA-Adapter/dp/B0849FTBXQ
Hi everyone, I've been looking for a higher bandwidth hdmi to VGA adapter for use with my Dell P911. I've found this one recommended:
But unfortunately it doesn't seem to be available on Amazon UK, I can only find this one:
Does anyone know if the two adapters have the same spec, just with a different shell, or is the one I found lower specced than the other (was looking for one that can do ~ 1200x1600 @85hz. Thanks.
Pick up a DP to VGA converter (I recommend this one) and you will be good to go.
I recommend this one, it can handle upwards of 375MHz bandwidth which is more than enough for most monitors.
What's the highest res/refresh you've tested with it?
This one is known to be a good one, it's been tested to work upwards of 375MHz bandwidth.
you mean this? https://www.amazon.com/StarTech-com-DisplayPort-HDMI-VGA-Adapter/dp/B0849FTBXQ/ref=sr_1_1?dchild=1&keywords=startech+dp2vgahd20&qid=1620338361&sr=8-1
StarTech DP2VGAHD20. Handles 375MHz. It's on sale right now too!
I recommend either the StarTech DP2VGAHD20 or Delock 62967. I have both and they're good. The DP connector on the Delock is a little short, though, which can cause problems getting it plugged all the way into your GPU properly.
