How do you add 15KHz RGBHV compatibilty to LCD VGA monitors?

How do you add 15KHz RGBHV compatibilty to 31KHz LCD VGA monitors?

I have a broken acer VGA LCD monitor that needs repairs. Since I'm going to be opening it up to try and fix it, how do you add 15KHz RGBHV compatibility or even 15KHz RGBS compatibility? I know converters exist but I would like to avoid them for now.

I want to use it for some projects, mostly a vertical PS1 Namco Museum monitor (the games have a vertical monitor mode). I haven't tried RGsB on it yet. Any help would be highly appreciated!

 

Oh, that's easy: Remove the panel and controller board and replace it with panel+controller from a monitor that is already 15kHz RGBHV/RGBS compatible.

 

So basically get a new monitor? I would do that but I can't find any modern monitors that support 15KHz.

The monitor also has black lines going through it towards the bottom of the screen. Does anyone know how to fix it? It's an acer V173 VGA monitor for Windows Vista.

 

Yes - put it in the bin and get a working monitor. And a Framemeister if you insist on using LCD. Or just get a Sony PVM broadcast monitor.

 

It was given to me by my cousin. I would like a monitor that can be used with vertical arcade games. I can't afford an XRGB mini. I've been seeing $90 15KHz RGBS/RGBHV/RGsB to 31Khz VGA converters on eBay lately. I have no idea if any of them are good or not.

 

Not really.

Either save up for a Framemeister, or get a PVM. Which you can turn on its side. Probably for less than the $90 converter... definitely less than the converter AND a new monitor.

 

I would love to have a Framemeister. Does it have a VGA and/or DVI-A output? I have this old Envision LCD VGA monitor from my childhood that I use on my Dreamcast and my childhood Windows 98 rig. I could use that for a vertical monitor.

I looked into PVMs before but I'm having a hard time finding one in my area.

I've seen these DVD0 upscalers for $100-$200 cheaper than the Framemeister on eBay. Are they any good?

 

They're cheaper for a reason. And $200 cheaper than Framemeister IS around $90.

Oops, good point - you need XRGB-3 for VGA!

Try the cheaper option if you want, but it's always going to be a compromise. Find someone who'll ship a PVM on eBay, or keep an eye on Craigslist etc. Post a WTB on forums - you never know!

 

I was referring to the $400 ones on eBay. The DVD0s I was looking at were $180-$300.

How good is the XRGB-3 compared to the XRGB mini? If it isn't as good as the mini, then maybe one of those cheap HDMI to VGA converters designed for laptops would work with the framemeister.

 

Forget the LCD. Buy a CRT (TV) that supports 15khz horizontal scan and enjoy the video the way god intended.

You have many choices - arcade monitors, Sony PVM/BVM/GVM, etc. Shipping will kill you though, a 20" Sony PVM weighs about 80lbs

 

With the XRGB mini's built-in scanline generator, the only thing a CRT is good for is Duck Hunt, and that can still be played on LCDs via the Virtual Console. Games can look amazing on LCDs, you just need the correct cables and/or proper equipment to correct poor manufacturing decisions/cost saving measures on LCDs.

LCD is all I have save for an old RF-Only CRT and an old Gateway VGA CRT monitor. The CRTs belong to my parents and I don't have room for a giant CRT atm. I'm gonna stick with my 32" HDTV since it does 240p over Component video quite well. I do plan on getting a CRT just for light gun games but it won't be for a long time.

Besides, with an LCD, I get more options like everything hooked up to one TV, resolutions up to 4K, 16:9/16:10 aspect ratios, every connection known to man (some require HDMI converters), and all sorts of picture and sound controls. Also, they aren't full of dangerous gases and weigh a ton less. Can your CRT do that?

EDIT: My light bill isn't through the roof since I use an LCD. It uses less power than a CRT. #PowerSavingFeatures

 

LCDs have somthing called native resolution. So unless you can find a 640x480 LCD, the image WILL be upscaled to fill the vertical. It will not look like the original. Period.

 

That's why you use a proper upscaler so it looks better. It looks perfectly like the original on mine, even through a $60 RGB SCART to HDMI converter with a built-in upscaler.

You must be plugging Composite video and S-Video cables directly into the LCD HDTV, which always looks bad. CRTs tend to hide the mess created by those lower quality cables. If you use better cables, such as RGB SCART/JP-21 cables and true digital HDMI mods, games look amazing, even without scanlines.

A monitor with a native resolution of 240p will be about 5" or less. The number of pixels on-screen doesn't matter to me as long as it looks sharp and has no blurring, color bleeding, and/or other artifacts. A proper upscaler will fix resolution issues.

This part of my last post was meant as a joke. I'm sorry if it offended anyone.

 

I'm not sure if the problem you're describing is the one I'm thinking of (a picture is usually very helpful in these cases), but that could indicate problems somewhere between the inputs of the line drivers and the horizontal driving lines of the panels. Since all of this is integrated in the panel itself, the fix would be to replace the panel.

 

I've never used one of those $300 upscaler boxes. However I have seen what upscaling effects software emulators produce. For example ZSNES has something like 8 different upscaling filters, and most of them generate funky results. Good results, but somewhat distorted. I have a feeling there isnt a perfect upscaling algorithm that will work in all cases. If you want higher res graphics, the artist must redraw it from scratch!

The bottom line is there's a reason why broadcast monitor's like Sony PVM are highly sought items.

 

ZSNES has an upscaling feature? I'll have to try it out sometime.

I'm not sure how upscalers work but a good one like the XRGB Mini Framemeister can upscale with no lag and can even add scanlines. From what I've seen, it looks just like it would on a PVM. It is something I plan on getting one day.

I want a PVM but I can never find one locally and I literally have no room for it. I would really only use it for light guns and the Famicom 3D System.
